We invite public and students to observe the planets, Lunar and Solar eclipses and other

celestial objects. The department has a Seismological Laboratory where the study of seismic

waves (Earth Quake) is being carried out.

The Vision of the department is to develop it as a Centre of Excellence in Materials

Science and Technology by submitting the DST FIST (Phase II) and UGC projects. It is planned

to start the courses in the emerging areas like Mathematical Modeling Computational Physics

and Computer Simulation. Industry-Departmental joint research projects will be undertaken. The

department will take up joint research projects in the field of Nanomaterials with High Energy

Materials Research Laboratory (HEMRL, DRDD, Pune) and BARC, Mumbai.

Research currently being pursued:

(I) Fuel cells (CNTs), solar cells, storage cells and purification of water

Synthesis of nanosize materials has got tremendous importance because of their

appli-cations in the fields of science and technology. We work on the nanosize coatings

on transpar-ent conducting oxides (TCOs), metal chalcogenides and carbon nanotubes for

various applica-tions. Mainly chemical deposition techniques such as spray pyrolysis,

electrodeposition and chemical vapour deposition are being used for production of above

said nanomaterials.

TiO2 is the important material prepared by spray pyrolysis which is being used for

photodegradation of contaminants present in the water, thereby purifying the water. Fe

doped CdSe produced by electrodeposition technique has successfully being used in the

recharge-able storage cell.

Research activities will further be strengthened to obtain good efficiency of fuel cell, to

remove toxins in water at greater extent and to improve the perfor-mance of rechargeable

storage cell and solar Cells.

(II) Sensors, DSSCs and supercapacitors

Using electrodeposited RuO2 and poly aniline thin films, good supercapacitor values have

been obtained. Similarly new metal oxides such as Bi2O3, Fe2O3, BiFeO3, and ferrite thin

films have been used for first time to get reasonable supercapacitive values. Using

chemically deposited ZnO thin films LPG sensors have been developed. Also

Polyaniline/ Cd chalco-genide thin film junctions have been successfully used for sensing

LPG gas at room tempera-ture.

Using TiO2 and ZnO thin films, the Dye solar cells with conversion efficiency of 4.5%

has been reported.

(III) Aerogels: New class of Nano structured Materials

As the name implies, aerogels consist of more than 98% air and less than 2% solid

materials with a refractive index varying from 1.01 to 1.1. They are nanostructured

materials having well controlled pore and particle sizes in the range 1 to 100 nm. Because

of their nanostructured nature, they have the combination of unusual property of porosity

and visible transparency. They have several novel applications in nuclear reactor, nuclear

fusion energy, thermal and acoustic insulation systems and heterogeneous catalysis. In

general, aerogels are produced by sol-gel processing followed by supercritical drying.

(IV) Nanomaterials, Electrochromic and Electrical devices

The most properties of traditional ceramics stem from the fact that their raw material in

natural clay is nanosized. Besides, because of sharpness of the human eye, the size of

pigment particles must be smaller than 500 nm to homogeneously colour enamols and

glasses. Potters and ceramists have thus been using nanoscience for thousands of years,

but a new generation of engineered nanomaterials has been in development.

The main impetus would be developing nanomaterials for the following advanced

technologies. Pigments for the electrochromic industry (metal oxides), fluorescent

markers (Quantum Dots), photonic crystals, light emitting devices, miniatured silicon

chips

(V) Holographic study of nanomaterials

Holography is an exciting branch of discipline of optics. The progress in holography has

been made because of surprising facts either of the refolding of figure can be used to

reconstruct the original wave front.

We are using this technique as a non-destructive tool to investigate the purity of the

samples Gold, Silver like noble metals. Similarly we are using the same to investigate

thickness of thin film, surface deformations, elastic constants, diffusion coefficient etc.

Our plane is to develop and upgrade the Holographic Laboratory to study the different

materials by Speckle Pattern Interferometry.

The applications of Holographic-as well as Speckle Pattern Interferometry are used for

Human beings, like light scattering effect on edible fats to investigate adulterations in

foods, oils etc. The Electronic Speckle Pattern Interferometry will be used to detect the

abnormalities in human beings.

(VI) Superconductors and fuel cells

The research is going on the four different areas like fuel cell, superconductivity,

biodiesel and magnetic refrigeration.

In the area of fuel cell, BICUVOX solid electrolyte was synthesized and characterized by

various techniques for its structural, morphological analysis and impedance measurement

to study conduction mechanism.

Synthesis of MgB2 superconducting thin films by a novel technique called as

electrocrystallization was invented by our group. The electrophoretic technique was also

developed to deposit the MgB2 in the thick film form. The synthesis of superconducting

MgB2 bulk samples was successfully attempted without using any pressurized or inert gas

environ-ment

Taking into consideration the need of society, a new area of interest related to Jatropha

oil, as a bio-fuel in the vehicle was developed. Taking into consideration the different

tempera-ture conditions which affect the viscosity of the Jatropha oil an attempt was

made to determine the viscosity of the same.

Another new area of interest developed is magnetic refrigeration. We have successfully

synthesized the MnAs thin films by novel electrochemical route.

(VII) Nanocrystalline Ferrites, Ferroelectrics and Composites

Nanocrystalline materials are defined as polycrystalline materials with grain sizes upto

about 100 nm. These materials are widely used as catalysis, sensor, aerosols, filters,

biomedi-cal, magnetic, dielectric, optical, electronic structural, ceramics and others

metallurgical appli-cations.

Fine particle systems have been form to show an enhancement in the value of coerciv-ity

(varies as D6). The ferromagnetic properties of material such as saturation magnetization

and Curie temperature are considerably reduced influenced by changes in inter atomic

dis-tances at the interfacial region as compare to crystalline region.

(VIII) Microwave Devices

Study of microwave properties of thick and thin film as well as bulk materials such as

polymers, ferrites, oxides, dispersed carbon films, magnetodielectric materials,

manganites is going on our laboratory. Furthet: these matetials are applied for the

formation of microstrip integrated circuits such as patch antenna, resonators, circuilators,

filtet:s etc. Study on use of biomaterials (e.g. various seeds, leafs etc.) as microwave

sensor is in progress.

Collaborations

Department has several scientific collaborations with national and international research

Institutes and Universities.

Abstract

Magnetoelectric phenomenon has been observed in several single phase materials in

which simultaneous electric and magnetic ordering coexists and in two phase composites in

which the participating phases are ferrite and ferroelectric. Magnetoelectric composites were

prepared by ceramic method. The presence of ferrite and ferroelectric phases were confirmed by

X-ray diffraction technique. The variation resistivity and thermoelectric power of the composite

with temperature was studied. The variation of dielectric constant with frequency and with

temperature at different frequencies was studied. Ac conductivity is derived from dielectric

constant and loss tangent. The nature of conduction has been discussed with the help of polaron

hopping model. Finally the value of magnetoelectric conversion factor was calculated.

Abstract

Group V-VI compounds have remarkable applications in thermoelectric, optoelectronic,

photoelectrochemical devices and ample efforts have been made to grow the material with

required properties. The post-deposition treatment is a very important task to be carried out to

modify the material properties. We report on the electron beam induced modifications in the

electrodeposited group Sb2S3 thin films. Irradiation is the process by which, an item is exposed

to radiation. The exposure can be intentional, sometimes to serve a specific purpose. The

electrodeposited Sb2S3 thin films were irradiated by an electron beam. The irradiation

experiments were carried out at 7 MeV linear electron accelerators (LINAC) set up at Bhabha

Atomic Research Center (BARC), Mumbai, India. The samples were irradiated by these electron

pulses at a repetition rate of 12 pulses per second for about 6.5 seconds, accounting for a

cumulative dose of about 10 kGy.

In the present investigation, the first effort is focused on the exploitation of electron

beam irradiation as a tool to induce modifications in the optical, morphological, and structural

and wettability studies of Sb2S3 thin films. The films have been synthesized via an easy and

simple electrodeposition process using stainless steel and fluorine doped tin oxide (FTO) coated

glass as substrates, in potentiostatic mode. Sodium thiosulphate (Na2S2O3) as a precursor

sources and ethylene diamine tetra acetic acid (EDTA) was used as a complexing agent. The as-

deposited and irradiated films were further characterized for their structural and morphological

studies. by XRD, SEM, optical absorption and surface wettability. The obtained decrease in the

bandgap might be due to the creation of shallow defect levels near the conduction band as a

result of irradiation. The ion bombardment increases the crystallinity of films due to induced

defects and therefore the Raman bands whose intensity depends on the crystallinity also get

increased correspondingly. In addition, there is an increase in the grain size of the films due to

irradiation, leading to the increase in contact angle. Irradiation of the Sb2S3 films results in

superhydrophobic surface

Abstract

Tin oxide (SnO2) thin films have diverse applications in Optical, Electrical,

Electrochromic and Energy Device technology. The SnO2 films can serve as transparent

electrical conductors, anti reflecting coatings for solar cells and low emittance window coatings

used for smart window technology. Recently, W: SnO2 thin films have been widely accepted for

the electrochromic applications, which hinges on the ability of the material to sustain mix

conduction of ions as well as electrons, proving to be a suitable candidate for ionic intercalation

and deintercalation properties.

The films have been deposited onto FTO coated highly conducting glass substrates

having sheet resistance 20 Ω/, maintained at various deposition temperatures (350 - 450oC) by

using Spray Pyrolysis Technique (SPT) from 0.05M stannic chloride and tungsten oxide as

precursor solutions. The depositions conditions were optimized at their proper values. An

investigation of the highly structural sensitive property makes it possible to gain insight into the

electrochemical properties of the metal film. Such investigation is important for energy

converting devices. The films are almost transparent (85%) in visible wavelength range and well

adherent to the substrates. In the present investigation, the electrochromic properties of W:SnO2

have been discussed. The electrochemical studies of the films were carried out by using cyclic

voltammetry and chronoamperometry technique using a simple three electrode EC cells

and 0.1 N H2SO4 as an electrolyte. The films exhibited cathodic electrochromism, changing

colour from bluish gray to colourless. The colouration efficiency (18.5cm2/C) was also

determined. Cyclic voltammetry (VersaStat-II EG&G make) was used to determine intercalation

charge capacity as well as redox potential of the film. The chronoamperometry was used to

determine response time for colouration and bleaching processes of the film.

Abstract

The synthesis of Al-doped ZnO thin films by spray CVD technique offers an ideal

system to explore the effect of Al dopants into ZnO matrix. The deposition process is analogous

to aerosol assisted chemical vapor deposition rather than droplet deposition by spray pyrolysis

technique. The properties of the films are governed by the impurity additives of Aluminium

Chloride as dopant source to the non-aqueous base precursor solution of zinc acetate. The

dopant concentrations were varied in the range of 1 at% to 1.5 at% in steps of 0.2. As deposited

films were highly homogeneous, uniform and well adherent to the glass substrate. The

crystalline structure and orientation of film were characterized X-ray diffraction technique.

Surface morphology of films has also been analyzed by field emission scanning micrographs. It

is observed that Aluminium dopant strongly affect surface morphology of ZnO thin film. It

reveals transition morphology from triangular pyramidal shaped into enhanced hexagonal grains

induced by different doping concentration. Among all doping range of Al, 1.3 at% shows

enhanced (002) peak intensity which implies improvement in crystallinity. It indicates higher

conductivity with optimum spectral distribution of transmittance significantly better than most

TCO’s. The optical band gap widening is occurred through its dependence on the carrier

concentration in the form of the Moss –Burstein effect.

Abstract

Silver ultra thin films of thickness in the range of 50 nm to 130 nm are deposited

uniformly on a glass substrate using thermal evaporation technique and controlled iodization

was carried out for selected duration of time in the range of 2 to 13 min at room temperature

(RT). As deposited Ag and iodized films were characterized using x-Ray Diffraction (XRD),

Atomic Force Microscope (AFM), and UV Visible spectrophotometry (UV-Vis). While the

unionized films are X-ray amorphous in keeping with their quasi-continuous nature and 2D

islanded structure, briefly iodized films showed characteristic AgI structure. The 2D AFM

pictures showed that the spherical shape of pure silver does not change appreciably upon

iodization. Optical absorption spectra in the UV-Visible wave length region give an evidence for

the presence of Mie scattering particles through surface plasmon resonance whose peak

positions and intensities depend sensitively upon thickness of Ag films. Usually Surface

plasmon resonance peak is observed in the wavelength range of 420-600 nm. In this case,

Plasmon peak show a clear shift in the wavelength as the film thickness increases from 50 nm to

130 nm. Finally, an interesting and unique Surface Plasmon Resonance (SPR) is observed as the

ultra-thin films are progressively iodized. These Ag and AgI films could be promising

candidates for plasmonic and nanophotonic applications such as optical data storage, Biosensor

etc.

Abstract

To enhance the stability and lifetime of CdTe/CdS solar cells, intrinsic material

properties as well as external influences need to be addressed. A deep understanding of the

relationship between electrically active impurities and device performance is of great

importance for achieving solar cell efficiencies higher than those demonstrated so far. The

investigation of the effect of impurities originating from the source materials has received very

little interest despite its potentially crucial impact on the performance of polycrystalline CdTe

thin film solar cells. It was reported [1, 2] that identical solar cells made from 5N (99.999%) to

7N (99.99999%) pure Cd and Te source materials have resulted in the solar cells with different

efficiencies. We hereby investigate and report the preparation and characterization

methodologies of high pure (5N to 7N) Cd and Te materials and their respective salts required

for the fabrication of CdS/CdTe thin film solar cells using electrochemical deposition technique.

The 5N and 7N pure Cd and Te were prepared by indigenous Automated Zone Refiner [3]. The

Cadmium and Tellurium compounds were prepared by conventional procedures which will be

presented in detail. The purity of the as prepared high pure materials and there salts was

assessed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The aim of this

research work is to develop the process technology for the preparation and characterization of

high pure starting materials to produce solar cells through the electrochemical deposition

technique, which are used later to fabricate solar panels to produce environmental friendly non-

conventional energy. Hitherto, the high pure Cd and Te materials and their compounds are being

imported and are not available in the country in the referent purity level.

Abstract

The effective harnessing / utilization of the environmentally benign, abundantly available, solar

energy available with characteristic solar-spectrum, calls for identification / synthesis materials with

stringent specification in terms of their physical properties and the dimension. The range of application

of thin film of materials on a variety of insulating/ conducting substrates is very large with its surface

coverage ranging from nano-dots in the field of nano-electronics to large-area of several square meters of

coatings such as window glasses. The properties of thin film of a material depends on the on the

crystallite-size and /or thickness and are also dictated by the experimental deposition conditions. The

chemically deposited metal chalcogenide thin films have bright prospects as low-cost solar control

coating application. With their superior solar control characteristics, they could find widespread

applications in countries with warm climate.For instance, thin films of PbS and CuxS on glass substrates,

deposited from chemical baths are shown to possess excellent solar control characteristics-superior or

comparable to the metallic solar control coatings. Cadmium sulfide (CdS), is a II-VI compound direct

band gap semiconductor with a band gap 2.42eV at room temperature. It is a potential n-type window

material with p-type cadmium telluride (CdTe)/copper indium di-selenide (CuInSe2) a absorber of the p-n

junction, a basic element of heterojunction thin film solar cell (TFSC). CdTe/CdSheterojunction TSFC

with efficiency 16.5% have been recently reported. Recently CdS has important role to play as useful

material with applicationin photodetectors, thin-film FET, gas sensors, TCO in optoelectronic

devicesalso. CdS thin-filmhas been deposited by chemical bath deposition (CBD) method that is as a

low-cost technique, easily scalable useful for large-area deposition. Uniformly deposited thin-films of

CdS on microscopic slides using high-purity cadmium sulfate, thiourea and ammonium hydroxide in

aqueous basic medium with optimized growth conditions: pH, concentration of reacting species,

temperature, stirring-rate, orientation of the substrate and deposition-time.Good quality thin-film has

been obtained. The CdS-thin filmwas subjected to X–ray analysis using X‘PERT PROdiffractometer with

Cu Kα. Well defined peaks 111, 200, 220, 311, 222, 400 of cubic phase and the peaks 100, 002, 101,102,

110, 103, 112 the hexagonal phase exhibit the presence of mixed phase (polymorphism).The grain-size

estimate of the thin film have been calculated using Sherrerformula and thickness of the film have been

measured using profilometer and strain has been calculated. The SEM studies of the will be presented.

Abstract

The CdSe and Al:CdSe nanocrystalline thin films of various compositions have been

deposited onto the amorphous, ZnO and FTO coated glass substrates using a spray pyrolysis

technique. CdSe and Al:CdSe films deposited on amorphous glass substrates have been

characterized by XRD, which indicates that the films are polycrystalline in nature. These films

grown on ZnO substrates are characterized for their morphological study. The

photoelectrochemical investigations have been carried out using the cell configuration CdSe/1M

(Na2S–S–NaOH)/C and Al:CdSe/1M (Na2S–S–NaOH)/C for studying the current–voltage (I–V)

characteristics in dark and under illumination, photovoltaic output characteristic, capacitance

voltage characteristic and spectral response. The capacitance–voltage measurements indicate the

films exhibit n-type conductivity with flat band potential decreases from -0.986 to -1.05 V/SCE.

The junction quality factor in light (nl), series and shunt resistance (Rs and Rsh), fill factor (FF)

and efficiency (η) for the cell have been estimated. After Al doping, efficiency of PEC solar cell

is found to be improved from 0.18% to 4.1%.

Abstract

We report on a Raman spectroscopic study of chemically synthesized graphene oxide

(GO) and reduced graphene oxide (rGO). The chemical and crystallographic identification of

GO and rGO were qualified by Raman spectroscopy. The Raman spectra of GO and rGO

presented strong Graphitic (G) peaks at 1600 and 2745 cm-1 (G and G’ peaks, respectively) due

to the doubly degenerate zone center E2g mode; and defected (D) peak at 1360 cm-1 because of

the zone-boundary phonons as it don’t satisfy Raman fundamental selection rule. The Raman

spectra showed much intense ‘D’ peak of GO compared to that of rGO, while the major intense

G’ peak of rGO relative to GO. This result confirmed the chemical reduction of graphene oxide.

Hydrothermal Method

Abstract

This study demonstrates a novel solution-based simple hydrothermal process to design

porous nanoballs structured CuO thin films. In the synthesis, starting copper salt (sulphate) is

first converted to copper complex ion to avoid precipitation. The porous nanoballs structured

CuO thin films were obtained by the heating of copper complex ion solution in a hydrothermal

autoclave at low temperature (353K). The prepared films were characterized by X- ray

diffraction (XRD), Scanning Electron Microscope (SEM), Fourier Transform Infra Red

Spectroscopy (FT-IR), Raman and surface wettability techniques. The XRD pattern pointed the

nanocrystaline nature of CuO thin films. The CuO formation was confirmed from FTIR and

Raman studies. SEM images revealed the highly porous nanoballs-like construction. The

electrochemical properties of CuO in 1M Na2SO4 electrolyte showed the pseudocapacitive

behavior with specific capacitance of 534 Fg-1

. The specific energy and specific power values

were 98 Wh/Kg and 8.6 KW/Kg, respectively. This study proposes that hydrothermally

deposited CuO thin film electrode is a promising candidate for electrochemical supercapacitor.

Abstract

The microwave part of the electromagnetic spectrum can be used to study the moisture

related changes occurring in the leaves. The microwave react with the biomaterials, therefore the

biophysical status of the vegetation can be studied which will be very useful for management of

natural resources. The microstrip component being in planar form can offer an alternative

compact device for biomaterial studies. The use of overlay technique offers further

planarisation. The thick film λ/2 L section microstrip rejection filter was fabricated using screen

printing technology on alumina substrate with silver as a metallization and thin film λ/2 L

section microstrip rejection filter was fabricated using vacuum evaporation and electroplating

with copper as a metallization. The filters have a high rejection at the resonant frequency and

this is very sensitive to the medium above the filter. This aspect can be used to study the

material placed as in touch overlay on the filter. In this paper the changes in the rejection

properties in the X band and Ku band of thick and thin film λ/2 L section microstrip rejection

filter due to leaf overlay is reported. Croton (Green leaf with yellow spots and streaks) has been

used as in-touch overlay. A comparative study has been done between the response of the thick

and thin film filter as a function of frequency. Frequency dependent and metallization dependent

effects are observed.

Abstract

Polymer based (polyaniline-polypyrrole) heterojunction was fabricated by

electrodeposition method. Room temperature detection of LPG is carried out by heterojunction

based on the change in capacitance. Diffusion of the charge carriers at the interface of

heterojunction gives rise to junction capacitance. When heterojunction is operated in reverse

bias, junction capacitance decreases with increase reverse biased voltage. The polyaniline-

polypyrrole heterojunction was exposed to different LPG concentrations. The change in the

junction capacitance is observed. The flat band potentials for polymer based heterojunction in

air, and at 260 ppm, 520 ppm and 780 ppm of LPG are 0.032, 0.056, 0.1 and 0.13 V

respectively. This indicates the polyaniline-polypyrrole heterojunction is a potential candidate

for room temperature LPG detection.

properties of titanium dioxide (TiO2) thin films synthesized at room temperature using

successive ionic layer adsorption and reaction (SILAR) technique. As a cost effective and metal

free alternative to conventional ruthenium complex, we introduce Rose Bengal dye as the photo

sensitizer in the dye-sensitized solar cells (DSSC). The synthesized TiO2 thin films were

characterized using X- ray diffraction, Scanning electron microscopy (SEM), Fourier Transform

Infrared (FT-IR) spectroscopy and UV-Vis absorption spectroscopy. The XRD pattern indicated

the formation of anatase phase of a TiO2 thin film with low intensity (101) peak having

crystallite size 41 nm. The SEM micrographs revealed the presence of interconnected

nanograins having diameter around 20 nm. FT-IR analysis detected the Ti-O and Ti-O-Ti peaks

at 334 and 255 cm-1

intensities, respectively. The shift from UV to visible region was observed

in absorbance curve due to dye loading on pristine TiO2 for Rose Bengal. Optical band gap of

pristine TiO2 was found to be 3.10 eV. Rose Bengal dye showed better results having Isc, Voc

and efficiency values as 0.03 mAcm-2, 234.2 mV and 0.006 %, respectively in polyiodide

electrolyte at 50 mW/cm2 illumination.

Abstract

Here we review the current status of magnetoelectric (ME) multiferroics and ME

composite thin/thick films. The magnetostrictive-piezoelectric composites exhibit strong ME

property through elastic interactions occurring at the interface of these two phases. So far, strong

magneto-elastic and elasto-electric coupling has been investigated through optimization of

material properties and proper design of transducer structures with different connectivity

schemes. These developments have led to magnetoelectric structures that provide high

sensitivity over a varying range of frequency and DC bias fields enabling the possibility of

practical applications such as a transducer, field sensor and energy harvester.The multiferroic

ME films in comparison with bulk ME composites have some unique advantages andshow

higher magnitude of ME response. In ME composite films, thickness of the films is one of the

important factors to haveenough signal. However, most of all reported ME nanocomposite

structured films in literature are limited in overall thicknesswhich might be related to interface

strain resulting from difference in thermal expansion mismatch between individual phasesand

the substrate. Here, we introduced noble ME composite film fabrication technique, aerosol

deposition (AD) to overcome theseproblems. The success in AD fabrication and characterization

of ME composite films with various microstructure such as 3-2, 2-2connectivity are discussed.

Abstract:

Fuel cell is electrochemical device which converts chemical energy of fuel directly in to

electrical energy. Strontium doped lanthanum manganite pervoskite oxides LSM (La1-xSrxMnO3-

δ) have been widely studied in recent years due to their widely interesting applications in solid

oxide fuel cell (SOFC). It has thermal and chemical stability and reliability with electrolyte

materials.

Many research groups have synthesized LSM materials in bulk form. The solid oxide

fuel cell technology has been hindered due to high operating temperatures of fuel cell. The

operating temperature of SOFC can be reduced by synthesizing fuel cell material in thin film

form by different routes. There are several routes to synthesis pervoskite structured materials.

In the present study we have synthesized strontium-doped lanthanum manganite

(La0.9Sr0.1MnO3-δ) by using spray pyrolysis technique. The deposition of thin films via spray

pyrolysis involves spraying metallic salt solution on a heated substrate. The solution droplets

reach the substrate surface, where solvent evaporation and the decomposition of the salt occurs,

forming a film. The film morphology and thickness depends on the volume of solution sprayed

and substrate temperature.

In the present work the strontium-doped manganite lanthanum ( La0.9Sr0.1MnO3-δ-

LSM ) were synthesized by spray pyrolytic technique in thin film form on glass substrate by

optimizing the spray parameters such as substrate temperature 300oC, spray rate (40ml/hr), to

obtain pin-hole free, crack free and dense thin film. Scratch the powder from glass substrate and

sintered at 600oC and characterized by X-ray diffractometry (XRD).

Abstract

The Fiber optics communication industry uses various types of optical devices like

multilayer interference structure of thin films, wavelength selective interference filters, Fiber

Bragg grating interference filters, optical couplers, optical switches etc. They are very important

and critical elements in modern optics that often determine the overall efficiency of equipment.

There are no common methods how to design a device having specific properties. So the

characteristic parameters of devices can be designed and optimized by using mathematical

models. The priority task for the developers is to obtain maximal selectivity and maintainability

of such devices with high performance.

Abstract:

The recent progress in applying micro controllers to control equipments requires a large

number of low cost, highly reliable, temperature sensors. Thick film NTC ceramics are expected

to meet this requirement because of high reproducibility, flexibility and compatibility, apart

from cost effective method of fabrication. Thick film NTC thermistors due to its cost effective

fabrication and planarization aspects are expected to meet the temperature sensing requirement

of many hybrid circuits. The Ni(1-x)ZnxMn2O4 and ZnFexMn2-xO4 NTC ceramic have been

prepared by chemical co-precipitation method and thick films delineated on alumina substrate

by screen printing method. X-ray diffraction studies show the ceramic being cubic spinel

structure with predominant (311) plane. The variation in grain size with the substitution of zinc

and iron was observed by scanning electron microscopy. The microwave properties of these

thick film NTC ceramic was studied by waveguide reflectometer method. The composition

Abstract

The growth of zinc selenide thin films by using a potentiostatic and potentiodynamic

modes of electrochemical deposition method on fluorine doped tin oxide (FTO) substrate was

studied. In order to obtain the zinc selenide thin films, the preparative conditions, such as

concentration, pH of cationic precursors, deposition time and scan rate were optimized. The

growth of the thin films was found to uniform with blackish brown colour. The films were

characterized by various experimental methods for structural, surface morphological and optical

properties. The films obtained with potentiostatic mode were nanocrystalline, while a film with

potentiodynamic mode shows amorphous nature. The surface of the films was smooth. The

absorbance of the film was found to be high in visible spectral range. The optical band gap

varies with mode of deposition.

Abstract

The paper reports, effect of electrochemical cycling on the structural, morphological

and supercapacitive properties of Mn3O4 thin films deposited using modified chemical bath

deposition method. The X–ray diffraction studies showed conversion of Mn3O4 into MnO2 after

2000 cycles. The conversion of corn nanoflakes into uniformly distributed nanoflakes is

observed from scanning electron microscopy (SEM). The contact angle of 5° for as deposited

films is increased to 40° for the cycled films indicating increased porosity of the film surface.

The supercapacitive study carried out using CV shows specific capacitances of 174 Fg–1 and 185

Fg–1 for 1st and 2000th cycles respectively. The charge–discharge studies indicate ideal

capacitive behavior.

Abstract:

Nuclear radiation are present in the earth’s environment since from the formation of

earth .The isotopes of uranium, thorium with their decay products and potassium (40K) are

widely distributed in the earth’s crust. These along with the cosmic radiation are the sources of

natural radiation in the environment to which the life on the earth is exposed. At surface the

contribution of cosmic rays is low (˂ 10%) and increases with altitude. In the present study the

activity were measured with G-M counter and NaI(Tl) crystal scintillation detector and both are

calibrated with standard source of 137

Cs. The efficiency of G-M counter measures to be 5.3% and

that of NaI (Tl) is 70%.

Both the detectors were mounted side by side on the terrace at height 5 meters from the

ground at a place Kankvali (15059’N; 72

034’E) and observation were carried out. To minimize

the statistical fluctuations observations were recorded for every 3 minute in G-M counter and for

every 10 minute in NaI(Tl) detector and it’s average over an hour was taken. Average counts for

3 minute for G-M counter and 30 second for NaI(Tl) detector in an hour were plotted for 24

hours IST. Observed counts were corrected for geometrical and intrinsic efficiency of both the

counters. Compton scattered electrons counts were subtracted from NaI(Tl) detector counts at

Compton edge. From observed counts and dimensions of the detectors the activity in Bq/m2

were obtained. Using standard conversion factor for the G-M tube specification, the observed

activity was converted into dose rate in mSv/year.

Observed average activity at 5 meter height measures to be 1673 Bq/m2 with G-M

counter and 1509 Bq/m2 with NaI(Tl) crystal detector and is found to be 23% less than that

measured at the surface at the place of observation. The average dose rate is measured to be

0.8092 mSv/year and is well within prescribed limits recommended by ICRP, which is 1

mSv/year for non-nuclear energy workers and 20 mSv/year for nuclear energy workers. There

observes small diurnal variation in activity with peak at early three-four morning hours and in

the evening two-three hours after sunset with a standard deviation of 4.5%.

Abstract:

M type barium and strontium hexaferrite powders were synthesized by co-precipitation

method using chloride sources. The synthesis condition dependant structural and microwave

properties were studied. It was observed that, the saturation magnetization of barium hexaferrite

was lower than strontium hexaferrite. For both BaFe12O19 and SrFe12O19 samples, the saturation

magnetization increases with increase in pH of the precipitate formed during the synthesis. The

DC magnetization agrees well with the crystallite size. The microwave complex permittivity

(ε*) and permeability (µ*) of BaFe12O19 and SrFe12O19 was investigated by waveguide

reflectometer technique. All the samples synthesized at different conditions show almost similar

variation with frequency, the difference is in the magnitudes of ε* and µ*. The dielectric

constant of 11:1 barium hexaferrite pellets lies from 6.56 to 23.945. At 9 GHz, all the sample

show higher ε’ and decreased up to 12 GHz. The dielectric loss ε” of barium hexaferrites varies

from 0.0015 to 0.95. The Strontium hexaferrite show low dielectric loss in Ku band than that of

in X band. Compared to barium hexaferrite, the strontium hexaferrite pellets show lower

dielectric constant and permeability and lesser dispersion in the X band but more dispersion in

Abstract

Ferrites are the key materials for RAM applications. The ferrite nanoparticle provides

large surface area for microwave absorption. Hexaferrites are the class of ferrites which exhibits

high anisotropy, large coercivity and large saturation magnetization. Ba4Co2Fe36O60 mixed

hexaferrite shows larger anisotropy making them very useful in the microwave region of the

electromagnetic spectrum. This paper reports the synthesis by co precipitation and

characterization of nanostructured Ba4Co2Fe36O60 . Microwave properties of Ba4Co2Fe36O60

mixed hexaferrite in the ku band region is reported. The powder was pelletised and sintered at

9000c for 6h. The hexaferrite phase obtained with the synthesized powder was confirmed by X-

ray diffraction studies. The average crystallite size was ~ 70nm to 100nm.The surface

morphology of Ba4Co2Fe36O60 nanopowder was studied by scanning electron microscope.

Uniform spherical particles were obtained. The microwave absorbance and transmittance of

Ba4Co2Fe36O60 bulk was studied by waveguide reflectometer. It has been observed that the

microwave absorption enhances dramatically. Electrical resistance was measured by using two

probe methods. Resistance vs temperature plot shows semiconducting behavior at higher

Abstract:

With the development of radar, microwave communication technology and especially

the need for anti-electro-magnetic interference coatings, self-concealing technology and

microwave darkrooms, the study of electromagnetic wave absorbing materials has increased in

recent years. The microwave-absorbing properties of Sr0.6Ca0.4Mn1-xCoxO3 (0.0≤x≤1.0) powders

have been studied in the frequency range of 8–12 GHz at room temperature. The perovskite

structure was confirmed by x ray diffraction. The structural changes have been identified by

scanning electron microscopy. As cobalt content increases in the strontium calcium manganite

then grain size decreases from ~1.3µm to ~0.55µm for x=0.2 and x=0.6 respectively. The high

frequency (8 GHz -12 GHz) absorbance and reflectance of cobalt doped strontium calcium

manganite were investigated and were found to be dependent on synthesis parameters. The

Abstract

Nanostructured semiconducting zinc sulphide (ZnS) thin films were deposited on glass

substrate by relatively simple, quick and cost effective chemical bath deposition (CBD) method.

The characterization of as deposited thin films was carried out for the structural, compositional,

surface morphological and gas sensing properties using X-ray diffraction (XRD), E-DAX,

scanning electron microscopy (SEM) and gas sensing static unit. The mechanism of hydrogen

sensing by the ZnS thin film is attributed to the reaction on the material surface or removal of

chemisorbed oxygen from the film surface by testing gas. The sensor gave optimum responses

to different gases at different operating temperatures. The surface misfits operating temperature

can affect the microstructure and gas sensing performance of the sensor. The resistance

responses of the nanocrystalline ZnS thin films were measured by exposing as deposited film to

different gases namely ammonia (NH3), carbon dioxide (CO2), ethanol (C2H5OH), hydrogen

sulphide (H2S), liquid petroleum gas (LPG), hydrogen (H2) and chlorine (Cl2). It was found that

the sensors exhibited various sensing responses to these gases at different operating temperature.

The results demonstrated that nanocrystalline ZnS thin film can be used as a new type of gas

sensing material which has a high sensitivity and good selectivity to Chlorine (Cl2) gas for 500

ppm at room temperature.

B. H. Patil, G. S. Gund, S. S. Shinde and C. D. Lokhande*



Abstract

Polyaniline (PANI) thin films were prepared by simple and inexpensive successive ionic

layer adsorption and reaction (SILAR) method in presence and absence of Triton X-100 as a

surfactant using ammonium peroxidisulphate as an oxidant. The prepared PANI thin films were

characterized using FT-IR, UV–VIS, SEM and cyclic voltammetry studies. The FT-IR spectra

confirmed the corresponding functional groups of polyaniline. The UV–VIS spectra demonstrate

the π−π* electronic transition of the conjugated molecules. The PANI thin films prepared with

surfactant exhibited different morphology compared to bare PANI. The specific capacitances

(SC) of the prepared PANI electrodes were calculated using cyclic voltammetry technique, the

PANI electrode prepared with Triton X-100 exhibited higher SC of 1040 F/g compared to SC of

bare PANI (637 F/g). Hence, the PANI thin film prepared with Triton X-100 surfactant is found

to be suitable electrode material for redox supercapacitor.

Abstracts

Yttrium-doped BaCeO3 (BCY), a solid state ion conductor which exhibits proton

conductivity under some conditions, is used as an electrolyte in a solid oxide fuel cell (SOFC).

In present work, nanocrystalline Yttrium doped Barium Cerate (BCY) thin films have been

successfully deposited on to alumina substrates by simple and economical spray pyrolysis

technique (SPT). These films were characterized for their thermal gravimetrical analysis (TGA-

DTA), structural, surface morphological and RAMAN spectra. The X-ray diffraction (XRD)

studies for SPT deposited BCY thin films revealed the highly crystalline orthorhombic structure.

The scanning electron microscope (SEM) patterns showed dense morphology which is very

useful for electrolyte. 460 cm-1 peak of RAMAN spectra confirmed the BCY phase. From the

above results it can be concluded that SPT grown BCY thin films, show excellent properties for

electrolyte application in fuel cell.

Abstract

In the present study we reported, the methytrimethoxysilane based superhydrophobic

silica coatings on different metal substrates for anticorrosion purpose with the simple dip

coating method. The aim of this study is to test the capability of sol–gel coatings to improve

corrosion resistance of the different metal substrates. It is found that the coatings are effective at

preventing corrosion of copper, aluminium and bronze substrates. In addition, the

reproducibility is very good and we can get the similar result in every experiment under the

preparation conditions. Overall, the strategy presented herein may provide a generic approach

for fabrication of protective coatings on different metallic surfaces. The prepared samples are

characterized with FESEM to determine surface morphology, FTIR to know chemical

composition and water contact angle for hydrophobicity of coatings.

Abstract

The objective of the present work was to prepare carbon xerogels using resorcinol and

formaldehyde. The polycondensation of resorcinol with formaldehyde under alkaline

conditions results in the formation of surface functionalized polymer "clusters". The

covalent crosslinking of these "clusters" produces gels which are processed under ambient

conditions to obtain low density, organic xerogels . The xerogels are transparent, dark red

in colour, and consist of interconnected colloidal-like particles with diameters of

approximately 30 nm. The polymerization mechanism, structure and properties of the

resorcinol-formaldehyde xerogels are similar to the sol-gel processing of silica. The carbon

xerogels formed have very low electrical resistane (~6 ohm). Further this xerogel is

characterized using different characterization methods, such as Fourier Transform Infrared

Spectroscopy (FTIR) for chemical composition, Scanning Electron Microscopy (SEM) to study

surface morphology, X-ray Diffraction (XRD) for phase determination.

Abstract

Holographic interferometry technique used to study the surface deformation of

electrodeposited copper sulphide thin films. It is concerned with the formation and interpretation

of fringe patterns, which appears when a wave generated at some earlier time and stored in a

hologram is later reconstructed by interfering with comparison wave. The proposed technique

uses double exposure holographic interferometry (DEHI) together with simple mathematical

relation, which allows immediate finding of stress, mass deposited, stress to substrate and

thickness of thin film. It must be further noted that, fringe spacing changes with time of

deposition as well as solution concentration. Raman spectra and FT-IR spectra show sharp peaks

of as deposited CuS thin films. The structural study (XRD) is carried out for the confirmation.

Abstract

Thermoelectric study of Sb (III) doped bismuth tellurium selenide ,Bi2-x Sbx(Te1-xSex)3

thin films were done.They are deposited by Arrested Precipitation Technique (APT). These thin

films were prepared using a complexing agent triethanolamine (TEA) and a reducing agent

sodium sulphite to avoid hydroxide formation of bismuth precursor Bi (NO3)3 and antimony

precursor (SbCl3) in aqueous medium to favor the reaction with Te2-

and Se2-

The preparative conditions such as PH, concentration of precursors, temperature, rate of agitation

and time were finalized at initial stages of deposition. As deposited films were annealed at

constant temperature (373K) in muffle furnace and then characterized for optostructural,

morphological, thermoelectric and figure of merit (ZT). The results demonstrate that the Bi2-x

Abstract

Cadmium oxide has attracted significant attention for various applications. Cadmium

oxide is an n-type semiconductor which has a cubic structure and a narrower direct band gap of

2.2–2.5eV with inherent properties such as high electrical conductivity, high carrier

concentration and high transparency. CdO thin film were preparedobtained by using several

techniques, such as spray pyrolysis, sputtering, solvothermal method, sol-gel and chemical bath

deposition (CBD). The CdO/Cd(OH)2 films have been deposited onto the glass substrate by

Chemical Bath Deposition Method. The 0.1M Cd (NO3)2 was used as a source of zinc and

Acqueous ammonia were added to make it alkaline. Further addition of excess ammonia

dissolved the turbidity and made the solution clear and transparent as solution became super-

saturated. The glass microslides were used as substrates, which were cleaned with labogent

solution and chromic acid, followed by rinsing with distilled water.The glass microslides were

taken out after 24 hrs and keeping it under tap water to remove loosely bonded ions and we got

uniform and homogeneous film of CdO/Cd(OH)2.

Similarly, the same bath has been prepared; this bath was kept on magnetic stirrer with

hot plate and maintained at 800

C. The uniform and homogeneous films were obtained after

nearly 3 hrs. As deposited films were annealed at 4000 C. for 1 hr in muffle furnace to get CdO

with good adherence

Abstract

Stoichiometric Ba0.9Sr0.1TiO3 (BST) powder was prepared by standard double

sintering ceramic method using A.R. grade carbonates of Barium, Strontium and Titanium

oxide in powder form. Prepared sample was characterized by XRD and SEM. XRD pattern

confirm formation of single phase polycrystalline structure without any impurity and with

tetragonal structure. The SEM micrograph clearly revels, formation of single phase without

other phase caused by chemical reaction. Uneven grain boundaries were also observed.

Electrical resistivity (ρ) as a function of temperature was determined by two probe method.

Electrical resistivity shows that the sample have semiconducting in nature.

The dielectric properties were studied as a function of frequency at room temperature

and also studied by changing temperature in the frequency range (1kHz-5MHz). The dielectric

constant (έ) is maximum at low frequency, which is due to space charge polarisation and

becomes independent at higher frequency. Dielectric constant increases with increase in

temperature in beginning reaches to maximum value at Tc and decreases with further increase

in temperature which revels the transition of phase from ferroelectric to paraelectric. A.C.

conductivity study shows that conduction in sample is due to small polaron hopping.

where x=0.1, 0.2 and 0.3 was prepared using A. R. grade nickel carbonate, cadmium carbonate ,

cobalt carbonate and iron oxide in stoichiometric proportion by solid state reaction. The

structural and electric properties of NiCoCd ferrite samples were investigated. A cubic spinel

structure of NiCoCd ferrite was determined by X-ray Diffraction technique. The lattice

parameter increases while the crystallite size was reduces with increase in cadmium content. The

average grain size of the samples was studied by Scanning Electron Microscope (SEM). It is

observed that average grain size increases with increase in cadmium content. The D.C resistivity

(ρ) was measured as a function of temperature in the range 300K-1073K. The variation of D.C

resistivity with temperature for all samples shows semiconducting behavior. Dielectric

properties with variation of frequency were studied. Dielectric constant (έ) was decreases with

increase in cadmium. The temperature dependence dielectric constant was studied in frequency

range 1 KHz-1MHz. The Curie temperature decreases with increasing cadmium content. A.C.

conductivity (σac) is derived from dielectric constant (έ) and loss tangent (tanδ) values. Linear

graph of A.C. conductivity against frequency confirms that hopping is due to small polaron.

with rhombohedral crystal structure. Morphological behavior reveals overgrown grains in doped

films with decrease in grain size. Optical analysis shows the increase in direct band-gap energy

from 2.11 to 2.17 eV. The addition of Au induces a decrease in the electrical resistivity of films,

Abstract

Cobalt ferrite thin films (CoFe2O4) were synthesized by chemical spray pyrolysis

technique on to preheated glass substrates using cobalt nitrate and ferric nitrate as precursors.

Influence of substrate temperature on to structural, morphological, electrical, dielectrical and

impedance properties were studied. The annealed (600 oC) films are polycrystalline in nature

having spinel cubic crystal structure along (311) preferential orientation. Thermoelectric power

shows that CoFe2O4 is n-type in nature. Average optical reflectance and transmittance of

CoFe2O4 thin films in the visible region is about 15 % and 35 % respectively. Optical band gap

of deposited films are of about 2.4 eV. The dielectric constant, loss tangent and ac conductivity

against frequency decreases with substrate temperature and then increases. Electrical resistivity

measurements were carried out using the two-probe method. Electrical resistivity decreases with

increasing temperature showing semiconducting nature of prepared ferrite thin films. The good

quality films of CoFe2O4 are useful for various gas sensors.

Abstract:

Naturally occurring primordial radio nuclides of uranium, thorium, and actinium decay

series along with potassium-40 are preset at trace levels in all soils and rocks. Depending on the

composition of soils and rocks their concentration varies from place to place on earth. Building

materials derived from different sources also contain varying concentrations of natural

radioactivity. Radioactivity of all natural radioactive nuclides along with small percentage of

cosmic rays forms the background nuclear radiation. Radon (222Rn), a radioactive inert gas

produced from disintegration of radium-226 atoms, is globally a major source of natural

radiation exposure. Radon is emitted from soil and materials into air and it’s concentration in

closed air increases than that of in open air.

In this framework, measurements have been carried out with a Geiger- Mueller LND

7224 detector, calibrated by Cs-137 standard source. Observations were taken for 24 hours in a

day and for 17 different days inside the house at place, Kankvali (15059’N; 72

034’E ). Average

indoor activity measures to be 2669 Bq/m2 and it is 10.87 percent higher than that of outdoor

activity at the same place. During 24 hours in a day activity fluctuate by small amount about the

mean value with standard deviation of 6.92 %.Diurnal variation in activity shows peak in

activity during early morning hours and during evening three-four hours. Average indoor dose

rate measure to be 1.216 mSv/year and it is below the maximum dose limit set by ICRP.

Abstract

Tin dioxide (SnO2), a direct wide band gap (Eg = 3.6 eV) n-type semiconductor with a

large excitonic binding energy (130 meV), is one of the most promising functional materials,

electrically conducting, optically transparent and has wide range of applications. It exhibits

excellent optical, electrical, chemical properties and high thermal stability.

In the present report, we report a simple and viable hydrothermal synthesis of novel fern

like architecture of SnO2. In this investigation the SnO2 thin film was deposited using Stannic

Chloride (II) and Sodium hydroxide as precursor solutions with ethanol as a solvent. The

deposition time period was optimized at reaction temperature 140 oC. The deposited thin film

was characterized using characterization techniques as like, XRD, SEM, FT-RAMAN, and UV-

Visible spectroscopy. The XRD pattern reveals the formation of crystalline SnO2. The SEM

image exhibits uniformly formed hierarchical fern-like structure. This kind of morphology is

believed to be useful for the applications like gas sensors and solar cells as it offers higher

Abstract

Assessments of the surface free energy of low-energy solids by means of easy to

perform contact angle measurements would be very attractive. The surface free energy of a solid

determines its surface and interfacial behavior in process like wetting and adhesion which is

crucial for silica aerogels in case of organic liquid absorption and transportation of chemicals at

nano-scale for biotechnological and medical applications. The “equation of state” approach of

Neumann’s equation which uses liquid drop contact angle with the solid surface as a single

parameter for estimation of surface free energy of the solid. The surface free energy of the silica

aerogels with different other liquids of known surface tension values and low volatility was

measured and the estimate of the change in the surface free energy was achieved. The flexible,

superhydrophobic and low density silica aerogels was prepared using a two stage sol-gel process

of methyrtrimethoxysilane as a precursor. The flexible silica aerogels have been characterized

by bulk density, volume shrinkage (%), porosity (%) and thermal conductivity. The quantitative

analysis of hydrophobicity was done by measuring the water drop contact angles of the surface

of aerogel. The micro-structural and elemental analyses studies were carried out using

transmission electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy.

The thermal stability of the aerogel was checked by thermo-gravimetric and differential

scanning colorimetric (TGA-DSC) analysis. Silica monolithic aerogels with ultralow density 40

Kg/m3 and low thermal conductivity ~0.072 W/mK has been obtained by supercritical drying

process.

Abstract

A novel superhydrophobic and pencil scratch resistant film on glass based on silica

nanoparticles was successfully achieved from coating the methyltrimethoxysilane as a precursor

by spin coating technique. The polyvinyl pyrollidine (PVP) was used for inducing the

nanoporous network. The nanoparticles of silica and strongest bonding between them played a

role in the formation of nanoporous network which is accountable for the high optical

transmission of the film in the visible region. The contact angle (CA) reached up to ~ 169 ±1º

for 10 µL volume of the water droplet sliding angle was achieved minimum to 4 ±1°. Non-

wetting property was tested by keeping the film in the humidity chamber for over 60 days. The

silica film exhibited resistance to scratches by a pencil of 5H grade as per the ASTM D 3363

method. The feasible potential approach towards the fabrication of the superhydrophobic silica

film with tailored nanoporous network and scratch resistant asset is indispensable for many

practical applications. Needle like surface morphology was revealed by atomic force microscopy

suggested the existence of the hard and superhydrophobic nature of the silica films.

technique. Dielectric dispersion having Maxwell–Wagner-type interfacial polarization has been

observed for cobalt ferrite samples. Dielectric constant and loss tangent are found to decrease

with frequency. AC conductivity measurements suggest that the conduction is due to small

polaron hopping. D C resistivity is found increased with substitution Mn. The activation energy

obtained from in paramagnetic region is found to be more than that in ferromagnetic region.

characterize electrodeposited Cd1−xMnxSe thin films. The X-ray diffraction (XRD) analysis

reveals that the films Cd1−xMnxSe are polycrystalline in nature. Scanning electron microscopy

(SEM) study for the sample deposited at optimized preparative parameters reveals that all grains

uniformly distributed over the surface of stainless steel substrate indicates well defined growth of

polycrystalline Cd–Mn–Se material. Optical absorption shows the presence of direct transition

Abstract

Highly sensitive nanocrystalline undoped and Sb doped SnO2 thin films with different Sb-

concentrations have been deposited by spray pyrolysis and corresponding sensitivity for different

toxic gases is test out. The X-Ray photoelectron spectroscopy (XPS), Field emission scanning

electron microscopy (FE-SEM) is used to characterize structural, morphological properties of the

films. The XPS measurements confirm that, films are oxygen deficient and oxygen deficiency

increases with increase in Sb concentration. The FE-SEM images reveal randomly oriented

needle-shaped polyhedron like grains of Sb:SnO2 film. The sensitivity of the undoped and Sb

doped SnO2 sensors are examined within operating temperature range of 250- 450oC for various

toxic gases. Pure SnO2 thin film shows relatively higher sensitivity than Sb:SnO2. These results

demonstrate that pure nanocrystalline SnO2 thin film has higher gas sensitivity and can be used

as potential sensing material for gas sensor fabrication.

Abstract

A simple, novel and selective spectrophotometric method was described for the

determination of nickel(II). The method is based on synergistic extraction of nickel(II) with 1-

(2’,4’-dinitro aminophenyl)-4,4,6-trimethyl-1,4-dihydropyrimidine-2-thiol, [2’,4’-dinitro

APTPT] and pyridine. Nickel(II) reacts with 2’,4’-dinitro APTPT and forms a green coloured

complex at pH 9.2. The absorbance of coloured complex was measured at 660 nm and coloured

complex is stable for more than 48 h. The system obeyed Beer’s law in the concentration range

of 5 to 50 µg mL-1

of nickel(II) as evaluated by Ringbom’s plot method was 10 to 40 µg mL-1

with an excellent linearity and a correlation coefficient of 0.999. The molar absorptivity and

Sandell’s sensitivity of the extractive species were found to be 1.64 x 103 dm

0.0585 µg cm-2

in presence of pyridine, and 7.4 x 102 dm

-2 in absence

of pyridine, respectively. The composition of nickel(II)-2’,4’-dinitro APTPT-pyridine was

established by slope ratio method, mole ratio method and Job’s method of continuous variation.

It was found that Metal:Ligand:Synergent (M:L:Sy) ratio is 1:2:2. To assess precision and

accuracy of the developed method, determinations were carried out at n = 5. The relative

standard deviation of all measurements does not exceed 0.16 %. The effects of various cations

and anions on selectivity of the method were investigated. The extraction method is almost free

from interferences and has been successfully applied to the determination of nickel(II) in

synthetic mixtures and alloys.

Abstract

In this, Zinc Oxide (ZnO) thin films were prepared onto glass at low substrate

temperature by advanced spray pyrolysis technique. The effect of core temperature variation on

microstructure, surface morphology and optical properties were investigated with X-ray

diffractometry, atomic force microscopy, UV–visible spectrophotometer and Photoluminescence

(PL) spectroscopy, respectively. Films grown at low core temperature (< 573 K) are found to be

amorphous in nature; while the films grown at higher core temperatures (≥ 598 K) exhibits

polycrystalline phase. The film prepared at 598 K is highly oriented along (002) plane with

hexagonal wurtzite phase and exhibits good crystallinity. AFM studies revealed much smaller

RMS roughness values (< 3 nm) for polycrystalline ZnO films than that (~ 40 nm) of the ZnO

film deposited by conventional spray pyrolysis technique in the previous studies. All the films

were found to be highly transparent in the visible wavelength region with an average

transmittance of 83 % at 550 nm. Initially with increase in core temperature from 548 to 598 K

the band gap decreases from ~3.33 to ~3.27 eV; however for further increase in core temperature

up to 648 K band gap again increases to ~3.32 eV. The photoluminescence (PL) studies on these

films showed UV/ Violet photoluminescence (PL) band.

Abstract:

Holography is one of the most important optical techniques which can provide distribution of

small particles in three-dimensional space. It is concerned with the formation and interpretation

of fringe patterns, which appears when a wave generated at some earlier time and stored in a

uses double exposure holographic interferometry together with simple mathematical relation,

which allows immediate finding of stress, mass deposited, stress to substrate and thickness of

thin film. It must be further noted that, fringe spacing changes with solution concentration as

well as time of deposition. The thin films are prepared using electordeposition technique. The

structural, morphological and surface wettability properties of the as deposited films have been

studied using X-ray diffraction (XRD), SEM and contact angle measurement, respectively.

Abstract

The effects of electron beam irradiation on the optical properties of the polypyrrole (PPy)

have been investigated. The optical conductivity and optical properties of the samples upon 7

MeV electron beam irradiation change with different doses. The irradiation doses were

conducted at 10 kGy, 30 kGy and 50 kGy. The induced changes in the optical properties for the

irradiated films were studied, in the visible range 300 nm to 800 nm at room temperature. The

optical band gap of the pristine polypyrrole was found to be 2.19 eV and it decreases up to 1.97

eV for 50 kGy dose of 7 MeV electron beam. The refractive index dispersion of the samples

obeys single oscillator model. The obtained results suggest that electron beam irradiation

changes optical conductivity and optical parameters of the Ppy thin films.

Abstract

Lowering the operating temperature to an intermediate temperature of 500–800 °C is the

main challenge in current SOFC research activities. Therefore in the present research anode-

supported solid oxide fuel cells (SOFC) based on gadolinia-doped ceria (GDC) as electrolyte, is

developed. The NiO-GDC nanocomposite is used as anode and LSCF-GDC nanocomposite as

cathode. In this particular study attempt has been made to synthesize GDC thin films on NiO-

GDC nanocomposite anode by using Spray Pyrolysis Technique (SPT). After confirmation of

phase formation of GDC thin films, the cell NiO-GDC/GDC/LSCF-GDC was characterized by

electrochemical impedance spectroscopy (EIS). Since a fundamental understanding of diffusion

phenomena and reaction mechanisms is necessary for SOFC technology and EIS should be

extremely useful in this effort. Recently, specific applications of EIS in SOFCs have appeared

frequently in the literature, and the results obtained demonstrate that this technique is an

effective approach for performance optimization and failure mode diagnosis.

Abstract

Our aim is to develop a Polyaniline (PANI) based electrode for electrochemical

supercapacitor which possesses all the characteristics needed for the superior performance of

supercapacitor. The excellent electrode required for the supercapacitor consists of good

electronic conductivity, electrochemical stability and high surface area. Taking into account the

above mentioned parameters influencing the performance of Electrochemical supercapacitor we

attempted to improve the electronic conductivity, surface area and electrochemical stability of

the PANI based electrode and hence its supercapacitive behavior.

The aim of the present study concerns with the synthesis of PANI based films using

simple and economical chemical route. The PANI, Ag-PANI, AC/PANI and Ag-AC/PANI

prepared by chemical polymerization via dip coating technique to examine supercapacitive

properties. For electrochemical supercapacitor specific capacitance and electrochemical stability

are the two important parameters for all the types of supercapacitor electrode materials

investigated in this work. But it is found that both the specific capacitance and electrochemical

stability values are better for Ag-AC/PANI electrodes due to the synergic effect of PANI, silver

and activated carbon. The highest specific capacitance of 567 Fg-1

is observed for the Ag-

AC/PANI film at 5 mVSec-1

Abstract

We have successfully synthesized graphene/MnO2 composite by simple co-precipitation

MnO2/graphene nanocomposite consist of a uniform coating of urchin-like MnO2 on the

graphene nanosheet using SEM and TEM; this structure is promising for supercapacitor

applications. Further, graphene/MnO2 composite demonstrates excellent surface properties like

uniform surface morphology, high surface area etc. Electrochemical analysis shows that

MnO2/graphene nanocomposite exhibits high specific capacitance of 476 Fg-1

in Na2SO4

electrolyte with 89 % capacity retention after 2000 cycles. The Ragone plot discovers excellent

power and energy densities of graphene/MnO2 nanocomposite sample. Such high-performance

capacitive behavior indicates that MnO2/graphene nanocomposite is promising electrode

materials for the fabrication of supercapacitors. These encouraging results promote interest in

developing such devices, including non-toxic and greener components, compared with current

Abstract

Semiconducting nanocrystals that have attracted widespread attention owing to their

distinct optical and electronic properties that can be tuned by the quantum size effect and surface

chemistry. Nanometer-size inorganic dots, tubes and wires exhibit a wide range of electrical and

optical properties which rely sensitively on both size and shape and are of both fundamental and

technological interest.

Cadmium selenide (CdSe) is the most important group II-VI semiconductor with a direct

band gap of 1.74 eV and Exciton Bohr radius 8 nm. Due to Quantum size effects, the band gap of

CdSe nanocrystals increases as their size decreases, and thus the emission colour of the band-

edge absorbance of the nanocrystals shifts continuously from red to blue as the size of

nanocrystals decreases. Here we demonstrate the growth of CdSe thin films by simple and cost

effective hydrothermal technique. CdSe thin films have been synthesized by a hydrothermal

method in which 0.1 M CdSO4 was used as cadmium precursor while 0.1 M Na2SeSO3 served as

Selenium precursor; Nitrilotriacetic (NTA) (0.1 M) acid is used as complexing agent. The

crystalline structure, morphological features, optical band gap and defect states of the resulting

samples are investigated by means of X-ray powder diffraction (XRD), Scanning Electron

Microscopy, optical absorbance and Photoluminescence spectroscopy. Photoactivity of the

samples wherein the J–V characteristics of the films were recorded using a solar simlator with a

Abstract

Lead selenide (PbSe) IV-VI group semiconductor material have attracted much more

attention in recent years due to its unique size and shape-dependent properties. The bulk PbSe

semiconductor has a rock salt crystal structure and a narrow direct band gap 0.28 eV at 300 K.

Also, the PbSe semiconductor possesses a large exciton Bohr radius 46 nm which creates strong

quantum confinement in colloidal nanocrystals and allows their band gap and absorption edge to

be tuned across the entire visible spectrum so lead selenide have been used as sensors for

infrared radiations, phototransistors, lasers, solar cells, optoelectronic devices and thermoelectric

devices compounds by different methods such as vacuum deposition, electrodeposition,

molecular beam epitaxy, chemical bath deposition and microwave-assisted synthesis have been

developed to fabricate various nanomaterials. Among them, the hydrothermal method provides a

more promising way for the synthesis of crystals due to its low cost, high efficiency and potential

for large-scale production.

Herein, PbSe thin films were successfully deposited by hydrothermal deposition method.

Structural, morphological, optical, photoluminescence and I-V characteristics of the films were

carried out with the help of X-ray diffraction (XRD), scanning electron microscope (SEM),

optical absorbance/transmittance, photoluminescence and PEC. XRD patterns of PbSe films

show crystalline nature. The optical absorbance generally reduced with increase in wavelength.

Abstract

Ceramics can play a remarkable role in the engineering of intermediate temperature solid

oxide fuel cells (IT-SOFCs) capable of meeting the ambitious targets of reduced cost and

improved life time. While mixed (ionic–electronic) conductors such as LaxSr1-xCoyFe1-yO3-δ are

adequate microstructures are also an important requirement for optimal performance, particularly

at lower operating temperatures. This Work is devoted to the fabrication of as

Abstract:

The amorphous MnO2 thin films were prepared by simple and inexpensive successive

ionic layer adsorption and reaction (SILAR) method. The prepared thin films were characterized

by means of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and

scanning electron microscopy (SEM).The electrochemical study was carried out by cyclic

voltammetry in 1 M Na2SO4 electrolyte. The films showed the maximum specific capacitance of

243 F.g-1

at the scan rate of 10 mV.s-1

. It is observed that two distinct peaks occurs in cyclic

voltammogram during charging and discharging which correspond to the electrochemical

oxidation and reduction reaction and different oxidation states of the Mn as Mn2+

and Mn3+.

Further, the increase in specific capacitance is observed with the increase in the precursor

concentration.

Keyword: MnO2, SILAR, supercapacitor.

Abstract

This study is part of effort to develop new coupling method by using photoelectrocatalyst

ZnO and microbial agent (consortium GG-BL) for the treatment of textile azo dye to produce

reusable water by the decolorization of Methyl Red into less toxic metabolites. Individually

microbial consortium GG-BL and photocatalyst ZnO showed 100% and 70% decolorization of

Methyl Red (250 ppm) with 70 and 16% reduction of chemical oxygen demand (COD) within 6

h respectively, whereas in combination of these two methods time was reduced to 4 h for 100%

decolorization of Methyl Red with significant reduction in chemical oxygen demand. Microbial

consortium showed induction in the activities of azo reductase, laccase and veratryl alcohol

oxidase during decolorization suggest their role in decolorization process. The degradation of

Methyl Red into different metabolites by ZnO, microbial consortium GG-BL and their coupled

photo-microbial system was confirmed by High Performance Thin Layer Chromatography

(HPTLC), High Performance liquid chromatography (HPLC), Fourier Transform Infrared

Spectroscopy (FTIR) and Gas Chromatography Mass Spectroscopy (GC-MS). Phytotoxicity

studies revealed the less toxic nature of metabolites formed after degradation as compared with

control dye Methyl Red.

Keywords: Photo-microbial system, ZnO, Decolorization, Methyl Red, Azo reductase, COD.

Abstract

The shift from the era of chemism to the era of environmentalism there is ample array of

heterocyclic compounds in the field of chemical, medicinal, biological and few of them

investigated for crystal structure. Chemist is found to be busy for the greener synthesis and to

maintain cost/benefit ratio, only some of them searched the applications for what they created.

Some what we diverted our ongoing study not only on synthesis but also including applications

of the synthesized moieties. Crystal Structure probe has been widely used in the field of

biological and chemical science. Our continuous efforts in the investigation of synthetic

methodology and search for potent biological moiety make curious us for its assorted

applications. (2Z)-3-(2,4-dichlorophenyl)-3-hydroxy-N-Phenylprop-2-enethioamide was

prepaired by reported procedure and investigated for its crystal structure analysis. In comparison

with the vital role of heterocyclic moieties in today’s Synthetic chemistry, numerous of

heterocyclic candidate compounds are awfully less explored to crystal structure probe.

Abstract:

In present work we report a high contrast complementary electrochromic device (CEDs)

based on nanoparticulate WO3 film as cathodically colored active electrochromic layer, Li+ as

ion conducting layer and chemically bath deposited nanoporous NiO as a anodically colored

counter electrochromic layer. The CEDs made up of WO3/NiO having size 5x5 cm2 showed

highest photopic transmittance modulation of 89.57 % at 555 nm, photopic contrast ratio of

15.68, response times of 4.39/3.7 s in its colored/bleached state and relative luminous difference

of 88 %. In addition to the improvement in the aforementioned parameters, the electrochromic

coloration efficiency of ECDs was found to be 115 cm2/C.

Abstract

PANI powder synthesized in aqueous medium by oxidation polymerization and we

present here ambient air ageing effect on vacuum evaporated polyaniline (PANI) thin film. The

effect of ambient air ageing (30 days at room temperature) on film was studied by checking

optical, mechanical and optical waveguide transmission loss properties The vapor chopping

technique was successfully used for improving film properties as well as reducing the ambient

air ageing effect. The vapor chopped film was observed with low optical transmission loss,

refractive index, intrinsic stress and high adhesion as compared to as deposited film. The air

ageing was caused to increase in refractive index, optical transmission loss and decrease in

adhesion and intrinsic stress but that effect was found to be negligible in vapor chopped PANI

thin film. Low ageing effect on optical transmission loss was observed in vapor chopped film as

compared to non-chopped film.

Abstract

Atmospheric aerosols are the suspension of colloidal particles in air. Aerosol

measurements have been carried out by using Semiautomatic Twilight Photometer, which is

capable of giving the qualitative picture of aerosol vertical distribution from about 6 km to a

maximum of 350 km. The results acquired from the Comparison between the aerosol number

density per cubic centimeter (AND) over Kolhapur and different locations of coastal area reveal

that in the troposphere, from 6 Km to 10 Km there was considerable difference for AND values

at different locations. From 11 Km to 13 Km, there was very small variation, where as no

discrepancy was observed from 14 Km to 17 Km. Again at Junge layer (~20 km) some

deviations were observed. In stratosphere and mesosphere AND was the same for all the

locations.

Another way to study the comparison is, to calculate the aerosol loading (Q) for different

intervals of altitudes. The ‘Q’ for middle troposphere (from 6 to 10 Km) is very large for

Kolhapur, comparatively smaller for locations at sea showers viz., Ganpatipule, Terekhol and

Harmal beach, and low for Sawantwadi. In Kolhapur both natural and anthropogenic aerosols are

present, whereas at sea showers only natural aerosols enriched with sea salt are present. But in

Sawantwadi, both natural and anthropogenic aerosols are present with small quantity. In upper

troposphere (from 11 to 16 Km), difference between ‘Q’ at sea showers and Sawantwadi was

very small, however Kolhapur showed larger values of ‘Q’. In case of lower stratosphere (from

17 to 30 Km), ‘Q’ values were different because AND at Junge layer was different for various

locations.

From all of these observations it was concluded that AND is different at troposphere and

Junge layer for different locations within aerial distance ~200 Km; however no any considerable

difference at stratospheric and above levels.
