PREFACE

Scientific research performed in our Institute in 2008 was aimed at studying chemical problems of two main fields: materials as

well as environmental science.

The goal of the materials chemistry studies was to gain knowledge about selected new materials in order to assist in their scientific cognition, their evolution and to develop their production methods. For this purpose, the details of chemical composition, structure, macroscopic properties and preparation methods of some structural and functional materials, as models, were studied. Special attention was paid to nanosized and nanostructured materials.

In environmental chemistry our results concerning the principles of chemistry as well as the processes and technologies we developed, help reducing the environmental impact both during production and utilization of materials as well as in production and consumption of energy. Research is especially important in this field, because processes involving man-made materials that take place in a natural environment are based mainly on chemical reactions. As a consequence, chemical knowledge and technologies play a mayor role.

Both research fields are interdisciplinary and are integrated from the point of view of both the studied objects and the applied methods. Synthesis and investigation of various materials systems are very important elements of both fields. In many cases, the same systems were studied from the point of view of both materials chemistry and environmental chemistry. As the subjects of our studies and the methods of investigation overlap, we were able to offer a multidirectional treatment of materials and environmental issues.

Our yearbook informs you about the events and the achieved results of our Institute in 2008. I hope, this report will meet your interest.

4 RESEARCH ACTIVITIES IN 2008

4.1 Research in materials chemistry

4.1.1 Synthesis and characterisation of nanolayers

Imre Bertóti, Klára Kereszturi*, Miklós Mohai, András Tóth

In the framework of investigations aimed at improving the tribological properties of engineering polymers, the surface of polyethylene terephthalate (PET) was treated by plasma immersion ion implantation (PIII or PI3) in nitrogen. According to XPS studies, the incorporation of nitrogen and decrease of surface O/C ratio took place. The bulk plasmon loss energy of the C 1s peak increased, implying compaction of the surface layer. Topographic and nanoindentation studies showed the increase of mean surface roughness and hardness (H), and decrease of elastic modulus (E). Process conditions were found, under which a fourfold increase was obtained in the abrasive wear resistance, as determined by multiple nanoscratch measurements. The improvement in wear resistance was accompanied by the increase in the H/E ratio.

The surface of polytetrafluoroethylene (PTFE) was modified by saddle field fast atom beam (FAB) source. According to XPS results, upon FAB-treatment the surface F/C value decreased strongly. The small-scale wear resistance improved, the mean surface roughness increased and the water contact-angle decreased upon FAB-treatment.

A new version of the XPS MultiQuant program, developed previously in our laboratory for the quantitative evaluation of X-ray photoelectron spectra, was released. Geometry parameters of small polyhedra can now be given, which allows modelling of rough surfaces and more precise determination of thickness values of layers present on rough surfaces

like those of microcrystalline or granular materials or striated specimens. The applicability of the new model and program was tested on geometrically structured silicon and aluminium samples.

4.1.2 Deposition of simple and composite ceramic coatings

Cecília Bartha*, Zoltán Károly, Anna Mária Keszler*, Szilvia Klébert, Ilona Mohai, János Szépvölgyi

The aim of our research is to prepare coatings of good mechanical and tribiological properties on metallic and nonmetallic substrates by atmospheric plasma spraying. The coatings consist of single or multi component ceramics, or nanocomposite based ceramic structures. This method results in the improvement of the mechanical and chemical properties of the coated construction materials (eg. excellent wear and corrosion resistance, hardness, thermal shock resistance etc.)

Novelties of our work are the followings: Precursor powders, composites and nanocomposites are prepared by ourselves. These ■powders are not available on the market

The special additive powders, such as semiconductor SiC granules and ferrites with ■high Curie point, are synthesized in our RF thermal plasma system

The spraying of non oxide ceramic powders (eg. SiC and Si ■ 3N4), that rather decompose instead of melt at high temperatures, were also studied. These ceramics are jointly used with some oxide ceramics that help to form a molten phase

The coatings are comprehensively analysed by various (chemical and phase composition, ■structure, thickness, adhesion etc.) methods available either in our Institute or at our partners

4.1.3 Archeometry

Zoltán May, Klára Szentmihályi

Our main goal is the archaeometrical study of the provenance and production technology of old, Hungarian historical (medieval) bricks in a complex way, with the help of mo-dern analytical methods and instruments (XRF, XRD, ICP-AES, TL, CL, ESR). For this purpose, basic research must be accomplished including the chemical composition of the raw materials (trace elements of the clay minerals), firing temperatures, and reaction kinetics and mechanism during firing. On the other hand, we study the influence of these parameters on the properties of bricks, as well.

The modern bricks produced in Hungary has been widely studied and well documented in structural and chemical points of view. In contrast to this, Hungarian historical ceramics and bricks were processed only according to their main style parameters. Only a few sporadic results can be found from material sciences point of view. For this reason, we aimed at collecting basic data about the history of technology and methodology of brick making, using state-of-the-art techniques on selected samples.

Furthermore we intend to create an accessible and handy database about chemical properties of these historical materials, which can be used for further archaeometrical research. Such kind of database does not exist at this moment.

In the future, we will expand our studies to the provenance and production technology of Hungarian historical ceramics and jewelries, as well.

4.1.4 Preparation, formulation and analysis of functional particulate materials

Tivadar Feczkó, Judit Tóth

In the framework of an international project, called BioPowders, it was investigated how nanostructured chitosan microspheres can be used for enzyme immobilization, and how they influence the activity of the biocatalyst. The nanostructured biocatalyst supporter was proved to be useful for biotechnological purposes.

Important results were achieved in industrial use of particulate solids, applicable for covering material of electrical elements, and in improvement of their characteristics: ferrite powders were produced with proper magnetic and morphological characteristics. The rheological properties of ceramics were meliorated by fluid granulation.

Transport processes of soil contaminants were studied. The particle size distribution of soil samples, mainly determining their behavior, was investigated by laser diffraction analyzer. Composites of chitosan carrier material were prepared with protein type drug by mechanically spouted bed dryer.

4.1.5 Synthesis and examination of permanganates and polygalacturonates

Judit Fodor*, László Kótai, Zoltán May, Klára Szentmihályi

Tetraammine-zinc(II)dipermanganate was prepared, and its structure was elucidated with XRD and vibrational-spectroscopic methods. It has been stated that the compound has a cubic lattice consisting of a 3D H-bound network built from blocks formed by four permanganate anions and four zinc tetraammine cations.

The structure and the presence of certain microenvironments of essential metal complexes bounded to polygalacturonic acid were studied. The examination of iron-polygalacturonate was highlighted because iron is known for a long time as the most important metal ion. It is a substantial component of several enzymes, like some transfer and depository proteins, hemo-globin and myoglobin in the form of both non-heme and heme iron. According to our earlier studies it was supposed that the iron is mainly found in divalent form in the iron-polygalacturonate and it is connected to the glycosidic oxygen also with covalent bond.

Mössbauer spectroscopic studies supported the findings of the effectiveness of the Ferrocomp tablet. The agent of it, the iron-polygalacturonate has of natural origin and it contains iron in accordance with the form of iron bond in plants. Because of it the absorption and bioavailability of iron-polygalacturonate occur similarly to the form of our natural foodstuffs. Ferrocomp tablet is a product of In Vitro Kft. based on the licence of Chemical Research Center.

4.1.6 Nanostructured amphiphilic polymer conetworks and their applications

Gábor Erdődi, Csaba Fodor*, Márton Haraszti, Béla Iván, Gergely Kali*, Péter Mezey*, Sándor Szabó

Our research with amphiphilic conetworks and hydrogels aims at in part drug delivery as well as yeast cell immobilization in polymer hydrogels. Poly(N-vinylimidazole) based amphiphilic conetworks were synthesized for binding different metal ions from aqueous solutions due to the complex formation of this polymer with positively charged ions. AFM measurements confirmed nanophase separated structure of the new conetworks. The metal ion chelating of these conetworks was also studied.

The swelling behavior of the poly(metacrylic acid)-l-polyisobutylene conetworks were investigated in aqueous solutions containing Ca2+, Cu2+ and La3+ ions. We have found that in contrast to the conventional homopolymer hydrogels, these amphiphilic gels did not collapse. A new process was also developed for the synthesis of APCNs based on ethoxyethyl acrylate and ethoxyethyl methacrylate monomers. Thermoanalysis of the conetworks was carried out. Hydrolysis, thermolysis and swelling behavior were studied by IR spectroscopy.

Successful synthesis of nanosilver containing nanohybrid amphiphilic conetworks based on poly(N,N-dimethylacrylamide)-l-polyisobutylene was also investigated. Existence of silver nanoparticles was proved by TEM and UV-VIS spectrophotometry.

We have made attempts for the synthesis of new amphiphilic conetworks, which possess „intelligent”, thermo-responsive properties. As hydrophilic component, poly(N,N-diethyl acrylamide) in conjunction with hydrophobic polydimethylsiloxane and polyisobutylene were used. Such materials can be applied in a wide range of applications from biomaterials and biotechnology to sensors.

4.1.7 Synthesis of well-defined polymers with narrow polydispersity and complex architecture via quasiliving radical polymerization

Béla Iván, Amália Soltész*, Ákos Szabó*, István Szanka*, Márta Szesztay

Quasiliving radical polymerizations have been rapidly progressing in recent years. These new processes have largely extended the capabilities of polymer chemistry. The potential benefits of these new polymerization technics are related to the unique and improved physical and chemical properties of the resulting polymers. Due to these inventions, a variety of new applications have come into view. In comparison to earlier methods, quasiliving radical polymerizations have huge advantages from both economic and environmental points of view.

We developed a new synthetic method to produce hyperbranched polymers. On the basis of kinetics and mechanism of quasiliving radical polymerization, the use of commercially available monomers (styrene and (meth)acrylates) for the synthesis of hyperbranched polymers with different functional groups by one-pot reactions is possible. Our research group has the know-how to exploit quasiliving radical polymerizations in several fruitful international cooperations. For example, we have a long-term R&D cooperation with the DuPont Co.

The synthesis of well-defined block copolymers of isobutylene and poly(ethylene oxide) based macromonomers via quasiliving carbocationic/radical polymerizations was also explored. These biocompatible polymers might be of great importance in medicinal applications.

The polymers have been characterized by a gel permeation chromatography (GPC) system equipped with multi-angle light scattering (MALS) detector and 1H NMR spectroscopy.

4.1.8 Carbocationic polymerization

Gábor Erdődi, Béla Iván, György Kasza*, Viktória Pálfi, Ákos Szabó*, Márta Szesztay, Klára Verebélyi*

Our research covers studies on the mechanism of quasiliving carbocationic polymerisation and the modification, and structure related properties of the resulting novel polymers. We studied the effect of certain additives on the polymerization of isobutylene which leads to the formation of double bonds at the polymer chain end quantitatively under carbocationic circumstances.

Polyisobutylene bearing olefinic chain end was successfully functionalized by “thiol-ene” reactions. This method permits the development of various functional groups in a simple addition reaction.

Investigations on environmentally benign, “green polymer” syntheses were also carried out. We have synthesized polystyrene with different structures at room temperature without the use of chlorinated solvents, and the minimum required concentrations of additives were also determined.

Taking advantage of a side reaction, considered previously as an undesirable process, we managed the production of hyperbranched polystyrene. We have explored and verified that the branched structure is the result of an intramolecular Friedel-Crafts alkylation reaction between the carbocatonic chain end and a phenyl group along the polymer chain. The reaction conditions have been optimized in order to control the structure and properties of the hyperbranched polymers.

4.1.9 Degradation and stabilization of polyolefins

Enikő Földes, János Kovács*, Ildikó Kriston*, János Móczó, Béla Pukánszky, Károly Renner*

The effects influencing degradation and stability of polyethylene and polypropylene produced by different catalysts were studied under processing and application conditions. The role of catalyst residues and processing conditions in the characteristics of polyethylene and polypropylene were investigated. Relationships were established among the characteristics of nascent polymer powder, the composition of additive package and the chemical reactions taking place during the processing of polyethylene. It was established that the type of phosphorous antioxidants determines the reactions of polyethylene during processing in the first place.

The differences in the reaction mechanism of various phosphorous antioxidants were explored by model experiments. We concluded that the efficiency is influenced by both the reactivity and the self-thermal stability of phosphorous molecule. The effect of acid scavengers on the efficiency and consumption of antioxidants was studied in polyethylene and found to depend strongly on the composition of the complete additive package. The hydrolytic stability of antioxidants was studied in polyethylene pipes in cooperation with TVK polymer producer. The results are utilized directly in the development of additive packages for polyolefins improving the competitiveness of the products.

4.1.10 Natural and synthetic polymers and their composites

Structure-property relationships and deformation processes under loading were studied in natural and synthetic polymers, as well as in their composites. Deformation and breaking mechanism of PP/sawdust composites containing particles of different sizes were studied. The conclusion was drawn that the stiffness of the composite increases with increasing filler content, but the modulus is not influenced significantly by the type and amount of functionalized polymer used as coupling agent. The other mechanical characteristics depend strongly on the type and amount of coupling agent (maleic anhydride modified polypropylene). Coupling agents with higher molecular masses and lower functionality are favorable for obtaining higher mechanical strength and impact resistance.

Significant progress was achieved in the study of layered silicate/polymer nanocomposites produced by delamination. The structure was also investigated by rheology. The results showed that the relaxation time is increased by network structure formed as a result of exfoliation in layered silicate nanocomposites, which is well reflected in the rheological properties. Parameters describing quantitatively the changes in structure were determined by model calculations. Groups and segments in cellulose acetate and some natural polymers of similar structure were assigned to the α-, β- and γ-relaxation transitions measured by DMTA.

4.2 Research in environmental chemistry

4.2.1 Research on feedstock recycling of plastics waste

Marianne Blazsó, János Bozi*, Béla Iván, Zsuzsanna Czégény, Emma Jakab, Györgyi Szarka*, Márta Szesztay

Utilization of Y-zeolite for promoting pyrolytic recycling of polyamide 6,6 and ABS (acrylonitrile-butadiene-styrene copolymer) has been studied. It was found that the thermal decomposition of these polymers leading to environmentally dis-trustful nitrogen containing com-pounds is not altered significantly. Nevertheless, the thermal de-composition product molecules formed under pyrolysis of these polymers can be converted over zeolite. The protonic Y-zeolites are able to denitrogenate pyrolysis products, while the contaminating halogen compounds could be eliminated from the pyrolysate over Na-zeolites. Dehalogenation activity proved to be diverse for compounds of different type of halogen-carbon bond.

We have continued our research on the degradative transformation of PVC to make environmentally advantageous secondary products. The effect of zinc stearate, a widely used heat stabilizer was investigated to make the degradation and the appearence of polyene sequences in the polymer backbone

faster at the same time. This phenomenon permits a new type of transformation of PVC wastes in which the PVC containing reactive double bonds could be the starting material of secondary products.

4.2.2 Studies on the utilization of biomass materials

Erika Mészáros, Emma Jakab, Zoltán Sebestyén*, Gábor Várhegyi

A novel environmental-friendly process has been employed for bleaching wood pulps using laccase enzime and violuric acid mediator at the University of Beira, Portugal. We have applied a degradative method for the determination of the residual lignin content of the pulps using in-situ pyrolysis-gas chromatography/mass spectrometry. It was observed that the distribution of the lignin monomers changed significantly in the pyrograms of the pulps and the isolated residual lignins. It was established that the functional groups of lignin undergo similar chemical reactions during enzymatic biobleaching than during Kraft pulping.

The thermal decomposition reactions play crucial role in combustion as well as in various industrial processes, thus, we studied the thermal decomposition of biomasses that are abundantly available as by-products or are suitable for feasible production in energy plantations. The range of the samples studied in 2008 included straws, corn-stalk, sorghum, rice husk and Ethiopian mustard. Kinetic models were established that describes well the thermal decomposition of these substances at different temperature programs. Though the studied samples showed a wide variation in their composition and mineral matter content, similarities were found in the kinetics of their thermal behavior.

4.2.3 Atmospheric chemistry studies

Attila Demeter, Sándor Dóbé, Mária Farkas*, Rebeka Nádasdi*, István Szilágyi, Gábor László Zügner*

The rate constant for the elementary reaction of OH radicals with acetyl-fluoride, CH3C(O)F, and its photodissociation quantum yield (QY) have been determined. A strong negative inductive effect caused by the F-substituent was observed for the OH-reaction. The effect was quantified by deriving group-aditivity value for the FCO group. The photodissociation QY has been found significantly less than unity indicating an important role of physical quenching in the mechanism. Acetyl-fluoride is a reaction intermediate formed during the atmospheric degradation of the Freon-substitute HFC-152a (CH3CHF2). The laboratory results imply that the atmospheric lifetime of CH3C(O)F is relatively short and so its global warming potential is not significant.

The quenching rate of singlet excited acetone by O2 has been determined under atmospheric conditions. The rate constant of this spin forbidden process is comparatively small and the observed temperature dependence is in accordance with a negative activation energy.

A simple method has been proposed for the synthesis of 3,3’,5,5’-tetra-(trifluoromethyl)-benzophenone. This molecule possesses very interesting photochemical and photophysical properties with promising applications in environmental photochemistry.

4.2.4 Environmental electrochemistry

István Bakos, Gabriella Lendvay-Győrik, Gábor Mészáros, Tamás Pajkossy, Sándor Szabó

Platinum is getting progressively accumulated in the environment. Because of it a highly sensitive method for measuring platinum concentration has been developed. This method is based on deposition of ultra-low quantity of platinum on gold at potentials more positive than the equilibrium potential.

Basic electrochemical measurements – mostly cyclic voltammetry and impedance spectroscopy - have been carried out for characterizing adsorption of certain anions and to study the structure of the double layer on platinum group metals in simple aqueous binary electrolyte solutions. As it was demonstrated by impedance measurements, the exchange kinetics of anions can be characterized between outer and inner positions of the electrochemical double layer.

We have previously elaborated a method and device for the fast measurement of electric currents in the femtoampere range. This device has been improved and now it can be used for sensitive electrochemical measurements em-ploying ultramicroelectrodes and also in electrochemical scanning probe microscopes.

4.2.5 Monitoring and remediation of oil contaminated soils; Regeneration of active carbon adsorbents

Éva Fekete, Tibor Horváth, Béla Lengyel, Zsuzsa Mayer*, György Mink, Emma Jakab, Miklós Prodán, Zoltán Sándor, Péter Szabó

In the framework of an industrial contract, preliminary experiments have been carried out by geoelectric method to detect and localize underground oil impurities originating from damaged pipelines. Parallel to this, technology development has been started to mitigate harm at the contaminated areas, both by impurity fixation and by in site chemical oxidation (ISCO) methods. To characterize the pipe-transported fluids as possible contaminants, domestic crude oils and a large number of their lighter derivatives have been analysed in detail, using GC/MS, HPLC, and UV/VIS methods. Similarly, proper and reliable analytical methods were developed to determine the concentration and the composition

of the assumed contaminants, both in soil and groundwater.

Project entitled “Method and equipment for the regeneration of active carbon adsorbents used for air purification in spray painting manufactures” has been finished in 2008. As a last phase of our activity, the reference unit of 600 kg/d capacity, to be used on the spot of the workshop, was supplied with a modern process control and data acquisition system.

4.2.6 Surface coating technologies with reduced VOC emission

Éva Fekete, Béla Lengyel

Low VOC content coating systems that are built up from different solvent borne and waterborne paints and contain new, environmentally friendly pigments were investigated, and their resistance to water moisture and salt spray, as well as their lacquer technical properties were determined.

The corrosion resistance and the lacquer technical properties of coating systems built up on cast iron and zinc-phosphated steel component parts were investigated. On the basis of these investigations environmental-friendly coating systems that acceptably withstand heat and sparks have been recommended for painting the external surface of the brakes of railway carriages. By using waterborne materials cost reduction and environment protection were both achieved.

Nanomechanical and nanotribological studies ►

Two types of measurements are performed in this area:

Dynamic, depth-sensitive nanoindentation, for determining hardness and elastic ■modulus of the surface layer of materialsDynamic scratch-, wear and topographic tests, for determining resistance ■to scratch and abrasive wear, and establishing surface roughness, friction coefficient, and layer thickness

The layer thickness studied ranges between a few nm and several μm. During the dynamic test the load applied to the diamond head, and the penetration depth, are followed simultaneously.

Wettability studies ►

Static contact angle is studied by the sessile drop method and the surface free energy is calculated by various methods.

surface modification and lab-scale deposition of thin layers ►

The surfaces of polymers, ceramics, glasses, metals, composites and biomaterials ■are modified by plasmas and particle beams like glow discharge, plasma beam, fast atom beam, plasma immersion ion implantation (PIII). In particular, PIII can be used to modify uniformly, in a single step the surface of irregularly-shaped devices (nitriding, carburizing, etc.), with the aim of improving hardness, wear resistance and other properties (e.g., wettability).Lab-scale deposition of hard and corrosion resistant (nitride, carbide or carbon- ■based) coatings is performed by RF and DC magnetron sputtering or PECVD under various conditions, to achieve targeted compositions and properties.

Thermal Plasma Laboratory

Research projects of the laboratory aim at the study of the chemical reactions occuring under thermal plasma conditions. For this purpose we operate a 27 MHz / 4 kW and a 3-5 MHz / 30 kW RF plasma reactor, and transferred and non-transferred arc DC plasma systems of 40 kW power. For the characterization of the starting materials and the products the following methods are used: bulk and surface chemical composition (ICP-AES, XRF, N/O analysis, XPS), phase composition (XRD), microscopic techniques (SEM, TEM), particle size analysis (LDA), physi- and chemisorption.

A fast ■heating of the sample is followed by an isotherm pyrolysis of 10 - 30 s. The volatile pyrolysis products are analyzed on-line by gas chromatography – mass spectrometry. The conversion of the thermal decomposition products over solid catalysts is also examined

Atmospheric Chemistry Laboratory

The main research area of our group is the study of the kinetics and molecular mechanism of elementary chemical and photochemical reactions. For the most part, we investigate such processes and phenomena that play an important role in the complex interplay between climate change and the chemistry of the environment. We apply mainly laser-based experimental techniques for the production and detection of reactive species (e. g. free radicals). The kinetic and photochemical data determined experimentally are being used as input parameters in atmospheric chemistry and combustion models. Following are the main research themes:
