For a green world…

NanoTechnologyIn 1959 the American physicist Richard Feynman gave a talk considering the possibility of manipulating single atoms to build new systems.

This is considered the beginning of nanotechnology.

Nanotechnology is the science of materials of phenomena in the range of 1 to 100 nm of diameter. A nanometer is a billionth of a meter or a millionth of a millimeter.

Nanomaterials can have unique and innovative properties and they can be exploited to create new materials and devices which might resolve some of the main problems of the world.

Nanotechnology finds applications in very diverse fields such as medicine, organic chemistry or materials science which is the field of 4Ward360.

Scientists and engineers nowadays are discovering new ways to manipulate these materials at the nanometer scale and take advantages of their properties. Actually, materials at the nanoscale have been used also in the past by artists and craftsmen.

For instance, gold and silver nanoparticles produce colors when dispersed in glass, as in the case of windows in the Medieval cathedrals or the Lycurgus cup.

Another example is the production of a pigment known as “Maya blue”, a mix of clay and colorants that creates a unique and bright blue tonality.

NANOTECHNOLOGY PROTECTIONfor all kind of glass such as: photovoltaic panels, glass building, shower cubicles, car glass and much more

The origins of glass are as old as our planet. Prehistoric men already utilized a glass present in nature: obsidian (volcanic glass), to make knives, arrowheads and other useful tools.Despite its ancient origins, glass is a modern material. Highly technological, functional and elegant. It fulfills the requirements of designers and contemporaneous users. In building industry, glass is considered a privileged material due to its hardness and transparency characteristics that allows a direct contact with the external environment while protecting us from it.

Thanks to technological progress and continuous research, glass production today is highly specialized being possible the preparation of thinner and thicker glasses. In this way new transformed products have emerged such as tempered, laminated, isolating, coated or printed glass. Although glass is very resistant to degradation, it undergoes environmental aggressions that cause changes such as brightness loss or the formation of iridescent or opaque layers with a color sometimes different from the original one. The factor playing a main role in degradation is linked to water in its different forms: acid or basic solutions in the ground or in the sea, aqueous vapor, etc.

Smog, thin dust, pollution and limestone may shatter the natural elegance and transparency of glass. The costs related to cleaning and maintenance are high with disappointing results on the appearance and duration.

4Ward360 efficient and innovative nano-formulation, based on silicon dioxide, has been specifically developed for tempered, isolation and sound-proof glasses, photovoltaic panels, greenhouses, glazed walls, glass buildings and showers.

The protective formulation has the ability of “merging” with the glass surface at the molecular level, modifying its energy and providing a durable and resistant protection over time. The higher the surface energy the higher the pollution caused by limestone, dust and dirt.

Our formulation decreases dramatically the surface energy of glass from 1000 mN down to 18 mN, repelling pollutants. In this way they slip away or can be easily removed without the use of detergents or abrasive means.

The treated surfaces become repulsive to water, dirt, limestone, resistant to ice (-35°C), high temperatures (450°C) and high pressure (in the case of vapor cleaning).

Therefore the treatment provides added value to glass without neglecting the ecological aspect.

Characteristics

– Excellent hydro and oil repellent properties

– Invisible: it does not change the appearance of the glass.

– Durable over time

– Resistant to high and low temperatures

– Stable to UV radiation

– Anticorrosive

NANOTECHNOLOGY PROTECTIONporous walls and floors

Buildings and properties of new generation present innumerable problems nowadays related to humidity accentuated during the last years due to increasing atmospheric pollution phenomena.The repercussions of pollution on buildings appear mainly as erosion, friability of the materials, blackening (fouling) and biological pollution (moss, molds).The main natural degradation factors are water, temperature variations, electromagnetic radiations and atmospheric gases.Water can contribute to degradation processes in its different forms (liquid, solid and gas). Its particular characteristics are determined by the “polarity” of its molecules (negative poles on the oxygen and positive poles on the hydrogen). This is the reason why materials with polar structure draw water inside (hydrophilic materials). This occurs for example in porous building materials (stone, bricks, mortar), that draw water inside the fine pores (capillaries) triggering degradation processes at low temperature by the formation of ice and at medium-high temperature as water evaporates leaving back soluble salts.Water in liquid form can get in contact with the surface of the materials not only under the form of rain but also by means of moisture condensation phenomena (dew) that transport many of the solid and gaseous impurities present in the atmosphere.The presence of water leads also to microbiological degradation.The high humidity content of air and the periodic availability of water (rain) in a certain temperature range make possible the development of microorganisms colonies (algae, fungi, lichens, bacteria).



These problems are a real challenge to workers in this field. Challenges that can however be overcome, thanks to 4Ward360.Our nanotechnology protective treatment does not alter the characteristics of the object nor the aspect nor the breathability and protects from degradation by means of innovative and non-invasive techniques.

NANOTECHNOLOGY PROTECTIONarcheological materials and fine arts

The world of stone has always been fascinating and full of history. From the Stone Age when everything was created with this material, to the Egyptian pyramids, the Aztecs, the Roman temples, etc. In this way marble, granite and tuff took life to be transformed in the enormous cultural patrimony that makes Italy a unique country in the world.Unfortunately during the last years degradation of this overwhelming patrimony has been enormously accelerated due to the increasing pollution phenomena. Paradoxically it has been shown that the degradation rate has been higher during the last 50 years than in the previous centuries. Works that have displayed their magnificence over time show in the last years an evident degradation. Finding a solution to defend these precious goods from environmental degradation by atmospheric agents aggression, acid rain, fungi or dirt becomes a primarily need.During the last decades in order to confer protection and consolidation, polymers such as

acrylic or vinylic resins have been used. But contrarily to the expectations they have caused further damages.The main degradation factors of natural origin are water, temperature changes, electromagnetic

radiations and atmospheric gases.Water: it can contribute to degradation processes in both liquid, solid or vapor state.Pollutant gases: which are present in the atmosphere.Thermal oscillations: the increase in the dimensions that all the materials undergo when heated (thermal dilatation)Atmospheric gases: oxygen in the presence of the adequate synergies (visible and ultraviolet radiation, water, catalysts such as metal oxides) causes oxidation processes of organic materials.Human activity often determines the right conditions for the development of degradation processes. What is more, it is one of the most important factors.



The contribution of our nanotechnology protective products to the world of fine arts is unimaginable. More specifically our products have the ability of modifying the surface energy from high to low, creating a 3D network with a repulsive force that repels any pollutant and blocks every form of degradation. All without modifying the aspect of the work or its breathability.

The term “natural stone” makes reference to marble, granite and other rocks used for sculptures and architecture.By “artificial stone” we make reference to materials obtained by the elaboration of natural stone to produce plasters, coatings, stucco, ceramics, mortars, etc.Both types of materials (natural and artificial) undergo degradation phenomena that can be explained by factors such as:DIFFERENCES IN THE CHEMICAL AND MINERALOGICAL COMPOSITIONS AND PHYSICAL AND STRUCTURAL DIFFERENCES IN THE MATERIALThe degree of absorption of water and its mobility inside the material depends on its porosity. Closed pores do not communicate between them and do not allow the water to circulate. They do not participate in capillary absorption phenomena but undergo other degradation processes. Open pores (mortar, tuff, bricks, limestone) conversely intercommunicate by capillaries that favor the circulation of water. The higher the porosity the higher the ability to absorb water.The phenomenon is increased by the presence of salts due to their high hygroscopicity.MICROCLIMATIC CONDITIONS Temperature, air moisture, ventilation, rain Degree of exposure to atmospheric agents Type of processing of stone materials.The main vehicle for the degradation of stone materials is water under the form of rain,

condensation, capillary moisture or losses from waterworks. The degradation can be under the form of:Losses of material (chipping, erosion, pitting)Decrease in the cohesion of the material (disintegration, pulverization)Loss of continuity (fracturing, cracking, parting)Adhesion of alien material (efflorescences, crusts, concretions, surface depositions, stains)Change of color (chromatic alteration, films)Presence of micro and macroflora (presence of vegetation, biologic films)The presence of environmental contaminants contributes furthermore to increase and

accelerate the phenomena of degradation.



Our nanotechnology formulations (based on SiO2) are indicated to protect efficiently all the compact, porous and bright surfaces such as marble, granite, stoneware, etc.A revolutionary nanotechnology treatment anti-dirt and anti-abrasion that repels water and dirt particles preventing their adhesion to the surface. Thanks to its hydro and oleo-repellent properties, grease, limestone and other contaminants do not penetrate inside the substrate of the treated surface and are easily eliminated without abrasive means.Our formulation has the ability of penetrating inside the micropores protecting them from abrasion. The treatment does not modify the breathability of the surface.
