The development of technologies have provided the emergence of new forms for the processing of materials such as additive manufacturing techniques. For use of different materials in this type of processing, it is necessary ...

The friction phenomenon still does not have an understanding in fundamental terms. Such understanding would help clarifying the frictional energy dissipation during the interaction between atoms of two or more surfaces ...

The self-assembled films (SAF) by physical adsorption, compounds of organic polyelectrolytes and inorganic semiconductor nanoparticles are considered an inexpensive process and non-pollutant deposition that gives films ...

Austenitic stainless steel materials are widely used in systems that require high oxidation resistance and corrosion resistance. However, in contact with other surfaces, these materials show a high coefficient of friction ...

The aim of the present work is to explore the production, dispersion and consolidation of zirconia (zirconium oxide – ZrO2), in its hydrous form, obtained from zirconium tungstate (ZrW2O8) in alkaline medium using temperatures ...

Diamond-like carbon thin films (DLC) show a unique combination of properties such as high wear resistance and ultra-low friction. However, a widespread use regarding energy efficiency issues in the automobile industry is ...

The development of new technologies for the treatment of wastewater containing dyes has generated a great interest in recent years, due to increase awareness about environmental preservation, in addition to the rigidity ...

Zinc oxide nanoparticle (nano ZnO) is a kind of inorganic multifunctional filler, which has extensive uses in rubber additives. Notably, most of relevant researches about nano ZnO focused on using them as a substitute of ...

Zirconium tungstate (ZrW2O8) is a ceramic material which exhibits several unusual properties such as negative thermal expansion, amorphization induced by high pressures ( 1.5 GPa and 2.0 GPa) and endothermic recrystallization ...

In this work, was investigated the obtaining of new materials from the hydrolysis and acid condensation reactions of (3-aminopropyl) trimethoxysilane, which resulted in the formation of hybrid nanostructures with ammoniums ...
