Nanocomposites are an important materials class, which strives to foster synergistic effects from the intimate mixture of two vastly different materials. Inorganic nanoparticles decorated with polymer ligands, for instance, aim to combine the processing flexibility of polymers with the mechanical robustness of solid state materials. The fabrication and purification of such composite nanoparticl...

A polyvinylpyrrolidone (PVP)/Ag nanocomposite was prepared by reduction of silver nitrate in ethylene-glycol in the presence of a polymeric protective agent (i.e., poly (N-vinylpyrrolidone)). The size dependent color variation of this nanocolloid is a clear indication of the presence of Ag as nanoparticles in the polymer matrix. The nonlinear optical properties were studied by Z-scan technique ...

Biomaterials releasing silver (Ag) are of interest because of their ability to inhibit pathogenic bacteria including antibiotic-resistant strains. In order to investigate the potential of nanometre-thick Ag polymer (Ag/amino-hydrocarbon) nanocomposite plasma coatings, we studied a comprehensive range of factors such as the plasma deposition process and Ag cation release as well as the antibacte...

BACKGROUND Increased concern for potential health and environmental impacts of chemicals, including nanomaterials, in consumer products is driving demand for greater transparency regarding potential risks. Chemical hazard assessment is a powerful tool to inform product design, development and procurement and has been integrated into alternative assessment frameworks. The extent to which assessm...

Advances in friction materials are imposed on developing multiceramic reinforced hybrid nanocomposites with superior tribomechanical properties. The silver-based matrix metals gained significance various applications like bearing, ratchet, and electrical contacts due to their high frictional resistance good thermal chemical stability compared traditional metals. present research is develop cont...
