Computational studies have attracted the attention of researchers to understand the structural behavior of the molecules. These methods grade complex systems for novel properties with new predictions in areas of physics, chemistry and biology useful for conduct of experimental studies. Nanoparticles in present day technologies have become integral part in diverse areas of science mostly with me...

The purpose of this study was to investigate the difference between tungsten inert gas (TIG) welding of austenitic stainless steel assisted by microparticle oxides and that assisted by nanoparticle oxides. SiO₂ and Al₂O₃ were used to investigate the effects of the thermal stability and the particle size of the activated compounds on the surface appearance, geometric shape, angular distortion, d...

Heteropoly acid promoted nanoparticle of nickel oxide samples were prepared by sol-gel method using heteropoly acids. Prepared composite was characterized by XRD, FT-IR and ICP technique. In this work, we have reported bromination of phenol, its derivatives and some aromatic compounds. The liquid phase bromination of phenol was Performed using heteropoly acids immobilized nanoparticle of nickel...

In the present work, we introduce a facile and reliable approach to decorate TiO2 nanotubes homogenously with wellseparated copper oxide nanoparticles. For this, we use a palladium-containing titanium alloy (commercial Ti 0.2 atom% Pd) and grow anodic, self-organized oxide nanotubes. Palladium is embedded in the tube wall during growth and acts as activator for a subsequent electroless copper-n...

Ultra-violet protection and self-cleaning action of nano zinc oxide (ZnO) and titanium di-oxide (TiO2) with acrylic binder has been assessed on the cotton fabric using pad-dry-cure method. Different precursors, such as zinc acetate and titanium tetrachloride have been used to synthesize nanoparticles. Zinc acetate is synthesized into nanoparticle by wet chemical technique and titanium tetrachlo...

The molecular responses of macrophages to copper-based nanoparticles have been investigated via a combination of proteomic and biochemical approaches, using the RAW264.7 cell line as a model. Both metallic copper and copper oxide nanoparticles have been tested, with copper ion and zirconium oxide nanoparticles used as controls. Proteomic analysis highlighted changes in proteins implicated in ox...

Dual phase (a þ b) copper–tin alloys were synthesized from elemental nanoparticle precursors following consolidation, annealing and quenching steps. The precursors were derived from the sequential reduction of tin and copper salts in ethanolic solution. The dual phase microstructure exhibits a duplex character with a mixture of Cu-rich and Sn-rich (a þ b) regions. 2004 Published by Elsevier Ltd...

We review a self-assembled growth method for plasmonic nanoparticle arrays, based on glancing angle deposition. We produced ordered Ag, Au, and Cu nanoparticle arrays over large areas on different stepped oxide templates. Precise control over the final geometry can be difficult and we provide recipes to obtain macroscopically ordered structures. We discuss the influence of the adsorbate diffusi...

Human immunodeficiency virus type 1 (HIV-1) can be transmitted through breast-feeding and through contaminated blood donations. Copper has potent biocidal properties and has been found to inactivate HIV-1 infectivity. The objective of this study was to determine the capacity of copper-based filters to inactivate HIV-1 in culture media. Medium spiked with high titers of HIV-1 was exposed to copp...
