Nanowires (NW) are defined here as metallic or semiconducting particles having a high aspect ratio, with cross-sectional diameters « 1 ┤m, and lengths as long as tens of microns. Well-aligned one-dimensional nanowire arrays have been widely investigated as photoelectrodes for solar energy conversion because they provide direct electrical pathways ensuring the rapid collection of carriers genera...

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...

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 optical properties of core-shell nanoparticles consisting of a ZnO shell grown on Ag and Au nanoparticle cores by a solution method have been investigated. Both the ZnO/Ag and ZnO/Au particles exhibit strongly enhanced near-band-edge UV emission from the ZnO when excited at 325 nm. Furthermore, the UV intensity increases with the metal nanoparticle concentration, with 60-fold and 17-fold en...

Microscopes typically collect light over large ranges of angles dispersing plasmonic resonances. While this is an advantage for recording spectra of microscopic particles, it is a disadvantage for sensing by resonance shifts. Adaptations are described herein which enable one to identify, manipulate, and examine narrow plasmonic resonances under a microscope. Noting more general familiarity with...

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...

Nanoparticle alloys of platinum (Pt) and another metal are desirable for catalytic applications to decrease the loading of the precious metal and alter the physiochemical structure of these materials to enhance their catalytic properties. This study explores the potential of producing gold and platinum nanoparticle alloys using a microplasma reduction technique. In this process, metal salt prec...

Abstract I analyze theoretically the spatio-temporal kinetics of reduction oxidized metal nanoparticles by hydrogen (or methane). The focus is on experimentally observed formation and oxide domains separated partly pores. interpretation such multiphase processes in at mean-field level hardly possible primarily due to complex geometry, accordingly use lattice Monte Carlo technique order tackle t...
