The 1 : 4 and 1 : 2 complexes of silver perrhenate and triphenylphosphine, [(Ph3P)4Ag](+) ReO4(-) and [(Ph3P)2AgReO4]2, have been prepared and their structures determined in the solid state by X-ray diffraction. The former is composed of independent ions, while in the latter the ions are aggregated into cyclic dimers. The silver centers are tetracoordinated including contact with two bridging p...

Despite the existence of a well-known set forecast and search criteria, only three gold silver epithermal deposits were discovered on territory Amguem-Kanchalan metallogenic zone, which has significant resource potential. The base enterprises developing them is extremely limited. aim study to clarify regional local conditions for localization gold-silver mineralization, forecasting searching pr...

This chapter describes the biological synthesis of anisotropic metal nanoparticles using the bacterium Actinobacter spp. The biogenic gold nanoparticles thus synthesized show triangular and hexagonal morphology with edge lengths between 0.05 μm to 2 μm. The surface topography of triangular gold particles indicated that they are ~ 9 nm thick. These flat particles show a strong absorption in the ...

In this work, we report results of calculations based on the density functional theory of different species metal-ozone, containing mercury, silver and gold. The chosen species range from small molecules and large transition-metal containing ozone with mercury, silver and gold complexes. A comparative analysis of the description of the metal-oxygen bond obtained by different methodologies is pr...

In this study, silver and gold nanospheres were produced in aqueous solution at room temperature. The morphological optical properties of the studied using scanning electron microscopy UV–visible spectroscopy. COMSOL Multiphysics software was used to investigate properties, biological equivalent circuit chemically synthesized nanospheres. Both characterized for their surface morphology properti...

In this study, we used a 30 keV argon cluster ion beam bombardment to investigate the dynamic processes during nano-ripple formation on gold surfaces. Atomic force microscope analysis shows that the gold surface has maximum roughness at an incident angle of 60° from the surface normal; moreover, at this angle, and for an applied fluence of 3 × 1016 clusters/cm², the aspect ratio of the nano-rip...

Silver nanostructures deposited on glass showed luminescent blinking when excited at a high 442 nm irradiance. The irradiance required to photoactivate the silver, was dependent on the nature of the silver nanostructures. Silver fractal-like structures were found to be highly emissive, requiring only ≈30 W/cm(2) for photoactivation as compared to silver island films and spin-coated silver collo...

We correlate the localization of silver nanoparticles inside cells with respect to the cellular architecture with the molecular information in the vicinity of the particle surface by combining nanoscale 3D cryo-soft X-ray tomography (cryo-SXT) with surface-enhanced Raman scattering (SERS). The interaction of the silver nanoparticle surface with small molecules and biopolymers was monitored by S...

Nano particles have a wide range of applications such as electronics, catalysis, chemistry energy and medicine and have thus gained commercial acceptance [1]. Besides improving their functionality, the use of nano technology can result in the production of textiles with completely novel properties or the combination of various functions [2]. Such multifunctional textiles include antistatic text...
