Transflective and highly conductive Ag/ITO/Ag multilayer films were prepared by magnetron sputtering on glass substrates. The microstructure and optical properties of Ag/ITO/Ag multilayer films were systematically investigated by X-ray diffraction, scanning electron microscopy, and ultraviolet-visible spectroscopy. The optical properties of the multilayer films were significantly influenced by ...

Sulfur accelerates coarsening of Ag nanoislands on Ag(100) at 300 K, and this effect is enhanced with increasing sulfur coverage over a range spanning a few hundredths of a monolayer, to nearly 0.25 monolayers. We propose that acceleration of coarsening in this system is tied to the formation of AgS(2) clusters primarily at step edges. These clusters can transport Ag more efficiently than can A...

Introduction: The now extinct radionuclide Pd decays to Ag with a half life of 6.5Myr. Highly volatile element depleted (i.e. high Pd/Ag) Group IVA iron meteorites show good correlations between excess Ag and Pd/Ag. This strongly indicates the presence of live Pd at the start of the solar system [1]. Pd is both more refractory and more siderophile than Ag. Hence condensation/evaporation process...

Scanning tunneling microscopy shows that large two-dimensional Ag clusters on Ag(100) can diffuse. The value of the diffusion coefficient at room temperature is of order 10-17 cm2s-1 and varies little, if at all, with cluster size in the range studied, 100 to 720 atoms per cluster. This weak variation rules out periphery diffusion as the main mechanism of cluster diffusion, suggesting instead t...

Silver (Ag) is one of the seven metals of antiquity and an important engineering material in the electronic, medical, and chemical industries because of its unique noble and catalytic properties. Ag thin films are extensively used in modern electronics primarily because of their oxidation-resistance. Here we report a novel phenomenon of Ag nano-volcanic eruption that is caused by interactions b...

studies on biomedical applications of nanoparticles are growing with a rapid pace. in medicine, nanoparticles may be the solution for multi-drug-resistance which is still a major drawback in chemotherapy of cancer. in the present study, we investigated the potential cytotoxic effect of silver nanoparticles (ag nps) and silver ions (ag+) in both parent and tamoxifen-resistant t47d cells in prese...

A simple, fast, and cost-effective method to fabricate conductive paths on insulating Ag-containing polyamide 6 (PA6) composites by laser beam treatment is presented in this study. First, Ag-hybrid microparticles (Ag-MP) with a total metal load of up 19 wt% are synthesized based reactive encapsulation strategy utilizing activated anionic polymerization ε-caprolactam solution, the presence Ag na...
