It was reported that during silicon etching, silver was subjected to have a controversial role. Some researchers debate that silver protects silicon, and, at the same time, other ones confirm that silver catalyzes silicon underneath. In this paper, we give experimental results arguing the dual role that silver has during the formation of silicon nanostructures. We give a proof that the role of ...

introduction: infection is the most common complication of burn and one of the most important causes of mortality and morbidity in burned patients. topical antibiotics have important role in prevention and treatment of infection and reduction of mortality in burned patients. increases of use of antibiotics cause microbial resistance. methods: to determine microbial resistance to three topical a...

oxidation of ethylene to ethylene oxide over silver catalyst and selenium modified catalyst has been studied by continuous flow and pulse techniques over the temperature range of 230-280 °c. the results are discussed in terms of reaction mechanisms proposed by others, rejecting mechanisms which involve peroxide formation. it has been shown that not only selectivity towards ethylene oxide produc...

objective(s): for the development of reliable, ecofriendly, less expensive process for the synthesis of silver nanoparticles and to evaluate the bactericidal, and cytotoxicity properties of silver nanoparticles synthesized from root extract of croton bonplandianum, baill. materials and methods: the synthesis of silver nanoparticles by plant part of croton bonplandianum was carried out.  the for...

We describe two reagentless methods of silver deposition for metal-enhanced fluorescence. Silver was deposited on glass positioned between two silver electrodes with a constant current in pure water. Illumination of the glass between the electrodes resulted in localized silver deposition. Alternatively, silver was deposited on an Indium Tin Oxide cathode, with a silver electrode as the anode. B...

The first silver-FOX, silver-ammonia-FOX, and silver-amine-FOX compounds were synthesized by the reactions of silver nitrate with K-FOX or guanidine-FOX in water, aqueous ammonia, and amines, respectively. The crystal structure of silver-ammonia-FOX exhibits unique covalent bonding behavior, which is supported by NBO calculations.

Nanotechnology enables development and production of novel silver-based composite materials. We used in vitro tests to demonstrate the antimicrobial activity of a silver-silica nanocomposite compared to the activities of conventional materials, such as silver nitrate and silver zeolite. A silver-silica-containing polystyrene material was manufactured and shown to possess strong antimicrobial pr...

Oxyfluoride glass-ceramics (OxGCs) are transparent materials composed by an oxide glass matrix with homogeneously distributed fluoride nanocrystals. In particular, OxGCs RE-doped lanthanide-fluoride nanocrystals of special interest for photonic applications. More than 600 publications including several review papers were indexed on Scopus related to “glass-ceramics” revealing the importance top...
