silver has been known and used as a potent antimicrobial and wound healing agent since ancient time. silver compounds have had other ancient applications through which greeks, romans and egyptians had used silver compounds as food and water preservative. silver and silver-based antimicrobials were put away after the discovery of antibiotics. meanwhile, with almost a century application of antib...

in this research, synthesis and characterization of silver/alumina composite powders was investigated. this kind of metal/ceramic composite powders is used for fabrication of cutting tools inserts. the role of silver is toughening the final product. the powders were synthesized via co-precipitation method. the composition of the synthesized powders was ag/80% wt 〖al〗_2 o_3. silver nitrate, alum...

While several databases with Raman spectra of interest to silver corrosion have been published already, we present a catalogue of Raman spectra of silver compounds, which can be found on corroded silver and silver alloy objects, i.e. not only concerning archaeological and artistic works but all kind of silver items exposed to the atmosphere. The collected Raman spectra of these highly pure (>99...

New cationic silver-containing ionic liquids were synthesized and used as non-aqueous electrolytes for the electrodeposition of silver layers. In the liquid state of these ionic liquids, a silver (i) cation is coordinated by pyridine-N-oxide (py-O) ligands in a 1 : 3 metal-to-ligand ratio, although in some cases a different stoichiometry of the silver center crystallized out. As anions, bis(tri...

Silver compounds share a rich history in technical applications including photography, catalysis, photocatalysis, cloud seeding and as antimicrobial agents. Here we present a class of silver compounds (Ag2B10H10 and Ag2B12H12) that are semiconductors with a bandgap at 2.3 eV in the green visible light spectrum. The silver boranes have extremely high ion conductivity and dynamic-anion facilitate...

Silver compounds are known to be both toxic and carcinogenic. However, silver nanoparticles have been showed diagnostic and therapeutic value. They can be used as biological tags for a quantitative detection and/or be incorporated into wound dressings and cosmetics due to their antibacterial properties. Pakistani and Iranian traditional physicians still take the advantage of silver compounds, c...

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.

Silver nano-particles have been used for antibacterial purpose and it is also believed to have removal of odorous compounds, oxidation capacity as a metal catalyst. In this study, silver nano-particles in nano sizes (5-30 nm) were prepared on the surface of NaHCO3, the supporting material, using a sputtering method that provided high silver content and minimized conglomerating problems observed...

A high-performance liquid chromatographic method for the determination of penicillamine in plasma, whole blood, and urine samples is described. The method uses a commercially available electrochemical detector at a potential of +0.1 V versus the Ag/AgCl reference electrode. This method is selective and sensitive for sulfhydryl compounds. The chromatography separates penicillamine from other end...
