Gold is one of the most inert metals, forming very few compounds, and only a them are currently known to be superconducting. Here we have found yet another chemical compound gold (and silver) that

Surface-enhanced Raman scattering (SERS) spectra of methionine (Met) containing dipeptides: Met-X and X-Met, where X is: L-glycine (Gly), L-leucine (Leu), L-proline (Pro), and L-phenylalanine (Phe) are reported. Using pre-aggregated Ag colloid we obtained high-quality SERS spectra of these compounds spontaneously adsorbed on colloidal silver. Additionally, we measured Raman spectra (RS) of thes...

This publication provides a comparative description of the chemical composition silver speedwell (Veronica incana L.). We chose three different regions Yakutia as objects study, namely: Megino-Kangalas District (Central Yakutia); Vilyuisk (Western Oymyakon (Eastern Yakutia). The content certain groups substances (phenolic compounds, tannins, flavonoids, and phenylpropanoids) in vegetable raw ma...

The lack of comprehensive studies on silver paints in manuscripts is a handicap to new stabilization strategies and treatments. This work develops and tests a methodological approach for the study of the degradation of silver paints, at the molecular level, using as a case study a French Book of Hours dated from the 15th century from Mafra National Palace collection. In this paper, we show that...

plants or natural resources have been found to be a good alternative method for nanoparticles synthesis. in this study, polyaniline coated silver nanoparticles (agnps) synthesized from piper betle leaves extract were investigated for their antibacterial activity. silver nanoparticles were prepared from the reduction of silver nitrate and nabh4 was used as reducing agent. silver nanoparticles an...

This study was conducted to synthesize and characterize 1,3-dialkyl-5,6-dimethyl-benzimidazolium salts their silver complexes. Four novel silver(I)-N-heterocyclic carbene complexes were synthesized characterized by mass analyses, FT-IR NMR spectroscopy. The biological capacity of the compounds evaluated in vitro for antimicrobial antitumor activities. minimum inhibitory concentration (MIC) dete...
