摘要:
The invention relates to a material comprising oligoglycine tectomers and nanowires. This material is useful as an electrode, as a conductive and transparent hybrid material, and as a pH sensor, as well as in biomedical applications.
摘要:
The present invention relates to powder containing silver nanoparticles having an average particle size of 2 to 50 nm in an amount of 95% or more by mass and to applications of the powder. Silver-containing powder containing the silver nanoparticles is obtained by reducing a silver compound in the presence of a compound obtained by bonding polyethylene glycol to polyethyleneimine having a certain molecular weight and then by performing a concentration step and a drying step. A plastic substrate is obtained by directly applying a conductive paste that uses the powder on a plastic substrate and by performing drying.
摘要:
The present invention is compositions, methods of use, methods of treating, and articles of manufacture that include at least one silver iodate for imparting antimicrobial properties, particularly as it relates to the manufacture, use, and properties of medical devices. The invention also includes obtaining and using one or more silver iodate reaction products from a diperiodatoargentate, wherein the reaction products are obtained using a hydrothermal reaction.
摘要:
Gold and silver are recovered selectively such that gold and silver are separated from non-silver and non-gold material within the scrap. Gold and silver are recovered from scrap material using mixtures of acids, in some instances. The mixture comprises nitric acid and at least one supplemental acid, such as sulfuric acid or phosphoric acid. The amount of nitric acid within the mixture are relatively small compared to the amount of sulfuric acid or phosphoric acid within the mixture. The recovery of gold and silver using the acid mixtures are enhanced by transporting an electric current between an electrode and the gold and silver of the scrap material. Acid mixtures are used to recover silver from particular types of scrap materials, such as scrap material comprising silver metal and cadmium oxide and scrap material comprising silver metal and tungsten metal.
