TL;DR: The ability to tune the release of biocidal Ag(+) ions from these composites by controlling the size of the embedded AgBr nanoparticles is demonstrated, potentially useful as antimicrobial coatings in a wide variety of biomedical and general use applications.
Abstract: We present a simple method of fabricating highly potent dual action antibacterial composites consisting of a cationic polymer matrix and embedded silver bromide nanoparticles. A simple and novel technique of on-site precipitation of AgBr was used to synthesize the polymer/nanoparticle composites. The synthesized composites have potent antibacterial activity toward both gram-positive and gram-negative bacteria. The materials form good coatings on surfaces and kill both airborne and waterborne bacteria. Surfaces coated with these composites resist biofilm formation. These composites are different from other silver-containing antibacterial materials both in the ease of synthesis and in the use of a silver salt nanoparticle instead of elemental silver or complex silver compounds. We also demonstrate the ability to tune the release of biocidal Ag+ ions from these composites by controlling the size of the embedded AgBr nanoparticles. These composites are potentially useful as antimicrobial coatings in a wide va...

TL;DR: The autometallographic procedure represents a new technique that can substitute for the normal methods of physical development (PD) and can also be applied to ultrathin sections.
Abstract: The autometallographic procedure represents a new technique that can substitute for the normal methods of physical development (PD). The physical developer (a solution of reducing substance, silver salt and protection colloid) is replaced by a photographic emulsion and chemical developer. Accumulations of gold, silver, metal sulphides and metal selenides can be amplified by the present technique. Tissue sections placed on glass slides are covered by a silver bromide containing emulsion, dried and exposed to a chemical developer. After development the emulsion is either removed or cleared and the sections are counterstained and embedded. The autometallographic procedure can also be applied to ultrathin sections.

TL;DR: The absorption spectra of pure silver bromide and silver chloride crystals grown from the melt have been measured in and near the so-called "absorption edge", where the absorption coefficient increases very rapidly with frequency as mentioned in this paper.
Abstract: The absorption spectra of pure silver bromide and silver chloride crystals grown from the melt have been measured in and near the so-called "absorption edge," where the absorption coefficient increases very rapidly with frequency. The temperature-dependence of the absorption edge has also been investigated. More limited data have been collected on the absorption spectra of mixed AgBr---AgCl and AgBr---AgI crystals.

TL;DR: In this article, an AgBr/SiO2 catalyst prepared from Schumann emulsion has been used for photolysis of CH3OH/H2O solution under UV illumination, H2 generation was observed and hydrogen was continuously evolved for 200 h without destruction of AgBr although Ag0 was detected by X-ray diffraction analysis after the reaction.
Abstract: A AgBr/SiO2 catalyst prepared from Schumann emulsion has been used for photolysis of CH3OH/H2O solution. Under UV illumination, H2 generation was observed and hydrogen was continuously evolved for 200 h without destruction of AgBr although Ag0 was detected by X-ray diffraction analysis after the reaction. It is presumed that the hydrogen production from methanol in distilled water occurs on the Ag0 and the support plays important roles for the photocatalysis as well as TiO2/SiO2 (J. Phys. Chem. B 1997, 101, 2611).
