A heterojunction AgBr/Ag/AgCoO2 nanocomposite was synthesized by hydrothermal followed deposition precipitation method. The morphology, crystallinity and band structure of the nanoparticles were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD) UV–Vis diffuse reflectance spectroscopy (UV DRS). beads prepared coating material on petrocoke with aid chitosan. performa...

Metastable fragmentation channels of free silver bromide clusters (AgnBrp) + are reported. The large majority release a neutral trimer (AgBr)3. This is interpreted in the frame of ab initio DFT calculations with 19-electron pseudopotential on silver atom. The stability, the structural and electronic properties of (AgnBrp) (+) (n = 6, p = n, n− 1) are examined. The structures of the clusters are...

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-ne...

Investigations have been carried out on the distribution of AgBr-grains in unexposed photographic plates (type Q2, 11 f o r d Ltd.) used for ion detection in mass-spectrometers. Electron micrographs show that a large fraction of the grains protrude about halfway out of the gelatine matrix and that these grains are covered by a very thin gelatine layer on the side facing the ions. The mean proje...

A novel Ag/AgBr/BiOBr hybrid was prepared by a rational in situ ion exchange reaction between BiOBr hierarchical microspheres and AgNO(3) in ethylene glycol followed by light reduction, which displayed superior visible light driven photocatalytic activities in sterilization of pathogenic organism and degradation of organic dye compared to N-doped P25.

AgBr nanoplates with exposed {111} facets have been synthesized in high yield by a facile precipitation reaction, and the as-prepared nanoplates exhibited greatly enhanced photocatalytic properties for the degradation of organic pollutants, which may be primarily ascribed to the relatively higher surface energy of {111} facets.

An investigation of the critical behavior strongly interacting quantum chromodynamics (QCD) matter has been performed by analyzing fluctuation observables on event-by-event (ebe) basis measured in high-energy collision experiments. The analysis is using nuclear interactions at different target sizes and colliding beam energies as a function varying width pseudorapidity interval. For sake compar...

A pairwise additive interaction potential (including a shell model to account for ion polarizabilities) was developed for describing crystalline AgBr. It was constructed by fitting experimental data, including lattice constant, phonon frequencies at the r and X points, dielectric constant, cohesive energy, and elastic constants. The predicted results compare favorably with experimentally measur...
