Crystallization of Cristobalite in Sodium Borosilicate Glass in the Presence of CrO.

Glass containing chromium is a promising material for use in various modern fields of application (laser technology, optoelectronic devices, and luminescent resources). Chromium oxides are well-known nucleating agents that can cause crystallization. One of the most commonly observed crystalline phases in silicate glasses is cristobalite, which lowers their mechanical strength, leading to the destruction of the material.

Photo-oxygenation of water media using photoactive plasmonic nanocomposites.

Plasmonic nanocomposites ZnO-Ag and ZnO-SnO-Ag(AgCl) were prepared by the polymer-salt method, and their structure and morphology were studied using XRD and SEM analyses. It was found that the addition of photoactive inorganic nanocomposites ZnO-Ag and ZnO-SnO-Ag(AgCl) in pure water significantly enhances the effectiveness of its disinfection and purification during UV treatment and provides the effective water oxygenation. Oxygen photogeneration under blue light (λ = 405 nm) can be related to the plasmon-excitation processes in ZnO-SnO-Ag(AgCl) composites.

[Medical care provision to the victim children of Haiti].

Treatment and diagnostic measures, including anesthesia during catastrophes and natural disasters are a world known problem. The paper presents the experience of anesthetic care provision during specialized surgical care to the victim children of the earthquake in Haiti. The materials of analysis were 529 anesthesias conducted to 72 children, who were in the treatment for crush syndrome, skeletal and concomitant injury.
