Laser action has been demonstrated in chalcogenide glass microsphere. A sub millimeter neodymium-doped gallium lanthanum sulphide glass sphere was pumped at 808 nm with a laser diode and single and multimode laser action demonstrated at wavelengths between 1075 and 1086 nm. The gallium lanthanum sulphide family of glass offer higher thermal stability compared to other chalcogenide glasses, and ...
An intramolecularly P=O-coordinated dicationic diorganotin sulphide is presented. In solution, it shows a monomer-dimer equilibrium.
Cadmium Sulphide (CdS) nanoparticles were prepared using microemulsion method using cadmium chloride as cadmium source and sodium sulphide as sulphur source. The obtained nanoparticles structures were characterized by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) whereas optical characterization was done by Ultra Violet-Visible absorption. XRD result shows that CdS nanopart...
Solec Spa is health resort in south-eastern Poland. Its unique balneorehabilitation significance worldwide is determined by chloride-iodine-sodium water with a high content of hydrogen sulphide. This water, classified as highly mineralized sodium-chloride (seltzer) sulphide, bromide, iodide, boron water, contains naturally approximately 0.9 g/l divalent sulphur compounds, which is the highest c...
ADEQUATE summaries of the literature dealing with the products resulting from the decomposition of amino-acids by various bacteria have been prepared by Stephenson [1930] and Buchanan and Fulmer [1930]. In the case of cystine a study of these reviews and of more recent literature makes it evident that previous investigators have concerned themselves with the formation ofhydrogen sulphide, ethyl...
