The new layered ternary sulfide, Nb(1.30)Cr(0.70)S(5), niobium chromium penta-sulfide, is isostructural with the solid solution Nb(1+x)V(1-x)S(5) and belongs to the FeNb(3)Se(10) structure type. Each layer is composed of two unique chains of face-sharing [NbS(8)] bicapped trigonal prisms (m symmetry) and edge-sharing [MS(6)] (M= Nb, Cr) octa-hedra (m symmetry). One of the two metal sites is occ...
The abundances of hyperthermophilic heterotrophs, methanogens, and autotrophic reducers of amorphous Fe(III) oxide in 18 samples of deep-sea hydrothermal vent sulfide chimneys of the Endeavour Segment were measured. The results indicate that conditions favor the growth of iron reducers toward the interiors of these deposits and that of heterotrophs toward the outer surfaces near high-temperatur...
Recently a new process for the synthesis of the commercially important semi-crystalline, engineering thermoplastic poly(p-phenylene sulfide/disulfide), PPS/DS, was presented [1]. This process, based on the reaction of p-diiodobenzene (DIB) and sulfur at elevated temperatures (Figure 1), generates a polymeric material containing para-substituted aromatic groups connected by sulfide and disulfide...
There have been reports of chemical attacks in which sulfur mustard might have been used (a) on Iranian soldiers and civilians during the Gulf War in 1984 and 1985 and (b) in an Iraqi chemical attack on the Iranian-occupied village of Halbja in 1988, resulting in many civilian casualties. Heavy use of chemical warfare in Afghanistan by the Soviet military is a recent innovation in military tact...
Background and Aim: In breach of all international conventions, Iraq frequently used chemical weapons against both military and civilian targets in its 8-year war with Iran. The most frequently used agent was sulfur mustard. The effects of mustard gas may be divided into early and late categories. Late lesions, due to the agent's mutagenic and carcinogenic potential, are mainly the results of i...
Anthraquinone based polymer as high performance cathode material for rechargeable lithium batteries.
Poly(anthraquinonyl sulfide) is synthesized and investigated as a novel organic cathode material for rechargeable lithium batteries, which shows excellent reversibility and cyclabilty, and gives important insights into developing a new generation of organic cathode materials with higher performance.
Degradation products that could reasonably form upon storage of sulfur mustard have been synthesized and analyzed by GC/MS. Elucidation of the fragmentation pathways was accomplished by means of B3LYP/6-31+G(d) calculations.
prevalence of oral soft tissue lesions in the victims of chemical bombardments in kerman city (2007)
normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 introduction : during iran-iraq war, iraqi troops used chemical weapons especially sulfur mustard (sm) gas against the iranian soldiers several times. results of previous studies and observations have all emphasized that chemical weapons pose hazardous effects on different human organs such as lungs, skin, hematopoietic ti...
Corneal and plasma lipids were studied in a rabbit model to gain insight into the pathogenesis of secondary lipid keratopathy. Rabbits were divided into four groups in which a high cholesterol diet and corneal suture placement were varied to produce lipid keratopathy. In rabbits with lipid keratopathy, quantitative thin layer chromatography revealed that cholesterol esters comprised most of the...
Aims: Pigmentation disorders are one of the main skin problems due to mustard gas exposure in chemically-injured veterans. The aim of this study as part of the Sardasht cohort study was to investigate the association between IL-6 and IL-4 and pigment disorders in chemically-injured veterans exposed to mustard gas. Materials & Methods: In this study, 500 subjects including 372 people expose...
