-The chemical compositions ofchlorite-smectite mixed-layered minerals (C/S) from the Ohyu caldera (lnoue, 1985) are analyzed using M+-4Si-3R 2§ diagrams. The assumed original saponite has the following composition: Si3.54Alo.460 ~ 0Alo. ~7~Fe 2§ ~.385Mg1.z95Mn0.o2(OH)2M+o.56. Random C/S minerals ( 100 to 80% expandable layers) are interpreted as an interstratification of the starting 2:1 smecti...

When exposed to a maximum level of 100 ppm chlorine dioxide in their drinking water, neither A/J or C57L/J mice exhibited any hematologic changes. Chlorite exposure under similar conditions produced increases for red blood cells in osmotic fragility, mean corpuscular volume, and glucose-6-phosphate dehydrogenase activity for both strains. Chlorite exposure of pregnant A/J mice resulted in a sig...

-The chemical composition of mixed-layer serpentine/chlorite (Sp/Ch) in Tuscaloosa Formation sandstone was analyzed by energy dispersive X-ray spectroscopy (EDX) in the scanning electron miscroscope (SEM) and by X-ray diffraction (XRD). EDX results indicate little depth-controlled variation in composition, whereas XRD results suggest distinct decreases in octahedral Fe and tetrahedral A1. XRDde...

A newly discovered Naomugeng lithium mineralization area is located to the east of Central Asian Orogenic Belt (CAOB). The hosted in volcanic rocks Manketou’ebo Formation. altered mainly consist quartz, orthoclase, chlorite, montmorillonite, calcite, and dolomite. Here, we present integrated studies petrography, mineralogy, geochemistry (with an average Li2O content 0.43 wt.%) collected from dr...

Chlorite dismutases (Clds) are heme b-containing prokaryotic oxidoreductases that catalyze the reduction of chlorite to chloride with the concomitant release of molecular oxygen. Over time, they are irreversibly inactivated. To elucidate the mechanism of inactivation and investigate the role of the postulated intermediate hypochlorite, the pentameric chlorite dismutase of "Candidatus Nitrospira...

Chlorine dioxide (ClO2) is a strong oxidant that possesses an antimicrobial activity. We demonstrated here that ClO2 gas is easily generated by mixing 3.35% sodium chlorite solution (Purogene) and 85% phosphoric acid at a 10:1 volume ratio without using an expensive machine. In a test room (87 m(3)), experiments were carried out using various amounts of sodium chlorite solution (0.25 ml/m(3) to...
