Precipitation of Arsenic Trisulfide by Desulfotomaculum auripigmentum.

A newly discovered bacterium, Desulfotomaculum auripigmentum, precipitates arsenic trisulfide (As(inf2)S(inf3)). Precipitation of As(inf2)S(inf3) by this organism results from its reduction of As(V) to As(III) and S(VI) to S(-II). At the As(III) concentration range of interest (0.1 to 1 mM), the stability of As(inf2)S(inf3) is highly sensitive to pH and [S(-II)]. Thus, the relative rates at whi...

Single-step synthesis of silver sulfide nanocrystals in arsenic trisulfide

Silver sulfide nanocrystals and chalcogenide glasses (ChGs) are two distinct classes of semiconductor materials that have been exploited for new infrared technologies. Each one exhibits particular optoelectronic phenomena, which could be encompassed in a hybrid material. However, the integration of uniformly distributed crystalline phases within an amorphous matrix is not always an easy task. I...

Nanoscale phase separation in ultrafast pulsed laser deposited arsenic trisulfide „As2S3... films and its effect on plasma etching

We have observed nanoscale phase separation in amorphous arsenic trisulfide As2S3 films produced by ultrafast pulsed laser deposition and its effect on the surface morphology of the film after plasma etching. When the film was etched in CF4–O2 plasma, a grainy structure was observed on the surface. From Raman and x-ray photoelectron spectroscopies, we concluded that the grainy structure of the ...

Experimental studies on arsenic absorption routes in rats

Pentavalent inorganic arsenic was introduced by intravenous, intratracheal, gastrointestinal, and skin application in doses 0.1 to 4.0 mg/kg in rats. Isotopic technics were applied by use of As(74). It was found that the dynamics of arsenic distribution in the body as well as the kinetics of its elimination in urine and feces varies very substantially, depending on the mode of administration. I...

A trisulfide-linked glycoprotein.

The first member of a novel class of chemoselective reagents, glycosyl methanedithiosulfonates, has been synthesized, identified and employed in the first examples of chemical, site-selective construction of a trisulfide-modified protein with complete conversion.
