Alacranite, As(8)S(9), has been studied by a combined approach based on micro-Raman measurements and ab initio molecular dynamics simulations, with the Car-Parrinello method. The structure of this arsenic sulfide mineral consists of an ordered packing of As(4)S(4) and As(4)S(5) cagelike

We demonstrate the fabrication of As2S3 rib waveguides using hot embossing. Because of the high temperature required, a thin (50nm) Ge(11.5)As(24)Se(64.5) was thermally evaporated on top of an 870nm As(2)S(3) layer to protect against surface degradation during embossing. The waveguides

Arsenic (As) is a toxic element frequently present in acid mine waters and effluents. Precipitation of trivalent arsenic sulphide in sulphate-reducing conditions at low pH has been studied with the aim of removing this hazardous element in a waste product

Because the toxicity of arsenic is well known, arsenic-containing compounds have frequently been ingested for suicidal purposes. We report a case of attempted suicide by massive ingestion of arsenic trisulfide, an arsenic mineral of low solubility, which resulted in minimal
