Latest Sulfide Stories

By Anonymous Two engineers at the University of California, Riverside are part of a binational team that has found semiconducting nanotubes produced by living bacteria-a discovery that could help in the creation of a new generation of nanoelectronic devices. The research team believes this is the first time nanotubes have been shown to be produced by biological rather than chemical means. It opens the door to the possibility of cheaper and more environmentally friendly manufacture of...

Haber, Inc, (OTC: HABE), a Massachusetts-based company with proprietary technology for environmentally friendly processing of precious metal-bearing ores, announced today that it has developed a low-cost process to treat sulfides in ores for use in conjunction with its proprietary gold extraction and recovery technologies and its "Aladdin" ore processing machine. Haber independently developed this sulfide reduction chemistry specifically to treat refractory sulfide ores. The presence of...

By Sheng, Yanqing Chen, Fanzhong; Wang, Xinming; Sheng, Guoying; Fu, Jiamo ABSTRACT: Odorous volatile organic sulfides (VOSs) in headspace atmosphere and wastewaters were identified and quantified synchronously in two municipal wastewater treatment plants (WWTPs) in Guangzhou, China. Dimethyl sulfide (DMS), with concentrations ranging from 0.66 to 5.41 mg/m^sup 3^, was the major VOS in air samples. Carbonyl sulfide (COS), carbon disulfide (CS^sub 2^), and dimethyl disulfide (DMDS) ranged...

Science fiction usually sticks hibernating spaceflyers in glowing capsules of goo, but a real-life ingredient for suspended animation may not be too far off, scientists say. Hydrogen sulfide is the key stinky compound in rotting eggs and swamp gas. New research shows it can slow down a mouse's metabolism, or the consumption of oxygen, without dampening the flow of blood. "A little hydrogen sulfide gas is a way to reversibly and, apparently, safely cut metabolism...

HELSINKI (Reuters) - Finnish engineers have poured pig manure into a contaminated pond next to an old mine, saying the bacteria in the slurry will clean up metals in the water.Mining company Outokumpu dumped 450 cubic meters of pig slurry into the waste water near the closed Kangasjarvi mine, which once produced zinc, copper and sulfur."Pig slurry contains bacteria that bind metals that are in the mine water and they will sink to the bottom. We have used this system to clean mine waters...

CHAPEL HILL -- Sustained elevation of the suicide rate in a North Carolina county may be linked to releases of hydrogen sulfide and other airborne chemicals from a nearby paper mill and possibly other industrial sites, a new study led by a University of North Carolina at Chapel Hill psychiatrist indicates. The findings are being presented today (Nov. 7) to the 18th Annual U.S. Psychiatric and Mental Health Congress in Las Vegas.This is the second study to propose a possible link between...

NASA -- NASA exobiology researchers confirmed Earth's oceans were once rich in sulfides that would prevent advanced life forms, such as fish and mammals, from thriving. The research was funded in part by NASA's exobiology program. A team of scientists from the Massachusetts Institute of Technology and Harvard University, working with colleagues from Australia and the United Kingdom, analyzed the fossilized remains of photosynthetic pigments preserved in 1.6 billion-year-old rocks from the...

By Nicole Mordant VANCOUVER, British Columbia (Reuters) - A small Canadian company is helping some of the world's biggest miners clean up their polluted waste water in a novel process that it says pays for itself. BioteQ Environmental Technologies Inc. says its water treatment method offers hope that the seepage of heavy metals from abandoned mine sites, which kills and harms aquatic life often for decades as no one wants to foot the bill, can be arrested. The Vancouver, British...
