The Tiny Star Explosions Powering Moore’s Law

Cars That Think

Supernova explosions, the catastrophic self-destruction of certain types of worn-out stars, are intimately tied to life on Earth because they are the birthplaces of heavy elements across the universe. Mirrors could not achieve the same focusing precision as the previous lens-plus-water combination.

Inorganic mercury converted to more toxic and bio-accumulative monomethylmercury in ocean waters, possibly by microbes

Green Car Congress

A team led by the University of Alberta has confirmed that inorganic mercury (Hg) found worldwide in ocean water is transformed into monomethylmercury (MMHg)—a potent and bio-accumulative neurotoxin—in the seawater. In a 1991 paper discussing concerns with mercury and monomethylmercury, William F. 159-166.

Chalmers team develops method to reduce levels of mercury in sulfuric acid

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a method that can reduce the levels of mercury in sulfuric acid by more than 90%, even from low levels. It is therefore a worldwide challenge that sulfuric acid often contains one of the most toxic substances: mercury.

ORNL study identifies more biopathways for formation of toxic methylmercury

Green Car Congress

More forms of mercury can be converted to methylmercury—a form of mercury that can be taken into the food chain and eventually can result in mercury-contaminated fish—than previously thought, according to a study led by a team of researchers from Oak Ridge National Laboratory (ORNL) published in Nature Geoscience.

Duke study finds China’s synthetic natural gas plants will have heavy environmental toll; 2x vehicle GHG if used for fuel

Green Car Congress

Coal-powered synthetic natural gas (SNG) plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers published in the journal Nature Climate Change.

Qatar Petroleum and UOP to research more efficient treatment of natural gas

Green Car Congress

UOP’s separation technology and equipment remove contaminants such as water, carbon dioxide and sulfur compounds (hydrogen sulfide, mercaptans, etc.) Its gas technologies extract water, mercury, sulfur compounds, carbon dioxide and other contaminants from raw natural gas.
