Lower carbon dioxide emissions from coal-fueled power plants possible with technology development

...eveloping and testing similar technology to remove hydrogen sulfide and carbon dioxide from natural gas. Rochelle will share one third of the TXU funds with other colleagues in the university’s College of Engineering and in the Jackson School of Geosciences. These colleagues will help test how well the pr...

Deep in the ocean, a clam that acts like a plant

...g on symbiotic bacteria to use energy locked up in hydrogen sulfide to replace sunlight. Now, the genome of th...r cells billions of years ago. "The energy from hydrogen sulfide is used to drive carbon fixation in much the same way that chloroplasts carry out carbon fix...

Researchers create artificial enzyme that mimics the body's internal engine

...terious forms of reduced oxygen are superoxide and hydrogen peroxide, which have been implicated in cancer, heart failure, Alzheimer's disease and other illnesses, he added. The good news is that CcO rarely fails, said Stanford postdoctoral fellow Neal K. Devaraj, whose doctoral dissertation was the basis ...

New biofuels process promises to meet all US transportation needs

... for producing liquid fuels from biomass by adding hydrogen from a "carbon-free" energy source, such as solar ...r power, during a step called gasification. Adding hydrogen during this step suppresses the formation of carbon dioxide and increases the efficiency of the proc...

Soft-cell approach cuts animal tests

...; fire combustion products, including cyanide, hydrogen sulphide, and ammonia; and, the volatile organic compounds (VOCs) xylene and toluene, found in solvents used by the printing, painting, and petrochemical industries. The in vitro method "opens new possibilities for toxicity testing of indus...

Using nanomagnets to enhance medical imaging

...gnetic ions, which alter the nuclear properties of hydrogen in water, offer the advantage of consistent identical design but provide low contrast. The second category encompasses particles of thousands of atoms or crystals, which alter local magnetic fields; they provide contrast variation in a larger region ...

Simulations unravel outer membrane transport mechanism

...plied a force to TonB and showed that the multiple hydrogen bonds between TonB and the luminal domain were strong enough to remain intact while TonB pulled the end of the luminal domain away from the barrel. The simulation also showed the luminal domain gradually unfolding, changing its conformation in ways t...
