KARLSRUHE, Germany, April 14, 2011 /PRNewswire/ -- The exploitation and utilization of new energy sources are considered to be among today's major challenges. Solar energy plays a central role, and its direct conversion into chemical energy, for example hydrogen generation by water splitting, is one of its interesting variants. Titanium oxide-based photocatalysis is the presently most efficient, yet little understood conversion process. In cooperation with colleagues from Germany and abroad, scientists of the KIT Institute for Functional Interfaces (IFG) have studied the basic mechanisms of photochemistry by the example of titania and have presented new detailed findings.
Even though hydrogen production from water and sunlight by means of oxide powders has been studied extensively for s...

They share the same problem. Their properties border a proposed injection well that could pump hundreds of thousands of gallons a day of oilfield waste into the ground. This waste, known in the industry as "production water," is mostly oily saltwater used in drilling. But it also contains substances such as waste crude, sludge from storage pits and tank bottoms, used glycol, amine, and hydrogen sulfide scrubber liquid, to name only a few. There are at least 26 acknowledged chemicals in the waste, including such known carcinogens as benzene and one category unhelpfully listed as "other." It's not the kind of stuff [Cecile Carson] wants in the drinking water she brings up from her well. Yet the Railroad Commission doesn't classify oil and gas waste as hazardous. That means the commission,...

Acetaldehyde, a toxic byproduct of alcohol (i.e., ethanol) metabolism, has long been suspected of causing at least some of the central nervous system actions of ethanol. However, the data to support such a hypothesis have been difficult to obtain. One roadblock is the very low blood levels of acetaldehyde following ethanol intake and the finding that even elevated acetaldehyde levels in the blood do not easily gain access to the brain. The recent discovery of the oxidation of ethanol to acetaldehyde in the adult brain may help explain the acute effects of ethanol.

Coal is the primary source of energy used in the United States today. It accounts for one-third of the nation's total energy production. It is the source of 50 percent of the total electricity generated nationwide. It is by far the most abundant American energy source and it accounts for 90 percent of America's fossil energy reserves. During the Industrial Revolution, coal was the fuel that powered the transformation of the United States from an agricultural society into the greatest economic power in the world. Today, it is the direct and indirect source of hundreds of thousands of jobs and billions of dollars in economic impact. Abundant and affordable, coal-fired electricity is the life force of the American economy. It is America's best friend. American coal was used 1,000 years ag...
