New reactor puts hydrogen from renewable fuels within reach

MINNEAPOLIS / ST. PAUL--The first reactor capable of producing hydrogen from a renewable fuel source--ethanol--efficiently enough to hold economic potential has been invented by University of Minnesota engineers. When coupled with a hydrogen fuel cell, the unit--small enough to hold in your ...

Story tips from the Department of Energy's Oak Ridge National Laboratory, September 2003

...lium cooling and a closed fuel cycle. This type of reactor is widely regarded to be inherently safer than conventional reactors, partly because the fuel consists of a kernel of fissile/fertile materials surrounded by layers of carbon and silicon carbide ceramic for protection and containment. Coated particle...

...ation exposure had none. Even workers at a nuclear reactor exposed to high levels of sparsely ionising gamma rays and mutating chemicals had very few intrachromosomal changes, though they had significant interchromosomal damage (The American Journal of Human Genetics, vol 72, p 1162). There is still a lot of...

UCR scientists modify existing chemical scrubber to environmentally friendly, all-natural filter

... biotreatment always required significantly larger reactor volumes than chemical scrubbers. In the PNAS paper, the researchers report that effective treatment of hydrogen sulfide in the converted scrubber was possible even at gas contact times as low as 1.6 seconds, comparable to usual contact times in chem...

Amorous worms reveal effects of Chernobyl

...by the radioactivity that spewed from the exploded reactor at Chernobyl in Ukraine, 17 years ago this month. Gennady Polikarpov and Victoria Tsytsugina from the Institute of Biology of the Southern Seas in Sevastopol studied the reproduction of certain sedimentary worms that are vital to aquatic ecosystems ...

Ann Arbor chemist wins national award for extracting sulfur from fuel

...levels with the current industry method would mean reactor size must increase by a factor of 15. Companies are saying they can't do that," said Yang. "So we've developed a very selective sorbent material based on crystal minerals that can do this -- and be regenerated." For Yang, who as a boy moved with his ...

New life discovered in deep ocean floor

... submarine home 300 meters below the seafloor. The reactor attempts to stabilize the stage when cellular processes are just on the border between survival and disintegration, and reproduction is none or minimal. Because the microbial activity is so minimal, it's a trial of patiently waiting for the data to s...

NEI criticizes fear-mongering by authors of used fuel paper
