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 ...

...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...

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...
