Cobalt sits in the center of the corrin ring of vitamin B12 and the important cobalamins we derive from it. Perhaps surprisingly, only two of our enzymes bother to use these painfully constructed and meticulously channeled ...
(Phys.org) —A team of chemists working in Germany has finally, after decades of debate, solved the crystal structure of the nonclassical 2-norbornyl carbocation. In their paper published in the journal Science, the team ...
At TU Wien (Vienna), it has become possible to control one of the most important chemical processes: switching oxygen molecules between a reactive and unreactive state.
