Fluorine gas (F 2), which has been called chemistry’s hellcat, is so reactive that chemists have long assumed it does not occur in nature. Now researchers in Munich have evidence that the gas exists ...

Fluorine gas is so reactive that any naturally-occurring whiffs cannot exist for more than a few fleeting seconds. At least, that has been the conventional wisdom for more than a century. Now, ...

Researchers have developed a new theoretical model explaining one way to make black silicon. The new etching model precisely explains how fluorine gas breaks certain bonds in the silicon more often ...
