EVIDENCE1 is available to indicate that in the reduction of some aromatic molecules at the dropping mercury electrode one electron is added on to the neutral molecule.

Remark: In some textbooks the number in the parenthesis can be found superscript (like 4d7), but that is a minor detail. And what is that good for? The existence of defined orbitals and shells can ...

This electron emission type has been known for about 50 years, but its cause was previously unclear. It is something quite common in physics: Electrons leave a certain material, fly away and are ...

SOME time ago it was found that in dilute solutions of polyethylene, particularly of ‘Marlex 50’, single crystals may be formed which can be made visible by means of electron microscopic ...

Scanning electron microscopes are one of those niche instruments that most of us don’t really need all the time, but would still love to have access to once in a while. Although we’ve c… ...
