Experimental Results Relating to the Influence of Hot Electrons (Electrical Current Flow through the Catalyst) on Catalyzed ReactionsIt is shown experimentally with various chemical reactions that hot electrons (electrons having some energy excess above the Fermi level) flowing from inside the catalyst ...
- + There are 2 types of current: AC – Alternating Current – changes direction periodically. DC – Direct Current – always flows in the same direction. Direction of ‘conventional’ current Electrons flow in the opposite direction - + Conventional current is the flow of imaginary positive par...

One electron makes current flow: a single electron pumped in and out of a quantum dot could be useful as a calibration standard for electronics or as the basic unit of a quantum computer.(APPLIED PHYSICS) Even the smallest components in a modern desktop computer use tens of thousands of ele...
Electrons are found in shells orbiting the nuclei of atoms and can also move freely through space as cathode rays in a cathode-ray tube or as beta particles emitted by radioactive nuclei, or flow in a current through a conducting material impelled by an electric potential difference. [electr(...
