electron carrier

n.
Any of various molecules, such as cytochromes and quinonoid compounds, that accept one or two electrons from one molecule and donate them to another in the process of electron transport, resulting in the release of energy that is used to produce ATP.

Recently a Japanese laboratory reported the existence of superconducting oxides that contain electron carriers. However, the material becomes superconducting only when cooled to below 30 K, making it useless for any practical HTS devices.
Replacing the lanthanum with an electron-packed rare-earth element such as neodyn-dum (Nd), he theorized, should create conditions ideal for electron carriers. He started with planar Nd (sub 2)CUO(sub 4) and doped the material with cerium (Ce), which added epical oxygens to the copper-oxygen plane.
