electron flow

electron flow

[i′lek‚trän ‚flō]
(electricity)
A current produced by the movement of free electrons toward a positive terminal; the direction of electron flow is opposite to that of current.

This coupling between charge and orientation has a dramatic effect on the electron flow across the molecule, manifested by a large conductance gap at low bias voltages.
Under strong illumination, cyclic electron flow increases, generating a large proton gradient required for the formation of nonphotochemical quenching (NPQ) within the antenna, protecting PSII against excess light.
When gas flows over the Ionix Static Eliminator's patented membrane, it is converted from an insulator, which resists electron flow, to a conductor, which facilitates it.
This coating helps to eliminate dulling, oxide build-up which inhibits electron flow and dims the image.
When the alloy is properly modified, the silicon plates change into fibers, which present a much smaller impediment to electron flow, and the conductivity is increased.
History, Safety, Atomic Structure and Electron Flow
Respiratory complexes are macromolecular batteries coupling electron flow through a wire of metal clusters and cofactors with proton transfer across the inner membrane of mitochondria and bacteria.
But graphene has one major and perhaps fatal flaw: Turning off the electron flow through the material is difficult.
With carbon nanotubes appearing to act as a "prosthetic photoabsorber," photosynthetic activity -- measured by the rate of electron flow through the thylakoid membranes -- was 49 percent greater than that in isolated chloroplasts without embedded nanotubes.
Graphene single-electron pump (SEP), the joint innovation by the National Physical Laboratory (NPL) and the University of Cambridge, provides the speed of electron flow needed to create a new standard for electrical current based on electron charge.
Winkler developed laser flash-quench methods that opened the way for experimental investigations that have led to a deeper understanding of the mechanisms of electron flow through proteins that function in respiration and photosynthesis.
