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.
I could just stand up and draw a nice circuit diagrams but whatwe do is get all kids in a circle to act out the electron flow
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.
