Word History and Origins
Example Sentences
"It was quite surprising to find that a modern electron acceptor like F5H had partnered with an ancient protein to develop new biochemical machinery that synthesizes the advanced lignin structure."
This phenomenon arises from the creation of an acceptor level capable of accommodating electrons in the absence of sufficient oxygen, thereby enabling the material to function as a p-type semiconductor.
The research team further revealed that Y6-PAs exhibit higher miscibility with the donor polymer compared to small molecular acceptors of the same type.
"In semiconductor physics, we have already strategically used defects that we call donors or acceptors, which help us build diodes and transistors. So strategically, defects can certainly help us build up new kinds of technologies."
Luo explains that glycerol acts as a hydrogen donor and choline chloride acts as a hydrogen acceptor.
