There are numerous ways to begin chemical reactions in liquids, but adding free electrons right into water, ammonia, or other liquid solutions is particularly appealing for green chemistry because solvated electrons are naturally clean and do not produce any byproducts when they react.
Researchers at Rice University and the University of Texas at Austin observed that when it comes to packing charge-acceptor molecules on the surface of semiconducting nanocrystals, more is really not better.
