(Phys.org)—The market value for deuterated drugs has recently been estimated at over a billion dollars. Such drugs are simply molecules in which one or more hydrogen atoms are replaced with deuterium. While these kinds ...
(Phys.org)—As chemical reactions proceed, the reactants combine to form intermediates and those short-lived intermediates eventually become products. Reaction kinetics is concerned with how long it takes for the reaction ...
Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety.
