(Phys.org) —A team of researchers working at China's University of Science and Technology has succeeded in developing a chemical mapping technique capable of revealing the constituent atoms of a single molecule. In their ...
(Phys.org)—A new study by a team of chemists in Greece has added credence to a theory that suggests that humans differentiate smells by sensing molecular vibrations, rather than through simple binding to receptors. In their ...
By focusing light down to the size of an atom, scientists at the University of California, Irvine have produced the first images of a molecule's normal modes of vibration—the internal motions that drive the chemistry of ...
