(Phys.org) -- In a bit of inspired research, a diverse team of researchers has devised a means for measuring the time it takes for an electron to tunnel through a barrier. Led by Israel's Weizmann Institute of Science, Dror ...
As electronic circuits shrink from finely etched lines in silicon wafers to nearly elusive proportions, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and Columbia University are studying ...

(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 ...
Nearly 1,000 times thinner than a human hair, nanowires can only be understood with quantum mechanics. Using quantum models, physicists from Michigan Technological University have figured out what drives the efficiency of ...
