Substantial advances for applications of nanocrystals in the fields requiring a continuous output of photons and high quantum efficiency may soon be realized due to discovery of non-blinking semiconductor nanocrystals. This discovery recently announced by scientists at the Naval Research Laboratory (NRL), University of Rochester, Cornell University and Eastman Kodak Company is an important step to the use of the nanocrystals in various practical devices ranging from low-threshold lasers to...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear.
