During their experiments the Empa scientists observed that the excited molecules began to hop about and move around, rotating about their own axes. They also underwent very rapid 'inversion', that is, flipping over into their mirror image shape.
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.
NTSI and CTSI today announced today that the recently held TechConnect World trio of conferences, which included Clean Technology '09, Nanotech '09, and the TechConnect Summit events, drew a record number of attendees, speakers, and vendors to the George R. Brown Convention Center in Houston.
The chemical mechanism that occurs on the surface of an automotive catalytic converter has been deciphered thanks to an observation speed record established by Frederic Thibault-Strarzyk at the Laboratoire Catalyse et Spectrochimie in Caen.
A team of physicists and engineers have demonstrated all-fibre quantum logic, where single photons are generated and used to perform the contolled-NOT quantum logic gate in optical fibres with high fidelity.
Leading lithographers from North America, Asia and Europe will gather in Honolulu, Hawaii, July 13-17 for the 2009 International Workshop on EUV Lithography to discuss potential solutions to critical technical issues on bringing extreme ultraviolet lithography (EUVL) into high-volume manufacturing.
Molecules with five-fold symmetry arrange themselves on a surface as a two-dimensional crystal, although theoretically this ought not to be possible. Recently researchers at Empa and the University of Zurich have taken the first steps to a better understanding of this 'impossible' behavior by monitoring the complicated crystallization process with a scanning tunnel microscope.
Most chemical elements become superconducting at low temperatures or high pressures, but until now, copper, silver, gold, and the semiconductor germanium, for example, have all refused superconductivity. Scientists were now able to produce superconducting germanium for the first time.
While the perils associated with particle physics, from Earth-gobbling black holes to Vatican-destroying amounts of antimatter, gain news headlines, it?s easy to overlook the large economic and societal benefits of particle physics research.
Imagine being able to detect in just a few minutes whether someone is infected with a virus. This has now become a reality, thanks to a new ultra-sensitive detector that has been developed by Ostendum, a spin-off company of the University of Twente.
