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.
Keithley Instruments, Inc., a world leader in advanced electrical test instruments and systems, will offer a free, web-based seminar titled 'Photovoltaic Measurements: Testing the Electrical Properties of Today?s Solar Cells'.
U.S. Department of Energy's Argonne National Laboratory scientist Tiffany Santos has been awarded a L'Oreal USA Fellowship for Women in Science for her work in materials science at the Center for Nanoscale Materials.
Argonne Center for Nanoscale Materials staff in the Nanofabrication & Devices Group together with collaborative users from the University of Wisconsin-Milwaukee have fabricated a miniaturized gas sensor using hybrid nanostructures consisting of SnO2 nanocrystals supported on multiwalled carbon nanotubes.
Researchers have demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to 'tunnel' as a pack from a state with a higher electrical current to one with a notably lower current, providing more evidence of the phenomenon of macroscopic quantum tunneling.
Over 170 businesses, research groups and other organizations are involved in the emerging field of synthetic biology throughout the United States, according to a new interactive map launched today by the Synthetic Biology Project at the Woodrow Wilson Center.
