Superconducting chips to become reality

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.

Particle physics is not just black holes and antimatter

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.

New gas sensor based on multiwalled carbon nanotubes

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.

Evidence of macroscopic quantum tunneling detected in nanowires

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.
