Superconducting refrigerator cools via tunneling cascade

(Phys.org) —Cooling microscopic objects to temperatures near absolute zero requires unconventional refrigeration technologies. One microscale cooling method is superconducting refrigeration, in which refrigerators extract ...

Scientists 'fingerprint' nanoscale objects and viruses

Spanish scientists at the University of Barcelona have found a way of effectively identifying nanoscale objects and viruses that could offer a breakthrough for biomedical diagnostics, environmental protection and nano-electronics

Are electron tweezers possible? Apparently so

(PhysOrg.com) -- Not to pick up electrons, but tweezers made of electrons. A recent paper by researchers from the National Institute of Standards and Technology (NIST) and the University of Virginia (UVA) demonstrates that ...
