System Bits: July 23

Superconductivity seen in trilayer graphene Stanford University and University of California at Berkeley researchers discovered signs of superconductivity in stacking three-layer sheets of graphene, they report. “It’s definitely an exciting development,” says Cory Dean, a physicist at Columbia University. Dean notes that bilayer graphene superconducts only when the atomic lattices of ... » read more

Power/Performance Bits: Feb. 11

Body heat harvesting Chemists at the University of Massachusetts Amherst developed a fabric that can harvest body heat to power small wearable electronics such as activity trackers. The device works on the thermoelectric effect created by body temperature and ambient cooler air. "What we have developed is a way to inexpensively vapor-print biocompatible, flexible and lightweight polymer fil... » read more
