Power/Performance Bits: Aug. 2


From sun to hydrocarbon fuel Researchers at the University of Illinois at Chicago have engineered a solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy. Unlike conventional solar cells, which convert sunlight into electricity that must be stored in heavy batteries, the new device converts atmosph... » read more

Contender emerges for 3D IC semiconductor material While silicon has few serious competitors as the material of choice in the electronics industry, transistors cannot keep shrinking to meet the needs of next-gen devices given the significant physical limitations of energy consumption and heat dissipation. To address this, researchers at Harvard University have achieved a reversible change in e... » read more

System Bits: July 29


Cooper Pairs Researchers at the University of Illinois at Chicago, Cornell University and Brookhaven National Laboratory say they have unlocked what they’re calling quantum glue—the underlying basis for creating energy conduits without current loss. In superconductors, electrical resistance vanishes below a critical temperature and conduction electrons form ordered pairs, known as Coop... » read more
