Power/Performance Bits: June 18


Multi-value logic transistor Researchers at the University of Texas at Dallas, Hanyang University, Gwangju Institute of Science and Technology, Yonsei University, Kookmin University, and Ulsan National Institute of Science and Technology developed and fabricated a transistor capable of storing intermediate values between 0 and 1. Such a multi-value logic transistor would allow more operations ... » read more

Power/Performance Bits: Feb. 6


Recycling cathodes Nanoengineers at the University of California San Diego developed an energy-efficient recycling process that restores used cathodes from spent lithium ion batteries. The process involves harvesting the degraded cathode particles from a used battery and then boiling and heat treating them. In new batteries built with the cathodes, charge storage capacity, charging time and ba... » read more

Energy-harvesting yarn Researchers at the University of Texas at Dallas and Hanyang University in South Korea developed a carbon nanotube yarn that generates electricity when stretched or twisted. Possible applications for the so-called "twistron" yarns include harvesting energy from the motion of ocean waves or from temperature fluctuations. When sewn into a shirt, these yarns served as a sel... » read more

Concentrating photovoltaics Engineers at Penn State University and the University of Illinois at Urbana-Champaign tested a new concentrating photovoltaic solar system, which they say can produce over 50% more energy per day than standard silicon solar cells. In contrast to silicon solar panels, which currently dominate the market at 15 to 20 percent efficiency, concentrating photovoltaics (... » read more

System Bits: Sept. 24


Printing nanostructures with self-assembling material A multi-institutional team of engineers from the University of Illinois at Urbana-Champaign, the University of Chicago and Hanyang University in Korea has developed a new approach to the fabrication of nanostructures for the semiconductor and magnetic storage industries. The approach combines top-down advanced ink-jet printing technology... » read more
