Power/Performance Bits: Dec. 1


Self-erasing chip Researchers from the University of Michigan developed self-erasing chips that could be used to prevent counterfeiting or detect tampering. The technology is based on a new material that temporarily stores energy, changing the color of the light it emits. It self-erases in a matter of days, or it can be erased on demand. "It's very hard to detect whether a device has been t... » read more

More stable quantum states Researchers at the University of Chicago found a way to make quantum systems retain coherency 10,000 times longer. The fragile nature of quantum states remains a challenge for developing practical applications of quantum computing, as they can be easily disrupted by background noise coming from vibrations, temperature changes or stray electromagnetic fields. Ap... » read more

Waste plastic supercapacitor Researchers from the University of California Riverside found a way to recycle waste plastic into energy storage devices. The work focused on polyethylene terephthalate plastic waste, or PET, which is found in soda bottles and many other consumer products. The researchers first dissolved pieces of PET plastic bottles in a solvent. Using electrospinning, they fab... » read more
