Walking and slithering aren’t as different as you think

The semiconductor nanosheets in the water-cooled copper mount turn an infrared laser pulse into an effectively unipolar terahertz pulse. The team says that their terahertz emitter could be made to fit inside a matchbox. Credit: Christian Meineke, Huber Lab, University of Regensburg. Courtesy: University of Michigan.

This message will self-destruct in seven days, or it can be erased with a flash of blue light. Written with UV light, the letters are marked out by molecules that shrink by storing energy, stretching the atoms of the semiconductor above. This shifts the light emitted by the semiconductor to longer wavelengths, represented in the visible spectrum by yellow on a blue background.

Self-erasing chips stop counterfeit electronics

How biomorphic batteries can provide more power for robots

Changyeong Jeong, a graduate student in electrical engineering and computer science, measures how well light passes through a sheet of flexible transparent conductor. The material sandwiches a thin layer of silver between two “dielectric” materials, aluminum oxide and zinc oxide, producing a conductive anti-reflection coating on the sheet of plastic.
