Up-converting lasers Researchers at the University of Pennsylvania developed a filter chip that can convert the output from low-cost lasers to have the same frequency noise as big, expensive lasers, making them suitable for applications such as LiDAR. The noise in a laser's frequency is an important indicator of quality. Low-quality, noisy lasers have more random variations, making them use... » read more

Capturing waste heat Researchers at Wuhan University and University of California Los Angeles developed a hydrogel that can both cool down electronics and convert the waste heat into electricity. The thermogalvanic hydrogel consists of a polyacrylamide framework infused with water and specific ions. When they heated the hydrogel, two of the ions (ferricyanide and ferrocyanide) transferred e... » read more

One-directional optical Researchers from University of Pennsylvania, Peking University and Massachusetts Institute of Technology developed a design for optical devices that radiate light in only one direction, which could reduce energy consumption in optical fiber networks and data centers. Light tends to flow in a single direction optical fibers, but while most of the light passing through... » read more

Neuromorphic memristor Researchers at the University of Massachusetts Amherst used protein nanowires to create neuromorphic memristors capable of running at extremely low voltage. A challenge to neuromorphic computing is mimicking the low voltage at which the brain operates: it sends signals between neurons at around 80 millivolts. Jun Yao, an electrical and computer engineering researcher at ... » read more

Warmer quantum computing Researchers at the University of New South Wales Sydney, Université de Sherbrooke, Aalto University, and Keio University developed a proof-of-concept quantum processor unit cell on a silicon chip that works at 1.5 Kelvin – 15 times warmer than current chip-based technology that uses superconducting qubits. "This is still very cold, but is a temperature that can b... » read more

Flat microwave reflector Researchers from Los Alamos National Laboratory developed a new flat reflector for microwaves that could improve communications while providing a better form factor. It also breaks reciprocity, effectively turning it into a one-way mirror. The flat reflector can be reconfigured on the fly electronically, allowing it to be used for beam steering, customized focusing,... » read more
