New chip eliminates the need for specific decoding hardware, could boost efficiency of gaming systems, 5G networks, IoT, and more. Every piece of data that travels over the internet — from paragraphs in an email to 3D graphics in a virtual reality environment — can be altered by the noise it encounters along the way, such as electromagnetic interference from a microwave or Bluetooth device. The data are coded so that when they arrive at their destination, a decoding algorithm can undo the negative effects of that noise and retrieve the original data...

Researchers Develop New Tool for Analyzing Large Superconducting Circuits

Method could help push forward the field of quantum computing. The next generation of computing and information processing lies in the intriguing world of quantum mechanics. Quantum computers are expected to be capable of solving large, extremely complex problems that are beyond the capacity of today’s most powerful supercomputers.

New research tools are needed to advance the field and fully develop quantum computers. Now Northwestern University researchers have developed and tested a theoretical tool for analyzing large superconducting circuits. These circuits use superconducting quantum bits, or qubits, the smallest units of a quantum computer, to store information.

Circuit size is important since protection from detrimental noise tends to come at the cost of increased circu...

Stretching the Capacity of Flexible Energy Storage

Abstract Image

Some electronics can bend, twist and stretch in wearable displays, biomedical applications and soft robots. While these devices’ circuits have become increasingly pliable, the batteries and supercapacitors that power them are still rigid. Now, researchers in ACS’ Nano Letters report a flexible supercapacitor with electrodes made of wrinkled titanium carbide — a type of MXene nanomaterial — that maintained its ability to store and release electronic charges after repetitive stretching.

One major challenge stretchable electronics must overcome is the stiff and inflexible nature of their energy storage components, batteries and supercapacitors...

Light-emitting diodes made from perovskite nanocrystals (green) embedded in a metal-organic framework can be created at low cost, use earth-abundant materials and remain stable under typical working conditions. (Image by Los Alamos National Laboratory.)

A breakthrough in stabilizing nanocrystals introduces a low-cost, energy-efficient light source for consumer electronic devices, detectors and medical imaging.

Light-emitting diodes (LEDs) are an unsung hero of the lighting industry. They run efficiently, give off little heat and last for a long time. Now scientists are looking at new materials to make more efficient and longer-lived LEDs with applications in consumer electronics, medicine and security.

Researchers from the U.S...
