A new quantum switch for electronics

Physicists have studied a quantum point contact between two conductors with external oscillating fields applied to the contact. They found that, for some types of contacts, an increase in the oscillation frequency above a critical value reduced the current to zero - a promising mechanism that can help create nanoelectronics components.

New wearable device turns the body into a battery

The device is stretchy enough that you can wear it like a ring, a bracelet or any other accessory that touches your skin. It also taps into a person's natural heat - employing thermoelectric generators to convert the body's internal temperature into electricity.

Nanowire could provide a stable, easy-to-make superconducting transistor

Inspired by decades-old research, the new technology could boost quantum computers and other superconducting electronics.

Wafer-scale production of graphene-based photonic devices

Researchers have devised a wafer-scale fabrication technology that, thanks to predetermined graphene single-crystal templates, allows for integration into silicon wafers, enabling automation and paving the way to large scale production.

Vibrating 2D materials

Two-dimensional materials hold out hope for many technical applications. An international research team now has determined for the first time how strongly 2D materials vibrate when electronically excited with light.

Nanoparticle gel unites oil and water in manufacturing-friendly approach

Novel gel-creation method could open applications in water filtration, other areas.
