New nanotransistors keep their cool at high voltages
Power converters play an essential role in electric vehicles and solar panels, for example, but tend to lose a lot of power in the form of heat in the electricity conversion process. Thanks to a new type of transistor developed at EPFL, these converters can perform at substantially improved efficiencies, especially in high-power applications.

A Touch of Silver
Carnegie Mellon University In the field of robotics, metals offer advantages like strength, durability and electrical conductivity. But, they are heavy and rigid - properties that are undesirable in soft and flexible systems for wearable computing and human-machine interfaces. Hydrogels, on the other hand, are lightweight, stretchable and biocompatible, making them excellent materials for contact lenses and tissue engineering scaffolding.

Joint project with Birmingham's Tyseley Energy Park and the University of Birmingham. Demonstrates the potential of cost-effective decarbonisation through more effective utilisation and coordination of current and planned generation assets. A more coordinated net zero system could supply up to 50,000 users with CO2-neutral electricity or supply Birmingham airport with green electricity, heat and cooling.

Microchips of the Future: Suitable Insulators are Still Missing
Until now, hexagonal boron nitride was considered the insulator of choice for miniaturised transistors. New investigations by TU Wien (Vienna) show: this may not be the way to go. For decades, there has been a trend in microelectronics towards ever smaller and more compact transistors. 2D materials such as graphene are seen as a beacon of hope here: they are the thinnest material layers that can possibly exist, consisting of only one or a few atomic layers.

Benefits of the UK’s first affordable energy positive house are confirmed
Savings of up to £1,000 a year on energy bills could be made by living in the UK's first affordable energy positive house, researchers have shown. The team from Cardiff University say that over the course of a year the house exports 1.3 times more electricity to the grid than it consumes, thus resulting in overall net negative carbon emissions, equating to around -179 kg per year.

Electrically switchable qubit can tune between storage and fast calculation modes
Electrically switchable qubit can tune between storage and fast calculation modes
To perform calculations, quantum computers need qubits to act as elementary building blocks that process and store information. Now, physicists have produced a new type of qubit that can be switched from a stable idle mode to a fast calculation mode. The concept would also allow a large number of qubits to be combined into a powerful quantum computer, as researchers from the University of Basel and TU Eindhoven have reported in the journal -Nature Nanotechnology-.

Pseudospin in antiferromagnets: new perspectives for information technologies Elementary particles carry an intrinsic angular momentum known as their spin. For an electron, the spin can take only two particular values relative to a quantization axis, letting us denote them as spin-up and spin-down electrons.
