Electric fields catalyse graphene’s energy and computing prospects

Jun 19, 2024 (Nanowerk News) Researchers at the National Graphene Institute have made a groundbreaking discovery that could revolutionise energy harnessing and information computing. Their study, published in Nature ("Control of proton transport and hydrogenation in double-gated graphene"), reveals how electric field effects can selectively accelerate coupled electrochemical processes in...

Discovery of one-dimensional topological insulator

Jun 19, 2024 (Nanowerk News) A joint research team has unveiled a new topological insulator (TI), a unique state of matter that differs from conventional metals, insulators, and semiconductors. Unlike most known TIs, which are either three-or two-dimensional, this TI is one-dimensional. The breakthrough will lead to further developments of...

What happens when neutron stars collide?

Jun 18, 2024 (Nanowerk News) When stars collapse, they can leave behind incredibly dense but relatively small and cold remnants called neutron stars. If two stars collapse in close proximity, the leftover binary neutron stars spiral in and eventually collide, and the interface where the two stars begin merging becomes...

Scientists print custom bioelectronics directly on skin

Jun 18, 2024 (Nanowerk Spotlight) Wearable bioelectronic devices have emerged as a promising approach for monitoring health and delivering targeted therapies. These devices can capture physiological signals from organs like the heart, muscles, and brain to detect disease or control prosthetics. They can also deliver electrical stimulation to the skin,...

Astronomers see a massive black hole awaken in real time

Jun 18, 2024 (Nanowerk News) In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), to track how the galaxy’s brightness has...

The dark side of transmission X-ray microscopy

Jun 18, 2024 (Nanowerk News) X-ray microscopes are essential for examining components and materials because they can be used to detect changes and details in the material. Until now, however, it has been difficult to detect small cracks or tiny inclusions in the images. By developing a new method, researchers...

Ultra-high spectral purity revealed in exciton-polariton laser

Jun 18, 2024 (Nanowerk News) Exciton-polariton lasers, renowned for their low-power operation, have long tantalised researchers with their promise for practical low-energy applications. However, until now, a clean measurement of the laser’s linewidth, or spectral purity, has remained elusive. “The spectral purity is one of the defining characteristics of a...

Molecular sponge for the electronics of the future

Jun 17, 2024 (Nanowerk News) An international research team led by Dr Florian Auras from Dresden University of Technology (TUD) has succeeded in developing a new type of material in the rather young research field of covalent organic frameworks. The new two-dimensional polymer is characterised by the fact that its...
