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...
Unlocking the mystery behind the performance decline in a promising cathode material
Jun 17, 2024 (Nanowerk News) The first generation of lithium-ion batteries for electric vehicles has been a remarkable success story. Yet, the question arises: What changes to battery materials will spur further advances to extend driving range and lower costs? A better positive electrode, or cathode, for lithium-ion batteries has...
Engineers develop highly efficient atmospheric water harvester with record-breaking clean water production
Jun 17, 2024 (Nanowerk Spotlight) Water scarcity is a growing global challenge, affecting two-thirds of the world's population to varying degrees. While atmospheric water harvesting has long been considered a potential solution, practical applications have been hindered by slow sorption kinetics (the rate at which water is absorbed), salt leakage,...
Chemical imaging more than just surface deep
Jun 17, 2024 (Nanowerk News) A new method in spectromicroscopy significantly improves the study of chemical reactions at the nanoscale, both on surfaces and inside layered materials. Scanning X-ray microscopy (SXM) at MAXYMUS beamline of BESSY II enables the investigation of chemical species adsorbed on the top layer (surface) or...
The nanotechnological revolution requires standardized ‘screws’
Jun 17, 2024 (Nanowerk News) A new nonlinear optical property of tiny particles has been discovered by an international team of scientists led by physicists at the University of Bath, with important implications for researchers working in fields as diverse as display technology, chemical catalysis and medicine. The new property...
