Jul 13, 2023 (Nanowerk News) Astronomers at the University of Sydney have shown that a small, faint star is the coldest on record to produce emission at radio wavelength. The ‘ultracool brown dwarf’ examined in the study is a ball of gas simmering at about 425 degrees centigrade – cooler...
A ferroelectric transistor that stores and computes at scale
Jul 13, 2023 (Nanowerk News) The Big Data revolution has strained the capabilities of state-of-the-art electronic hardware, challenging engineers to rethink almost every aspect of the microchip. With ever more enormous data sets to store, search and analyze at increasing levels of complexity, these devices must become smaller, faster and...
First nanoscale direct observation of how glass transforms into liquid at increasing temperature
Jul 13, 2023 (Nanowerk News) Researchers from the Universitat Autònoma de Barcelona and the ICN2 have developed a methodology that makes it possible for the first time to observe under the microscope, in real time, what happens when glass is heated and changes to a supercooled liquid phase, known as...
Researchers develop approach that can enable inexpensive mass manufacturing of micro-LED displays
Jul 13, 2023 (Nanowerk News) Researchers have demonstrated a continuous roller printing process that can pick up and transfer over 75,000 micrometer-scale semiconductor devices in a single roll with very high accuracy. The new method paves the way to creating large-scale arrays of optical components and could be used to...
3D Glasses for topological materials
Jul 13, 2023 (Nanowerk News) They are seen as a beacon of hope for energy-saving electronics and the high-tech of the future: topological quantum materials. One of their properties is the conduction of spin-polarized electrons on their surface - even though they are actually non-conductive inside. To put this into...
Astronomers find answers to mysterious action of ghost stars in our Galaxy
Jul 13, 2023 (Nanowerk News) A collaboration of scientists from The University of Manchester and the University of Hong Kong have found a source for the mysterious alignment of stars near the Galactic Centre. The alignment of planetary nebulae was discovered ten years ago by a Manchester PhD student, Bryan...
Establishing ethical nanobiotechnology
Jul 13, 2023 (Nanowerk News) Prosthetics moved by thoughts. Targeted treatments for aggressive brain cancer. Soldiers with enhanced vision or bionic ears. These powerful technologies sound like science fiction, but they’re becoming possible thanks to nanoparticles. And, as with any great power, there comes great responsibility. “In medicine and other...
