Apr 08, 2022 (Nanowerk News) Predicting how climate and the environment will change over time or how air flows over an aircraft are too complex even for the most powerful supercomputers to solve. Scientists rely on models to fill in the gap between what they can simulate and what they...
Differences between the Moon’s near and far sides linked to colossal ancient impact
Apr 08, 2022 (Nanowerk News) The face that the Moon shows to Earth looks far different from the one it hides on its far side. The nearside is dominated by the lunar mare — the vast, dark-colored remnants of ancient lava flows. The crater-pocked far side, on the other hand,...
The challenges and prospects of lithium-CO2 dioxide batteries
Apr 08, 2022 (Nanowerk News) The lithium-carbon dioxide battery is an emerging energy storage and conversion device. Although development of these batteries is still in its infancy, scientists need a thorough understanding of the critical problems that must be overcome for these batteries to achieve their potential as new energy...
First integrated laser on lithium niobate chip
Apr 08, 2022 (Nanowerk News) For all the recent advances in integrated lithium niobate photonic circuits — from frequency combs to frequency converters and modulators — one big component has remained frustratingly difficult to integrate: lasers. Long haul telecommunication networks, data center optical interconnects, and microwave photonic systems all rely...
Smarter 3D printing makes better parts faster (w/video)
Apr 08, 2022 (Nanowerk News) 3D printers may soon get better at producing intricate metal and plastic parts, thanks to new software developed at the University of Michigan that reduces harmful heat buildup in laser powder bed fusion printers. Called SmartScan, the software demonstrated a 41% improvement in heat distribution...
Engineered crystals could help computers run on less power
Apr 08, 2022 (Nanowerk News) Computers may be growing smaller and more powerful, but they require a great deal of energy to operate. The total amount of energy the U.S. dedicates to computing has risen dramatically over the last decade and is quickly approaching that of other major sectors, like...
Astronomers discover a new type of freak stars covered in helium burning ashes
Apr 08, 2022 (Nanowerk News) A German team of astronomers from the Universities of Tübingen and Potsdam, led by Prof. Klaus Werner, have discovered a new type of weird stars. Their findings were published in Monthly Notices of the Royal Astronomical Society ("Discovery of hot subdwarfs covered with helium-burning ash")....
A jump through time – new technique rewinds the age of skin cells by 30 years
Apr 08, 2022 (Nanowerk News) Research from the Babraham Institute has developed a method to ‘time jump’ human skin cells by 30 years, turning back the ageing clock for cells without losing their specialised function. Work by researchers in the Institute’s Epigenetics research programme has been able to partly restore...
Researchers develop glass-in-glass fabrication approach for making miniature IR optics
Apr 07, 2022 (Nanowerk News) Researchers have developed a new fabrication process that allows infrared (IR) glass to be combined with another glass and formed into complex miniature shapes. The technique can be used to create complex infrared optics that could make IR imaging and sensing more broadly accessible. “Glass...
The hunt for the gravitational wave background
Apr 07, 2022 (Nanowerk News) Coalescing supermassive black holes in the centers of merging galaxies fill the universe with low-frequency gravitational waves. Large radio telescopes have already looked for the subtle effect of these spacetime ripples on radio waves emitted by pulsars within our Galaxy. Now, an international team of...
