Scientists have pioneered a new technique to produce arrays of sound produced entirely by heat.
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range - and they are unrivalled in terms of weight.
Physicists at Martin Luther University Halle-Wittenberg (MLU) and Lanzhou University in China developed a simple concept that could improve significantly magnetic-based data processing. Using ultrashort electric pulses in the terahertz range, data can be written, read and erased very quickly. This would make data processing faster, more compact and energy efficient. The researchers confirmed their theory by running complex simulations and the results were published in the journal NPG Asia Materials.
Japanese scientists have elucidated the mechanism of the hydrodynamic power generation using spin currents in micrometer-scale channels, finding that power generation efficiency improves drastically as the size of the flow is made smaller. They experimentally demonstrated the fluid power generation phenomenon in the laminar flow region and confirmed that in the laminar flow region, energy conversion efficiency was increased by approximately 100,000 times.
A research team of Mainz University has developed a technique that will potentially halve the energy required to write data to servers and make it easier to construct complex server architectures.
Researchers have introduced a novel wearable device and set of algorithms specifically tailored to catch early signs and symptoms associated with COVID-19 and to monitor patients as the illness progresses.
New research by Carnegie's Olivier Gagné and collaborator Frank Hawthorne of the University of Manitoba categorizes the causes of structural asymmetry, some surprising, which underpin useful properties of crystals, including ferroelectricity, photoluminescence, and photovoltaic ability.
Artificial light at night attracts insects, thus giving invasive cane toads in places like Australia a lot more food to eat, researchers have found, potentially giving a boost to such invasions.
Scientists at the University of Tsukuba create a theoretical carbon-based material that would be even harder than diamond. This work may have industrial applications for cutting and polishing in place of current synthetic diamond.
Researchers have developed a computational model that helps users understand how changes in the nanostructure of materials affect their conductivity - with the goal of informing the development of new energy storage devices for a wide range of electronics.
