Scientists at the National Institute of Standards and Technology (NIST) have developed a novel instrument that can make three kinds of atom-scale measurements simultaneously.
Scientists have made a pivotal breakthrough in the important, emerging field of spintronics -- which could lead to a new high speed energy efficient data technology.
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.
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.
Scientists at PPPL have gained new insight into a common type of plasma hiccup that interferes with fusion reactions. These findings could help bring fusion energy closer to reality.
Materials scientists have synthesized a new type of perovskite--one of the most common crystal structures of materials deployed for a range of uses, from superconductors to photovoltaics--that goes against conventional thinking about how such structures behave at extreme pressures such as those that exist deep in the Earth.
Steering and monitoring the light-driven motion of electrons inside matter on the time-scale of a single optical cycle is a key challenge in ultrafast light wave electronics and laser-based material processing. Physicists from the Max Born Institute in Berlin and the University of Rostock have now revealed a so-far overlooked nonlinear optical mechanism that emerges from the light-induced tunneling of electrons inside dielectrics.
