“Using computer simulations, researchers are learning how lasers might be used to switch how electrons spin within magnetic materials, making room for faster magnetic memory devices. Tohoku University researchers have developed a computational simulation that shows that using ultrafast laser …
“When bonding two pieces of metal, either the metals must melt a bit where they meet or some molten metal must be introduced between the pieces. A solid bond then forms when the metal solidifies again. But researchers at MIT …
“Successful injection of tiny ripples into ultrathin magnetic films holds promise for computer chips that never overheat Faint signals detected by a RIKEN team with a sensitive optical microscope have revealed a new way to realize low-energy spintronic devices1. Iron …
“The device could reduce the carbon footprint of ethylene production A team of scientists from the National University of Singapore (NUS) has developed a prototype device that mimics natural photosynthesis to produce ethylene gas using only sunlight, water and carbon …
“Cellphone users rely on their phone cameras to capture virtually every aspect of their lives. Far too often, however, they end up with photos that are a sub-par reproduction of reality. While operator error sometimes comes into play, the camera …
“Los Alamos achieves light amplification with electrically stimulated quantum dots, critical step towards solution-processible laser diodes In a breakthrough development, Los Alamos scientists have shown that they can successfully amplify light using electrically excited films of the chemically synthesized semiconductor …
“Electronic devices such as computers generate heat that mostly goes to waste. Physicists at Bielefeld University have found a way to use this energy: They apply the heat to generate magnetic signals known as ‘spin currents’. In future, these signals …
“Red-sensitive, blue-sensitive and green-sensitive color sensors stacked on top of each other instead of being lined up in a mosaic pattern – this principle could allow image sensors with unprecedented resolution and sensitivity to light to be created. However, so far …
“On the quest for miniaturization, scientists at the Center for Integrated Nanostructure Physics, within the Institute for Basic Science (IBS, South Korea), in collaboration with researchers from the University of Birmingham and the Korea Advanced Institute of Science and Technology …
“Buzzing like a mammoth insect, the four-prop drone lifts off the ground, rising straight up. Once it reaches about four feet, it hovers for a bit, then slowly settles back to the ground. It doesn’t seem like much of …
