Researchers have created the first transistors made of silicene, the world's thinnest silicon material. Their research holds the promise of building dramatically faster, smaller and more efficient computer chips.
Berkeley Lab researchers have developed a nano-sized optical antenna that can greatly enhance the spontaneous emission of light from atoms, molecules and semiconductor quantum dots. This advance opens the door to light-emitting diodes (LEDs) that can replace lasers for short-range optical communications, including optical interconnects for microchips, plus a host of other potential applications.
Small magnetic whirls may revolutionize future data storage and information processing if they can be moved rapidly and reliably in small structures. A team of scientists has now been able to investigate the dynamics of these whirls experimentally.
A team of physicists has developed a method to monitor the properties of microscopic particles as they grow within a chemical reaction vessel, creating new opportunities to improve the quality and consistency of a wide range of industrial and consumer products. Their work offers benefits for commodities ranging from food and pharmaceuticals to perfumes and cosmetics.
Scientists have developed a molecular sensor to measure 'crowding' in cells, which reflects the concentration of macromolecules present. The sensor provides quantitative information on the concentration of macromolecules in bacteria and in mammalian cells.
