New research makes it possible to predict how subjecting metals to severe pressure can lower their electrical resistance, a finding that could have applications in computer chips and other materials that could benefit from specific electrical resistance.
Physicists have overcome a major challenge in the science of measurement using quantum mechanics. The scientists developed a way to employ multiple detectors in order to measure photons in entangled states, with an experimental apparatus that uses a fiber ribbon to collect photons and send them to an array of 11 detectors. Their work paves the way for great advances in using quantum states to develop ultra-precise measurement technologies.
Time and again, even simple materials take physicists by surprise. Researchers now have observed an electronic property in the metal bismuth which they expected only in significantly more complex materials.
Scientists have developed a method using DNA origami to turn one-dimensional nano materials into two dimensions. Their breakthrough offers the potential to enhance fiber optics and electronic devices by reducing their size and increasing their speed.
Thermal systems use heat to produce cold, and vice versa. To do so, a material is needed that can dissipate water vapor particularly well and quickly. A new method simply applies this property as a layer onto the components.
