A potential new state of matter is being reported in the journal Nature, with research showing that among superconducting materials in high magnetic fields, the phenomenon of electronic symmetry breaking is common.
EPFL scientists have developed a new method to efficiently measure electron transfer in dye-sensitized transition-metal oxide photovoltaics.
University of Groningen scientists led by physics professor Bart van Wees have created a graphene-based device, in which electron spins can be injected and detected with unprecedented efficiency. The result is a hundredfold increase of the spin signal, big enough to be used in real life applications, such as new spin transistors and spin-based logic. The research, part of the European Union's €1 billion Graphene Flagship, was published in Nature Communications on Aug. 15.
Rice University materials scientists replace all the atoms on top of a three-layer, two-dimensional crystal to make a transition-metal dichalcogenide with sulfur, molybdenum and selenium. The new material has unique electronic properties that may make it a suitable catalyst.
Chip makers appreciate what most consumers never knew: silicon's virtues include the fact that it 'rusts' in a way that insulates its tiny circuitry. Two new ultrathin materials share that trait and outdo silicon in other ways that make them promising materials for electronics of the future.
A research collaboration between the University of Illinois at Urbana-Champaign, the National Institute of Standards and Technology, and the University of Maryland has revealed a new technique by which scattering of sound waves from disorder in a material can be suppressed on demand. All of this, can be simply achieved by illuminating with the appropriate color of laser light.
Researchers have studied grain boundaries for decades and gained some insight into the types of properties grain boundaries produce, but no one has been able to nail down a universal system to predict if a certain configuration of atoms at grain boundaries will make a material stronger or more pliable. An interdisciplinary team of BYU researchers have cracked the code by juicing a computer with an algorithm that allows it to learn the elusive 'why' behind the boundaries' qualities.
For the first time, Jena University physicists used extreme ultraviolet radiation (XUV) for this process, which was generated in their own laboratory, and they were thus able to perform the first XUV coherence tomography at laboratory scale. This radiation has a wavelength of between 20 and 40 nanometres - from which it is therefore just a small step to the X-ray range.
A new type of photoinitiator for (3-D printing in water could further the development of biomedical accessories, bring advances in traditional industries such as plastics, and offer an environmentally friendly approach to additive manufacturing.
A newly discovered collective rattling effect in a type of crystalline semiconductor blocks most heat transfer while preserving high electrical conductivity - a rare pairing that scientists say could reduce heat buildup in electronic devices and turbine engines, among other possible applications.
