Researchers have created the fastest man-made spinning object in the world, which they believe will help them study material science, quantum mechanics and the properties of vacuum.
Metallic glasses are an exciting research target, but the difficulties associated with predicting how much energy these materials release when they fracture is slowing down development of metallic glass-based products. Recently, researchers developed a way of simulating to the atomic level how metallic glasses behave as they fracture. This modeling technique could improve computer-aided materials design and help researchers determine the properties of metallic glasses. They report their findings in the Journal of Applied Physics.
A new theoretical study explains previous mystifying experimental results, in which coupled charged particles moved in exactly the opposite direction to that predicted. This apparently contradictory phenomenon is associated with the bandgap in dual-layer graphene structures, a bandgap which is very much smaller than in conventional semiconductors.
The international team of scientist of Peter the Great St. Petersburg Polytechnic University (SPbPU), Leibniz University Hannover (Leibniz Universität Hannover) and the Ioffe Institute found a way to improve nanocomposite material which opens new opportunities to use it in hydrogen economy and other industries. The study is dedicated to the composite material, a semiconductor based on titanium dioxide. Its applications are widely studied by the researchers all over the world.
Studying the photochemistry has shown that ultraviolet radiation can set off harmful chemical reactions in the human body and, alternatively, can provide 'photo-protection' by dispersing extra energy. To better understand the dynamics of these photochemical processes, a group of scientists irradiated the RNA base uracil with ultraviolet light and documented its behavior on a picosecond timescale. They discuss their work this week in The Journal of Chemical Physics.
A new study by MIT and others proves Einstein is right again. The most thorough test yet finds no Lorentz violation in high-energy neutrinos.
Latest calculation based on how subatomic muons interact with all known particles comes out just in time for comparison with precision measurements at new 'Muon g-2' experiment.
Australian scientists have achieved a new milestone in their approach to creating a quantum computer chip in silicon, demonstrating the ability to tune the control frequency of a qubit by engineering its atomic configuration. The work has been published in Science Advances.
An international team of scientists that includes UC Riverside physicist Hai-Bo Yu has imposed conditions on how dark matter may interact with ordinary matter. In the search for direct detection of dark matter, the experimental focus has been on WIMPs, or weakly interacting massive particles, the hypothetical particles thought to make up dark matter. But the research team invokes a different theory to challenge the WIMP paradigm: the self-interacting dark matter model, or SIDM.
The VERITAS array has confirmed the detection of high-energy gamma rays from the vicinity of a supermassive black hole located in a distant galaxy, TXS 0506+056. While these detections are relatively common for VERITAS, this black hole is potentially the first known astrophysical source of high-energy cosmic neutrinos, a type of ghostly subatomic particle that can be made at astrophysical sources of ultra-high energy cosmic rays.
