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.

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.
