Twinned nanoparticles have regions of clear symmetry that share the same crystal lattice, separated by a clear boundary. Changing the twin structure can affect the properties of the nanoparticles, which makes controlling twinning to create tailored nanomaterials an active area of research....
A team of physicists from the University of Alabama in Huntsville and the Advanced Propulsion Laboratory at Applied Physics, in New York, has developed a model that shows it might be possible to create a subluminal warp drive....
Diamond is the hardest material found in nature—diamond also has the highest thermal conductivity, allowing the most heat to flow through it rapidly....
The elements in the periodic table are divided into metals, semimetals and non-metals. The distinction is based on their chemical and physical properties and is determined, in particular, by the movement of electrons and the materials' ability to conduct electrical energy: metals are excellent...
Using interference between two lasers, a research group led by scientists from RIKEN and NTT Research have created an "optical conveyor belt" that can move polaritons—a type of light-matter hybrid particle—in semiconductor-based microcavities. This work could lead to the development of new devices...
A team of scientists at the Department of Energy's SLAC National Accelerator Laboratory are developing new methods to probe the universe's minute details at extraordinary speeds....
A NIMS research team has demonstrated for the first time ever that a simple stack of thermoelectric and magnetic material layers can exhibit a substantially larger transverse thermoelectric effect—energy conversion between electric and heat currents that flow orthogonally to each other within...
Most alcohol enters the bloodstream via the mucous membrane layer of the stomach and the intestines. These days, the consequences of this are undisputed: even small amounts of alcohol impair people's ability to concentrate and to react, increasing the risk of accidents....
An experimental treatment made from a plant virus is effective at protecting against a broad range of metastatic cancers in mice, according to a new study from the University of California San Diego....
The Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has made a significant advance in laser plasma acceleration. By employing an innovative method, a research team managed to substantially exceed the previous record for proton acceleration....
