Scientists discover zero-sound oscillations of atomic wavelength in super-chilled helium Scientists working at the Institut Laue-Langevin, one of the world's leading centres for neutron science, have carried out the first investigation of two-dimensional fermion liquids using neutron scattering, and discovered a new type of very short wave-length density wave. The team believe their discovery will interest researchers looking at electronic systems, since high temperature superconductivity...

Researchers at the National Institute of Standards and Technology (NIST) have done a mash-up of two very different experimental techniques–neutron scattering and electrochemical measurements–to enable them to observe structural changes in nanoparticles as they undergo an important type of chemical reaction. Their recently published technique allows them to directly match up particle size, shape and agglomeration with the "redox" chemical properties of the particles. The...

Scientists Make New Neutron Star Discovery

Researchers from several universities have detected all phases of thermonuclear burning in a neutron star for the first time. The team discovered the "model burster" star located close to the center of the galaxy in the global cluster Terzan 5. The star is the first of its kind to burst the way that models predict, and it could help explain why a model star like it has gone undetected for so long. Astrophysicists have been studying neutron stars for decades to try and understand how...

Individual atoms of a certain chemical element can be very stubborn when it comes to separation, mainly because techniques rely on a difference in chemical and physical properties – atoms are almost identical in both regards. However, if you peer closely enough into the atoms, there are subtle differences that can have very big effects. These "different" atoms, called isotopes, are heavily relied on in areas of medicine and nuclear energy and now researchers have proposed a novel way...

New physical phenomenon could drastically reduce energy consumption by computers Three years ago Professor Christian Pfleiderer and his team from the physics department at the TUM discovered an entirely new magnetic structure in a silicon manganese crystal — a grid of magnetic eddies. Together with the team of Professor Achim Rosch from the University of Cologne, he studied the properties of these eddies, so-called skyrmions, named after the British physicist Tony Skyrme, who...

To better understand the fundamental behavior of molecules at surfaces, researchers at the U.S. Department of Energy's Oak Ridge National Laboratory are combining the powers of neutron scattering with chemical analysis. Scientists have a fundamental interest in how molecules behave at solid surfaces because surface interactions influence chemistry, such as in materials for catalysis, drug delivery and carbon sequestration. Understanding these interactions allows researchers to tailor...

Scientists at Universidad Carlos III de Madrid (UC3M), Oxford University (United Kingdom) and the University of Michigan (USA) have joined efforts to develop new materials for thermonuclear fusion reactors. Their research focuses on characterization of oxide dispersion-strengthened, reduced-activation steel for the reactor structure. Thermonuclear fusion promises to be a possible solution to the current energy crisis. It is produced when two atomic nuclei of light elements combine to...

An advance in sensor design* by researchers at the National Institute of Standards and Technology (NIST) and the University of Waterloo's Institute of Quantum Computing (IQC) could unshackle a powerful, yet high-maintenance technique for exploring materials. The achievement could expand the technique–called neutron interferometry–from a test of quantum mechanics to a tool for industry as well. Neutron beams can be used in dozens of ways to probe complex molecules and other...

Image 1 - Potential Mission Would Reveal The Hearts Of Undead Stars

Neutron stars have been called the zombies of the cosmos, shining on even though they're technically dead, and occasionally feeding on a neighboring star if it gets too close. They are born when a massive star runs out of fuel and collapses under its own gravity, crushing the matter in its core and blasting away its outer layers in a supernova explosion that can outshine a billion suns. The core, compressed by gravity to inconceivable density — one teaspoon would weigh about a...

X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...
