University of Illinois at Chicago Physicists have identified the "quantum glue" that underlies a promising type of superconductivity -- a crucial step towards the creation of energy superhighways that conduct electricity without current loss. The research, published online in the Proceedings of the National Academy of Sciences, is a collaboration between theoretical physicists led by Dirk Morr, professor of physics at the University of Illinois at Chicago, and experimentalists led by...

New Light Shed On Fundamental Ultrafast Dynamics
2014-07-21 03:35:43

Kansas State University Ultrafast X-ray laser research led by Kansas State University has provided scientists with a snapshot of a fundamental molecular phenomenon. The finding sheds new light on microscopic electron motion in molecules. Artem Rudenko, assistant professor of physics and a member of the university's James R. Macdonald Laboratory; Daniel Rolles, currently a junior research group leader at Deutsches Elektronen-Synchrotron in Hamburg, Germany, who will be joining the...

DOE/Brookhaven National Laboratory Findings unequivocally link 2 'personality' changes of electrons at critical point Scientists seeking to understand the intricacies of high-temperature superconductivity—the ability of certain materials to carry electrical current with no energy loss—have been particularly puzzled by a mysterious phase that emerges as charge carriers are added that appears to compete with superconductivity. It's also been a mystery why, within this "pseudogap"...

Physicists Discover 'Quantum Droplet' In Semiconductor
2014-02-27 14:31:14

National Institute of Standards and Technology (NIST) JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle—a handful of smaller particles that briefly condense into a liquid-like droplet. Quasiparticles are composites of smaller particles that can be created inside solid materials and act together in a predictable way. A simple example is the exciton, a pairing, due to electrostatic forces, of an electron and a so-called...

Keeping Cool In The Nanoelectric Universe By Getting Hot
2014-01-22 13:52:20

University at Buffalo Research hints that nanodevices in microcircuits can protect themselves from heat generation; could boost computing power without large-scale changes to electronics As smartphones, tablets and other gadgets become smaller and more sophisticated, the heat they generate while in use increases. This is a growing problem because it can cause the electronics inside the gadgets to fail. Conventional wisdom suggests the solution is to keep the guts of these gadgets...

2-proton Bit Controlled By Single Copper Atom
2014-01-17 12:27:57

Institute of Physical Chemistry of the Polish Academy of Sciences Just a single foreign atom located in the vicinity of a molecule can change spatial arrangement of its atoms. In a spectacular experiment, an international team of researchers was able to change persistently positions of the nuclei of hydrogen atoms in a porphycene molecule by approaching a single copper atom to the molecule. A subatomic bit formed by two protons tunneling inside a simple organic molecule can be switched...

X-rays Reveal Another Feature Of High-temperature Superconductivity
2013-11-25 08:20:57

European Synchrotron Radiation Facility Discovery of a giant resonance puts these materials further apart Classical and high-temperature superconductors differ hugely in the value of the critical temperatures at which they lose all electrical resistance. Scientists have now used powerful X-rays to establish another big difference: high-temperature superconductivity cannot be accounted for by the mechanism that leads to conventional superconductivity. As this mechanism called...

Black Hole Jets Found To Contain Atomic Matter

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have long wondered exactly what the enigmatic jets given off by black holes are made of. Now, an international team of scientists, writing in the journal Nature, has apparently solved the mystery and discovered the composition of those high-speed beams of matter. Using the European Space Agency’s (ESA) XMM-Newton observatory, lead author Dr. María Díaz Trigo and colleagues studied a black hole binary system located...

This video and article explain how sudden exercise releases free radicals (loose electrons) in the body and how those electrons damage organs, tissues and can cause death. The use of electron supplementation and redistribution may lessen the effects of free radicals. Wake Forest, N.C. (PRWEB) October 21, 2013 In the medical world it's understood how excessive exercising can release free radicals and increase the risks of heart attacks, strokes and in some extreme cases even death. The...

Article in 'AIP Advances' describes new topological insulator materials developed in China and US that may speed future semiconductor chips Imagine if the "information superhighway" had HOV lanes so that data could be stored, processed and disseminated many times faster than possible with today's electronics. Researchers in the United States and China have teamed to develop such a speedway for future devices, an exotic type of electrical conductor called a topological insulator (TI). In a...
