Tiny Electronic Gadget Joins Forces Between Buckyballs And Diamondoids

SLAC National Accelerator Laboratory Scientists have married two unconventional forms of carbon – one shaped like a soccer ball, the other a tiny diamond – to make a molecule that conducts electricity in only one direction. This tiny...

Chuck Bednar for redOrbit.com - Your Universe Online Thanks to one of the most sensitive neutrino detectors on Earth, physicists have for the first time confirmed the existence of low-energy neutrinos created by the “keystone” proton-proton (pp) fusion process taking place in the core of the sun, ending a search that has been going on in the scientific community for decades. The pp reaction, the researchers explain, is the first step of a reaction sequence responsible for roughly 99...

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...

Science China Press The PandaX experiment of China, which is located in the deepest underground laboratory, has released its technical design report recently. The full article will appear in SCIENCE CHINA Physics, Mechanics & Astronomy. The Particle and Astrophysical Xenon (PandaX) collaboration was established in 2009 and mainly supported by the Ministry of Science and Technology, the Ministry of Education in China,the Natural Science Foundation of China,and Shanghai Jiao Tong...

Looking For Evidence Of The Double Nature Of Neutrinos
2014-06-05 03:26:43

Technische Universitaet Muenchen Neutrinos are tiny, neutral elementary particles that, contrary to the standard model of physics, have been proven to have mass. One possible explanation for this mass could be that neutrinos are their own antiparticles, so-called Majorana particles. Though experimental evidence for this is still lacking, many theoretical extensions of the standard model of physics predict the Majorana nature of neutrinos. If this hypothesis proves to be true, many...

Pamela Fleming, spokesperson of The Institute for Basic Research, Palm Harbor, Florida, has released an open letter to the Directors of Cern laboratories in Geneva, Switzerland, containing unchallenged technical arguments showing that their ongoing test of the gravity of antimatter via alleged "anti-Hydrogen atoms" may be basically flawed, and requesting due scientific process on alternative more resolutory tests (http://www.i-b-r.org/G-Veneziano-denunciation.htm). New York,...

Turning Light Into Matter: Scientists Say 80-Year-Old Theory Is Provable
2014-05-19 08:30:22

Lawrence LeBlond for redOrbit.com - Your Universe Online First theorized in 1934 by a pair of scientists – Gregory Breit and John Wheeler – turning light into matter was deemed a fantastical and equally impossible feat. By smashing two photons together at a high rate of speed, the scientists hypothesized that it could create an electron and a positron. An occurrence of such magnitude was deemed extremely rare and difficult to reproduce. So rare that it has never been observed in any...

When chemist Tehshik Yoon looks out his office window, he sees a source of energy to drive chemical reactions. Plants “learned” to synthesize chemicals with sunlight eons ago; Yoon came to the field a bit more recently. But this week, in the journal Science, he and three collaborators detail a way to use sunlight and two catalysts to create molecules that are difficult to make with conventional techniques — a finding that may eventually have implications for drug making and materials...

Exotic Materials Study Could Lead To Advanced Electronic Devices

redOrbit Staff & Wire Reports - Your Universe Online In an attempt to help scale down the size of electronic devices to atomic dimensions, researchers from Cornell University and the Brookhaven National Laboratory have demonstrated how to convert a particular transition metal oxide from a metal to an insulator by reducing its size to less than one nanometer thick. In research currently appearing online and scheduled for publication in the May edition of the journal Nature...

Researchers Have Created A Stable Two-dimensional Electron Gas In Strontium Titanate
2014-03-04 08:12:15

Florian Aigner, Vienna University of Technology Usually, microelectronic devices are made of silicon or similar semiconductors. Recently, the electronic properties of metal oxides have become quite interesting. These materials are more complex, yet offer a broader range of possibilities to tune their properties. An important breakthrough has now been achieved at the Vienna University of Technology: a two dimensional electron gas was created in strontium titanate. In a thin layer just...

This work was recently published in Physical Review Letters In contrast to its apparent simplicity (that brought Einstein his Nobel Prize), the photoelectric effect, when an electron is knocked out from its parent atom by a photon, is quite complicated to analyze in general, especially when the atom contains a large number of electrons. Like the many-body problem in classical mechanics, the quantum many-body problem is very difficult to conceptualize and remains a serious challenge for...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
