| Lab mimics Jupiter's Trojan asteroids inside a single atom Posted: 24 Jan 2012 01:23 PM PST Physicists have built an accurate model of part of the solar system inside a single atom. Scientists have shown that they could make an electron orbit the atomic nucleus in the same way that Jupiter's Trojan asteroids orbit the sun. The findings uphold a 1920 prediction by physicist Niels Bohr.  |
| Posted: 24 Jan 2012 12:04 PM PST Physicists have identified a property of "bilayer graphene" that the researchers say is analogous to finding the Higgs boson in particle physics. The physicists found that when the number of electrons on the BLG sheet is close to 0, the material becomes insulating -- a finding that has implications for the use of graphene as an electronic material in the semiconductor and electronics industries.  |
| New material to remove radioactive gas from spent nuclear fuel Posted: 24 Jan 2012 11:03 AM PST Research by chemists could impact worldwide efforts to produce clean, safe nuclear energy and reduce radioactive waste. They have used metal-organic frameworks to capture and remove volatile radioactive gas from spent nuclear fuel.  |
| New breed of electron interactions in quantum systems Posted: 23 Jan 2012 06:48 AM PST Physicists have observed a new kind of interaction that can arise between electrons in a single-atom silicon transistor, offering a more complete understanding of the mechanisms that govern electron conduction in nano-structures at the atomic scale.  |
| Toward lowering the power consumption of microprocessors Posted: 20 Jan 2012 03:38 PM PST The first systematic power profiles of microprocessors could help lower the energy consumption of both small cell phones and giant data centers.  |
| Chemists devise chemical reaction that holds promise for new drug development Posted: 12 Jan 2012 06:58 AM PST Scientists have devised a new method for making complex molecules. The reaction they have come up with should enable chemists to synthesize new varieties of a whole subclass of organic compounds called nitrogen-containing heterocycles, thus opening up new avenues for the development of novel pharmaceuticals and natural products ranging from chemotherapeutic compounds to bioactive plant materials such as morphine.  |
