 | The Bohr Model describes the atom as a nucleus circled by electrons, much like a star circled by planets -- but quantum theory taught us that particles do not travel on well-defined trajectories but behave as a quantum wave. Now scientists succeeded in preparing atoms which indeed behave like a miniature version of a solar system. ...> Full Article |
Research by a team of Sandia National Laboratories chemists could impact worldwide efforts to produce clean, safe nuclear energy and reduce radioactive waste.

Physicists at the University of New South Wales 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.

University of Notre Dame nuclear physicists Philippe Collon and Michael Wiescher are using accelerated ion beams to pinpoint the age and origin of material used in pottery, painting, metalwork and other art. The results of their tests can serve as powerful forensic tools to reveal counterfeit art work, without the destruction of any sample as required in some chemical analysis.

 | The "AmpaCity" project has been kicked off: The RWE Group and its partners are just about to replace a 1-kilometer-long high-voltage cable connecting two transformer stations in the Ruhr city of Essen with a state-of-the-art superconductor solution. This will mark the longest superconductor cable installation in the world. As part of this project, the Karlsruhe Institute of Technology will analyze suitable superconducting and insulating materials. ...> Full Article |
To better understand the fundamental behavior of molecules at surfaces, researchers at the US Department of Energy's Oak Ridge National Laboratory are combining the powers of neutron scattering with chemical analysis.

Researchers have devised a proposal for the first conclusive experimental test of a phenomenon known as 'Bell's nonlocality.' This test is designed to reveal correlations that are stronger than any classical correlations, and do so between high-energy particles that do not consist of ordinary matter and light. These results are relevant to the so-called 'CP violation' principle, which is used to explain the dominance of matter over antimatter.

Heisenberg's uncertainty principle is one of the foundations of quantum physics. Recent experiments show that Heisenberg's view of quantum uncertainty was not complete.

Ultra hot quark-gluon-plasma, generated by heavy-ion collisions in particle accelerators, is supposed to be the "most perfect fluid" in the world. Previous theories imposed a limit on how "liquid" fluids can be. Recent results at the Vienna University of Technology suggest that this limit can be broken -- making the world's "most perfect fluid" even more perfect.

Using several massive supercomputers, a team of physicists has split a simulated electron perfectly in half. The results, which were published in the Jan. 13 issue of Science, are another example of how tabletop experiments on ultra-cold atoms and other condensed-matter materials can provide clues about the behavior of fundamental particles.

A Rice University laboratory has found a way to turn common carbon fiber into graphene quantum dots, tiny specks of matter with properties expected to prove useful in electronic, optical and biomedical applications.

New evidence this week supports a theory developed five years ago at Rice University to explain the electrical properties of unconventional superconductors and other classes of materials that have long vexed scientists. Physicists say the new findings in Nature Materials represent an important step toward the ultimate goal of creating a unified theoretical description of quantum effects in electronic materials at the border of magnetism and superconductivity.

A better understanding of the universe will be the outgrowth of the discovery of the Higgs boson, according to a team of University of Oklahoma researchers. The team predicts the discovery will lead to supersymmetry or SUSY -- an extension of the standard model of particle physics. SUSY predicts new matter states or super partners for each matter particle already accounted for in the standard model. SUSY theory provides an important new step to a better understanding of the universe we live in.

 | Two teams at the US Department of Energy's Fermilab and Lawrence Berkeley National Laboratory have independently made the largest direct measurements of the invisible scaffolding of the universe, using the gravitational lensing effect known as "cosmic shear" to build maps of the distribution of dark matter. Their methods show that surveys with ground-based telescopes can measure cosmic shear with enough accuracy to aid in better understanding the mysterious space-stretching effects of dark energy. ...> Full Article |
