Alan McStravick for redOrbit.com - Your Universe Online Theoretical Physics made a huge leap from concept to reality yesterday thanks to collaboration between an international team of scientists and researchers with the U.S. Department of Energy´s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab). The team has proposed the experimental design of a space-time crystal that is based on an electric-field ion trap and the Coulomb repulsion of particles that carry...

A new model provides an alternative description of atomic level gold bonding A study on how gold atoms bond to other atoms using a model that takes into account bonds direction has been carried out by physicist Marie Backman from the University of Helsinki, Finland, and colleagues. These findings, which are about to be published in EPJ B, are a first step toward better understanding how gold binds to other materials through strong, so-called covalent, bonds. What scientists need is an...

New and Improved Model of Molecular Bonding from Researchers at Berkeley Lab´s Molecular Foundry Material properties and interactions are largely determined by the binding and unbinding of their constituent molecules, but the standard model used to interpret data on the formation and rupturing of molecular bonds suffers from inconsistencies. A collaboration of researchers led by a scientist at the U.S Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley...

The powerful new technique should appeal to chemists at pharmaceutical companies and research institutions Scientists at The Scripps Research Institute have developed a powerful new technique for manipulating the building-block molecules of organic chemistry. The technique enables chemists to add new functional molecules to previously hard-to-reach positions on existing compounds–making it easier for them to generate new drugs and other organic chemicals. "This is a basic tool for...

A team of chemists at the University of Geneva have finally demonstrated the utility of the rare halogen bond which acts as a anions transporter Professor Stefan Matile does not mention whether, as a child, he was a big fan of Lego. However, as an adult, he is fascinated by the game of molecular construction. Using the rules of chemistry, it is possible to artificially assemble all kinds of molecules and even nanomachines. However, chemists in this area feel their creativity constrained...

Scientists at the Vienna University of Technology found a method to locate single gold atoms on a surface. This should pave the way to better and cheaper catalysts. Most people value large chunks of gold — but scientists at the Vienna University of Technology are interested in gold at the smallest possible scale, because single gold atoms are potentially the most reactive catalysts for chemical reactions. However, when gold atoms are placed on a surface they tend to ball up into tiny...

Berkeley Lab scientists and their colleagues have discovered an unsuspected way that protons can move among molecules -- revealing new opportunities for research in biology, environmental science, and green chemistry When a proton — the bare nucleus of a hydrogen atom — transfers from one molecule to another, or moves within a molecule, the result is a hydrogen bond, in which the proton and another atom like nitrogen or oxygen share electrons. Conventional wisdom has it that...

A team of international researchers have fired ultra-fast shots of light at oxygen, nitrogen and carbon monoxide molecules as part of a development aimed at mapping the astonishingly quick movements of atoms within molecules, as well as the charges that surround them. The ultra-short laser that spans only a few hundred attoseconds — an attosecond is equivalent to one quintillionth of a second — was fired in a sample of molecules and could pave the way towards imaging the...

Researchers from Stanford University and the U.S. Department of Energy's SLAC National Accelerator Laboratory have created the first-ever system of "designer electrons" — exotic variants of ordinary electrons with tunable properties that may ultimately lead to new types of materials and devices. "The behavior of electrons in materials is at the heart of essentially all of today's technologies," said Hari Manoharan, associate professor of physics at Stanford and a member of SLAC's...
