Sophisticated electron-imaging technique reveals widespread "destruction," offering clues to how material works as a superconductor It's a basic technique learned early, maybe even before kindergarten: Pulling things apart - from toy cars to complicated electronic materials - can reveal a lot about how they work. "That's one way physicists study the things that they love; they do it by destroying them," said Séamus Davis, a physicist at the U.S. Department of Energy's (DOE)...

Scientists develop new nanomaterial that ℠steers´ current in multiple dimensions Scientists at Northwestern University have developed a new nanomaterial that can "steer" electrical currents. The development could lead to a computer that can simply reconfigure its internal wiring and become an entirely different device, based on changing needs. As electronic devices are built smaller and smaller, the materials from which the circuits are constructed begin to lose their...

A research group led by ETH Zurich has now, for the first time, visualized the motion of electrons during a chemical reaction. The new findings in the experiment are of fundamental importance for photochemistry and could also assist the design of more efficient solar cells. In 1999, Ahmed Zewail was awarded the nobel prize in chemistry for his studies of chemical reactions using ultrashort laser pulses. Zewail was able to watch the motion of atoms and thus visualize transition states on...

Physicists establish dynamic Jahn-Teller effect in defective diamonds A University at Buffalo-led research team has established the presence of a dynamic Jahn-Teller effect in defective diamonds, a finding that will help advance the development of diamond-based systems in applications such as quantum information processing. "We normally want things to be perfect, but defects are actually very important in terms of electronic applications," said Peihong Zhang, the UB associate professor...

Diamond, nature's hardest known substance, is essential for our modern mechanical world — drills, cutters, and grinding wheels exploit the durability of diamonds to power a variety of industries. But diamonds have properties that may also make them excellent materials to enable the next generation of solid-state quantum computers and electrical and magnetic sensors. To further explore diamonds' quantum computing potential, researchers from the University of Science and Technology of...

Image 1 - Illinois Researchers Localize 3D Matter Waves

A new University of Illinois study, demonstrating how material defects can affect three-dimensional conduction, could profoundly alter ultrasonic waves used in medical imaging, lasers, superconductors, and more, the college reported in a press release Friday. The study, which was led by physics professor Brian DeMarco, resulted in complete localization of quantum matter waves in three dimensions, which was reportedly originally theorized some 50 years ago. DeMarco and his colleagues...

Nobel Chemistry Prize Awarded To Daniel Shechtman

The Nobel prize for chemistry was awarded to an Israeli scientist whose work was once ridiculed for being out of line with received thinking. Daniel Shechtman, from the Israel Institute of Technology (Technion), won the entire $1.5 million 2011 Nobel prize for chemistry on Wednesday for discovering different ways in which atoms could be packed together in solid materials. His work has opened the door for experiments in the use of quasicrystals. The Royal Swedish Academy of Sciences said...

Researchers at Oregon State University have created a new, unifying method to describe a basic chemical concept called “electronegativity,” first described almost 80 years ago by OSU alumnus Linus Pauling and part of the work that led to his receiving the Nobel Prize. The new system offers simplicity of understanding that should rewrite high school and college chemistry textbooks around the world, even as it opens important new avenues in materials and chemical research, with...

Quantum logic is quite a new and absolutely fascinating field of physics and might - ultimately - lead to the fabrication of a quantum computer. And it could also aid the search for the "theory of everything" - the missing link between traditional physics and quantum physics. One of the fundamental questions hereby is whether fundamental constants possibly vary. To prove this in the case of the fine-structure constant, for instance, we have to measure the spectral lines of atoms (i.e. their...
