Image 1 - Scientists Create World’s Most Powerful X-ray Laser
2012-01-26 06:20:13

Creating and observing super-hot solid plasma could lead to a greater understanding of fusion processes. In two separate studies, the world´s most powerful X-ray laser has been used to build the first atomic X-ray laser pulse, as well as to superheat and control a clump of 2-million-degree matter. The atomic laser could be used to watch biological molecules at work, while the creation of hot dense matter could be used to understand the processes of nuclear fusion. Scientists...

Image 1 - Under The Electron Microscope – A 3-D Image Of An Individual Protein

The high resolution of Lawrence Berkeley National Laboratory´s Gang Ren When Gang Ren whirls the controls of his cryo-electron microscope, he compares it to fine-tuning the gearshift and brakes of a racing bicycle. But this machine at the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) is a bit more complex. It costs nearly $1.5 million, operates at the frigid temperature of liquid nitrogen, and it is allowing scientists to see what no one...

Research by UC Riverside-led team has potential applications in digital and infrared technologies A research team led by physicists at the University of California, Riverside has identified a property of "bilayer graphene" (BLG) that the researchers say is analogous to finding the Higgs boson in particle physics. Graphene, nature's thinnest elastic material, is a one-atom thick sheet of carbon atoms arranged in a hexagonal lattice. Because of graphene's planar and chicken wire-like...

Physicists Mimic Jupiter's Trojan Asteroids Inside Single Atom

[ Watch the Video ] Orbit of captured electron matches orbit of Jupiter's captured asteroids Rice University physicists have gone to extremes to prove that Isaac Newton's classical laws of motion can apply in the atomic world: They've built an accurate model of part of the solar system inside a single atom of potassium. In a new paper published this week in Physical Review Letters, Rice's team and collaborators at the Oak Ridge National Laboratory and the Vienna University of...

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. The findings, to be published this week in the journal Physical Review Letters, offer a more complete understanding of the mechanisms for electron transport in nanostructures at the atomic level. "We have been able to study some of the most complicated transport mechanisms that can arise up to the single atom level," says lead...

Breakthrough in coordinating electrons advances goal of quantum computing An international team of researchers including scientists at Princeton University have achieved a 100-fold increase in the ability to maintain control the spins of electrons in a solid material, a key step in the development of ultrafast quantum computers. Until recently, the best attempts at such control lasted for only a fraction of a second. But researchers Stephen Lyon and Alexei Tyryshkin have found a way to...

How Many Atoms Does It Take To Store A Memory Bit?
2012-01-13 09:46:22

Researchers at International Business Machines (IBM) have discovered how to store a bit of information in just 12 atoms, a process that usually requires the use of a million or more atoms. The technique, reported in the journal Science, is based on ferromagnetism and could allow for even smaller, faster and more energy-efficient devices in the future. “The chip industry will continue its pursuit of incremental scaling in semiconductor technology but, as components continue to...

University of California, Davis, researchers have proposed a radical new way of thinking about the chemical reactions between water and metal oxides, the most common minerals on Earth. Their work appears in the current issue of the journal Nature Materials. The new paradigm could lead to a better understanding of corrosion and how toxic minerals leach from rocks and soil. It could also help in the development of “green” technology: new types of batteries, for example, or...

The smallest wires ever developed in silicon - just one atom tall and four atoms wide - have been shown by a team of researchers from the University of New South Wales, Melbourne University and Purdue University to have the same current-carrying capability as copper wires. Experiments and atom-by-atom supercomputer models of the wires have found that the wires maintain a low capacity for resistance despite being more than 20 times thinner than conventional copper wires in microprocessors....

Silicon links shrink to atomic scale     The narrowest conducting wires in silicon ever produced are shown to have the same electrical current carrying capability as copper, as published in Science.     This means electrical interconnects in silicon can be shrunk to the atomic-scale without losing their functionality — Ohm's law holds true at the atomic-scale.     UNSW researchers will use these wires to address individual atoms —...
