Scientists Explore Ways To Synchronize Magnetic Spins For More Powerful Nanoscale Electronic Devices
2014-04-30 03:07:24

Brookhaven National Laboratory Scientists at the U.S. Department of Energy's Brookhaven National Laboratory are seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving antennas and other electronics. Their latest work, published in Nature Communications, shows that stacked nanoscale magnetic vortices separated by an extremely thin layer of copper can be driven to operate in unison, potentially producing a powerful...

Creating Nanowires Only Three Atoms Wide With An Electron Beam
2014-04-28 03:12:14

David Salisbury, Vanderbilt University Junhao Lin, a Vanderbilt University Ph.D. student and visiting scientist at Oak Ridge National Laboratory (ORNL), has found a way to use a finely focused beam of electrons to create some of the smallest wires ever made. The flexible metallic wires are only three atoms wide: One thousandth the width of the microscopic wires used to connect the transistors in today's integrated circuits. Lin's achievement is described in an article published online...

When chemist Tehshik Yoon looks out his office window, he sees a source of energy to drive chemical reactions. Plants “learned” to synthesize chemicals with sunlight eons ago; Yoon came to the field a bit more recently. But this week, in the journal Science, he and three collaborators detail a way to use sunlight and two catalysts to create molecules that are difficult to make with conventional techniques — a finding that may eventually have implications for drug making and materials...

Exotic Materials Study Could Lead To Advanced Electronic Devices

redOrbit Staff & Wire Reports - Your Universe Online In an attempt to help scale down the size of electronic devices to atomic dimensions, researchers from Cornell University and the Brookhaven National Laboratory have demonstrated how to convert a particular transition metal oxide from a metal to an insulator by reducing its size to less than one nanometer thick. In research currently appearing online and scheduled for publication in the May edition of the journal Nature...

CEBAF Accelerator Achieves 12 GeV Commissioning Milestone
2014-04-15 12:09:23

Jefferson Lab Late on April 1, the crown jewel of the Department of Energy's Thomas Jefferson National Accelerator Facility (“Jefferson Lab”) sparkled its way into a new era. Following an upgrade of the Continuous Electron Beam Accelerator Facility, the CEBAF accelerator delivered the highest-energy electron beams it has ever produced into a target in an experimental hall, recording the first data of the 12 GeV era. The machine sent electrons around the racetrack three times (known as...

Quantum Computing Advances At MIT - Trapping Rubidium Atoms In A Lattice Of Light
2014-04-11 04:29:35

redOrbit Staff & Wire Reports - Your Universe Online Scientists at MIT and Harvard University have developed a light lattice that traps atoms, a technique they say could aid in the creation of powerful quantum computing systems. The researchers used a laser to place individual atoms of the metal rubidium near the surface of a lattice of light, allowing them to couple a lone atom with a single photon, or light particle. The system allows both the atom and photon to switch the quantum...

Drexel University researchers are turning some of the basic tenets of chemistry and physics upside down to cut a trail toward the discovery of a new set of materials. They’re called “polar metals” and, according to many of the scientific principles that govern the behavior of atoms, they probably shouldn’t exist. James Rondinelli, PhD, a professor in the College of Engineering, and Danilo Puggioni, PhD, a postdoctoral researcher in the College, have shed light on this rare breed of...

Schematic of the detector: the metamaterial couples the incident light to the semiconductor, and then it can be converted into an electric signal
2014-03-30 06:26:20

Florian Aigner, Vienna University of Technology A new, extremely thin kind of light detector was created at Vienna University of Technology. Two very different technologies were combined for the first time: metamaterials and quantum cascade structures. Subtle interactions of electrons and light make them so valuable for technology: ultra-thin systems of semiconductor layers can turn electrical voltage into light. But they can also be used the other way around and serve as light...

vortex multiplication in a quantum fluid
2014-03-26 03:00:39

University of Cambridge Researchers have developed a new mathematical framework capable of describing motions in superfluids – low temperature fluids that exhibit classical as well as quantum behavior. The framework was used to lift the veil of mystery surrounding strange objects in superfluid helium (detected ten years ago at Brown University). The study, conducted by an international collaboration of researchers from the UK, Russia and France is published today in the journal...

Diamonds Help Speed Up Spintronics
2014-03-26 04:49:49

Lee Rannals for redOrbit.com - Your Universe Online Researchers from Ohio State University have demonstrated for the first time that information can flow through a diamond wire. Scientists are working to develop “spintronics” in order to make computers simultaneously faster and more powerful. Spin could be used to help transmit data in computer circuits, and the latest research shows just how viable of an option diamonds could be. The team wrote in the journal Nature...

The Cathode Ray Tube, which has internal or external means to accelerate and deflect electron beams, is a vacuum tube containing an electron gun and a fluorescent screen. The electron beams that are deflected are used to create images in the form of light emitted from the fluorescent screen. The CRT works by using an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Ferdinand Braun is credited with the first CRT in 1897. It can also be known as the Braun tube....

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
