Unique Properties of Graphene Lead to a New Paradigm for Low-Power Telecommunications
July 15, 2012 — Engineers have demonstrated remarkable optical nonlinear behavior of graphene that may lead to broad applications in optical interconnects and low-power photonic integrated circuits. The researchers ... > full story -
Physicists Invent 'Spintronic' LED
July 12, 2012 — University of Utah physicists invented a new “spintronic” organic light-emitting diode that promises to be brighter, cheaper and more environmentally friendly than the kinds of LEDs now ... > full story -
Quantum Computing, No Cooling Required: Room-Temperature Quantum Bits Store Data for Nearly Two Seconds
July 3, 2012 — Using a pair of impurities in ultra-pure, laboratory-grown diamonds, researchers have created room-temperature quantum bits, and store information in them for nearly two seconds -- an increase of ... > full story -
First Photo of Shadow of Single Atom
July 3, 2012 — Scientists have captured the first image of the shadow of a single atom. They trapped single atomic ions of the element ytterbium and exposed them to a specific frequency of light. Under this light ... > full story -
New Technique Controls Graphite to Graphene Transition
June 29, 2012 — Physicists have found a way to systematically study and control the transition of graphite, the “lead” found in pencils, to graphene, one of the strongest, lightest and most conductive ... > full story -
Structure of New Superhard Form of Carbon Established
June 26, 2012 — Researchers have established the structure of a new form of carbon. The team used a novel computational method to demonstrate that the properties of what had previously been thought to be only a ... > full story -
Scientists Spark New Interest in the Century-Old Edison Battery
June 26, 2012 — Scientists have dramatically improved the performance of Thomas Edison's nickel-iron battery. The enhanced device could be used in electric vehicles, much as Edison originally ... > full story -
Bringing Down the Cost of Microbial Fuel Cells
June 23, 2012 — A new catalyst material could dramatically reduce the cost of producing microbial fuel ... > full story -
Researchers Tune the Strain in Graphene Drumheads to Create Quantum Dots
June 21, 2012 — Researchers have shown that they can tune the strain in graphene suspended like drumheads over microscopic holes in a substrate of silicon oxide using the tip of an advanced scanning probe microscope ... > full story -
Graphene Research: Trapping Light in a Carbon Net
June 21, 2012 — Graphene, an ordered monolayer of carbon, is the thinnest substance known, and yet has extraordinary mechanical strength. A new study shows that its two-dimensional network of atoms can even trap ... > full story
