Rainbow-Trapping Scientist Now Strives to Slow Light Waves Even Further
April 12, 2011 — An electrical engineer who previously demonstrated experimentally the "rainbow trapping effect" -- a phenomenon that could boost optical data storage and communications -- is now working to capture ... > full story -
Controlled Production of Nanometric Drops
April 12, 2011 — When a drop falls on a lotus flower it remains on the surface without wetting it. This is due, firstly, to the chemical components of the leaves of this plant, which are hydrophobic and therefore ... > full story -
DNA Stretching: New Technique to Detect Illnesses
April 5, 2011 — Scientists are making DNA sequences being passed through nanochannels a thousand times thinner than a human hair to the point that they take on the form of diminutive spaghetti. DNA stretching ... > full story -
First Macro-Scale Thin-Film Solid-Oxide Fuel Cell: Strong, Nanostructured Membrane Enables Scaling for Clean-Energy Applications
April 4, 2011 — Materials scientists have demonstrated the first macro-scale thin-film solid-oxide fuel cell. While SOFCs have previously worked at the micro-scale, this is the first time any research group has ... > full story -
Self-Cooling Observed in Graphene Elctronics
April 3, 2011 — With the first observation of thermoelectric effects at graphene contacts, researchers have found that graphene transistors have a nanoscale cooling effect that reduces their temperature. Using an ... > full story -
New Tool Makes Programs More Efficient Without Sacrificing Safety Functions
March 31, 2011 — Computer programs are incorporating more and more safety features to protect users, but those features can also slow the programs down by 1,000 percent or more. Researchers have developed a software ... > full story -
Swedish Invention Simplifies Home Diagnostics
March 24, 2011 — Advances in medical diagnostic technology may one day enable individuals to perform preliminary medical diagnoses themselves, in their own home, in the ... > full story -
New Blood Analysis Chip Could Lead to Disease Diagnosis in Minutes
March 18, 2011 — A major milestone in microfluidics could soon lead to stand-alone, self-powered chips that can diagnose diseases within minutes. The device is able to process whole blood samples without the use of ... > full story -
Tiny 'on-Chip Detectors' Count Individual Photons
March 17, 2011 — A team of researchers has integrated tiny detectors capable of counting individual photons on computer chips. These detectors, called "single-photon avalanche diodes," act like mini Geiger counters, ... > full story -
'Pruned' Microchips Are Faster, Smaller, More Energy-Efficient
March 16, 2011 — Computing experts from the United States, Switzerland and Singapore have unveiled a technique for doubling the efficiency of computer chips by trimming away rarely used circuits. While these "pruned" ... > full story
