Research & Technology News
Postage-stamp-sized Displays Move Closer
ANN ARBOR, Mich., Oct. 14, 2010 — University of Michigan scientists using AFOSR-funding have created the smallest pixels available that will enable LED, projected and wearable displays to be more energy efficient with more light manipulation possible and all on a display that may eventually be as small as a postage stamp. Schematic of color filters made of Plasmonic nanoresonators. (Image: L. Jay Guo, University of Michigan) This latest nanostructuring technology for the Air Force developed by Dr. Jay Guo, associate...
Altered Heart Cells Controlled with Light
BONN, Germany, Oct. 13, 2010 — Using a method called photostimulation, scientists at the University of Bonn have altered cardiac muscle cells to make them controllable with light. They were able to use directed blue light to cause conditions such as arrhythmia in genetically...
IR Laser Pulses ID Regenerative Drugs
CAMBRIDGE, Mass., Oct., 12, 2010 — Using a new laser surgery technique, MIT engineers have successfully delivered drugs that regenerate nerve cells in living animals. Scientists have long sought the ability to regenerate nerve cells, or neurons, which could offer a new way to treat...
Artificial White Light is Eye-friendly
WARSAW, Oct. 8, 2010 — A newly discovered class of organic substances that emit white light with a continuous spectrum is providing experimental evidence that only single component luminophore will be necessary to construct eye-friendly light sources and displays. ...
Laser Light Could Impact Drug Delivery
KINGSTON, Ontario, Oct. 8, 2010 — Researchers at Queen’s University have discovered how molecules in glass or plastic are able to move when exposed to light from a laser. The findings could one day be used to facilitate medicinal drug distribution by allowing doctors to...
Optical Sensor Used to Research Synthetic Fuels
WEST LAFAYETTE, Ind., Oct. 7, 2010 — Using an optical sensor to decode laser light that measures the temperature and composition of broken down biomass, or gasifiers, researchers at Purdue University are hoping to learn about the scientific foundations of synthetic fuel with the hope...
Plasmonic Nanobubbles Kill Cancer Cells
HOUSTON, Oct. 7, 2010 — Plasmonic Nanobubbles Kill Cancer Cells HOUSTON, Oct. 6, 2010 — Rice Plasmonic nanobubbles, generated around gold nanoparticles with a laser pulse, can detect and destroy cancer cells in vivo by creating tiny, shiny vapor bubbles that reveal...
Horizontally Grown Nanowires Yield ‘NanoLEDs’
GAITHERSBURG, Md., Oct. 6, 2010 — While refining their novel method for making nanoscale wires, chemists at the National Institute of Standards and Technology (NIST) discovered an unexpected bonus — a new way to create nanowires that produce light similar to that from LEDs....
Land-locked Laser Burns Boat Across Potomac
DAHLGREN, Va., Oct. 6, 2010 — Defense contractor Northrop Grumman Corp. reports its maritime laser system now shows "higher lethality" at longer ranges, after a system test resulted in several laser burns through small sections of a boat located across the Potomac River. The...
NoblePeak Vision Assets to be Liquidated
WAKEFIELD, Mass., Oct. 4 — NoblePeak Vision, a once-promising developer of camera cores that integrate germanium photodetectors with silicon circuits, will see its assets liquidated on Nov. 5 to pay off creditors, the company's certified public accountant announced this week....
Photon Color Barrier Broken in Fiber
EUGENE, Ore., Oct. 6, 2010 — The color of single photons in a fiber optic cable has been changed for the first time. The laser-tweaked feat could be a quantum step forward for transferring and receiving high volumes of secured data for future generations of the Internet.
Ultrafast Mid-IR Laser Scalpel Leaves Tiny Scars
TORONTO, Oct. 6, 2010, — Ultrafast Mid-IR Laser Scalpel Leaves Tiny Scars TORONTO, Oct. 6, 2010, — A new laser technique that could significantly reduce scarring after surgery has been discovered by researchers at The Hospital for Sick Children (SickKids) and the...
Bridgelux Adding Green Jobs in Calif.
LIVERMORE, Calif., Oct. 5, 2010 — LED lighting technologies and solutions manufacturer Bridgelux Inc. announced the dedication of its new headquarters in Livermore, and its plans for the addition of California-based green jobs as the market for energy-efficient LED lighting...
Graphene Pioneers Share Physics Nobel
STOCKHOLM, Oct. 5, 2010 — Two Russian expatriates who discovered graphene — the thinnest and strongest form of carbon known — were honored Tuesday with the 2010 Nobel Prize in Physics by the Royal Swedish Academy of Sciences.
A better limiter for laser light
LITTLE ROCK, Ark. – Fifty years after the birth of the laser, there may be better protection against the light fantastic, reports a team of researchers. They have found that nanographene, a form of carbon that comes in single atomic layers, might be the right choice...
A notch above for single nanoparticle detection
NEW YORK – Working in the field of single nanoparticle detection, researchers have demonstrated strong optical coupling between an on-chip notched microring resonator and a nanoparticle in the notch. “Recently, it was found that the electromagnetic modes...
Beam control system to help laser weapon protect soldiers
ALBUQUERQUE, N.M. – The High Energy Laser Technology Demonstrator is continuing on track to become the centerpiece of the US Army’s laser-based defense capabilities. The project, which includes components from Boeing Defense, Space and Security of St. Louis and...
Controlling a deformable mirror with light
SOPHIA ANTIPOLIS, France – Adaptive optics are likely to get a boost through new technology using light instead of electricity to control a deformable mirror (DM) that comes with a continuous membrane rather than segmented pixels. The technology, developed at Institut...
Laser breakthrough could soon enable 1-TB optical storage
SENDAI, Japan – Numerous research labs are looking for ways to increase the amount of information one can store on a CD-ROM or related optical disc, but the equipment needed to push past the boundaries of Blu-ray technology is exceedingly large and expensive....
Nanoneedle Delivers QDs to Cells
CHAMPAIGN, Ill., Oct. 4, 2010 — Getting an inside look at the center of a cell can be as easy as a needle prick, thanks to University of Illinois researchers who have developed a tiny needle to deliver a shot right to a cell’s nucleus. University of Illinois researchers...
Terahertz detection at a distance
TROY, N.Y. – When it comes to safe screening and detection, terahertz imaging offers considerable advantages but one major drawback. Terahertz waves occupy a large segment of the electromagnetic spectrum between the infrared and microwave bands and can provide...
UNL Gains Grant to Expand Laser Research
LINCOLN, Neb., Oct. 4, 2010 — The University of Nebraska-Lincoln has received nearly $2 million in federal stimulus funds from the National Science Foundation for renovations to expand its high-power laser research capabilities. The grant from NSF's Academic Research...
Beetle Scales Could Help Speed Computers
SALT LAKE CITY, Oct. 1, 2010 — Research that began as a high school science fair project involving a shiny Brazilian beetle may ultimately help advance the pursuit of ultrafast computers that manipulate light rather than electricity. Brigham Young University physics major Lauren...
Cluster to boost silicon photonics transfer
Oct 1, 2010 — A number of European research and development project consortia have clustered to facilitate the transfer of silicon photonics technology from the research stage to industrial development. The 10 projects – called Boom, Historic, Helios,...
Look, Ma! No hands!
Oct 1, 2010 — I watch in amazement as the woman in the television commercial pushes a button on her dashboard and sits back, gleeful, while her car parks all by itself. And not a simple diagonal parking job, mind you, but the hair-raising parallel kind. The kind...
