Quantum dot-based image sensors: A picture of the future?
MENLO PARK, Calif. – After operating in complete secrecy for the past three years, InVisage Technologies Inc. has revealed the reason behind its clandestine behavior: the development of a new type of image sensor material that promises to deliver four times better image quality than traditional silicon-based sensors. Edward “Ted” Sargent, chief technology officer and lead researcher behind the project, said that the company’s QuantumFilm technology will be the first to combine “great ...
Quantum sensor sets new limits
BATON ROUGE, La. – Researchers at Louisiana State University (LSU) are taking advantage of the quantum properties of light to design the world’s most sensitive optical interferometer. Optical interferometers are used in a vast range of applications, including...
STEM technique maps all the atoms in any molecule
OAK RIDGE, Tenn. – Transmission electron microscopy (TEM) is a technique that should, in theory, facilitate direct imaging and chemical identification of each and every atom in a material that has an unspecified three-dimensional structure. This is especially true...
Superwicking with silicon
ROCHESTER, N.Y. – Because most computer chips and transistors are made of the semiconductor silicon, the element is key to the microelectronics industry. A serious barrier with silicon, however, is keeping components cool. Until now, computer chips have been...
X-ray, meet optical control …
BERKELEY, Calif. – Researchers have shown that they can control matter directly with intense x-ray beams and can use one beam to control another. The experiments could open the door to new and interesting ways to use x-rays, said Thornton E. “Ernie” Glover...

Getting to the ‘Core’ of Nanoparticles
GAITHERSBURG, Md., June 3, 2010 — Researchers at the National Institute of Standards and Technology (NIST) have discovered a mysterious nanoparticle that could have potential uses both as a the basis of better data storage systems and in biological applications such as hyperthermia...
Nature’s ’Light Switch’ Decoded
UPTON, N.Y., June 2, 2010 — Scientists at the US Department of Energy’s (DoE) Brookhaven National Laboratory and collaborators at the University of Wisconsin, Madison, have deciphered the structure of a molecular ‘switch’ much like the one plants use to sense...
Plasmonic Amplifier Demonstrated
REYKJAVIK, Iceland, June 2, 2010 — In an important breakthrough in the field of plasmonics, researchers led by Kristjan Leosson and Malte Gather of the University of Iceland have demonstrated net optical amplification in a plasmonic waveguide. Optical amplification is the only...
Tiny Glass Slivers Conduct Current
ANN ARBOR, Mich., June 2, 2010 — Tiny glass slivers made by a laser have been found to conduct electrical currents nondestructively. In the macroscale world, materials called conductors effectively transmit electricity and materials called insulators or dielectrics don't,...
Chiral Gold Nanocluster Demystified
JYVÄSKYLÄ, Finland, June 1, 2010 — After ten years, the mystery of the structural, electronic and optical properties of a chiral gold nanocluster, has finally been resolved. Researchers at the Department of Chemistry and Nanoscience Center (NSC) of the University of...
NIRCam Set for NASA Tests
GREENBELT, Md., June 1, 2010 — A test unit for the Near Infrared Camera (NIRCam) instrument that will fly aboard the James Webb Space Telescope has arrived at NASA’s Goddard Space Flight Center and has been placed in a clean room for a year’s worth of testing. The...
Photonics in Spain: Open for business
CASTELLDEFELS, Spain – “Several industrial sectors related to photonics are growing in Spain, especially those related to energy efficiency and health,” said Silvia Carrasco, knowledge and technology transfer director at ICFO – The Institute of Photonic...

HOUSTON, May 28, 2010 — Scientists from four US universities have created a way to use Rice University’s light-activated nanoshells as building blocks for 2-D and 3-D structures that could find use in chemical sensors, nanolasers and bizarre light-absorbing...
Visually Guided Laser Treats Arrhythmia
DALLAS, May 28, 2010 — A new treatment known as a visually-guided laser balloon catheter successfully interrupted abnormal electrical pulses in patients and pigs with intermittent, irregular heartbeats, has been reported by the American Heart Association. Severe cases of...
Remote Sensing Tracks Invasive Trees
WESLACO, Texas, May 27, 2010 — A team of Agricultural Research Service (ARS) scientists has refined remote sensing tools for identifying invasive Ashe juniper shrubs and trees in central Texas and nearby regions. These findings can help rangeland managers determine the extent and...
Spinning Nanofibers Like Cotton Candy
CAMBRIDGE, Mass., May 27, 2010 — A new patent-pending invention literally spins, stretches and pushes out 100 nanometer-diameter polymer-based threads using a rotating drum and nozzle – much like a cotton candy machine. According to lead author of study, Mohammad Reza...
Mining for Quantum Dots
HOUSTON, May 26, 2010 — Graphene, the one-atom-thick, honeycomb-like form of carbon, is the material of choice for physicists on the cutting edge of materials science. Researchers mentored by Boris Yakobson, a Rice professor of mechanical engineering and materials science...
NanoWizard Studies 5300-Year-Old Iceman
BERLIN, May 26, 2010 — Studying historical artifacts is always of interest and when the latest nanotechnology instrumentation is applied to the analysis of ancient materials, the interest rises to a higher level. In the Department of Earth and Environmental Sciences at...
‘Microlens’ Enhances IR Satellite Imaging
Troy, N.Y., May 25, 2010 — Researchers from Rensselaer Polytechnic Institute have developed a new nanotechnology-based ’microlens’ that uses gold to boost the strength of infrared imaging and could lead to a new generation of ultra-powerful satellite cameras and...
