Images of Atomic Spin Captured
ATHENS, Ohio, April 28, 2010 — A custom-built microscope with an iron-coated tip to manipulate cobalt atoms on a plate of manganese has allowed physicists at Ohio University and the University of Hamburg in Germany to image, for the first time, a quantum mechanical property of electrons known as atomic spin.
Lasers Promising for Chemical Decontamination
WASHINGTON, DC, April 27, 2010 — The Department of Homeland Security is funding research at Idaho National Laboratory that involves using lasers to decontaminate chemical explosion sites. Most preferred methods today employ other chemicals, like bleach solutions, which can be...
Lensless Microscope Made for Telemedicine
LOS ANGELES, April 27, 2010 — Aydogan Ozcan, whose invention of a novel lensless imaging technology for telemedicine could radically transform global health care, has now taken his work a step further. The University of California, Los Angeles engineer has created a miniature...
Novel Metamaterial Responds to Visible Light
PASADENA, Calif., April 27, 2010 — An artificial optical material with a three-dimensional structure has been engineered to bend light in the “wrong” direction from what normally would be expected, irrespective of the angle of the approaching light. This new type of negative-index...
IBM Creates World’s Smallest 3-D Map
ZURICH and SAN JOSE, Calif. April 26, 2010 — Scientists have created a 3-D map of the earth so small that 1000 of them could fit on one grain of salt. They accomplished this through a breakthrough technique that uses a tiny, silicon tip with a sharp apex – 100,000 times smaller than a...
Synthetic Diamonds Key to Laser Discoveries
SYDNEY, Australia, April 26, 2010 — Richard Mildren, associate professor at the Macquarie University Photonics Research Center in Sydney, and colleagues discovered it was possible to generate a coherent laser beam from man-made diamond in late 2008. Now, they have demonstrated diamond...
Microreactors Advance Solar Cells
CORVALLIS, Ore., April 23, 2010 — A new technology that uses continuous flow microreactors to produce thin film absorbers for solar cells could significantly reduce the cost of solar energy devices and reduce material waste, according to engineers from Oregon State University and...
Plastic Lab-on-a-Chip Curbs Clots
MUNICH, Germany, April 23, 2010 — A plastic lab-on-a-chip system is being developed for fast and easy testing of thrombosis, or blood clots. An EU project that involves ten research institutes and high tech firms in eight European countries, called DVT-IMP, is developing the system...
SDO Unveils Images of ‘First Light’
PALO ALTO, Calif., April 23, 2010 — Spectacular “first light” images and data from three state-of-the art instruments on NASA’s Solar Dynamics Observatory (SDO) were unveiled this week. The SDO spacecraft was launched aboard a United Launch Alliance Atlas V rocket...
Correcting Vision Without Surgery
BARCELONA, Spain, April 22, 2010 — There is now a contact lens that is capable of correcting mild to moderate vision defects without surgery. This innovation has earned Jaume Pauné, a graduate of the master’s degree program at UPC (Universitat Politècnica de...
OCT Diagnoses Shaken Baby Syndrome
LOS ANGELES, April 22, 2010 — Ophthalmologists examining infants for possible shaken baby syndrome (SBS) found that a handheld spectral domain optical coherence tomography (SD-OCT) device provided high-resolution images of the retina and the vitreoretinal interface in infants...
Spanish University Wins Nanotech PV Project
CASTELLÓ, Spain, April 22, 2010 — After responding to a call for proposals, a research group led by Juan Bisquert at Universitat Jaume I of Castelló has won the bid for a scientific and technological research project on new types of solar cells based on nanotechnologies....
A Step Towards Quantum Computing
CARDIFF, Wales, April 21, 2010 — Physicists have discovered properties of hybrid light-matter particles, existing in the solid state matrix, which could one day lead to faster and more efficient computers and telecommunications. A team from Cardiff University’s School of...
HRL Designated Historical Laser Site
MALIBU, Calif., May 16, 2010 — HRL Laboratories LLC, formerly Hughes Research Laboratories, will be designated a Physics Historical Site by the American Physical Society (APS) as the location where the first working laser was demonstrated 50 years ago. HRL will be recognized...
Scanning Probe Microscope Accelerated
SAARBRÜCKEN, Germany, April 20, 2010 — For more than twenty years, the scanning force microscope has been employed in research and industry. Its enormous resolution has triggered many applications in nanotechnology. There is, however, a disadvantage – the low image rate...
Instrument Pulls on Atom’s Chain
GAITHERSBURG, Md., April 19, 2010 — In a recent experiment researchers demonstrated a tug-of-war at the atomic scale. The group, from the National Institute of Standards and Technology (NIST), has built an ultra-stable instrument for tugging on chains of atoms, an instrument that can...
Surveillance Applications for Iris Recognition
DALLAS, April 19, 2010 — Researchers are expanding new miniature camera technology for military and security uses so soldiers can track combatants in dark caves or urban alleys, and security officials can unobtrusively identify a subject from an iris scan. The two new...
China Champions LED Tunnel Lighting
MONTREAL, April 16, 2010 — LED-based tunnel lighting for two new highway tunnels in central China is saving up to 60 percent in energy consumption and related costs over fixtures built with traditional light sources. Utilizing Luxeon Rebel LEDs from Philips Lumileds, the 3900...
Imaging a Heart’s First Beat
HOUSTON, April 16, 2010 — Through high-resolution, non-invasive imaging, scientists are documenting the formation of the mammalian heart and are capturing video of the embryonic heart before it begins beating. Kirill Larin, assistant professor of biomedical engineering in...
Method Recovers Pricey Nanoparticles
BRISTOL, England, April 16, 2010 — Ounce for ounce nanoparticles can be more precious than gold, making a new-found method that recovers, recycles and reuses nanoparticles invaluable. Solar panels, flexible displays, and other futuristic electronics made with nanoparticles may become...
NSF-Supported Center Moves to Houston
HOUSTON, April 16, 2010 — The National Center for Airborne Laser Mapping (NCALM), supported by the National Science Foundation, has relocated operations to the University of Houston (UH) from the University of Florida. Researchers with the National Center for Airborne Laser...
Closing in on Carbon Solar Cells
BLOOMINGTON, Ind., April 15, 2010 — By attaching what amounts to a 3-D bramble patch to each side of a carbon sheet, scientists say they were able to dissolve sheets containing as many as 168 carbon atoms to make large stable graphene sheets available for light collection. "Our...
