Lasers Spin Nanotube Yarn
NEWPORT NEWS, Va., Dec. 3, 2009 – Lasers now have been used to create the first practical macroscopic yarns from boron nitride fibers, opening the door for an array of applications from solar cells to stronger body armor. Researchers created a technique to synthesize high-quality boron-nitride nanotubes (BNNTs) that are highly crystalline and that have a small diameter.
Solar Impulse Aces 1st Flight
DÜBENDORF AIRFIELD, Switzerland, Dec. 3, 2009 – The first airplane designed to fly day and night without fuel, the Solar Impulse HB-SIA, left the ground for the first time today. The results of the ground tests conducted over the past few weeks to verify numerous parameters had been...
Atoms Fooled by Fake Field
GAITHERSBURG, Md., Dec. 2, 2009 -- For the first time, physicists have used laser light to create "synthetic magnetism," an exotic condition in which neutral atoms suddenly begin to behave as if they were charged particles interacting with a magnetic field – even though no such field...
QCL Output Power Boosted
EVANSTON, Ill., Dec. 2, 2009 -- An output power of 120 W was delivered by a single mid-infrared quantum cascade laser operating at room temperature, a breakthrough seen as important for future defense applications and nearly four times the output power recorded a year ago from a...
“Photonic machine gun” fires up supercomputer research
LONDON – The entanglement of photons is key to developing quantum computers and cryptography devices. However, understanding exactly what entanglement means is tricky, as is generating entangled photons at defined points in time. Researchers at Imperial...
Big research on tiny technologies
Dec 1, 2009 — IMEC is one busy research center. Headquartered in Leuven, Belgium, the independent research and development center focuses on nanoelectronics and nanotechnology, partnering with companies, universities and other research institutes. One example of...
Fiber laser reaches record length
BIRMINGHAM, UK – In a bid to push the boundaries of laser science, a team of scientists from the UK, Spain and Russia has built the longest-ever fiber laser cavity. The group’s aim was to find out just how long it could make a fiber laser cavity in which lasing with...
Getting to the electrochemical core makes for better materials science
NOTTINGHAM, UK – Scientists have, for the first time, probed the inner core of electrochemical interactions as they happen. The application of this new spectroelectrochemistry technique could lead to a more efficient and more intelligent design of new materials to...
Laser Avenger Destroys IEDs
HUNTSVILLE, Ala., Dec. 1, 2009 – A laser system mounted on an Avenger combat vehicle destroyed 50 improvised explosive devices (IEDs) similar to those used in war zones during tests in September by the Boeing Co. and the US Army.
Nanocavity brings optical tweezing down to size
SHANGHAI, China – An international team of researchers is taking steps to bridge the gap between nanophotonics and nanomechanics by harnessing the induced near-field force within a nanocavity. Yuchuan Jian at Fudan University and at Duke University in Durham,...
Nanotowers Fire Off Photons
WÜRZBURG, Germany, Dec. 1, 2009 – Nanotowers made of semiconducting material 'fire off' single photons in a targeted fashion, an ability needed for secure data transmission through quantum cryptography, said researchers at the University of Würzburg.
Synchronized flying in space makes for good detection
TEDDINGTON, UK – Researchers from the National Physical Laboratory (NPL) are using femtosecond laser combs and optical imaging features on multiple spacecraft with the idea of creating one large detector that will enhance Earth observation and exploration of the...
LHC Smashes Speed Record
GENEVA, Nov. 30, 2009 – CERN’s Large Hadron Collider (LHC) outside Geneva became the world’s highest-energy particle accelerator by accelerating its twin beams of protons to an energy of 1.18 TeV, breaking the previous record of 0.98 TeV held by Fermi Lab’s Tevatron...
Multibeam Lasers Emit in IR
CAMBRIDGE, Mass., Nov. 30, 2009 – An international team of applied scientists demonstrated compact, multibeam and multiwavelength lasers emitting in the infrared. Typically, lasers emit a single light beam of a well-defined wavelength; with their multibeam abilities, the new lasers...
Nanowire Transistors Realized
WEST LAFAYETTE, Ind., Nov. 30, 2009 – A new generation of ultrasmall transistors and more powerful computer chips using semiconducting nanowires are closer to reality after researchers at IBM, Purdue and UCLA learned how to make them with layers of materials that are sharply defined at...
Telling Tom Turkey from Tina
DRESDEN, Germany, Nov. 25, 2009 – A novel approach to classifying the gender of 6-week-old turkey poults could save millions of male chicks from being killed shortly after birth, according to Dr. Gerald Steiner and his team from the Dresden University of Technology. Their use of...
Virtual Brain Surgery
BALTIMORE, Nov. 24, 2009 – Jin U. Kang, an electrical engineer at Johns Hopkins University, has spent years tinkering with lasers and optical fiber – studying what happens when light strikes matter. Now, he has built a tool to help brain surgeons locate and get a clear look...
LHC: The Beams are Back
GENEVA, Nov. 23, 2009 – Particle beams are once again circulating in the Large Hadron Collider (LHC), 14 months after an electrical failure caused serious damage to the world’s most powerful particle accelerator, which straddles the borders of France and Switzerland and is...
Photoswitch Paralyzes Animals
WASHINGTON, D.C., Nov. 23, 2009 – An internal on-off “switch” that paralyzes animals when exposed to a beam of ultraviolet light has been developed by a team of scientists in Canada. The animals stay paralyzed even when the light is turned off. When exposed to ordinary light, the...
Opportunity in the Indian RE sector
Nov 20, 2009 — Now then, let's look at one other opportunity story in the Indian renewable energy (RE) sector. This time, it is Sunil Jain, COO of Greeninfra Ltd., who said that the total RE capacity was only 9 percent of the total Indian capacity. The race to...
QDs Improve Medical Imaging
GAITHERSBURG, Md., Nov. 19, 2009 – Changes in a living cell that take place over a long period of time are difficult to scrutinize and require high-spatial-resolution imaging. But new research now makes it possible to analyze activities that occur over hours or even days inside...
Light Moves Nanostructures
ITHACA, N.Y., Nov. 18, 2009 – With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 mW of power to move a silicon structure up to 12 nm. That’s enough to completely switch the optical properties of the structure from opaque to...
Complex Solar Surface Imaged
KATLENBURG-LINDAU, Germany, Nov. 17, 2009 – The most detailed images to date of the sun's grainy-looking surface were produced by the Sunrise balloon-borne telescope, a collaboration between the Max Planck Institute for Solar System Research (MPS) in Katlenburg-Lindau, Germany, and partners...
Mess-Free Graphene Growth
ITHACA, N.Y., Nov. 16, 2009 – A research team at Cornell University invented a simple, less expensive way to make graphene electrical devices by growing graphene -- one-atom-thick layers of carbon -- directly onto a silicon wafer.
Virtual Cloaking Unveiled
WASHINGTON, Nov. 16, 2009 – Researchers at Germany’s Karlsruhe Institute of Technology created a virtual visualization tool that shows what a partially or completely cloaked object would really look like. Even as an invisibility cloak hides an object, the cloak itself is...
