Quantum dots: get your free samples here!
A company spun out from the UK's University of Manchester has become the first in the world to produce and ship multi-gram quantities of quantum dots - and has launched a unique 'Free Evaluation Samples' program throughout the EU and UK. Using a patented process, Nanoco Ltd is not only able to... view more (2002-10-23)

Mechanical motion used to 'spin' atoms in a gas
For the first time, mechanical motion has been used to make atoms in a gas "spin," scientists at the National Institute of Standards and Technology (NIST) report.   view more (2006-12-11)

Physics World Digest: March 2002 edition
Special issue: women in physics When the astronomer Jocelyn Bell Burnell was a physics student at Glasgow in the 1960s, she was greeted by a barrage of wolf whistles and foot stamping every time she walked into the lecture theatre. Bell Burnell was, quite simply, the only woman in a class of 50... view more (2002-03-01)

LASIK works well, according to long-term study of highly myopic patients
Laser surgery to correct vision problems has been in use since the early 1990s. Photorefractive Keratotomy (PRK) is typically used to correct low to moderate myopia, while laser in-situ keratomileusis (LASIK) is preferred for high myopia corrections.   view more (2007-12-28)

Impetus for TESLA
"DESY welcomes the rapid and trend-setting statement of the Federal Government on the large-scale research facilities and sees it as a tremendous chance for TESLA," said the Chairman of the DESY Directorate, Professor Albrecht Wagner in a first reaction. "The possibility to realize the TESLA X-ray... view more (2003-02-05)

Quantum Secrets of Photosynthesis Revealed
Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency.   view more (2007-04-13)

By straddling twin molecules, Sandia physicist obtains unique view of their breakup
Imagine you are standing, John Wayne style, on the backs of two runaway horses pulling a stagecoach. You try to bring the horses to a stop but instead the harnesses break, the horses separate, and an unlucky passenger gets thrown from the stage.   view more (2006-01-20)

New evidence for organic compounds in deep space
The mysterious spectral bands in the infrared of interstellar gas clouds in deep space originate from organic compounds. Research by the Nijmegen physicist Hans Piest confirms this. He has provided new experimental evidence for this almost 30-year-old problem in astronomy. Each molecule has... view more (2002-04-18)

Laser-trapping of rare element gets unexpected assist
Argonne researchers have successfully laser-cooled and trapped atoms of radium - the first time this rare element has been captured in a magneto-optical trap - with an assist from an unexpected source.   view more (2007-05-02)

Long-distance record -- 'Quantum keys' sent 200 kilometers
Particles of light serving as "quantum keys"-the latest in encryption technology-have been sent over a record-setting 200-kilometer fiber-optic link by researchers from the National Institute of Standards and Technology (NIST), NTT Corp. in Japan, and Stanford University.   view more (2007-06-04)

Unique Quantum Effect Found in Silicon Nanocrystals
Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), collaborating with Innovalight, Inc., have shown that a new and important effect called Multiple Exciton Generation (MEG) occurs efficiently in silicon nanocrystals. MEG results in the formation of more... view more (2007-07-26)

Nanocomposite labeled cancer cells can be targeted and destroyed using lasers
A nanocomposite particle can be constructed so that it has a mix of properties that would not otherwise happen in nature. By combining an organic matrix with metallic clusters that can absorb light, it is possible to incorporate such particles into cells and then destroy those targeted cells with a... view more (2007-05-21)

Ultra-Intense Laser Blast Creates True 'Black Metal'
"Black gold" is not just an expression anymore. Scientists at the University of Rochester have created a way to change the properties of almost any metal to render it, literally, black.   view more (2006-11-22)

Computer vision for the blind
The white cane used by the blind as a travel aid may be universal, but it is not always adequate when it comes to pedestrian crossings. Although some crossings make a sound when it is safe to cross, many do not, and it is at these crossings that the blind need to know when the green man is showing.... view more (2002-08-15)

Nano technique allows precise injection of living cells
Specialized pulsed lasers have been used to inject individual cells with a variety of materials, but little is known about how this type of injection might affect living cells.   view more (2007-06-18)

Soap, DNA and semiconductors
How can studying soap lead to better methods for transporting drugs around the body? Where’s the link between semiconductors and DNA and how can statistical physics reveal how ecosystems evolve? Find out at the Institute of Physics Condensed Matter and Materials Physics (CMMP) Conference... view more (2000-12-13)

Harvard University engineers demonstrate laser nanoantenna
Engineers and applied scientists from Harvard University have demonstrated a new photonic device with a wide range of potential commercial applications, including dramatically higher capacity for optical data storage.   view more (2006-09-07)

What do Racquel Welch and quantum physics have in common?
The study aims to delve into a 'void' or empty space in which atoms move, which has a large intrinsic energy density known as zero-point energy   view more (2006-06-30)

'Tunable' network features coordinated frequency combs
A super stable fiber-optic network that can be tuned across a range of visible and near-infrared frequencies while synchronizing the oscillations of light waves from different sources has been demonstrated at the National Institute of Standards and Technology (NIST).   view more (2007-05-14)

Argonne scientists use lasers to align molecules
Protein crystallographers have only scratched the surface of the human proteins important for drug interactions because of difficulties crystallizing the molecules for synchrotron x-ray diffraction.   view more (2008-05-14)

NIST laser-based method cleans up grubby nanotubes
Before carbon nanotubes can fulfill their promise as ultrastrong fibers, electrical wires in molecular devices, or hydrogen storage components for fuel cells, better methods are needed for purifying raw nanotube materials.   view more (2006-12-26)

Delft University of Technology shines light on atomic transistor
Researchers from Delft University of Technology and the FOM Foundation (Fundamental Research on Matter) have successfully measured transport through a single atom in a transistor.   view more (2006-11-27)

Astronomers use laser to take clearest images of the center of the Milky Way
UCLA astronomers and colleagues have taken the first clear picture of the center of our Milky Way galaxy, including the area surrounding the supermassive black hole, using a new laser virtual star at the W.M. Keck observatory in Hawaii.   view more (2005-12-21)

Laser cancer treatment and Martian imaging
Can laser light be used to treat cancer patients? Why is the search for Martian water so important? These questions may appear to be unconnected, but they actually have more in common than you might think. Both subjects will be tackled at free public talks held at Cardiff International Arena on... view more (2002-08-21)

Lasers Penetrate Cancer's Gene Secrets
LIGHT SABRES and phaser guns may be the stuff of science fiction, but laser technology has brought an important step forward in our present-day understanding of cancer, a study reveals this week.* By using miniature lasers to probe pancreatic tumours, Cancer Research UK scientists have implicated... view more (2002-07-04)
