Lasers in car manufacture
Lasers play a key role in modern production - for such tasks as cutting sheet metal to size, welding containers and trimming circuit . But their potential is far from exhausted. The automobile industry is playing a pioneering role in the introduction of new laser types and machining processes. The... view more (1999-07-01)

OHSU eye doctor says laser surgery safer than contacts
Traditional assumptions have held that contact lenses are safer than laser surgery to correct vision problems.   view more (2006-10-10)

Tiny avalanche photodiodes target bioterrorism agents
After the anthrax attacks in the United States in 2001 the threat of a larger and more deadly bioterrorism attack - perhaps from smallpox, plague or tularemia - became very real. But the ability to detect such biological agents and rapidly contain an attack is still being developed.   view more (2005-09-14)

'Racetrack' for fast electrons in semiconductor structures
In order to realize the electrical units of voltage, resistance and current with highest accuracy quantum effects in nano-circuits are nowadays used. Important prerequisites are extremely pure semiconductor layers where high-mobile electrons move through the crystal without collision with residual... view more (2008-08-29)

Physicists exploit ultra-cold gases to measure ultra-small magnetic fields
Capturing the coldest atoms in the universe within the confines of a laser beam, University of California, Berkeley, physicists have made a device that can map magnetic fields more precisely than ever before.   view more (2007-05-22)

Code for unbreakable quantum encryption generated at record speed over fiber
Raw code for 'unbreakable' encryption, based on the principles of quantum physics, has been generated at record speed over optical fiber at the Commerce Department's National Institute of Standards and Technology (NIST).   view more (2006-04-19)

Stengthening the glow of nanotube luminescence
Nanotubes are the poster children of the nanotechnology revolution. These tiny carbon tubes - less than 1/50,000 the diameter of a human hair - possess novel properties that have researchers excitedly exploring dozens of potential applications ranging from transistors to space elevators.   view more (2005-11-15)

Miniature Pyramids
The production and characterisation of semiconductor nanostructures Vienna (Austrian Science Fund) - Electronic components, such as transistors on computer chips, are increasingly becoming smaller, while their performance capabilities are growing. It is expected that the dimensions of such... view more (2001-09-27)

New quantum state: two electrons trapped in an excited atom
Researchers from Universitat Autònoma de Barcelona and the University of Salamanca have discovered a method to generate a new quantum phenomenon which had never been explored until now: simultaneous trapping of two particules between two excited energy states. The research, reported in... view more (2002-01-23)

Laser analyses fuel flame
In a project from the Technology Foundation STW, researcher Roger Evertsen has introduced a new method for measuring the composition of fuel flames. The technique makes use of laser light and is not only quick but also extremely sensitive.   view more (2002-11-15)

McCormick Researchers Take Step Toward Creating Quantum Computers
For now, full-fledged quantum computers are the stuff of science fiction - in last summer's blockbuster movie Transformers, the bad guys use quantum computing to break into the U.S. Army's secure files in just 10 seconds flat.   view more (2008-04-09)

FSU researchers' material may lead to advances in quantum computing
Scientists at Florida State University's National High Magnetic Field Laboratory and the university's Department of Chemistry and Biochemistry have introduced a new material that could be to computers of the future what silicon is to the computers of today.   view more (2007-10-09)

True randomness upon request
The number of applications requiring random numbers increases continuously. They are used for example in cryptographic applications to guarantee the secrecy of electronic communications, in scientific calculations or in chance games and lotteries. In spite of this, their generation remains a... view more (2004-03-17)

The knee op that helps free the knees up
Most people over the age of 30 have some sort of problem with their knees making walking, running or playing sport uncomfortable, and thousands of people each year have surgery to remove damaged cartilage from within their knees.   view more (2000-01-20)

In tiny supercooled clouds, physicists exchange light and matter
Physicists have for the first time stopped and extinguished a light pulse in one part of space and then revived it in a completely separate location.   view more (2007-02-08)

Quantum Systems Could Flout Physics Law
Scientists in the Weizmann Institute's Faculty of Chemistry, together with colleagues in Germany, have made a startling prediction: Simply 'taking the temperature' of certain quantum systems at frequent intervals might cause them to disobey a hard and fast rule of thermodynamics.   view more (2008-06-03)

'Smart' nanoprobes light up disease
Researchers from Rice University's Center for Biological and Environmental Nanotechnology (CBEN) have developed a "smart" beacon hundreds of times smaller than a human cell that is programmed to light up only when activated by specific proteases.   view more (2005-08-02)

Physics World Digest: October 2002 edition
Let the quantum games begin Imagine Captain Picard and Q from Star Trek playing a "coin-flipping" game on the bridge of the Starship Enterprise. But rather than playing with an ordinary coin, which can only be either heads or tails, they are using a "quantum coin" that can be both heads and tails... view more (2002-10-01)

The Light Is Fighting Cancer
The light helps physicians of the Gertsen Moscow Scientific Research Oncological Institute to fight cancer. The division headed by Professor Sokolov closely collaborates with the department of optical spectroscopy, Prokhorov Institute of General Physics, Russian Academy of Sciences, headed by... view more (2003-06-27)

Quantum Evolution - The New Science of Life
A clue to understanding life is the realisation that its dynamics are different than those that rule the non-living. For inanimate objects, the dynamics we see are the product of the disordered motion of billions of particles; they are a kind of average dynamics. At the macroscopic level we see... view more (2000-01-31)

Magnetic transistor could 'dial in' quantum effects
A team of theoretical and experimental physicists from Rice University is preparing a unique probe in hopes of "dialing in" elusive quantum states called "quantum criticalities."   view more (2005-12-13)

New paper offers insights into 'blinking' phenomena
A new paper by a team of researchers led by University of Notre Dame physicist Bolizsár Jankó provides an overview of research into one of the few remaining unsolved problems of quantum mechanics.   view more (2008-07-02)

Quantum Effects Make the Difference
The atomic constituents of matter are never still, even at absolute zero (-273.15 degrees Celsius). This consequence of quantum mechanics can result in continuous transition between different material states. Physicists at the Max Planck Institute for Chemical Physics of Solids have studied this... view more (2007-03-05)

Blue laser - the alpha and the omega
The future of DVD is blue. New, low-cost optical laser technology generates short-wavelength beams. At the other end of the beam are detector heads that will soon contain arrays of up to 25 sensors. Two Fraunhofer Institutes are taking the lead at both ends of the spectrum. Man's appetite seems to... view more (2004-05-14)
