Warm water vibrates for longer
Dutch researcher Arjan Lock has investigated the behaviour of vibrating water molecules. Using ultra-short laser pulses, he found that hydrogen atoms in water molecules vibrate for longer at higher temperatures. This is abnormal because in the majority of substances a vibration lives shorter at higher temperatures. Lock studied the OH-stretch... view more... (2004-02-05)
Photon-transistors for the supercomputers of the future
Scientist from the Niels Bohr Institute at University of Copenhagen and from Harvard University have worked out a new theory which describe how the necessary transistors for the quantum computers of the future may be created. The research has just been published in the scientific journal Nature Physics. view more (2007-08-27)
A Single-Photon Server with Just One Atom
Every time you switch on a light bulb, 10 to the power of 15 (a million times a billion) visible photons, the elementary particles of light, are illuminating the room in every second. If that is too many for you, light a candle. view more (2007-03-13)
Loose grip
Carbon dioxide (CO2) is contained in the air we exhale, and is also always formed when carbon-containing substances such as oil, gas, wood, and plastics are burned - it is omnipres-ent. Chemists have long been trying to convert this gas to something useful, and Koji Tanaka and coworkers from the Institute for Molecular Science in Myodaiji, Japan,... view more... (1999-01-28)

NIST scientists use electron beam to unravel the secrets of an 'atomic switch'
Scientists at the Commerce Department's National Institute of Standards and Technology (NIST) have used a beam of electrons to move a single atom in a small molecule back and forth between two positions on a crystal surface, a significant step toward learning how to build an "atomic switch" that turns electrical signals on and off in... view more...

University of Oklahoma Researchers Discover Giant Rydberg Atom Molecules
A group of University of Oklahoma researchers led by Dr. James P. Shaffer, Homer L. Dodge Department of Physics and Astronomy, have discovered giant Rydberg molecules with a bond as large as a red blood cell. view more (2009-06-25)
Unlocking the secret of the Kondo Effect
A team of scientists including researchers from the London Centre for Nanotechnology at UCL (University College London) and the IBM Almaden Research Center has forged a breakthrough in understanding an intriguing phenomenon in fundamental physics: the Kondo effect. The findings are reported online today in the scientific journal Nature Physics. view more (2008-09-22)
Beyond the bonds that bind: UCSB researchers discover hydrogen can form multicenter bonds
Researchers at the University of California, Santa Barbara have shown that, under the right circumstances, hydrogen can form multicenter bonds, where one hydrogen atom simultaneously bonds to as many as four or six other atoms. view more (2006-12-04)
Super atoms turn the periodic table upside down
Researchers at Delft University of Technology (TU Delft) in The Netherlands have developed a technique for generating atom clusters made from silver and other metals. Surprisingly enough, these so-called super atoms (clusters of 13 silver atoms, for example) behave in the same way as individual atoms and have opened up a whole new branch of... view more...

New system for detection of single atoms
Scientists have devised a new technique for real-time detection of freely moving individual neutral atoms that is more than 99.7% accurate and sensitive enough to discern the arrival of a single atom in less than one-millionth of a second, about 20 times faster than the best previous methods. view more (2009-05-18)
Scientists Discover Magnetic Superatoms
A team of Virginia Commonwealth University scientists has discovered a 'magnetic superatom' - a stable cluster of atoms that can mimic different elements of the periodic table - that one day may be used to create molecular electronic devices for the next generation of faster computers with larger memory storage. view more (2009-06-16)
Unusual carbohydrate structure in the cell walls of tuberculosis bacteria-a new point of attack for drugs?
Even though we have lost much of our fear of tuberculosis in the industrialized countries, according to the WHO about 2 mio. people worldwide die each year of this infectious disease. Researchers at the University of Leeds have now discovered a carbohydrate with an unusual structure in the cell walls of Mycobacterium tuberculosis, the bacterium... view more... (2004-07-27)
Carbon molecule with a charge could be tomorrow's semiconductor

Classical Physics falls short
With the aid of so-called quantum dots, PhD student Wilfred van der Wiel has gained new insight into quantum-mechanical processes. "This is one of the paths that could lead to smaller, but also fundamentally different electronics, " says Van der Wiel. He will receive his degree on 28 January for his fundamental research. Parts of his... view more... (2002-01-20)
