Combining 6 photons together results in highly robust quantum informationOctober 6th, 2009 WASHINGTON - In a new research, a team of physicists in Sweden and Poland has found that combining 6 photons together can result in highly robust qubits, or quantum information. Exploiting quantum mechanics for transmitting information is a tantalizing possibility because it promises secure, high-speed communications.
Physicists observe magnetism in gas for the first timeOctober 3rd, 2009 TORONTO - An international team of physicists has for the first time observed magnetic behaviour in an atomic gas, addressing a decades-old debate as to whether it is possible for a gas or liquid to become ferromagnetic and exhibit magnetic properties. "Magnets are all around us - holding postcards on the refrigerator, pointing to magnetic north on a compass, and in speakers and headphones - yet some mysteries remain," said Joseph H.
Scientists solve problem of building carbon nanotubes with right structureSeptember 21st, 2009 WASHINGTON - A pair of Case Western Reserve University researchers has come out with a method that solves the problem of building carbon nanotubes with the right structure. The method has been developed by R.
New graphite-based nano-material may herald next generation of electronic devicesSeptember 3rd, 2009 WASHINGTON - An international team of researchers has designed a new graphite-based, magnetic nano-material that acts as a semiconductor and could help material scientists create the next generation of electronic devices like microchips. The nano-material was designed by a team of researchers from Virginia Commonwealth University (VCU); Peking University in Beijing, China; the Chinese Academy of Science in Shanghai, China; and Tohoku University in Sedai, Japan.
Tooth enamel can inspire lighter, stronger aircraftAugust 20th, 2009 WASHINGTON - A study has revealed that the structure of tooth enamel holds promising clues for aerospace engineers as they build planes and space vehicles of the future. Herzl Chai of Tel Aviv University (TAU) School of Mechanical Engineering, who led the study with George Washington University, said: "Teeth are made from an extremely sophisticated composite material which reacts in an extraordinary way under pressure."
The researchers applied varying degrees of mechanical pressure to hundreds of extracted teeth, and studied what occurred on the surface and deep inside them.
Graphane may help make tiny strips of graphene needed for electronic circuitsAugust 1st, 2009 WASHINGTON - In a new research, scientists have explained how their discovery of graphane could make it easier for the production of tiny strips of graphene needed for electronic circuits. Graphane was discovered by Kostya Novoselov - a condensed-matter physicist from the Manchester University group.
New isotope cluster could lead to better understanding of carbon cycleJuly 15th, 2009 WASHINGTON - A team of researchers has discovered an unexpected concentration of a certain isotopic molecule in parts of the stratosphere that could have implications for understanding the carbon cycle and its response to climate change. By analyzing samples of air taken from the stratosphere-the layer of Earth's atmosphere that sits between six and 30 miles above the surface-the team found a much higher concentration of 16O13C18O at high latitudes than expected.
Bilayer graphene to pave way for tunable electronic devicesJune 11th, 2009 LONDON - Researchers at the University of California, Berkeley, have shown that a form of carbon called graphene has an electronic structure that can be controlled by an electrical field, a finding that may pave the way for a host of tunable electronic and photonic devices-such as transistors, LEDs and lasers. Principal author Feng Wang, UC Berkeley assistant professor of physics, claims that this is the first ever demonstration that bilayer graphene exhibits an electric field-induced, broadly tunable bandgap.
Thinnest superconducting metal layer created by physicistsJune 9th, 2009 WASHINGTON - Physicists at the University of Texas at Austin, US, have created a superconducting sheet of lead only two atoms thick, the thinnest superconducting metal layer ever created. Superconductors are unique because they can maintain an electrical current indefinitely with no power source.
US physicists create thinnest superconducting metalJune 8th, 2009 WASHINGTON - A superconducting metal sheet with just two atoms thick has been developed by physicists at the University of Texas in Austin. The university said in a statement Monday that it was the thinnest superconducting metal layer ever created.
Enabling graphene-based technology via chemical functionalizationMay 18th, 2009 WASHINGTON - A team of scientists has identified conditions for enabling graphene-based technology through chemical functionalization. Graphene is an atomically thin sheet of carbon that has attracted significant attention due to its potential use in high-performance electronics, sensors and alternative energy devices such as solar cells.
Inexpensive plastic used in CDs could improve aircraft, computer electronicsMay 16th, 2009 WASHINGTON - An inexpensive plastic used to manufacture CDs and DVDs will one day soon be put to use in improving the integrity of electronics in aircraft, computers and iPhones. Thanks to a pair of grants from the US Air Force, Shay Curran, associate professor of physics at UH, and his research team have demonstrated ultra-high electrical conductive properties in plastics, called polycarbonates, by mixing them with just the right amount and type of carbon nanotubes.
Physicists create world's smallest incandescent lampMay 7th, 2009 WASHINGTON - A team from the UCLA (University of California Los Angeles) Department of Physics and Astronomy has created the world's smallest incandescent lamp. The team that developed the lamp was led by Chris Regan, a member of the California NanoSystems Institute at UCLA, and includes Yuwei Fan, Scott Singer and Ray Bergstrom.
New blockbuster: Watch a carbon atom make a moveApril 1st, 2009 WASHINGTON - Researchers working with the world's most powerful electron microscope have filmed carbon atoms in live motion for the first time, as the atoms repositioned themselves around the edge of a hole punched into a graphene sheet. Viewers of the 'movie' that promises to become a blockbuster - at least over the Internet - observed chemical bonds breaking and forming as the suddenly volatile atoms are driven to find a stable configuration.
Carbon nanotubes may replace metals in electronic applicationsMarch 21st, 2009 WASHINGTON - Scientists at the University at Buffalo Single Walled Carbon Nanotubes (SWCNTs), which are thousands of times stronger than metals, may one day replace metals in millions of electronic applications. Professor Cemal Basaran, the director of the Electronics Packaging Lab in UB's School of Engineering and Applied Sciences, says that the four years of quantum mechanics calculations performed by him and his doctoral student Tarek Ragab have proved that higher current density in carbon nanotubes does not lead to electromigration and thermomigration.
