Surprising graphene: Honing in on graphene electronics with infrared synchrotron radiation

June 08, 2008 | User rating: 4.6 / 5 after 18 vote(s) | User comments: 4

Graphene is the two-dimensional crystalline form of carbon: a single layer of carbon atoms arranged in hexagons, like a sheet of chicken wire with an atom at each nexus. As free-standing objects, such two-dimensional ...


A 'supra' new kind of froth

June 05, 2008 | User rating: 4.1 / 5 after 15 vote(s) | User comments: 6

To see the latest science of type-I superconductors, look no further than the froth on a morning cup of cappuccino. A team of U.S. Department of Energy's Ames Laboratory physicists and collaborating students ...


A glass apart

June 05, 2008 | User rating: 4.5 / 5 after 24 vote(s) | No comments yet

British scientists are developing a new type of glass that can dissolve and release calcium into the body. This will enable patients to regrow bones and could signal a move away from bone transplants.

The long cherished goal of applying the strange properties of quantum mechanics to the macroscopic world we inhabit has been brought closer by a series of recent developments. The exciting progress was made in the important ...


'Squeezed' Light May Improve Gravitational Wave Detectors

June 05, 2008 | User rating: 4.6 / 5 after 54 vote(s) | User comments: 20

A research collaboration has taken steps toward improving the sensitivity of gravitational wave detectors, devices designed to measure distance changes as minute as one-thousandth the diameter of a proton. ...


New superconductors present new mysteries, possibilities

June 04, 2008 | User rating: 4.2 / 5 after 40 vote(s) | User comments: 9

Johns Hopkins University researchers and colleagues in China have unlocked some of the secrets of newly discovered iron-based high-temperature superconductors, research that could result in the design of better superconductors ...


New Metamaterial a 'Perfect' Absorber of Light

June 03, 2008 | User rating: 4.4 / 5 after 68 vote(s) | User comments: 15

A team of scientists from Boston College and Duke University has developed a highly-engineered metamaterial capable of absorbing all of the light that strikes it – to a scientific standard of perfection – ...


Novel 'noise thermometry' may help redefine international unit of temperature

June 03, 2008 | User rating: 4.5 / 5 after 13 vote(s) | No comments yet

After seven years of work, researchers at the National Institute of Standards and Technology have built a system that relies on the "noise" of jiggling electrons as a basis for measuring temperatures with ...


Terahertz laser source at room temperature

June 03, 2008 | User rating: 4.6 / 5 after 41 vote(s) | User comments: 1

“There is a growing interest in utilizing terahertz radiation, or T-rays, for a variety of applications,” Mikhail Belkin, a scientist at Harvard University, tells PhysOrg.com. “The terahertz region is a part of the ...


Finding out what the Big Bang and ink jets have in common

June 03, 2008 | User rating: 4.2 / 5 after 17 vote(s) | No comments yet

It often turns out there is more to commonplace everyday events than meets the eye. The folding of paper, or fall of water droplets from a tap, are two such events, both of which involve the creation of singularities requiring ...


Scientists find new 'quasiparticles'

June 02, 2008 | User rating: 4.4 / 5 after 50 vote(s) | User comments: 2

Weizmann Institute physicists have demonstrated, for the first time, the existence of 'quasiparticles' with one quarter the charge of an electron. This finding could be a first step toward creating exotic types of quantum ...


Physicists determine density limit for randomly packed spherical materials

June 02, 2008 | User rating: 3.5 / 5 after 21 vote(s) | User comments: 2

The problem of how many identical-sized spheres can be randomly packed into a container has challenged mathematicians for centuries. A team of physicists at The City College of New York (CCNY) has come up with a solution ...


Scientists show quantum systems could flout physics law

June 02, 2008 | User rating: 4.3 / 5 after 55 vote(s) | User comments: 11

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 ...


Synergy between biology and physics drives cell-imaging technology

June 02, 2008 | User rating: 4.3 / 5 after 6 vote(s) | User comments: 1

Developing techniques to image the complex biological systems found at the sub-cellular level has traditionally been hampered by divisions between the academic fields of biology and physics. However, a new interdisciplinary ...


Evidence of a Bose glass state?

May 30, 2008 | User rating: 4.5 / 5 after 51 vote(s) | User comments: 1

"In nano-sized systems many physical properties are greatly altered from those of macroscopic-sized systems. Therefore, study of nano-sized systems, in general, is very important in developing fundamental physics," Keiya ...
