NSBP member, Nadya Mason, leads group to isolate bound states in graphene-superconductor junctions
PhysOrg.com    Share   Share on FacebookTwitterShare on LinkedinE-mail article
Professor Nadya Mason's group at the University of Illinois-Urbana Champaign has documented the first observations of some unusual physics when two prominent electric materials are connected: superconductors and graphene. Electrons in superconductors are conducted in electron-electron pairs. In normal conducting materials electrons are conducted as a stream of single electrons. But when a normal conducting material is sandwiched between two layers of a superconducting material, the electrons are conducted in via Andreev bound states (ABS), special electron-hole pairs. Mason's group was able to directly observe ABS by using graphene quantum dots as the normal conducting material, which confines the ABS energies to discrete levels. More

Physicists solve puzzle of 'ionization surprise'
ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Over 30 years of experiments and computations physicists had thought they completely understood the ionization of atoms and molecules in strong laser fields. But in 2009 there were two reports of seeming anomalous "spikes" in the photoelectron spectra when using a low energy laser. The feature was most prominent when using midinfrared laser wavelengths and was dubbed the ionization surprise. These spectra defied description using the workhorse theoretical construction of photoionization under these conditions, the so-called strong-field approximation. But a more complete description, reported in Physical Review Letters, that explicitly takes into account the Coloumb interaction between the departing electron and the resulting ion reproduces the spectra convincingly.

Molybdenite transistors may rival graphene-based devices
PhysicsWorld    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers in Switzerland have made the first working transistors made from flakes of molybdenite just one molecule thick. A mixture of molybdenum and sulphur, the material is a semiconductor with direct bandgap, which means that could be better than silicon for making certain photonic devices. Indeed, the scientists believe molybdenite could even rival "wonder material" graphene in its potential for use in future electronic circuits. More

Video: Hakeem Oluseyi, The Big Bang: How do we know?

Scientists pleased with President Obama's 2012 budget proposal
LiveScience    Share    Share on FacebookTwitterShare on LinkedinE-mail
article
For the most part, federal investment in science fared well in the administration's 2012 budget proposal. In the science realm, there were more winners than losers in the comprehensive government spending proposal. National Science Foundation funding went up by 13 percent, while the Centers for Disease Control and Prevention lost 9 percent. Considering soaring federal deficits and calls for fiscal austerity, advocates for science were generally pleased. More

But the increases are articulated over fiscal year-2010 levels. The current year's budget, fiscal year-2011, is still not resolved, and the GOP is calling for deep cuts in current year appropriations, including a 14 percent cut of the Department of Energy Office of Science. More


What does the political upheaval in Egypt mean for science?
SciDev.net    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers are reported to have been prominent among the protesters. Frustrations among scientists in Egypt have been bubbling below the surface for many years. Some have focused on the lack of adequate support for high-class research in the country, where low academic salaries have forced many scientists to either dilute their energies by taking second jobs, or to join the brain drain. U.S.-based, but Egyptian-born chemistry Nobel Laureate, Ahmed Zewail, recently returned to his home country to join a group of prominent Egyptian intellectuals who are drawing up plans, including constitutional reforms, to try to engineer a peaceful transition to democracy. Hopes are that proper reforms will spread beyond Egypt and into other Mideast and African nations. More

How Morocco faces the challenge of science literacy
SciDev.net    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Moroccans are receptive to science, but the country needs a much stronger communication and scientific literacy effort. But engaging the public with science probably means something different in Morocco than it does in more developed countries. More

Educational astronomy project awarded grant of $2.6 million
International Astronomical Union    Share    Share on FacebookTwitterShare on LinkedinE-mail
article
The European Union has granted $2.6 million to support the six-country educational program EUNAWE, based on Universe Awareness (UNAWE). UNAWE is, an International Astronomical Union (IAU)-endorsed program that uses the beauty and grandeur of the universe to encourage young children, particularly those from an underprivileged background, to have an interest in science and technology and foster their sense of global citizenship from the earliest age. UNAWE is also an integral part of the IAU Strategic Plan 2010–2020, which is called Astronomy for the Developing World. More

Study of volcanoes in the outer solar system produces unexpected bonus for nanotechnology
ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Mysterious expanding ice crystals in the moons of Saturn and Neptune may be of interest to future developers of microelectronics. Neutron scattering has discovered that methanol crystals that may be found in outer solar system 'ice lavas' have unusual expansion properties. The unexpected finding by a British planetary geologist using neutrons at the Institut Laue-Langevin and the ISIS neutron source will interest developers of 'nano-switches' — single atom thick valves used in 'micro-electronics' at the nano scale.

'Let the sun shine': The future's bright with the African network for solar energy
Institute of Nanotechnology    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The newly created 'African Network for Solar Energy' (ANSOLE)recently met in Austria in a dynamic and fruitful second symposium that saw it make great strides in planning the next phase of its development. The network aims to foster research activities in the field of solar energy among African scientists working within Africa and those in the diaspora. In the first instance, it will connect and skill up young Africans in the solar energy field with an overarching objective of developing solar energy research capacity. The next ANSOLE meeting will take place during the 6th Africa Materials Research Society (Africa-MRS) Conference: Dec. 11-16, Victoria Falls, Zimbabwe, which will host a large gathering of high profile scientists and researchers.

Physics for financial markets
Science Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
As a result of the financial crisis, many countries are trying to regulate their financial markets. The use of two fundamental mechanisms from physics, friction and noise, could provide a solution. These mechanisms can be viewed as setting boundaries to the system's self-organization, rather than impeding it. More

Turning air into a laser
Optics and Photonics News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
By pumping a small cylindrical volume of air with ultraviolet laser light, researchers created an oxygen laser emitting in the near-infrared with directional emission along the cylindrical axis. With further development, the system could be used for remote detection of hazardous gasses and vapor indicators of explosives. More
