Improved Spin Transistor from Oxford University
Researchers at Oxford University’s Physics Department have developed an improved version of the “spin transistor,” a device which has the principle operating characteristics of a conventional transistor but with the added benefit of a current output dependent on the strength of... view more (2002-08-15)

Wired DNA
The hereditary DNA molecule was developed by nature to store the genetic information of its creatures. However in recent years it has been shown that this giant molecule could also have other qualities - it may also conduct electrical current. Three research groups that are looking into this... view more (1999-03-23)

Making waves in cancer detection
We`re all familiar with X-rays being used to look inside our bodies. But according to physicists, medical imaging in the future is likely to be based on an as yet unused type of radiation known as terahertz radiation.   view more (2002-07-23)

Microbial Fuel Cells: Optimization Of The Anode Compartment For Improved Electron Transfer
A microbial fuel cell mimics a biological system, in which bacteria do not directly transfer the energy-rich electrons gained out of the feeding to their characteristic electron acceptor. Instead, the electrons are diverted towards an electrode (anode) and subsequently conducted over a resistance... view more (2003-11-14)

Physicists describe a new mechanism for metallic magnetism
Predicting the magnetic behavior of metallic compounds is a surprisingly difficult problem for theoretical physicists.   view more (2005-08-26)

Protons pair up with neutrons
Research performed at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has found that protons are about 20 times more likely to pair up with neutrons than with other protons in the nucleus.   view more (2008-05-30)

Biofuel cells without the bio cells
Proteins keep cells humming. Some are enzymes that taxi electrons to chemicals outside the cell, to discharge excess energy generated during metabolism. This maintains energy flow in the cell and, in turn, keeps the cell alive.   view more (2006-10-18)

Researchers at University of Pennsylvania develop method for mass production of nanogap electrodes
Researchers at the University of Pennsylvania have developed a reliable, reproducible method for parallel fabrication of multiple nanogap electrodes, a development crucial to the creation of mass-produced nanoscale electronics.   view more (2007-08-17)

Oregon physicists don't flip spin but find possible electron switch
University of Oregon researchers trying to flip the spin of electrons with laser bursts lasting picoseconds (a trillionth of a second) instead found a way to manipulate and control the spin -- knowledge that may prove useful in a variety of new materials and technologies.   view more (2008-05-28)

Northeastern U researchers answer longstanding question in the field of condensed matter physics
ortheastern University Physics professor Sergey V. Kravchenko along with colleagues Svetlana Anissimova (Northeastern University), A Punnoose (City College if the City University of New York), AM Finkelstein (Weizmann Institute of Science, Israel) and TM Klapwijk (Delft University of Technology,... view more (2007-08-07)

NRL scientists demonstrate efficient electrical spin injection into silicon
Scientists at the Naval Research Laboratory (NRL) have efficiently injected a current of spin-polarized electrons from a ferromagnetic metal contact into silicon, producing a large electron spin polarization in the silicon.   view more (2007-07-17)

Electron pairs precede high-temperature superconductivity
Like astronomers tweaking images to gain a more detailed glimpse of distant stars, physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have found ways to sharpen images of the energy spectra in high-temperature superconductors - materials that carry electrical current... view more (2008-11-06)

'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)

High Power Laser for Ultraviolet Light
An international team of scientists at the research center DESY recently succeeded in obtaining the maximum light amplification from a "free electron laser" (FEL) for ultraviolet radiation. The electron laser produced an amplification of 10 million - this corresponds to the theoretically expected... view more (2001-09-19)

Physicists offer new approach to studying antimatter
What happens when two atoms, each made up of an electron and its antimatter counterpart, called the positron, collide with each other?   view more (2005-11-01)
