How fast do electrons move through single atomic layers?

January 16, 2015 3:59 pm | by EurekAlert! | Comments

The time frames, in which electrons travel within atoms, are unfathomably short. For example, electrons excited by light change their quantum-mechanical location within mere attoseconds - an attosecond corresponds to a billionth of a billionth of ...

Charge ordering in electron-doped copper-oxide crystals

January 16, 2015 3:51 pm | by EurekAlert! | Comments

Researchers have spotted charge ordering - a phenomenon that interferes with superconductivity - in electron-doped copper-oxide crystals for the first time. The discovery is a critical step towards achieving zero electrical resistance at room temperature....

Charge instability detected across all types of copper-based superconductors

January 16, 2015 3:46 pm | by EurekAlert! | Comments

Superconductors made of copper-oxide ceramics called cuprates are capable of conducting electricity without resistance at record-high temperatures--but still only at about one-third of room temperature. They also require cooling with liquid nitrogen, which is not ...

Breakthrough lights up metamaterials

January 16, 2015 1:56 pm | by EurekAlert! | Comments

A City College of New York led-team has successfully demonstrated how to both enhance light emission and capture light from metamaterials embedded with light emitting nanocrystals. The breakthrough, headed by physicist Dr. Vinod Menon, could lead to ...

Software that calculates everyday risks

January 16, 2015 1:41 pm | by EurekAlert! | Comments

Imagine that you could tell your phone that you want to drive from your house in Boston to a hotel in upstate New York, that you want to stop for lunch at an Applebee's at about 12:30, and that you don't want the trip to take more than four hours. Then imagine ...

Solving an organic semiconductor mystery

January 16, 2015 1:34 pm | by EurekAlert! | Comments

Organic semiconductors are prized for light emitting diodes (LEDs), field effect transistors (FETs) and photovoltaic cells. As they can be printed from solution, they provide a highly scalable, cost-effective alternative to silicon-based devices. Uneven performances ...

Carbon nanotube finding could lead to longer-lasting flexible electronics

January 16, 2015 1:27 pm | by EurekAlert! | Comments

University of Wisconsin-Madison materials engineers have made a significant leap toward creating higher-performance electronics with improved battery life -- and the ability to flex and stretch. Led by materials science Associate Professor Michael Arnold ...

Technological replacement for bulk data collection doesn't exist

January 16, 2015 1:24 pm | by EurekAlert! | Comments

No software-based technique can fully replace the bulk collection of signals intelligence, but methods can be developed to more effectively conduct targeted collection and to control the usage of collected data, says a new report from the National Research ...

New material discovery paves way for improved solar panels

January 16, 2015 12:52 pm | by EurekAlert! | Comments

Published today in Nature Communications, University of Melbourne researchers say their discovery of the highly sought-after 'nematic liquid crystals' can now lead to vastly improved organic solar cell performance. Lead author Dr David Jones of the University's ...

Start-up company to commercialise antibody-stabilisation technology

January 16, 2015 12:44 pm | by EurekAlert! | Comments

The Garvan Institute of Medical Research announces the launch of spin-off company Solvanix Pty Ltd, set up to commercialise a novel technology that will improve the stability of therapeutic monoclonal antibodies. Solvanix has secured a $2 million commitment from ...

Inventors choose to reveal their secret sauce before patent approval

January 16, 2015 11:53 am | by EurekAlert! | Comments

Common wisdom and prior economic research suggest that an inventor filing a patent would want to keep the technical know-how secret as long as possible. But a new study of nearly 2 million patents in the United States shows that inventors are not as ...

Physicists detect 'charge instability' across all copper-based superconductors

January 16, 2015 11:50 am | by EurekAlert! | Comments

University of British Columbia physicists have detected 'charge ordering' in electron-doped cuprate superconductors for the first time, according to research published today in Science. Charge ordering is a ripple-like instability at the electron level that ...

MIT team enlarges brain samples, making them easier to image

January 16, 2015 11:46 am | by EurekAlert! | Comments

Beginning with the invention of the first microscope in the late 1500s, scientists have been trying to peer into preserved cells and tissues with ever-greater magnification. The latest generation of so-called "super-resolution" microscopes can see inside cells with resolution ...
