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 ...

Planetary dashboard shows 'Great Acceleration' in human activity since 1950

January 16, 2015 11:44 am | by EurekAlert! | Comments

Human activity, predominantly the global economic system, is now the prime driver of change in the Earth System (the sum of our planet's interacting physical, chemical, biological and human processes), according to a set of 24 global indicators, or "planetary dashboard" ...

Rice-sized laser bodes well for quantum computing

January 16, 2015 11:38 am | by EurekAlert! | Comments

Princeton University researchers have built a rice grain-sized laser powered by single electrons tunneling through artificial atoms known as quantum dots. The tiny microwave laser, or "maser," is a demonstration of the fundamental interactions between ...

Training the next generation of power engineers

January 16, 2015 11:34 am | by EurekAlert! | Comments

Most people only think about the electricity that powers our homes and gadgets when it isn't there. When the power is humming, we tend to take it for granted. The trouble is, the network that delivers the electricity to keep our lights on, known as the grid ...

Planets outside our solar system more hospitable to life than thought

January 16, 2015 11:29 am | by EurekAlert! | Comments

A study by astrophysicists at the University of Toronto suggests that exoplanets - planets outside our solar system - are more likely to have liquid water and be more habitable than we thought. "Planets with potential oceans could have a climate that is much ...

Improved interface for a quantum Internet

January 16, 2015 9:25 am | by University of Innsbruck | Comments

Quantum computers are no longer just a theoretical concept. In recent years, researchers have assembled and successfully tested the building blocks for a future quantum computer in the laboratory. More than a dozen candidate technologies are currently ...
