Research findings in solar cells will have an impact on solar panel industry

University of Luxembourg's Laboratory for Photovoltaics has established a method to observe and prevent solar cell degradation before solar cell production is finished, which has implications for the solar cell manufacturing industry since chemical damage to solar cells can occur quickly.

Making crowdsourcing more reliable

Researchers from the University of Southampton are designing incentives for collection and verification of information to make crowdsourcing more reliable.

Crowdsourcing is a process of outsourcing tasks to the public, rather than to employees or contractors. In recent years, crowdsourcing has provided an unprecedented ability to accomplish tasks that require the involvement of a large number of people, often across wide-spread geographies, expertise, or interests.

Palm oil massive source of carbon dioxide

New Haven, Conn. -- Expanding production of palm oil, a common ingredient in processed foods, soaps and personal care products, is driving rainforest destruction and massive carbon dioxide emissions, according to a new study by Yale and Stanford researchers.

The study, published in the journal Nature Climate Change, shows that deforestation for the development of oil palm plantations in Indonesian Borneo is becoming a globally significant source of carbon dioxide emissions.

The graphene-paved roadmap

Writing in Nature, Nobel Prize-winner Professor Kostya Novoselov and an international team of authors has produced a 'Graphene Roadmap' which for the first time sets out what the world's thinnest, strongest and most conductive material can truly achieve.

The paper details how graphene, isolated for the first time at The University of Manchester by Professor Novoselov and colleague Professor Andre Geim in 2004, has the potential to revolutionise diverse applications from smartphones and ultrafast broadband to anticancer drugs and computer chips.

Mine your business: Text mining insights from social media

NEW YORK - October 10, 2012 - Thanks to blogs, online forums, and product review sites, companies and marketers now have access to a seemingly endless array of data on consumers' opinions and experiences. In principle, businesses should be able to use this information to gain a better understanding of the general market and of their own and their competitors' customers.

Light might prompt graphene devices on demand

HOUSTON – (Oct. 10, 2012) – Rice University researchers are doping graphene with light in a way that could lead to the more efficient design and manufacture of electronics, as well as novel security and cryptography devices.

Manufacturers chemically dope silicon to adjust its semiconducting properties. But the breakthrough reported in the American Chemical Society journal ACS Nano details a novel concept: plasmon-induced doping of graphene, the ultrastrong, highly conductive, single-atom-thick form of carbon.

Improving nanometer-scale manufacturing with infrared spectroscopy

One of the key achievements of the nanotechnology era is the development of manufacturing technologies that can fabricate nanostructures formed from multiple materials. Such nanometer-scale integration of composite materials has enabled innovations in electronic devices, solar cells, and medical diagnostics.

Grape consumption associated with healthier dietary patterns

Sacramento, CA (October 9, 2012) – In a new observational study presented today at the Academy of Nutrition and Dietetics Food and Nutrition Conference and Exposition (FNCE) in Philadelphia, PA, researchers looked at the association of grape consumption, in the non-alcoholic forms most commonly consumed – fresh grapes, raisins and 100% grape juice – with the diet quality of a recent, nationally representative sample of U.S. children and adults.

From lectures to explosives detection: Laser pointer identifies dangerous chemicals in real-time

WASHINGTON, Oct. 9, 2012—By using an ordinary green laser pointer, the kind commonly found in offices and college lecture halls, an Israeli research team has developed a new and highly portable Raman spectrometer that can detect extremely minute traces of hazardous chemicals in real time. The new sensor's compact design makes it an excellent candidate for rapid field deployment to disaster zones and areas with security concerns.

Looking out for #1 can make you happy, if you have no choice

We are, at our core, social creatures and we spend considerable time and effort on building and maintaining our relationships with others. As young children, we're taught that "sharing means caring" and, as we mature, we learn to take others' point of view. If we make a decision that favors self-interest, we often feel guilt for prioritizing ourselves over others.

MIT team builds most complex synthetic biology circuit yet

CAMBRIDGE, MA -- Using genes as interchangeable parts, synthetic biologists design cellular circuits that can perform new functions, such as sensing environmental conditions. However, the complexity that can be achieved in such circuits has been limited by a critical bottleneck: the difficulty in assembling genetic components that don't interfere with each other.

App protects Facebook users from hackers

RIVERSIDE, Calif. (www.ucr.edu) — Cyber-crime is expanding to the fertile grounds of social networks and University of California, Riverside engineers are fighting it.

A recent four-month experiment conducted by several UC Riverside engineering professors and graduate students found that the application they created to detect spam and malware posts on Facebook users' walls was highly accurate, fast and efficient.

Solar cells made from black silicon

The Sun blazes down from a deep blue sky – and rooftop solar cells convert this solar energy into electricity. Not all of it, however: Around a quarter of the Sun's spectrum is made up of infrared radiation which cannot be converted by standard solar cells – so this heat radiation is lost. One way to overcome this is to use black silicon, a material that absorbs nearly all of the sunlight that hits it, including infrared radiation, and converts it into electricity. But how is this material produced?

Wireless data at top speed

Whether it's a wedding, birthday party or other celebration, these days the chances are you'll have your camcorder with you to record the great occasion. But we often forget to bring the data cable along with us, so despite promising the hosts to transfer the images to their computer the morning after, we hardly ever do. "No problem," we say, "I'll burn you a CD when I get home." It would be so much easier, though, to transfer the data wirelessly.

An operating system in the cloud

A new-cloud based operating system for all kinds of computer is being developed by researchers in China. Details of the TransOS system are reported in a forthcoming special issue of the International Journal of Cloud Computing.
