An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester.
At "Laser 2009" in Munich, June 15 to 18, Fraunhofer researchers will be demonstrating how laser technology can contribute to optimizing the manufacturing costs and efficiency of solar cells.
BERKELEY, CA ? Multiferroics are materials in which unique combinations of electric and magnetic properties can simultaneously coexist. They are potential cornerstones in future magnetic data storage and spintronic devices provided a simple and fast way can be found to turn their electric and magnetic properties on and off. In a promising new development, researchers with the U.S.
Ultrafast laser research at Kansas State University has allowed physicists to build on Nobel Prize-winning work in photo-electronics by none other than Albert Einstein.
Einstein received the Nobel Prize in 1921 for his theoretical explanation in 1905 of the so-called photo-effect -- that is, the emission of electrons from a metal surface by incident light.
Chip manufacturers beware: There's a newfound flaw in our understanding of transistor noise, a phenomenon affecting the electronic on-off switch that makes computer circuits possible.
Of the 92 naturally occurring elements, add another to the list of those that are superconductors.
Researchers at UCLA have developed a new method for producing a hybrid graphene-carbon nanotube, or G-CNT, for potential use as a transparent conductor in solar cells and consumer electronic devices. These G-CNTs could provide a cheaper and much more flexible alternative to materials currently used in these and similar applications.
America's power grid today resembles the country's canal system of the 19th Century. A marvel of engineering for its time, the canal system eventually could not keep pace with the growing demands of transcontinental transportation.
HOUSTON -- (April 29, 2009) -- Spanish and U.S. physicists studying nanoelectronics have found that size really does matter when it comes to predicting the behavior of electrical contacts that are just one atom wide.
Solar energy has the potential to improve the living conditions of poor rural households in India as well as contribute to the country's future energy security, according to Professor Govindasamy Agoramoorthy from Tajen University, who is Tata-Sadguru Visiting Chair, and Dr. Minna Hsu from the National Sun Yat-sen University in Taiwan.
Gas power plants could be cheaply retrofitted to generate hydrogen as well as power, chemists say in a Royal Society of Chemistry journal.
A catalyst would convert methane into hydrogen gas and combustible coke, allowing the power station to produce hydrogen alongside electricity.
In reading the current issue of New Scientist, I found a pointer to a blog entry called "Bug eats electricity, farts biogas."
Needless to say, I had to learn more.
HOUSTON - (April 15, 2009) - Scientists at Rice University have found a simple way to create basic elements for aircraft, flat-screen TVs, electronics and other products that incorporate sheets of tough, electrically conductive material.
And the process begins with a zipper.
CORVALLIS, Ore. - Engineers at Oregon State University have discovered a way to use an ancient life form to create one of the newest technologies for solar energy, in systems that may be surprisingly simple to build compared to existing silicon-based solar cells.
The secret: diatoms.
The prairies offer opportunities for capitalizing on environmentally friendly farming practices and potentially useful agricultural waste to produce jobs, economic growth, commercial opportunities, and renewable energy sources, according to a perspective article published in the current issue of the International Journal of Private Law.
