Newly Developed Light Sensor Could Improve Solar Cells and Cameras
Scientists at the University of Toronto have created a new type of light sensor that acts like a pixel in a digital camera. Researchers believe the sensor, which takes advantage of a phenomenon called multi-exciton generation (MEG), could lead to substantial advancements in the performance of a variety of electronic devices including digital cameras.
Carbonized Chicken Feathers Better Than Carbon Nanotubes at Storing Hydrogen
Delaware University scientists have found that not only the latest hi-tech nanotubes or metal composites can store hydrogen effectively, but also a substance that's been around for millions of years, naturally: carbonized keratin.
Italian Researchers Inventing New Type of Solar Concentrator
Roberto de Luca and Aniello Fedullo from the University Salerno of Italy invented a new solar concentrating device they say is inspired by the Ear of Dionysus. According to the legends, Doinysus's ear had an elliptical cave so he could hear even the weakest whispers of a prisoner in one of the cave's foci.
Sony Ericsson Says Solar Powered Cell Phones Not So Green
Not long ago, I presented some cell phones that, among their many functions, also incorporated a small solar panel, for flexible charging and green purposes. Well, those green purposes prove themselves being not so green, if we take into account recent studies.
Tiny Biological Fuel Cells Could Power Future Implants
Scientists at the University of Georgia have discovered a new way to grow molecular wire brushes that conduct electrical charges. According to the researchers, this discovery is the first step in developing fuel cells for devices such as cochlear implants, prosthetic limbs and pacemakers.
World's Thinnest Superconductor Ever Created
Dr. Ken Shih and some of his physicist colleagues, have reported the development of the thinnest superconducting metal layer ever created, a superconducting sheet of lead only two atoms thick.
SkySail Offers Big Boats Up to 30% Reduction in Fuel Consumption
Cargo boats are among the most polluting things on Earth after cars. Most of them have no emission control and do not obey regulations put in place only a few years ago. Because their value is huge and their profits are enormous, only unobtrusive green thinking can change the way they travel and pollute the air.
Solar-Powered System Extracts Potable Water from Air
For many people from urban areas the access to potable water is very low. To combat the water crisis, scientists had to design systems that can help provide clean drinking water from something that is omnipresent.
Researchers to Develop Nanomotors Powered by Light
In short time, researchers at the University of Florida will develop nano-robots that can do everything from surgery to cleaning up toxic waste.
Chunlei Guo's Metal Pushing Water Uphill Without Extra Energy
Chunlei Guo, a researcher from the University of Rochester, along with a team of scientists, have created a slab of metal that can push water uphill, defying gravity, by using the capillary effect. It's the same effect that happens when you put a piece of fabric in a wine glass, for example, and hold it with your hand.
