Nanotech Jump For Solar Cells
2012-06-22 05:18:43

Solar power cells are limited by the wavelengths of light they can absorb from the sun. Ideally a solar cell would absorb every wavelength, but to date the goal has not been reached. Silicon, today's photovoltaic industry standard, is limited in the wavelength range it can 'see' and absorb. A possible solution has been found in indium gallium nitride. Using this material, scientists can tune the material's response so it collects solar energy from a variety of wavelengths. The more...

Nano Art: Reloaded - Where Art And Science Collide
2012-04-03 04:38:20

Lee Rannals for RedOrbit.com [ Watch the Video ] Nanotechnology is a science that is being used by most of the Western culture on a daily basis, but the majority of people using do not even know it. People are unaware of the science that goes into making a device like a touchscreen smartphone that fits into a pocket, but Sameer Walavalkar is looking to change that. Nano Art: Reloaded is a project Walavalkar has created to combine both science and art, to bring nanoscale artwork to...

Berkeley Lab Researchers Resolve Controversy Over Gallium Manganese Arsenide that Could Boost Spintronic Performance A long-standing controversy regarding the semiconductor gallium manganese arsenide, one of the most promising materials for spintronic technology, looks to have been resolved. Researchers with the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab)in collaboration with scientist from University of Notre Dame have determined the origin of the...

Risks related to the critical nature of arsenic – used to make high-speed computer chips that contain gallium arsenide – outstrip those of other substances in a group of critical materials needed to sustain modern technology, a new study has found. Scientists evaluated the relative criticality of arsenic and five related metals in a report in the ACS' journal Environmental Science & Technology. T. E. Graedel, E. M. Harper, N. Nassar and colleagues explain that five metals...

Scientists Create Self-Healing Electronic Chips
2011-12-22 13:35:25

Researchers at the University of Illinois at Urbana-Champaign say they are a step closer to developing electronic chips that heal themselves. The scientists created a circuit that heals itself when cracked by using a liquid metal that restored conductivity. They said their work could eventually lead to longer-lasting gadgets, as well as helping out in spacecrafts “Rather than having to build in redundancies or to build in a sensory diagnostics system, this material is designed...

Image 1 - Zinc Oxide Microwires Improve Performance Of Light-emitting Diodes
2011-11-01 03:46:47

Piezo-phototronic effect Researchers have used zinc oxide microwires to significantly improve the efficiency at which gallium nitride light-emitting diodes (LED) convert electricity to ultraviolet light. The devices are believed to be the first LEDs whose performance has been enhanced by the creation of an electrical charge in a piezoelectric material using the piezo-phototronic effect. By applying mechanical strain to the microwires, researchers at the Georgia Institute of Technology...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
