Better Light Emitting Diodes and Solar Cells
March 25, 2010 | 4 Comments
Researchers Cun-Zheng Ning and Alian Pan at Arizona State University are developing nanowires could lead to better light-emitting diodes (LEDs) that could replace less energy-efficient incandescent light bulbs and more efficient photovoltaic cells for generating energy from sunlight. The research effort is to improve quaternary alloy semiconductor nanowire materials. Quaternary alloys are made of semiconductors [...]

A Totally Organic Light to Paste on the Wall
February 11, 2010 | 1 Comment
Swedish and American researchers have succeeded in producing a new type of lighting component that’s inexpensive to produce and can be fully recycled. Using the new super material graphene, the invention as an example could pave the way for glowing wallpaper made entirely of plastic. The emerging field of “organic” or “plastic” electronics has already [...]

A Great New Light Bulb
September 21, 2009 | 2 Comments
Vu1 Corporation announced last week that their new technology for a light bulb is going into production. It’s a very interesting take on an old technology. Energy efficient like the compact florescent and pleasing to the eye like an incandescent, the new bulb has a good future. Vu1’s introduction is for their Electron Stimulated Luminescence [...]

A Much Better Light Bulb
June 5, 2009 | 5 Comments
Optics researchers at the University of Rochester led by Chunlei Guo can turn regular incandescent light bulbs into power-sippers. This news after the Congress outlaws incandescent bulbs some years out. Nothing is so dubious as mandating markets and closing off innovation and creativity. But the rest of the world can rejoice, they can see better [...]
