POPSLED Light Bulbs That Last 60 Years to Get Cheaper LEDs are small and don't give off much light, but they last for literally decades (like, 60 years) and give off virtually no heat, making them three times more efficient than the twisty CFL bulbs. Professor Colin Humphreys at Cambridge University has come up with a way to make them far cheaper than normal, creating a more efficient way to produce gallium nitride, a material required for the production of LEDs. His discovery could pave the way to LED bulbs that cost less than $5 a pop. However, we're still at least a few years away before these could go into mass production, meaning you're going to have to keep hitting the Asprin or guiltily using your old incandescent bulbs.

POPS"Innerspace" the artistic landscapes of nano-scale worlds Most artists use a paintbrush or a camera, but Michael Oliveri sometimes prefers a scanning electron microscope. The University of Georgia digital media professor finds inspiration in science, from organic chemistry to space exploration. In his recent project "Innerspace," he explores the landscapes of nano-scale worlds where objects are up to 1,000 times smaller than the width of a human hair. beautiful. The samples Oliveri captures come from University of Georgia materials scientist Zhengwei Pan, who creates nanowires and other puny structures that may one day lead to miniscule electronics. Pan heats metals up to temps so hellish that they turn into vapor. Then the metals settle down to form rods, spheres and other shapes. Oliveri combines up to 40 smaller images to create his panoramas, which resemble familiar cornfields and underwater vistas.

POPSElemental extinction? With Intel churning out a billion transistors on a chip, it's no wonder that hafnium is becoming more scarce. Fascinating idea. Wonder if it will incite a lobbying effort? thx to Tim O'Reilly for original pointer.

POPSFirst Nano-Bible Created The nano-Bible will be photographed and expanded 10,000 times, and still be able to fit into a seven-by-seven-meter frame, to be hung in the Technion's physics faculty. The photograph will make it possible to read the entire Bible with the naked eye, and the height of each letter will be three millimeters. Zohar said the original nano-Bible, the size of a crystal of sugar, would be displayed next to the photograph.

POPSA nanotech Bible " A nanometer is equal to one billionth of meter or one millionth of a millimeter. The resulting letters can be observed only with a scanning electron microscope. " the original nano-Bible ia the size of a crystal of sugar. It will be displayed near a 7 by 7 meter photo (10,000 times expanded) hung in the Technion physics faculty. make the 10 mullion bits text possible 2b read with a naked eye.

POPSMaintaining Moore's Law without Silicon As the device shrinks, the performance loss of transistors made of compound semiconductors is less severe than those of silicon because there was so much more performance to begin with. The new transistors can carry 2.5 times more electrical current than the comparable silicon transistors, translating into faster operation.

POPSMaking Gasoline from Carbon Dioxide Researchers at the University of California, San Diego (UCSD), recently demonstrated that light absorbed and converted into electricity by a silicon electrode can help drive a reaction that converts carbon dioxide into carbon monoxide and oxygen. For solar panels to be useful when the sun isn't shining, the electricity they produce has to be stored. A potentially practical way of doing that is by converting the electrical energy into chemical energy. One popular approach is to use solar cells to produce hydrogen, which could then be used in fuel cells.

POPSNew Technology For Manufacturing Flexible Solar Cells It also provides for lightweight and flexible solar cell panels that could find interest in the space, military and recreational markets. For standard applications, the solar cells can also be encapsulated into a more traditional rigid structure. By being flexible, the solar cells can conform to different surfaces, Eser said, adding this is “particularly important for roofing applications for building integration, and for airships and balloons.” The solar cell sheets are created by depositing copper-indium-gallium-diselinide, which the IEC scientists call CIGS, on a 10-inch wide polymer web, which is then processed into the flexible solar cells. CIGS solar cells are currently the only thin-film technology that has achieved efficiencies comparable to silicon solar cells, presently the standard of the industry.
