Engineers Create Roll Up Conductors To Save Chip Space
2012-12-14 13:34:45

University of Illinois On the road to smaller, high-performance electronics, University of Illinois researchers have smoothed one speed bump by shrinking a key, yet notoriously large element of integrated circuits. Three-dimensional rolled-up inductors have a footprint more than 100 times smaller without sacrificing performance. The researchers published their new design paradigm in the journal Nano Letters. “It´s a new concept for old technology,” said team leader...

Boosting Heat Transfer With Nanoglue

Rensselaer Polytechnic Institute A team of interdisciplinary researchers at Rensselaer Polytechnic Institute has developed a new method for significantly increasing the heat transfer rate across two different materials. Results of the team´s study, published in the journal Nature Materials, could enable new advances in cooling computer chips and lighting-emitting diode (LED) devices, collecting solar power, harvesting waste heat, and other applications. By sandwiching a layer of...

Northwestern University scientists have developed a thermoelectric material that is the best in the world at converting waste heat to electricity. This is very good news once you realize nearly two-thirds of energy input is lost as waste heat. The material could signify a paradigm shift. The inefficiency of current thermoelectric materials has limited their commercial use. Now, with a very environmentally stable material that is expected to convert 15 to 20 percent of waste heat to useful...

Death Valley Still The Hottest Spot On Earth
2012-09-13 13:39:03

Lee Rannals for redOrbit.com - Your Universe Online Meteorologists have ended an 80-year debate over where and what the hottest temperature ever recorded on Earth was. Back in the summer of 1913, temperatures soared to a scorching 134 degrees Fahrenheit in Death Valley, California, setting a record as the world's hottest temperature. However, less than 10 years later, on September 13, 1922, reports came in of a 136.6 degree Fahrenheit temperature being recorded in El Azizia, Libya....

Steve K´s vaping world releases a new review of Innokin iTaste VV e cigarette performance. (PRWEB) June 22, 2012 The Innokin iTaste VV (version 2) tries to turn what Vapers knows about e cigarettes on their ears. The device features a unique square design, variable voltage and an innovative magnetic connector. It works best in its original, proprietary configuration, but the addition of adapters means it will work with most standard cartomizers. From those who haven´t made the...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
