Researchers from the University of Toronto (U of T), the King Abdullah University of Science & Technology (KAUST) and Pennsylvania State University (Penn State) have created the most efficient solar cell ever made based on collodial-quatum-dots (CQD). The discovery is reported in the latest issue of Nature Materials. Quantum dots are nanoscale semiconductors that capture light and convert it into an energy source. Because of their small scale, the dots can be sprayed on to flexible...

In the quest to exploit unique properties at the nanoscale, scientists at Stevens Institute of Technology have developed a novel technique for creating uniform arrays of metallic nanostructures. A team of faculty and students in the Department of Physics and Engineering Physics, led by Dr. Stefan Strauf, appropriated methods from holographic lithography to demonstrate a new approach for scaling up the fabrication of plasmonic nanogap arrays while simultaneously reducing costs and...

  Berkeley Lab researchers develop inexpensive technique for making high quality nanowire solar cells Solar or photovoltaic cells represent one of the best possible technologies for providing an absolutely clean and virtually inexhaustible source of energy to power our civilization. However, for this dream to be realized, solar cells need to be made from inexpensive elements using low-cost, less energy-intensive processing chemistry, and they need to efficiently and...

University of Florida researchers may help resolve the public debate over America's future light source of choice: Edison's incandescent bulb or the more energy efficient compact fluorescent lamp. It could be neither. Instead, America's future lighting needs may be supplied by a new breed of light emitting diode, or LED, that conjures light from the invisible world of quantum dots. According to an article in the current online issue of the journal Nature Photonics, moving a QD LED from...

Using a modern version of open-wide-and-keep-this-under-your-tongue, scientists today reported taking the temperature of individual cells in the human body, and finding for the first time that temperatures inside do not adhere to the familiar 98.6 degree Fahrenheit norm. They presented the research at the 242nd National Meeting & Exposition of the American Chemical Society (ACS), being held here this week. Haw Yang and Liwei Lin, who collaborated on the research, did not use a familiar...

Kiel researchers discover novel state of crystal matter Nature knows two opposite types of solids: one that emerges upon compression from a liquid and a second that appears if the pressure on a liquid is reduced. While the former is typical for substances in our everyday life the latter occurs for example in a dense quantum liquid of electrons (such as in metals) or ions (in exotic white dwarf or neutron stars). Now it has been shown that there exists yet a third form of matter that inherits...


Word of the Day
ween
  • To think; to imagine; to fancy.
  • To be of opinion; have the notion; think; imagine; suppose.
The word 'ween' comes from Middle English wene, from Old English wēn, wēna ("hope, weening, expectation"), from Proto-Germanic *wēniz, *wēnōn (“hope, expectation”), from Proto-Indo-European *wen- (“to strive, love, want, reach, win”).
