A quasiparticle called the exciton is responsible for the transfer of energy within devices, such as solar cells, LEDs, and semiconductor circuits, and has been understood for decades, but exciton movement within materials has never been directly observed.>
A small icy object within the rings of Saturn may be a new moon, according to interpretation of images taken with Cassini's narrow angle camera on April 15, 2013 which show disturbances at the very edge of Saturn's A ring -- the outermost of the planet's large, bright rings. One of these disturbances is an arc about>
On the scale of earth-friendly materials, most people don't think of polyester but scientists are figuring out how to extract a natural, waterproof, antibacterial version of it from...cork.Writing in Biomacromolecules, Cristina Silva Pereira and colleagues explain that polyesters are ubiquitous in modern life>
AC, DC: What's The Difference ?The difference between alternating current (AC) and direct current (DC) is readily explained, yet most widely published "explanations" seem to muddle the facts and cause confusion.  I hope that this short article may help to clarify matters a little.A Little EtymologyOriginally>
This idea dates back to the Russians in the 1970s. The surface of Venus is far too hot, and the atmosphere too dense, for Earth life. However, our air is a lifting gas on Venus with about half the lifting power of helium on Eath. A habitat filled with normal air will float high in the dense Venus atmosphere, The atmospheric>
An array of tiny, metallic, U-shaped structures deposited onto a dielectric material creates a new artificial surface that can bend and focus electromagnetic waves the same way an antenna does.>
