One-fifth of global electricity consumption is based on lighting; efficient and stable white-light emission with single materials is ideal for applications. Photon emission that covers the entire visible spectrum is, however, ...
One of the key requirements of future optical communications technologies is a nanoscale light source capable of emitting ultrafast light pulses. In a new study, researchers have shown that graphene may be an ideal candidate ...
Researchers have developed a method for achieving an order-of-magnitude enhancement of the light emission from a class of two-dimensional (2D) materials called transition metal dichalcogenides (TMDs). The large light enhancement ...
(PhysOrg.com) -- At very cold temperatures, in the absence of light, a photomultiplier will spontaneously emit single electrons. The phenomenon, which is called "cryogenic electron emission," was first observed nearly 50 ...
(PhysOrg.com) -- While information technology is generally thought to require electrons or photons for transmitting information, scientists have recently demonstrated a third method of transmission: chemical reactions. Based ...
The science fiction author Arthur C. Clarke selected his own seven wonders of the world in a BBC television series in 1997. The only astronomical object he included was SS 433. It had attracted attention already in the late ...
