Showa Denko K.K. (SDK) has launched its proprietary gallium-nitride-based near ultraviolet and green light-emitting diode (LED) chips for use in general white lighting and backlighting of large LCD screens, respectively....
The researchers measured typical fluctuations in the electron current, which is subject to the frequency of the laser light, and which arose from the chaotic movement of the electrons. The experiment is based on an exper...
The acquisition of Leuna-Miramid GmbH, Leuna, Germany by BASF Aktiengesellschaft was completed November 1, 2005. The regulatory authorities issued their unconditional approval of the transaction.
Leuna-Miramid special...
Results from experiments conducted at the University of California, Santa Barbara may lead to profound changes in optical communications. The discovery is reported in the October 28th edition of the journal Science.

What happens when two atoms, each made up of an electron and its antimatter counterpart, called the positron, collide with each other? UC Riverside physicists are able to see for the first time in the laboratory that the...
Soft paper hankies are produced on huge rollers at a speed of up to two kilometers per minute. The roller surface has to be very flat and smooth. A new grinding machine works with micrometer accuracy and cuts downtime by...
Light can carry data at much higher rates than electricity, but it has always been too expensive and difficult to use light to transmit data among silicon chips in electronic devices. Now, electrical engineers at Stanfor...
In the annals of chemistry, there are many examples of hydrogen atoms moving from metals to carbon atoms. But no one has ever directly observed the reverse reaction — hydrogen atoms moving from carbon to a metal &m...
Using laser pulses that last just 70 femtoseconds (quadrillionths of a second), physicists have observed in greater detail than ever before what happens when atoms collide. The experiments at JILA, a joint institute of t...
