The dashing start of electrons in a crystal does not remain without consequences for their further fate. This is reported by the Berlin researchers Peter Gaal, Wilhelm Kuehn, Klaus Reimann, Michael Woerner, and Thomas Elsaesser of the Max-Born Institute and Rudolf Hey of the Paul Drude Institute in the latest issue of the magazine Nature (Vol. 450, Page 1210).
The U.S. Department of Energy (DOE) has granted "Critical Decision 2" (CD-2) status to the National Synchrotron Light Source II (NSLS-II). This decision approves the facility's performance baseline based on preliminary design, signifying a major step forward in the process to make this state-of-the-art research complex a reality.
PhotoMedex, Inc. announced today that it will supply private-label diode laser systems exclusively to AngioDynamics, Inc. to sell and market for peripheral vascular treatments.
As a step towards designing tomorrow's super-fast optical communications networks, a Duke University-led research team has demonstrated a way to transfer encoded information from a laser beam to sound waves and then back to light waves again.
The National Institute of Standards and Technology (NIST) has developed an imaging system that quickly maps the mechanical properties of materials - how stiff or stretchy they are, for example - at scales on the order of billionths of a meter. The new tool can be a cost-effective way to design and characterize mixed nanoscale materials such as composites or thin-film structures.
JDSU today announced that it has released the most powerful fiber-coupled diode laser solution with its next-generation L4 platform. The new telecom-grade solution leverages an innovative chip design to generate 10 watts (W) of output power. Its packaging takes up less space compared to previous designs, enabling original equipment manufacturers (OEMs) to pack more diode lasers into a smaller space within their systems.
Researchers at Rensselaer Polytechnic Institute have developed a new way to seek out specific proteins, including dangerous proteins such as anthrax toxin, and render them harmless using nothing but light. The technique lends itself to the creation of new antibacterial and antimicrobial films to help curb the spread of germs, and also holds promise for new methods of seeking out and killing tumors in the human body.
Seven new super-microscopes and a specially designed building will give scientists at DTU unique opportunities to design new materials. Among the areas that will benefit are the environment, manufacturing, energy and transport.
IBM researchers report a significant advance in the quest to send information between multiple cores - “brains” - on a chip using pulses of light through silicon, instead of electrical signals on wires.
One of the UK¡¯s largest planetary science departments is using its new Nikon LV-100D microscope to study dust collected by NASA¡¯s Stardust spacecraft during its fly-by of comet Wild-2. This fly-by was the first mission to return cometary particles to earth.
