Other tech: quantum encryption over fiber at 4 Mbps

The laboratory system produced this “raw” key at a rate of more than 4 million bits per second (4 million bps) over 1 kilometer (km) of optical fiber, twice the speed of NIST’s previous record, reported just last month.** The system also worked successfully, although more slowly, over 4 km of fiber. The record speed …

Paint on quantum dot lasers

Researchers at the University of Toronto have created a laser that could help save the $200-billion dollar computer chip industry from a crisis expected in 2010 dubbed the “interconnect bottleneck.” To tackle this problem, Ted Sargent, a Canada Research Chair in Nanotechnology, created the new laser using colloidal quantum dots — nanometre-sized particles of semiconductor …

Other tech: artificial gill closer

Artificial Gills: One Big Stroke Closer To Reality The key to artificial gills, explains Harihara Baskaran, an engineer at Case Western Reserve University, is getting water to flow easily through microchannels, which mimic a real gill. Working with Infoscitex of Waltham, Mass., Baskaran is using chipmaking techniques to create tiny devices with hundreds of channels. …

other tech: new robotic military vehicle, Crusher

“Crusher,” a 6.5-ton, six-wheeled robotic vehicle designed to negotiate harsh terrain, will be presented along with its predecessor, “Spinner,” at Carnegie Mellon’s National Robotics Engineering Center on April 28, spokeswoman Anne Watzman said. Although Crusher is designed to carry weapons, the university has worked only on the machinery of the vehicle, Watzman said. Crusher combines …

Larger nanoscale: Improved electrospinning

Techniques improved could be useful on smaller scales. Daoheng Sun and Liwei Lin’s at the university of Berkeley have improved electrospinning. They enable fibers ranging from 50 to 500 nanometers in diameter to be deposited onto a collector plate in a directed, controlled manner. In reference to the shortened distance between the ejector and collection …

Light powered engine added the 4 nanometer long Rice University nanocar

This work is continued refinement of increasingly complex and useful nanodevices. Light powered engine added the 4 nanometer long Rice University nanocar The car’s light-powered motor is attached mid-chassis. When struck by light, it rotates in one direction, pushing the car along like a paddlewheel. There is other coverage at cnetThe nanocar consists of a …
