The first on-chip visible light source using graphene as a filament has been developed by a team of scientists from Columbia Engineering, Seoul National University (SNU), and Korea Research Institute of Standards and Science (KRISS).
The scientists attached small strips of graphene to metal electrodes, suspended the strips above the silicon substrate, and passed a current through the filaments to cause them to heat… read more

Physicists at The University of Texas at Austin and colleagues in Taiwan and China have developed the world’s smallest semiconductor laser, a breakthrough for emerging photonic technology with applications from computing to medicine.
Miniaturization of semiconductor lasers is key for the development of faster, smaller and lower energy photon-based technologies, such as ultrafast computer chips, next-generation communication technologies, and highly sensitive biosensors for detecting, treating and… read more

Unlike other pen-sized scanners, which only scan a line at a time, ScanStik scans the whole page in one sweep, like a flat-bed scanner, in just four seconds, the company says.
It has a MicroSD memory slot, 24-bit/600 dpi resolution, rechargeable battery, USB connector for… read more

In another major new application of graphene, Columbia Engineering researchers have taken advantage of graphene’s special properties — its mechanical strength and electrical conductivity — to develop a nanomechanical system that can create FM signals — in effect, the world’s smallest FM radio transmitter.

Scientists have built an electric rotor with a gold blade 300 nanometers long. This sits atop an axle made from a multiwalled carbon nanotube; gold electrodes at either end of the axle lash the device to a silicon chip.
Applying a voltage between the nanotube and one of three more electrodes around it rotates the blade. The nanotube rotor can operate at great speed, over a wide range of… read more

It measures a mere 1 nanometer across (the current world record is a 200 nanometer motor).
According to E. Charles H. Sykes, Ph.D., associate professor of chemistry at Tufts, the team plans to submit… read more

The prototype is designed for use at home, using Internet blueprints to print custom 3-D objects. The desired object is printed in a small tub filled with synthetic resin.
The resin hardens under the illumination of intense beams of light. The synthetic resin is irradiated layer-by-layer at… read more
California Institute of Technology researchers have developed an electron microscope that can create real-time 3D images of molecules as they form and break apart in femtosecond reactions, using a modified transmission electron microscope interfaced with an ultrafast laser.

Nuclear plants are vulnerable to attacks by terrorists, according to a stark new warning by the International Atomic Energy Agency (IAEA).
The world’s 1300 nuclear facilities are not hardened to withstand “acts of war” like a deliberate hit by a large, fully-fuelled passenger jet, warns the IAEA’s director general, Mohamed ElBaradei.
In the US on October 29, following intelligence reports received by the FBI, the air space around all… read more

Imagine a clock precise to one second in a period comparable to the age of the universe (more than 13 billion years).
An international team led by the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory has proved how the world’s most powerful X-ray laser can assist in cracking the structures of biomolecules.
The team’s experiments used SLAC’s Linac Coherent Light Source (LCLS) to obtain ultra-high-resolution views of crystallized biomolecules, including a small protein found in egg whites called lysozyme.
For decades, scientists have reconstructed… read more
