A carbon-nanotube-infused ink for ink-jet printers first developed in the Rice Univ. lab of James Tour has been used to make thin-film transistors in radio-frequency identification tags that can be printed on paper or plastic. The transmitter can be invisibly embedded in packaging, instantly sharing far more information than a bar code.

The features on computer chips are getting so small that soon the process used to make them, which has hardly changed in the last 50 years, won’t work anymore. One of the alternatives that academic researchers have been exploring is to create tiny circuits using molecules that automatically arrange themselves into useful patterns.

Computers should not play dice. That, to paraphrase Einstein, is the feeling of a Univ. of Washington computer scientist with a simple manifesto: If you enter the same computer command, you should get back the same result.

Purdue Univ. researchers have developed a miniature device capable of converting ultrafast laser pulses into bursts of radio-frequency signals, a step toward making wires obsolete for communications in the homes and offices of the future.

Using large-scale supercomputer calculations, researchers have analyzed how the placement of metallic contacts on graphene changes the electron transport properties of the material as a factor of junction length, width and orientation. The work is believed to be the first quantitative study of electron transport through metal-graphene junctions to examine earlier models in significant detail.

At this week’s International Solid State Circuit Conference, IMEC and Holst Centre report a 2.4 GHz/915 MHz wake-up receiver which consumes only 51 µW power. This record low power achievement could open the door to battery-less or energy-harvesting based radios for long-range RFID or wireless sensor nodes.

As the U.S. population ages, manufacturers of consumer goods are realizing that many customers may not be as nimble-fingered or sharp-sighted as they once were. To help product designers and engineers address those changing requirements, researchers at the Georgia Tech Research Institute have been developing evaluation methods and design techniques to identify and address the needs of all consumers.

To meet the challenge of interpreting cell image data, a team of researchers developed a novel computational model to identify genetic interactions using high-dimensional morphological data. Integrating very basic prerequisite knowledge of a pathway, their model maps potential interactions within a network by looking for similar morphological features upon genetic perturbation.

A Princeton Univ. researcher has demonstrated a method that alters the properties of a lone electron without disturbing the trillions of electrons in its immediate surroundings. The feat is essential to the development of future varieties of superfast computers with near-limitless capacities for data.
