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.

Scientists at the Biodesign Institute at Arizona State have hit on a new, versatile method to significantly improve the detection of trace chemicals. The technique—electrochemical imaging microscopy—was able to detect and identify TNT particles weighing less than a billionth of gram on the ridges and canals of a fingerprint.

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.

The Optical Society of America has highlighted an upcoming presentation at an annual optics conference San Diego in which the researchers from Germany will describe a method for encoding a wireless broadband signal through the light generated by a common household lamp. Visible-frequency signals have a tremendous advantage in bandwidth, and modulation would be so fast no one would notice the flickering.

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.
