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.

Graphene—carbon formed into sheets a single atom thick—now appears to be a promising base material for capturing hydrogen, according to recent research at the National Institute of Standards and Technology (NIST) and the Univ. of Pennsylvania. The findings suggest stacks of graphene layers could potentially store hydrogen safely for use in fuel cells and other applications.

Researchers at the Univ. of Rochester's Institute of Optics have discovered a way to make liquid flow vertically upward along a silicon surface, overcoming the pull of gravity, without pumps or other mechanical devices.

Magic bullets, also called silver bullets, because of the folkloric belief that only silver bullets can kill supernatural creatures, remain the goal of drug development efforts today. A team of scientists at Washington Univ. in St. Louis is currently working on a magic bullet for cancer. But their bullets are gold rather than silver.

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.

The recent review of the past 10 years of the National Nanotechnology Initiative--as presented by the President's Council of Advisors on Science and Technology--suggested the rise of nanomanufacturing as the near future of nanotechnology. But the actual proposed funding reflects a cautious approach, even about nanotech in general.

Calculations are fine, but seeing is believing. That's the thought behind a new paper by Rice Univ. students who decided to put to the test calculations made more than a century ago.

Most polymers—materials made of long, chain-like molecules—are very good insulators for both heat and electricity. But an MIT team has found a way to transform the most widely used polymer, polyethylene, into a material that conducts heat just as well as most metals, yet remains an electrical insulator.
