Nano-based RFID tags could replace bar codes

Nano-based RFID tags could replace bar codes

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.

Unexpected finding: Light can twist ribbons of nanoparticles

Unexpected finding: Light can twist ribbons of nanoparticles

In findings that took the experimenters three years to believe, Univ. of Michigan engineers and their collaborators have demonstrated that light itself can twist ribbons of nanoparticles.

DNA nanotubes offer promising applications in medicine

A team of McGill Chemistry Department researchers led by Dr. Hanadi Sleiman has achieved a breakthrough in the development of nanotubes—tiny "magic bullets" that could one day deliver drugs to specific diseased cells.

Solving hydrogen storage issues with layered graphene sheets

Solving hydrogen storage issues with layered graphene sheets

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.

Laser makes silicon pump liquid uphill with no added energy

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.

A golden bullet for cancer

A golden bullet for cancer

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.

Self-assembling computer chips

Self-assembling computer chips

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.  

Much ado about next to nothing

Much ado about next to nothing

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.

Testing century-old calculations

Testing century-old calculations

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.

Transforming polyethylene into heat-conducting material

Transforming polyethylene into heat-conducting material

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.

Lunar tires, space MRSA, and resonating microfluidics

Lunar tires, space MRSA, and resonating microfluidics

I typically attend the annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy each year in pursuit of specific coverage. This year, I sought out candidates for coverage in a vacuum technology article, and pulled together some instruments for a spectroscopy guide. But as busy as that kept me, it wasn’t all mass spectrometers and vacuum pumps on the show floor.

P2i showcases liquid repellent nano-coating for hearing aids
P2i showcases liquid repellent nano-coating for hearing aids

At the AudiologyNOW! 2010 show in San Diego next month, UK-based coatings company P2i will display their relatively new Aridion liquid-repellant nano-coating. Designed for exposure to humidity or sweat, the polymer layer is applied by a pulsed ion gas process that lower’s the hearing aid’s surface energy, coaxing water away from delicate components.

Submersible FlowCAM catches particle images and data in-situ and real-time

Fluid Imaging Technologies recently introduced its Submersible FlowCAM particle and cell imaging and analysis system at Ocean Sciences 2010 in Portland, Ore. The remote sensing platform can be used for continuous, unattended monitoring tethered to research vessels or autonomous submersibles.
