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.

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.

OLED concept uses graphene as transparent conductor

Researchers at Stanford University have successfully developed a brand new concept of organic lighting-emitting diodes (OLEDs) with a few nanometers of graphene as transparent conductor. This paves th...

Thermopower waves draw big power from tiny wires

Thermopower waves draw big power from tiny wires

Carbon nanotubes with a special coating of reactive fuel can, when ignited, create a thermal wave that not only spreads quickly but also pushes electrons along the tube, creating a substantial electric current. The energy created by MIT engineers far exceeds that predicted by thermoelectric calculations.

Nanotube thermocells hold promise for converting waste to energy

A study reveals that thermocells based on carbon nanotube electrodes might eventually be used for generating electrical energy from heat discarded by chemical plants, automobiles, and solar cell farms.

Creating a graphene hybrid

Rice Univ. researchers have found a way to stitch graphene and hexagonal boron nitride (h-BN) into a two-dimensional quilt that offers new paths of exploration for materials scientists.

Graphene nanomesh could change the future of electronics

A team from UCLA revealed the creation of a new graphene nanostructure called graphene nanomesh, or GNM. The new structure is able to open up a band gap in a large sheet of graphene to create a highly uniform, continuous semiconducting thin film that may be processed using standard planar semiconductor processing methods.

Quantifying the electron transport effects of placing metal contacts onto graphene

Quantifying the electron transport effects of placing metal contacts onto graphene

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.

First woven fabric heater made from carbon nanotubes

First woven fabric heater made from carbon nanotubes

A Japanese company has woven conductive fabric made from highly-dispersed carbon nanotube multifilament yarns from Bayer MaterialScience, creating what could be the first fabric heaters to enter practical use: they have been successful tested on-board a train to keep water from freezing during a cold winter.

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.

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
