- Carbon nanotubes: Great for agriculture, but for humans?
- CNTs in agricultureChrisre: research into whether CNTs are safe for humans if ingested or used to improve seed strike or anywhere else in ag. You are correct about the potential risks, but as I read their paper, the researchers who found their tomatoes had improved propagation with CNTs are...

- Carbon nanotubes: Great for agriculture, but for humans?
- In what can eventually kick up a firestorm similar to the genetically modified food controversy, the emerging field of "nano-agriculture" is making headlines. It involves the use of nano-particles â€" wisps 1/50,000th the width of a human hair â€" in agriculture and could have beneficial affects for crops, say...

- Researchers give brain implants a nanotube coat to boost performance
- Microelectrodes implanted in the brain are increasingly being used to treat neurological disorders, but robust and reliable chronic application of neural electrodes remains a challenge. Scientists at University of Michigan have created brain implants tested in rats that can more clearly record signals from surrounding neurons. by Chris Jablonski

- Billion-year ultra-dense memory chip developed
- There's always been an inverse relationship between density and durability when it comes to data storage. Today's silicon memory chips contain a lot of density, but with a lifespan of just a few decades, they lack durability. Yet primitive forms of storage such as information carved in stone are highly...

- Researchers develop printable rubber-like OLED displays
- Researchers at the University of Tokyo have given new meaning to the term flexibility in the context of displays. They've developed of a stretchable display connected by organic light-emitting diodes OLEDs and organic transistors with a new highly-elastic conductor.

- Nanowires, nanoribbons and 'graphane' among materials that'll revolutionize computers
- Architects of the next generation of computers are developing a variety of nanostructures to meet the demand for increasingly smaller features for semiconductors, microprocessors, and other components. These tiny building blocks are quite extraordinary-some even self-assemble. And they'll help overcome many of the limitations of today's microelectronics...

- Nano-sized radio plays Eric Clapton’s "Layla"
- Accurately more nano than the iPod Nano, a radio built out of a single carbon nanotube that detects and plays songs was singled out in the latest issue of Scientific American as one of the first truly functional nanoscale devices that has a "measurable effect on the larger, macroscale world."...

- Small matters bringing huge change?
- H2O + CO2 with nanotubes= CH4 and O2. That's the basic formula of research done at Penn State. Scientists there make the hollow catalytic nanotubes from titania titanium dioxide. Each tube is 135 nanometres wide and a tenth of a millimetre long. The research at...

- Nanotechnology-based smart yarn for soldiers
- Chinese and U.S. researchers have developed a carbon nanotube-coated smart yarn which can conduct electricity and be woven into textiles to detect blood or to monitor health. According to one of the lead researchers, today's smart textiles, which are made of metallic or optical fibers, are fragile and not comfortable....

- Nanotechnology-based flexible actuators
- In 'Nanotube paper flexes on demand,' nanotechweb.org reports that French researchers are using multiwalled carbon nanotubes MWCNTs reinforced with polyvinyl alcohol PVA to develop ultra-lightweight actuators for aerospace applications. The scientists have developed a paper-like sheet which bends when the material is electrically stimulated. As said one of the lead...

- Nanoparticles used to trap oil drops
- Rice University researchers have found a new way to spontaneously assemble nanoparticles into bag-like sacs. Their 'nanobatons' could be used to clean up oil spills by trapping oil droplets in polluted waters. These nanoparticles could even be more useful for delivering drugs. The researchers found that 'ultraviolet light and magnetic...

- Passive Wireless Sensing Using SWNT- Based Multifunctional Thin Film Patches
- This study presents a high-performance inductively coupled multifunctional carbon nanotube thin film sensor for structural monitoring applications. A versatile layer-by-layer self-assembly sensor fabrication technique is employed to encode different sensing mechanisms (e.g., strain and corrosion/pH) within one homogeneous thin film structure. Judicious selection of various polyelectrolyte species, along with the...

- Year of the nanotube
- For nearly 25 years now, ever since the discovery of the Carbon-60 "Buckyball" at Rice University, scientists have been trying to find uses for what is now called nanotechnology. Those uses are now coming thick and fast. In November I wrote how carbon nanotubes could be...

- A nanotechnology award for NASA
- NASA is rarely associated with nanotechnologies. But one of its researchers working at the NASA's Goddard Space Flight Center just received a Nanotech Briefs Nano 50 award for a manufacturing process for high-quality carbon nanotubes CNTs. Because of its ability to produce bundles of CNTs without using a metal catalyst,...

- Repelling bullets with nanotube armors
- Australian engineers have found a way to use the elasticity of carbon nanotubes to not only stop bullets penetrating material but actually rebound their force. Their anti-ballistic carbon nanotubes are very different from the current materials used to design bullet-proof jackets, such as Kevlar, Twaron or Dyneema fibers. Current jackets...
