- 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...

- 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...

- 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...

- 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....

- 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...

- 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...

- Carbon Nanotube Bumps for Thermal and Electric Conduction in Transistor
- The continuous miniaturization of semiconductor chips has rapidly improved the performance of semiconductor products. However, thermal issues that affect semi- conductor chips are becoming more serious. For example, heat transfer has become a very serious problem in the CPUs of personal computers; high-frequency High-Power Amplifiers HPAs of mobile communication systems;...

- Filming nanotubes inside living animals
- A team of researchers at Rice University has filmed carbon nanotubes inside living animals. They've used a custom-built microscope and a technique called near-infrared fluorescent imaging to detect DNA-sized nanotubes inside living fruit flies. But more importantly, they've compared a group of fruit fly larvae fed with a yeast paste...

- The best of two nanoworlds
- As you probably know by now, carbon nanotubes show amazing mechanical strength, while metal nanowires show very interesting optical and electrical properties. Combining both has proved to be a challenge. But if it was possible, this would open the way to the use of carbon nanotubes in computer chips, displays...
