How to make vertically oriented carbon nanotubes, and electrochemical capacitors that use such nanotubes as electrodesComposites that include carbon nanotubes (VACNTs) that are vertically oriented on the substrate are characterized by the composites containing additional chaotic carbon deposited on the outer...
It is amazing to think how a new technology like carbon nanotubes can make something as old and simple as a capacitor better. You have to wonder what other improvements will come as we understand these new materials even better. Continue reading“Better Capacitors Through Nanotechnology”→ Using ...

The latest development in carbon fiber technology is tiny carbon tubes called nanotubes. These hollow tubes, some as small as 0.00004 in (0.001 mm) in diameter, have unique mechanical and electrical properties that may be useful in making new high-strength fibers, submicroscopic test tubes, or ...
With the right arrangement of atoms, you can create a carbon nanotube that's hundreds of times stronger than steel, but six times lighter [source:The Ecologist]. Engineers plan to make building material out of carbon nanotubes, particularly for things like cars andairplanes. Lighter vehicles woul...
In this Review, we discuss sp2-hybridized carbon-based low-dimensional nanostructures, such as fullerene, carbon nanotubes and graphene, in the context of non-volatile memory devices and architectures. Applications of carbon nanomaterials as memory electrodes, interfacial engineering layers, resistive-...
The fibers created by the Rice lab of chemist and chemical engineer Matteo Pasquali consist of bundles of long nanotubes originally intended for aerospace applications where strength, weight and conductivity are paramount. The individual nanotubes measure only a few nanometers across, but when millions...
On the other hand, carbon nanotubes (CNTs) offer a unique combination of electrical, mechanical, thermal and optical properties that make them highly promising materials for numerous applications17–24. We have been investigating the use of laser-induced CNTs as a potent photothermal nanomaterial in...
The researchers have not built a complete prototype of a fuel cell with nitrogen-containing carbon nanotubes, and they have not estimated the cost to produce them. However, since carbon is abundant and cheap compared with platinum, the overall cost of the proposed design would likely be much le...
The tensile strength is said to be on the order of a hundred GPa, which is approximately a thousand times harder than steel [24]. These superior mechanical properties make carbon nanotubes suitable as reinforcing materials in composites. Andrews et al. [25] showed that by adding 5% of single...
