What is a Carbon Nanotube?
A carbon nanotube, which is the most popular type of nanotube at the moment, is a cylinder which has a wall of single graphite atoms. It is also know as Buckyballs or Buckytubes. It’s diameter is few nanometers (<6). A carbon nanotube has exceptional endurance due to its unique sp2 bonding structure. However, at a certain degree of pressure, the nature of the atomic bonding changes and this allows multiple nanotubes to link together and form a longer carbon nanotube chain. Nanotubes of this type are therefore exceedingly strong yet still flexible. Nanotubes made of graphite atoms also have distinctive electrical properties so they can become conductors or semi-conductors in turn. They can be used in the manufacture of capacitors; by using multiple layers, nanotubes become capable of holding electrical charge. They can also be used in the manufacture of resistors and transistors. Multiple cylinders of a single nanotube have been found to work well together. The inner cylinder can actually rotate or move inside the outer cylinder without much resistance from the latter. This characteristic can be applied to make special microscopic rotors. Nanotubes have an amazing potential in a wide variety of fields such as electronics engineering (especially in the manufacture of microscopic chips), optical technologies, nanotechnology, and materials engineering.

How are various companies manufacturing Nanotubes?
There are several approaches to the commercial manufacture of carbon nanotubes. They include the arc discharge method, the laser-aided vaporization method and the chemical vapor deposition (CVD) method. The arc discharge method has been accidentally discovered in 1991 when carbon nanotubes were found in the residue of an electrical arc discharge. The laser-aided vaporization method (commonly known as the laser ablation method) involves a graphite board that's enclosed within a high-temperature reactor chamber. A laser is then activated and the graphite board is consequently vaporized. All the while, a non-reactive gas is allowed to escape into the reactor chamber. The vapor inside the chamber is then allowed to cool and carbon nanotubes are formed in result. The CVD method involves a substrate layer on which surface lie catalytic metal particles. The substrate is placed inside the reactor and heated while two types of gas are fed into the reactor. As the carbon-containing gas passes over the heated metal particles, pure carbon is separated from its base compound and carbon nanotubes are formed.

What are the physical properties of CNTs?
SWCNT’s have reported tensile strengths 20 times that of steel with 1/6 the weight. In addition, carbon nanotubes significantly improve the electrical and thermal conductivities of commercial polymers. Carbon nanotubes offer the ability to enhance the mechanical and structural properties of composites. The conductivities of CNT’s composites are at least several orders of magnitude higher than those of CNT’s composites, particularly at low nanotube loading levels.

Does NANOSHEL™ make products with nanotubes? Who use NANOTUBES?
NANOSHEL™ does not manufacture products with nanotubes. We manufacture Nanotubes of different kinds. We have identified a significant number of worldwide Customers for both SWNTs and MWNTs, and have supplier relationships of nanotubes with many of them. Our business is to make nanotubes easier to process and use in products, and to help our customers pick the right nanotubes and the right processes for their application. Since we are not obligated to use a particular type of nanotube or manufacturing technology, we objectively pick the optimal manufacturer for a particular application.

What is the Health risk of Nanotubes if inhaled?
Nanotechnology is a rapidly advancing industry with many new products already available to the public. Therefore, it is essential to gain an understanding of the possible health risks associated with exposure to nanomaterials and to identify biomarkers of exposure. In humans and in other living organisms, they may move inside the body, reach the blood and organs such as the liver or the heart, and may also cross Cell membranes. Inhaled nanoparticles can deposit in the lungs and then potentially move to other organs such as the brain, the liver, and then spleen possibly the foetus in pregnant women. Some materials could become toxic if they are inhaled in the form of nanoparticles. Inhaled nanoparticles may cause lung inflammation and heart problems.
