Despite all thorough understanding of the properties of CNTs, how to incorporate them in every day usage to satisfy our ever-hungry market is a challenge. When given an almost incredible material like CNT, what would you deal with these tubes? By virtue of their flexible usages and remarkable properties, CNTs are frequenters on assembly lines at present with their active part mainly in fields of both industry and daily life. Below are some examples.
World’s Smallest Motor
NTs, the team was capable of allowing the outer tube as well as the rotor to spin freely yet virtually without friction.
On one hand, when the stators were powered with up to 50 volts of direct current, the gold rotor bended up to 20 degrees, which could be detected by the SEM. On the other hand, the rotor acted much like a torsional oscillator, rocking back and forth, when treated with alternating voltage.
An oscillator as such, possesses the potential of conducting microwave frequency oscillations from hundreds of megahertz to gigahertz, was hopeful to be incorporating in other devices-especially, cell phones or computers and o
World’s Smallest Motor
It’s reported that the first nanoscale motor was created by a UC Berkeley physicist only about a decade after the engineers in University of California, Berkeley, built the first micro-scale motor. The nanoscale motor is a gold rotor on a nanotube shaft that could even ride on the back of a virus.
600 times tinier than the radius of a human hair, the motor is about 500 nanometers across. However, it’s the rotor, which is between 100 and 300 nanometers long, that rotates. The motor's shaft is a single MWNT. The rigid nanotube, which comprises nested nanotubes much resembles the l...

...sensitive and selective detection agents that can address the deficiencies of conventional technologies. Meanwhile, chemists are designing and fabricating new materials for application in diagnostic assays. Thanks to the revelation that nanotube electronic transport and thermo-power (voltages between junctions caused by inter-junction temperature differences) are very sensitive to substances that affect the amount of injected charge , and the minute size of the nanotube sensing element and the correspondingly small amount of material required for a response, possible chemical sensor applications of nonmetallic nanotubes are arousing attention. 
Despite the rosy outlook, major challenges remain. There are still difficulties exist in producing devices that differentiate between absorbed species in complex mixtures and provide rapid forward and reverse responses.

Synthesis of Carbon Nanotubes at Low Temperatures Using Single Heating Source of Catalyst and Reactor in the Floating Catalyst Chemical Vapor Depositi
- Abstract Synthesis of carbon nanotubes at low temperatures as low as 540oC was demonstrated via floating catalyst chemical vapor deposition method. Catalytic decomposition of benzene was employed using ferrocene as a catalyst precursor. In this work, the issue of introducing catalyst particles into the reactor has been developed by using single heating source for both the catalyst and reactor. In-situ monitoring device was used to observe the temperature profile in the reactor and thus, to initiate the reaction.... [tags: Research Analysis ]

- ... A chiral (n,m) nanotube has a spiral symmetry and the chiral angle is between 0° and 30°. Carbon nanotubes are not only structures that have the simplest chemical composition and atomic bonding conﬁguration, but also, at the same time, these structures have amazing properties which is the actual reason of them being studied. They have unparalleled electrical, mechanical and optical properties and show great thermal and electrical conductivity on the level of other conductive materials. Although they have negligible dimension, these structures are stronger than any other material.... [tags: carbon atoms, medical applications]

- High concentrations of arsenic are found naturally in groundwater worldwide and pose a potential health hazard to humans from long-term exposure. Arsenic exposure can come from drinking water, contaminated irrigated crops, and food preparation with contaminated water. The organic form of arsenic is less harmful than the inorganic form. The inorganic form of arsenic is present in groundwater and highly toxic, therefore hazardous to humans. Long-term exposure to arsenic in water can cause numerous health problems, primarily skin, bladder, and lung cancer.... [tags: groundwater, arsenic, carbon nanotubes]

TYPES OF CARBON NANOTUBES Single wall carbon nanotubes (SWNT) A sheet of graphite rolled into a tube with a singular cylindrical wall is called a SWNT. These are normally capped off at the ends. They have a diameter of close to 1nm. However they come in different lengths. One major advantage of the SWNT is that it can be twisted, flattened and even bent into small circles....

- Carbon fiber also has corrosion issues due to its chemical composition There are many different types of corrosions. According to Boeing Engineer David Banis, “Concentration cell corrosion, or crevice corrosion, is the most common type of corrosion found on airplanes” (Banis 2). It occurred whenever water is trapped between two surfaces, such as under loose paint, within a delaminated bond-line, or in an unsealed joint. The magnitude of the corrosion depends on the alloy that is used. Carbon fiber with metal mesh is susceptible to severe corrosion if not properly treated with the right sealant....

- Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. Their radius is generally in the range of a few nanometers. It is a hollow structure with the walls formed by one-atom-thick sheets of carbon, called grapheme, and thus belong to the fullerene structural family forming from a single structural component. The difference in the types of CNTs id formed on the basis of the specific angle at which the graphene sheet is rolled. Hence there are three types of nanotubes based on the rolling angle:- 1. Armchair 2. Zigzag 3. Chiral On the basis of number of CNTs encased:- 1. Single-walled nanotubes(SWNTs) 2. Multi-walled nanotubes (MWNTs) Properties Individual nanot...
