How are carbon nanotubes classified?
How are carbon nanotubes classified?
In addition to the two different basic structures, there are three different possible types of carbon nanotubes. These three types of CNTs are armchair carbon nanotubes, zigzag carbon nanotubes, and chiral carbon nanotubes.
Is carbon nanotube a chemical?
Carbon nanotube chemistry involves chemical reactions, which are used to modify the properties of carbon nanotubes (CNTs). CNTs can be functionalized to attain desired properties that can be used in a wide variety of applications.
What is carbon nanotubes made of?
What are carbon nanotubes? Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene).
What element are carbon nanotubes?
carbon atoms
carbon nanotube, also called buckytube, nanoscale hollow tubes composed of carbon atoms. The cylindrical carbon molecules feature high aspect ratios (length-to-diameter values) typically above 103, with diameters from about 1 nanometer up to tens of nanometers and lengths up to millimeters.

Are carbon nanotubes biodegradable?
Summary. Many studies have shown that CNTs can be biodegraded by macrophages through enzymatic oxidation. Neither CNTs undergoing biodegradation nor the byproducts of their degradation have been reported to be cytotoxic in vitro and in vivo.
How carbon nanotubes are formed made?
A sheet of graphene of one atom in thickness is rolled into a tube. This creates a single-walled carbon nanotube. Other than this, layers of these graphene sheets can be rolled in order to create multi-walled carbon nanotubes, which have slightly different properties.
How does carbon nanotubes formed?
The fullerenes and CNTs are formed by plasma arcing of carbonaceous materials, particularly graphite. The fullerenes or carbon nanotubes appear in the soot that is formed, while the CNTs are deposited on the opposing electrode.
What is the chemical structure of carbon nanotubes?
The structure of a carbon nanotube is formed by a layer of carbon atoms that are bonded together in a hexagonal (honeycomb) mesh. This one-atom thick layer of carbon is called graphene, and it is wrapped in the shape of a cylinder and bonded together to form a carbon nanotube.
What is the chemical formula for carbon nanotubes?

How carbon nanotubes are formed made and explain?
In the CVD process, manufacturers can combine a metal catalyst (such as iron) with carbon-containing reaction gases (such as hydrogen or carbon monoxide) to form carbon nanotubes on the catalyst inside a high-temperature furnace. The CVD process can be purely catalytic or plasma-supported.
Can carbon nanotubes be made into artificial blood capillaries?
Carbon nanotubes can be made into artificial blood capillaries for an injured part of the human body as they are promising drug delivery platforms that can be functionalized with a variety of biomolecules, such as antibodies, proteins, or DNA.
Do carbon nanotubes occur naturally?
Although it is generally assumed that carbon nanotubes are naturally occurring, there is surprisingly little evidence to support this assumption1.
Are carbon nanotubes biomaterials?
CNTs have been widely researched and developed as biomaterials that can offer high function, performance, and durability in orthopedic applications.
