Describe Some Uses of Nanotubes and Fullerenes

Fullerenes Carbon Nanotubes CNTs Graphene GR carbon nanofibers and carbon black are some of the different types of carbon NMs shown in Fig. Graphene is the basic structural element of carbon allotropes such as graphite charcoal carbon nanotubes and fullerenes.

These NMs are made of carbon content and come in a variety of morphologies.

If n and m are too small the structure described by the pair nm will describe a molecule that cannot be reasonably called a tube and may not even be stableFor example the structure theoretically described by the pair 10 the limiting zigzag type would be just a chain of carbons. Pores may be open or closed and pore connectivity and.

Science and Technology of Advanced Materials is the leading open access international journal covering a broad spectrum of materials science research including functional materials synthesis and processing theoretical analyses characterization and properties of materials. Nanoporous materials consist of a regular organic or inorganic bulk phase in which a porous structure is present. Through molecular-level design the two nanotube types were synthesized to have very small pore widths 047 nm for modified cyclic peptide nanotubes and 064 nm for m-phenylene ethynylene nanotubes.

That is a real molecule the carbyne. Emphasis is placed on the interdisciplinary nature of materials science and issues at. Nanoporous materials exhibit pore diameters that are most appropriately quantified using units of nanometersThe diameter of pores in nanoporous materials is thus typically 100 nanometers or smaller.

Which has some characteristics of nanotubes. Interestingly some researchers have reported the presence of fullerenes and CNTs in ambient air and indoor air samples concluding that they are generated at low levels from common flame combustion sources such as natural gas kitchen burners and automobile exhaust Lagally et al 2012 Aschberger et al 2010 Murr 2008. The carbon-carbon bond length in graphene is 0142 nm and these sheets stack to form graphite with an interplanar spacing of 0335 nm.
