Getting Started with CNTs

Back to the Top

Carbon nanotubes (CNTs) are sp^2 nanocarbon materials with tubular structures composed of rolled-up graphene sheets. In addition to unique nanostructures, they exhibit remarkable properties, some derived from the similar properties of graphite and some from their one-dimensional aspects. CNTs are chemically stable and resist virtually any chemical impact unless they are simultaneously exposed to high temperatures and oxygen. These advantages make CNTs ideal candidate for many applications(including electronic devices) such as:

  • Transistors

  • Electron-field emitters

  • Molecular electronics: CNT based non volatile RAM

  • Chemical/electrochemical sensors

  • Biosensors

  • Lithium-ion batteries

  • Hydrogen storage cells

  • Supercapacitors

  • Electrical shielding devices


Carbon Nanotubes

Single-walled carbon nanotubes (SWCNT) is a carbon nanotube made from one layer of carbon atoms. It can be formed in three different designs: Armchair, Chiral, and Zigzag. The design depends on the way the graphene is wrapped into a cylinder.

Double-Walled Carbon Nanotubes (DWCNT) is a class of carbon nanotube consists of two nanotubes, with one nested within the other. The differences in the diameters of the two nanotubes can produce varying degrees of interaction between the two tubes. This allows for modifications to be made to the outer nanotube without altering the inner nanotube's properties, and results in unique and interesting properties. Additionally, DWCNTs enable a combination of solubility and functionality (which is not possible with single-walled carbon nanotubes).


Double-Walled Carbon Nanotubes (DWCNT)

Multi-walled carbon nanotubes (MWCNT) is a carbon nanotube made consisting of several layers of graphene sheets. Multi-walled carbon nanotubes have similar properties to singlewalled nanotubes, yet the outer walls on multi-walled nanotubes can protect the inner carbon nanotubes from chemical interactions with outside materials. Multi-walled nanotubes also have a higher tensile strength than single-walled nanotubes.

LLTO is a lithium-ion oxide coating containing lanthanum and titanium.

LLGO is a lithium-ion oxide containing lanthanum and germanium.

Solid-State Battery is a battery technology that consists of a cathode composite layer, a sulfide solid electrolyte layer, and a carbon free micro-silicon anode. Before charging, discrete micro-scale Silicon particles make up the energy dense anode.

Bioinformatics is a field of computational science that has to do with the analysis of sequences of biological molecules. This usually refers to genes, DNA, RNA, or protein, and is particularly useful in comparing genes and other sequences in proteins and other sequences within an organism or between organisms, looking at evolutionary relationships between organisms, and using the patterns that exist across DNA and protein sequences to figure out what their function is.
