What are three types of Swnts?

SWNT can be classified into three types; armchair, zigzag and chirality. Armchair and zigzag nanotubes are also known as achiral SWNT since its mirror image is identical to the original structure. The name of armchair and zigzag come from the shape of cross-sectional ring as shown in Table 3.1.

How did Iijima discover carbon nanotubes?

Using an electron microscope, in 1991 he discovered carbon nanotubes, a fourth-allotrope carbon solid (*1) that became a focus of international attention.

Who discovered CNTs?

Sumio IijimaCarbon nanotube / InventorSumio Iijima is a Japanese physicist and inventor, often cited as the inventor of carbon nanotubes. Although carbon nanotubes had been observed prior to his “invention”, Iijima’s 1991 paper generated Wikipedia

What is MWCNTs?

MWCNTs are the materials featuring predetermined functionality, thus forming an essential bridge between industrially useful graphite fibers of a micrometer size and fullerenes of a molecular size. From: Carbon Nanotechnology, 2006.

What are nanowires used for?

Nanowires are extensively used in nanoelectronic devices as connectors for the transportation of electrons. Cobalt, copper, silicon, and gold have been utilized to make nanowires. Chemical vapor deposition is used for the production of nanowires (Njuguna et al., 2014).

Who proposed carbon nanotubes?

Iijima
In 1991, Iijima discovered carbon nanotubes (CNTs). Since then, a new branch of knowledge in materials science has emerged – Nanoscience. In order to unveil the secrets of the innovative materials, hundreds of millions of dollars have been invested.

Who got Nobel Prize in carbon nanotubes?

Graphene – the perfect atomic lattice. A thin flake of ordinary carbon, just one atom thick, lies behind this year’s Nobel Prize in Physics. Andre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics.

What is a nanotube used for?

Applications of carbon nanotubes and their uses. CNTs are well-suited for virtually any application requiring high strength, durability, electrical conductivity, thermal conductivity and lightweight properties compared to conventional materials. Currently, CNTs are mainly used as additives to synthetics.
