Detailed explanation-1: -Scientists at the Massachusetts Institute of Technology (MIT) have developed the biggest-ever computer chip using carbon nanotubes (CNT), instead of silicon, marking a milestone in computing technology, the Nature reported. The RV16XNano is a 16-bit processor that contains 14,000 transistors - electronic switches.

Detailed explanation-2: -The first carbon nanotube computer was built in 2013 by researchers at Stanford University. This one-bit processor, named Cedric, ran at 1KHz and contained just 178 transistors.

Detailed explanation-3: -Kureha Corporation, Shin-Etsu Chemical and Georgia Gulf are its global competitors. Founded in 1998, Carbon solutions company is based in California, US. It primarily aims to manufacture single-walled carbon nanotubes. They are also engaged in offering chemical solutions to their clients.

Detailed explanation-4: -In 1991, following the discovery and confirmation of the fullerenes, Sumio Iijima of NEC noticed multiwall nanotubes developed in a carbon arc discharge, and after two years, he and Donald Bethune at IBM independently observed buckytubes, that is, single-wall nanotubes.
