Chips made of Carbon Nanotubes to replace silicon chips soon

Researchers have developed a new technique to mass produce much tinier and faster carbon nanotubes that can replace silicon chips in computers. It could be possible to replace silicon with carbon nanotubes in manufacturing computer chips. It use would make the size of the computing components much smaller.

What are carbon nanotubes? What are the applications of carbon nanotubes?

  • Carbon nanotubes are allotropes of carbon (like diamond, graphite, grapheme etc.) with a cylindrical nanostructure.
  • Nanotubes have been constructed with length-to-diameter ratio of up to 132,000,000:1, considerably larger than for any other material.
  • They have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology.
  • In particular, owing to their extraordinary thermal conductivity and mechanical and electrical properties, carbon nanotubes find applications as additives to various structural materials. For example, nanotubes form only a tiny part of the material(s) in (primarily carbon fiber) baseball bats, golf clubs, or car components.


U.K. halts further aid to India

Buckling under mounting domestic pressure, imagethe British government declared stop to additional financial aid to India but all existent commitments until 2015 would be honored. 

  • The move would save Britain over £200 million over the next three years.
  • Britain’s new focus will be to offer technical help and investment in private sector poverty-alleviation projects
  • Move consequence to the economic crisis U.K. itself is facing and considering that India is ‘successfully developing’
