Prelims: Current events of national and international importance. 
Mains: GS III- 

  • Science and technology- developments and their applications and effects in everyday life.
  • Awareness in the fields of IT, Space, Computers, robotics, nanotechnology, biotechnology. 

Features: 

  • The material is made from vertically aligned carbon nanotubes, or CNTs -microscopic filaments of carbon that the team grew on the surface of a chlorine-etched aluminum foil.
  • The foil captures more than 99.96 percent of any incoming light, making it the blackest material on record, according to the findings published in the journal ACS-Applied Materials and Interfaces.
  • The CNT material may be of practical use, for instance in optical blinders that reduce unwanted glare, to help space telescopes spot orbiting exoplanets.
