The nano science of kajal
Ask the millions of women who routinely ring their eyes with kajal about nanotechnology, and chances are you would receive a vacant stare in return. Just the other day, the Indian Institute of Technology, Kanpur, announced that kajal constituted carbon nano tubes (CNT). So? Now consider this: till now the generation of CNT was an expensive affair in which an organic compound like benzene was vapourised and CNT extracted from the deposition of the smoke. The equipment used in the process alone costs over Rs 10 lakh. And how much does it cost to burn oil in an ordinary lamp and catch the soot on a plate—the way kajal is made at homes all over India?
