More in news
  • Black Carbon Soot:
    (1) Fine black particles, chiefly composed of carbon, produced by incomplete combustion of coal, oil, wood, or other fuels.
    (2) Soot can consist of acids, chemicals, metals, soils, and dust.
    (3) Emitted from gas and diesel engines, coal-fired power plants and other processes that involve burning of fossil fuel and known to be highly carcinogenic.
  • What has scientists transformed:
    (1) Scientists have converted black soot into graphene nanosheets.
    (2) Utilized the nanosheets to remove organic dyes such as crystal violet, rhodamine B, and methylene blue from industrial waste.
    (3) Black soot is available everywhere and even a lay person can convert it into graphene nanosheets at home.
