• IIT Guwahati researchers have developed a silica nanoparticle-coated cotton fabric that can separate oil from an oil-water mixture.
  • The nanoparticles are made from rice husk, an agricultural waste, and coated on the fabric to make it water-repellent and oil-absorbent.
  • The innovation aims to convert waste biomass into a useful product by producing sustainable microalgae biofuel from wastewater and microalgal biomass using hydrothermal liquefaction and reduce oil spills.
