31. Which institute has developed lotus leaf-like solar evaporators for salt water treatment?
[A] IIT Kanpur
[B] IIT Roorkee
[C] IIT Bombay
[D] IIT Ahmedabad
Show Answer
Correct Answer: C [IIT Bombay]
Notes:
Scientists from Indian Institute of Technology (IIT) Bombay have developed lotus leaf-like solar evaporators called Dual-Sided Laser-Induced Graphene (DSLIG) for saltwater treatment. The material is made using polyvinylidene fluoride (PVDF) and polyether sulfone (PES), with graphene engraved using laser. DSLIG is superhydrophobic, meaning it repels water like lotus leaves, helping prevent salt from sticking on its surface. It uses both solar heating and electricity-based Joule heating, making it work even on cloudy days. It improves desalination by reducing heat loss and maintaining efficiency. It also works well with highly salty water and has low carbon footprint and toxicity.
