Scientists at the Indian Institute of Technology (IIT) Bombay have developed an innovative hydrophobic graphene-based material to address the global freshwater crisis. With freshwater scarcity becoming a pressing issue worldwide, exacerbated by population growth and climate change, this advancement offers a promising solution. Although water covers much of Earth's surface, only about 3% is freshwater, and less than 0.05% is readily accessible. Desalination, the process of removing salt from seawater or brackish water, is a viable option but poses challenges in landlocked regions.
Led by Prof. Swatantra Pratap Singh, the research team created the Dual-Sided Superhydrophobic Laser-Induced Graphene (DSLIG) evaporator. This cutting-edge material can be powered by both solar heating and electricity (via Joule heating), making it versatile for various environmental conditions. The DSLIG evaporator enhances water purification efforts, potentially revolutionizing access to clean water in water-scarce regions.
