Researchers at the Indian Institute of Technology Guwahati have formulated novel materials that can efficiently harvest water from humid air. A team of researchers led by Dr. Uttam Manna, Associate Professor, Chemistry Department and Centre of Nanotechnology, IIT Guwahati, has disclosed the results of their work in the journal of The Royal Society of Chemistry.
The team intellectuals include Mr. Kousik Maji, Mr. Avijit Das, and Ms. Manideepa Dhar.
IIT Guwahati said in a statement that scientists around the world are trying to receive and conserve water through non-traditional techniques.
In regions of the world with naturally scanty rainfall, plants and insects have devised ingenious strategies to pull and collect water out of the air. Mimicking this, scientists worldwide are trying to build technologies that can pull out water from thin air.
Such water-harvesting techniques utilize the theory of hydrophobicity or water-repelling nature of some materials, lead researcher Dr. Manna said.
IIT Guwahati said that their pitcher-plant-inspired SLIPS elements are improved to other bio-inspired ideas in terms of efficiency of water harvesting.

Apart from water harvesting, SLIPS could be used for other motives, such as easily cleanable household appliances, in underwater hulls of ships and submarines to prevent biofouling and anti-icing windows for aircraft.
