IIT scientists develop material that can harvest water from fog
New Delhi, Oct 8 : Taking a leaf from nature's book, a team from IIT Mandi has developed a material that can harvest water from fog.
Researchers worldwide are working towards developing techniques that can harvest water from unexpected sources, such as fog and mist, to meet the burgeoning demand for water.
"There are several plants in arid and semi-arid regions of the world whose leaves can harvest water from dew and fog. If they can do it, so can we," said Venkata Krishnan, an associate professor at Indian Institute of Technology (IIT) Mandi, Himachal Pradesh.
For the study published in the journal ACS Sustainable Chemistry and Engineering, researchers studied the intricate structures on the leaves of an ornamental plant called the Dragon's lily head (Gladiolus dalenii).
The surface patterns on the leaf in micrometre and nanometre scales were evaluated in relation to the water harvesting properties, and the patterns were replicated onto a polymer material.
The team found a 230 per cent enhancement on the fog harvesting performance of the patterned samples, compared to an unpatterned control sample.
Solutions to provide drinking water to India's growing population must not only span policy and behavioural changes but also incorporate scientific and technological innovations inspired by nature, researchers said.

RJD surprise element in J’khand polls, party candidates leading in 5 of 6 assembly seats
Ranchi(PTI): The Rashtriya Janata Dal (RJD) has emerged as a surprise element in the Jharkhand assembly elections with its candidates leading in five of the six seats where the party is contesting, according to trends available on the Election Commission's website on Saturday.
RJD candidates in five assembly seats were leading over sitting BJP legislators.
In 2019, RJD had secured only the Chatra seat where its nominee Satyanand Bhokta won.
In Deoghar, RJD’s Suresh Paswan was leading by 19,581 votes over his nearest rival and BJP's sitting MLA Narayan Das after the third round of counting.
RJD’s Sanjay Prasad Yadav was ahead by 19,867 votes in Godda over BJP MLA Amit Kumar Mandal after the sixth round of counting.
In Koderma, RJD nominee Subhash Prasad Yadav, who was out on bail, was leading by a margin of 3,471 votes over BJP’s sitting legislator Neera Yadav.
Subhas Prasad Yadav, considered to be one of the close aides of RJD supremo Lalu Prasad, was recently granted bail by the Supreme Court in a money laundering case.
Party’s Naresh Prasad Singh was leading by 5,159 votes after the fourth round of counting over BJP’s Bishrampur MLA Ramchandra Chandravanshi.
RJD's Sanjay Kumar Singh Yadav was also leading from Hussainabad by 8,213 votes after the fourth round of counting over BJP MLA Kamlesh Kumar Singh.
Party’s candidate Rashmi Prakash, however, was trailing from Chatra by 3,776 votes.
Bhokta did not contest the elections this time, and his daughter-in-law Prakash was given a ticket.
