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.

Inappropriate for MLAs seeking free IPL tickets, says D.K. Suresh
Bengaluru: Bengaluru Milk Union Ltd President D.K. Suresh on Monday said it is inappropriate for MLAs to seek free IPL tickets, adding that those interested in watching matches should pay for them personally.
Speaking to reporters near his residence in Sadashivanagar, he said, “IPL is a commercial tournament and does not represent the country. It is not right for public representatives to focus too much on such matters.”
Referring to the recent controversy during the RCB celebrations, he said, “let us find out who benefited the most from the statements made during the incident.” He also pointed out that BJP MLAs had received IPL tickets as well.
Responding to discussions about relocating the Chinnaswamy Stadium, Suresh said the government has already approved the construction of a new stadium at a location he had proposed.
“I had suggested building a stadium in Surya City and submitted a proposal for it. Bengaluru needs four stadiums in four directions to cater to its growing population and encourage youth participation in sports,” he said.
He noted that apart from Kanteerava Stadium, KSCA, and the Football Stadium, there are limited facilities in the city.
“When I was a Lok Sabha member, I had proposed allocating 100 acres in my constituency at Surya City. The land was later earmarked and the plan approved,” he added.
Suresh said he has discussed the project with Minister Zameer Ahmed Khan, Rajiv Gandhi Housing Corporation Chairman Shivalingegowda, and Anekal MLA Shivanna.
“The Cabinet has now approved the project, and a stadium will be developed on around 50–60 acres,” he said.
He further added that he has requested the Deputy Chief Minister to build another stadium at Shivarama Karanth Layout through the BDA, where 40 acres have been allocated. Plans are also being discussed to develop a well-equipped stadium in Bidadi.
Commending state government's recent bilingual policy move, Suresh said forcing children to learn three languages could affect their comprehension.
“It is a good decision to make two languages compulsory. Learning a third language should be left to the choice of students and parents,” he said.
Responding to criticism from BJP leaders, he said their tendency is to oppose every decision of the government.
“To please their central leadership, they take a pro-Hindi stance. Instead, they should advocate for the adoption of Kannada in all states,” he said.
When asked about the earlier three-language policy under Congress, he said, “the situation is different now. Today, the focus should be on quality learning. Kannada should remain the primary language, while students and parents can choose an additional language.”
