A multinational staff of scientists has collaboratively developed a singular technique to show seawater into freshwater.
Inspired by how nature operates, scientists from Indian Institute of Technology (IIT) – Madras, Swinburne University of Technology ( Australia), and Delft University of Technology (the Netherlands) got here collectively to transform saline seawater into drinkable freshwater.
What did scientists do?
Using carbon nanotubes and graphene nanopores, the scientists improved on already recognized permeation capabilities of graphitic carbon supplies. The downside with earlier strategies was their tube-like construction, which bought in the way in which of permeation, all due to hydrodynamic resistance on the entrance of the tubes.
To repair this, scientists took a cue from nature. After observing the hourglass-like form of aquaporins, scientists launched a conical/hourglass-shaped inlet for water to cross via.

The passage of water via such a construction facilitates the separation of salts from the water, primarily based on which it was tried carbon nanomaterial-based membranes.
It’s all within the shapes
According to staff chief Professor Sarith P. Sathian, the examine has revealed hourglass-shaped nanopores assist in higher permeation of water, that means “identical mechanisms could be reproduced in a distinct system of nanopores which may present a better desalination effectivity.”
The examine additionally highlighted that “ion rejection is mainly depending on the CNT sizes” – implying a more practical desalination method could also be developed with out compromising on how a lot salt is rejected throughout the filtering course of.

The staff comprised Vishnu Prasad Kurupath from IIT Madras, Dr. Sridhar Kumar Kannam from Swinburne University of Technology, Australia, and Dr. Remco Hartkamp, Delft University of Technology, The Netherlands. The examine’s findings had been printed within the journal referred to as “Desalination” and first reported by Vigyan Prasar.
What do you concentrate on this unbelievable new strategy to deal with seawater, particularly given the risk to our freshwater sources attributable to to local weather change? Let us know within the feedback under.
