Press coverage of Prof. K. Chattopadhyay Group’s research on mechanical behaviour of sea shells

We are pleased to note that several popular science media outlets have covered a recent paper from Prof. Chattopadhyay’s group in the journal Scientific Advances: Morphogenesis and mechanostabilization of complex natural and 3D printed shapes (by Chandra Sekhar Tiwary, Sharan Kishore, Suman Sarkar, Debiprosad Roy Mahapatra, Pulickel M. Ajayan, Kamanio Chattopadhyay).

Here’s a partial list:

The Hindu features Prof. Suryasarathi Bose’s Work

In the R. Prasad reports in The Hindu‘s Science and Technology page today: IISc: novel membrane filters water, kills bacteria. The report is about a recent paper from Prof. Suryasarathi Bose‘s group.

A low-cost water purification membrane capable of filtering out objects greater than one micron size and also killing E. coli bacteria has been developed by the Bangalore-based Indian Institute of Science (IISc) researchers and Steer Engineering Pvt. Ltd, Bangalore. The results of the study were published recently in the Journal of Materials Chemistry A.

The novel membrane with pores as small as 0.57-0.68 microns was developed by mixing two polymers — polyethylene (PE) and polyethylene oxide (PEO) — at 180 degree C. Unlike PE, PEO is water-soluble and the two polymers are immiscible.

“We want them to be immiscible as we want to remove one of them, in this case the PEO which is water soluble,” said Dr. Suryasarathi Bose, Assistant Professor, Department of Materials Engineering, IISc. He is the corresponding author of the paper. Tiny holes came into being once the water-soluble polymer was removed.
