3 papers got accepted on a day! This is the highest amplitude so far for us😂. One in JACS, one in Chemical Science and the third in ACS Sustainable chemistry and Engineering.
Here is the asap version of the JACS paper.

Check out our latest paper in JACS! Here we show for the first time that two different polymers can be made from a monomer! Only nature could do this, till date ( e.g. cellulose and starch are polymers of glucose)!

A quarter century!
Here is our 25th paper in Angewandte Chemie!
Achieved in a span of 12 years, all from IISER Thiruvananthapuram. 13 PhDs graduated.
Every student who graduated from the group had at least one paper in Angewandte Chemie.
Credits to them!

Here is our 24th paper in Angewandte Chemie!
In this paper we show that packing frustration in a set of structurally similar monomers leads to z’>1 in their crystals, which in turn lead to the formation of polymer-blends upon topochemical polymerisation.

Absolutely! In a PhD student, I am not just looking for pair of working hands. I train students for refereeing papers, grant proposals, writing grants, etc. I can finish writing any paper in a week, but I dont do. All students are not same; some good results are still unpublished
Many students/postdocs are great in the lab but have problems in putting together a starting draft for a manuscript. For many PIs this is good enough, as they basically write the whole story. I say no, this is not good enough, and PIs must spend time to train them how to write!

Rosalind Franklin, the real brain behind the discovery of the double helical structure of DNA
Happy birthday Rosalind Franklin (1920 – 1958), chemist & x-ray crystallographer whose x-ray diffraction images were instrumental to discovering double-helix structure of DNA, made important contributions to carbon & virus research, was 1 of great scientists of 20th century.
