This is very clever! Put a MOF particle on an AFM tip, dunk it in polymer solution, then see how sticky the tip now is - repeat and you can get a polymer uptake isotherm on a single particle. Love the idea.

all academic applications should have consolation prizes.

This is an interdisciplinary project where you get to do coordination chemistry with bismuth and zinc, as well as some microbiology and some computational chemistry - all in the name of combatting antimicrobial resistance.
Currently UK only.

In the latest publishing madness, I had a manuscript returned to me because it scored >15% in a 'similarity test'. On careful inspection, it was mostly matching the published thesis of one of the authors containing the results, and our own previous related study published in the same journal.

They're also responsible for one of the best emails I've ever received, when the college office sent out a plea for sightings of Professor Biscuit while conveniently forgetting to mention that he was a cat...(I won't comment on how often a similar email might have gone out about human Professors...)

In the spirit of #ChemChat, here is one of my favourite bits of physical chemistry out in the real world: the 4th century Roman Lycurgus Cup.
Green in reflection, red in transmission, due to gold/silver nanoparticles in the glass, I finally got to see it for real a few weeks ago. Beautiful.

I have recently added #ChemChat as a feed thanks to @stephy.bsky.social (and to @chemjobber.bsky.social for the concept)

Google Scholar has introduced a 'Sh-index' metric that scores papers higher if you are first or last author. Apart from the fact metrics are generally bad, this one explicitly punishes PIs who often collaborate, publishing with 2 or 3 equal PIs at the end of the list.

Researchers welcome the initiative, but say it doesn’t go far enough to capture the nuance of researcher productivity and impact.
