Me, a computationalist, writing the experimental part of a proposal:

Excellent Nobel Prize. My suggestion for next year: chemical engineering. Nobel himself was an engineer, and the prize awards achievements that "conferred the greatest benefit to humankind". Furthermore, the Prize should also be given to "improvements". When did that happen the last time?

Maybe the Prize is really about the friends we made along the way.

No mention of Jeff Long and family in the cited references is a bit disappointing...

"We propose that a new and potentially extensive class of solid polymeric materials with unprecedented and possibly useful properties..." Quite a strong opening line by Hoskins and Robson pubs.acs.org/doi/abs/10.1...

Check out my 'News & Views' on this exciting work, now out by invitation in Nature Chemistry @natchem.nature.com and available to read at rdcu.be/eJitR and www.nature.com/articles/s41...

โ€˜Completely shattered.โ€™ Changes to NSFโ€™s graduate student fellowship spur outcry The announcement comes months later than usual, leaving many would-be applicants stranded

This is no way to run a fellowship program. If eligibility rules were going to be changed, the NSF should have alluded to this earlier or not posted the original funding opportunity at all. It's a cruel thing to do to many of the nation's best and brightest.

I can't remember if you told me either, but here we are! Congrats again! This is all very exciting. So much fantastic science happening in Germany these days. Not a bad place to be.

I am thrilled, honored, humbled, excited (and nervous!) to announce that I have recently accepted a position in the Institute of Physical Chemistry at the University of Freiburg! As of this morning I am officially a resident of Freiburg, Germany and I am very excited to soon lead a lab of students!

Everyone always deserves to be treated with respect.

I recall invited talks where people treated me in a hostile manner. I think, while you might that you can make your point, you will cetainly make your institution look poorly

An accurate and efficient framework for modelling the surface chemistry of ionic materials - Nature Chemistry Simulating molecular adsorption on surfaces presents considerable challenges, as computational methods typically suffer from either insufficient accuracy or prohibitive computational costs. Now, with ...

A tough call? Cost vs speed. So congrats to Michaelides and all for their modelling work @natchem.nature.com that asks 'Why not both?' www.nature.com/articles/s41...

Today I added geometry optimisation, visualisation of the optimisation trajectories and animation of the vibrational modes (Hessian from finite differences) - hopefully that's enough (for now)!
