New group picture 🤩

Can’t recommend this enough. This particular series and the podcast including their patreon.

„What’s the origin of the complex exciton emission/absorption profile of 2D halide perovskites?“ I hear you asking. Join my early-bird (8:15 am 🥱) presentation tomorrow at #S25MRS to find out. Also stay for great talks by @aimsduke.bsky.social, Claudio Quarti and others.

Pictures from #HandsOff protests in New York (NY), Chicago (IL), Salt Lake City (UT), and St. Paul (MN). The opposition is waking up!

The Dutch famously don’t have a protest culture. What made me happy yesterday was to see many of our students join the protests. Several told me it was the first demonstration they had ever seen in Enschede. Hope this inspired many that democracy is more than voting.

Generationally the Millennials are a liberal democracy sandwich on Hitler bread.

I’m in Oxford to visit Marina Filip and talk about projects, but first things first 🤓

Yes, this happened. Chemistry is affected most badly, but also other departments. Most of the PIs that were laid off had active groups, were publishing, receiving grants, teaching, and doing everything else we are told to do to be seen as valuable members of the academic community /1

Dr. Pierre Lechifflart giving a fantastic talk about our work on excitons in 2D double perovskites at #nwophysics2025 #compchemsky

It was amazing to be involved in this collab. I’ve been dreaming about epitaxial halide perovskites since 2016, and now @mmoralesmasis.bsky.social can make them. Think of all the fun things that can be done with this 🥳

I can’t even begin to describe what David Lynch’s movies and, yes, Twin Peaks, mean to me. Opened a whole new world when I was in my early twenties. Beloved strangeness.

No 😢

To celebrate the debut of 2025, it's my pleasure to announce the next edition of our online PhD+ seminar series with talks by Clint van Hoesel from @tueindhoven.bsky.social and Fabian Lie from @utwente.bsky.social Subscribe for the Zoom link kncv-ctc-phdplus-seminars.nl @hybridlinn.bsky.social

Academic publishers: it is an absolute no-go to send a review request on 20 December with a deadline of 25 December, followed by an out-of-office message as a response to my email requesting time until 6 January.

Impressions from our festive end-of-the-year group meeting. Yes, bandstructures are excellent for holding Xmas decorations. You just need the right dispersion.

Group writing retreat with macarons, freshly imported from Paris by our own dr. Pierre Lechifflart (the one with the biggest smile 😀) #compchemsky

I finally got around to pulling some photos I took in the last year from my camera to my computer. Might upload some of them here. This is one of my favourites. From the northern Californian coast.

Good bye #f24mrs. I’m tired and inspired and pretty dizzy from the flu shot I just got. Had a great time here. Lots of new ideas and questions to think about. Thanks to @aimsduke.bsky.social, @feldmannlab.bsky.social and Paulina Plochocka for a great symposium on chirality and spin ✨

In a flurry of other things, I forgot to note that Rayan Chakraborty's groundbreaking (in my view) paper in JACS is out, showing how to design halide perovskites with drastically increased spin splitting: pubs.acs.org/doi/10.1021/... #compchemsky #chemsky #perovskites

Reliable #f24mrs highlight: APS reception and the view from the rooftop bar.

Hey #compchemsky #chemsky folks at #f24mrs: I’m gonna talk about our automized workflow for discovering spin-polarised halide perovskites tomorrow morning (and I’m scared because it’s all new, unpublished and unpolished 🫣).

Biggest takeaway from #f24mrs so far: chiral 2d perovskites are hot. So hot that the assigned room was too small this morning. Perovskites 2015 vibes.

Even as someone who really advocated for data driven approach to ED&I, I stand with a level of cynicism today because it FAILS those who CANNOT be captured and described with the required statistical power. It’s time to turn the focus on the workplace cultures pushing hard working women out. /5

On the train to the airport to fly to Boston for the MRS Fall meeting 💚

#compchem Good read: Embedded Many-Body Green's Function Methods for Electronic Excitations in Complex Molecular Systems #compchemsky doi.org/10.1002/wcms...

Today’s insight: just read your Parravicini before starting to work on any problem.

We were incredibly lucky today to have Rachel Woods-Robinson visiting our department and sharing her thoughts on sustainable material design with us. Main takeaway: this is an entirely new field, requiring a whole new level of interdisciplinary research #compchemsky #chemsky

Flagging for #Chemsky

I don’t think I’m ready for the new layout. Also, when is the APS going to join Bluesky?

Group meeting turned tutorial on Daan‘s automized phonon workflow turned treasure hunt for chromium isotopes. I love working with these people ❤️ #compchemsky

What kind of childhood makes a top scientist? Is it enough to have all the right traits (brilliance, grit, etc) or do you need the right family too? And why should we care? A 🧵 on our paper on the Nobel Laureates. A teaser: the income distribution of the laureates' fathers. 1/N

Thanks for the invite @zwijcompchem.bsky.social. Nice to be here!
