It is that time of the year --> Exam correction 🤯 That feeling when you start, followed what it looks like the students want to do to your mood 😱 Unit conversion seems to be the main reason they lose points...

Super proud of this work! Epitaxial growth of halide perovskites at room temperature by PLD: Beautiful reciprocal space maps 🤩, nice strain calculations by @hybridlinn.bsky.social 💫 and co., and optoelectronic characterization together with Czech Acad. Sci., AMOLF and U. of Oxford. #ERCStGCREATE

I wish editors gave a page count when they ask you to review something. I might not have the time to review a 15-page monster but could deal with a shorter article!

Celebrating the end of my teaching duties this semester with a nice beer and a nice movie! Happy to be done 😅

Next time, I take over a lecture to help a colleague. I hope it won't be the last of the semester! Having to ingest a full course in 3 days is not fun 😅 I haven't thought about what "curl" is or how to derive Maxwell's equation in 10 years 🤯

The main feedback from the student evaluation: a 4h lecture block is too long! I could not agree more 😂
