@gem-series.bsky.social
! We'll be starting tomorrow with a new mode: once a month 📅 but double the science! 🥼🧪
Kicking things off, we'll be hosting Matteo Degani &
@philipschulz.bsky.social
with a lot of new info on halide perovskites.
🌟 #GEMS is coming back next week, and we can’t wait to kick off our new format!
To get everyone back in the mood for cutting-edge energy research, we’ve just released Fanny Baumann’s talk from a previous session on YouTube 🎥⚡

Our new helium liquefier started operation yeterday! Liquid He can cool experiments down to a few Kelvin 🧊 but is both expensive and scarce. Replacing a 30-year old device, the liquefier contributes to a more sustainable way of doing science by recycling used He♻️

📢 In tomorrow's Physics Colloquium, we'll be hosting Hermann Kahle from University of New Mexico, who will be speaking on external-cavity surface-emitting lasers - join us for some insights into this exciting technology! Pew, pew!
Tea, coffee, and biscuits will be served from 3.15pm. ⏰
Hey folks! 🦄
The Nanochemistry and Spectroscopy Group at Lund University is looking for a postdoctoral researcher to help us push forward our studies on collective phenomena in nanomaterials: lu.varbi.com/en/what:job/...
At our physics colloquium the Chemnitzer Förderverein für Physik e. V. (represented by Prof Ulrich Schwarz) handed out awards for the best BA degrees in Physics and Sensors & Cognitive Psychology to Dorothee Boesler and Michaela Schreiber, respectively. Congratulations!
