What a fantastic week in Costa Rica, as the International Conference on Energy Materials came to an end. A massive thank you to the organizers Monica Morales-Masis, Marina Freitag, Pablo P. Boix & Filippo de Angelis for the invitation to see a country that runs essentially 100% on #renewable

Check out our latest in @acs.org ACS Energy Letters: Damon explores how #chirality may impact singlet fission and triplet fusion in molecular semiconductors as a new twist for efficient photon management, boosting performance of solarcells, displays and more. #OpenAccess pubs.acs.org/doi/10.1021/...

Group social - Valais Carnival meets Bowling! We had a blast and I learned that a bowing lane in French is a “piste” just like for skiing;) #teambuilding #workhardplayhard

#Outreach - We had a blast hosting 3 high schoolers for the Swiss Study Week in Materials Science & Chemistry, organized together with Schweizer Jugend Forscht! They made some beautifully emissive quantum dots in the lab and presented their results to the general public. #EPFL

Impressions from an amazing faculty meeting invited by the Swiss Academy of Sciences on the beautiful Griesalp❄️

Thanks for letting us join for a small part in this! Check out these beautiful cages and their host-guest energy transfer !:) 👉

The team showing me how to ski was certainly a highlight of the month 😄

Impressions from Giulio Cerullo's seminar here at EPFL yesterday - an absolute spectroscopy master in action!
