MatSus Spring 2026 Meeting in Barcelona

Wonderful as always to reconnect with friends from across the globe at this year's #MATSUS26 Spring Meeting @nanoge.org celebrating 10 years of #materials for #sustainable #development! :) Thanks to the D6 & C2 organizers for their kind invitations and see you all in Fall!

QuantSol 2026 Conference in Rauris

The 36th Conference on Quantum Solar Energy Conversion - QUANTSOL 2026 - in Rauris, Austria was an absolute highlight. Amazing place and people, highly recommend!

Costa Rica Energy Materials Conference 2026

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

The Impact of Chirality on Singlet Fission and Triplet Fusion: A Molecular Twist for Photon Management Chirality has recently emerged as a new means to profoundly impact the properties of organic semiconductors for spin-optoelectronic applications. Yet, a clear mechanistic understanding of chiral structure–property relationships remains absent to date, particularly for photon interconversion processes such as singlet exciton fission and triplet fusion. In this perspective, we highlight recent work that investigates chiral structures for these processes. We discuss the various ways in which chirality can impact such conversion processes and suggest ways to leverage it to improve photon management for both energy applications and quantum information science.

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;)

Outreach by the Feldmann Lab at EPFL making emissive quantum dots with high school students who present their results at poster session to the public

#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 !:) 👉

Very happy to show you around Villars when you are next around - even worth it in the summer, for hikes instead then!;) take care Volker:)

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

There is only EPFL

Giulio Cerullo's visit to EPFL

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

Pacifichem 2025 Conference in Honolulu

A wonderful Pacifichem 2025 Conference in Honolulu came to an end. A huge thanks to Steph, Tom, Ashlee, Zheng, Michael and Luca for the invitation to paradise! Mahalo!🌴

Yet another successful #team celebration 🎄🎅

Feldmann Lab Feuerzangenbowle 2025 and visit of Natalie Banerji

traditional Feuerzangenbowle and Secret Santa with special guest Natalie Banerji from Bern !:) 🔥🍷

Feldmann Lab Thanksgiving group photo 2025

Successful Thanksgiving celebration with our team, Wendy Queen’s, and our fantastic staff that help make our science dreams a reality every day 😊 #grateful

nanoGe Materials for Sustainability Conference 2025 Valencia Feldmann Lab

wonderful to catch up with friends across the globe at @nanoge.org MatSus Fall Meeting in beautiful Valencia! Proud of the rest of the team presenting their own research journeys to the community :))

🌟 Innovations in optoelectronics at #MATSUS25! From lead-free Sn nanocrystals and chiral perovskites to photodoping, spin/polarization tracking, ML-based characterization, and next-gen perovskite LEDs pushing the boundaries of materials science.
