The final program of the MATSUS26 conference is out!📢. I will be presenting our latest work on doped conjugated polymers for thermoelectrics, along with top-researcher colleagues. @kuleuvenuniversity.bsky.social @erc.europa.eu

Today, I had the pleasure of sharing the role of external jury member with Mariano Campoy-Quiles during the PhD defense of Bram Bijnens from Uhasselt in organic bolometers for infrared detection. Congratulations to the new doctor and thanks to Koen Vandewal for the invitation.

Today we went for bowling and dinner afterwards. It felt so good to see the group enjoying some free time together out of the lab.

Congratulations to Dr Hasan Baysal! The 3rd graduate of the group and our expert in 3D printing and PEDOT:PSS aerogels! Thanks to the jury members and the funding agencies . @giorgiomattana.bsky.social @erc.europa.eu @kuleuvenuniversity.bsky.social

Always great to meet my friend and colleague @giorgiomattana.bsky.social from @itodys.bsky.social who came to @kuleuvenuniversity.bsky.social to serve as jury member for the PhD defense of Hasan Baysal. We are enjoying Belgium beer diversity.

Congrats to Bokai Zhang, the second PhD student to graduate from the group. He worked on brush-printed organic thermoelectrics. The first PhD graduates are instrumental in building the lab, both literally and culturally. Thank you! @kuleuvenuniversity.bsky.social; @erc.europa.eu

1st reunion of the Bao group Alumni yesterday in Zürich! It is great to catch up with such excellent scientists!

Thrilled to welcome Prof. Yang Yang’s research team from CAS to visit our labs at @kuleuvenuniversity.bsky.social and exchange research ideas. It was great to learn about deep sea exploration using flexible sensors in China. Quite impressive!

Grateful to my group member, Isidro Florenciano, for representing the group and @kuleuvenuniversity.bsky.social at the ECT25 conference in Nancy last week. He shared our latest results on laser-printed inorganic flexible thermoelectrics. @fwovlaanderen.bsky.social

We hosted LIMNI Summer School – NanoFabMat2025 participants in our lab @kuleuvenuniversity.bsky.social ! Great energy and a chance to showcase our latest research. Proud of the team & grateful to the organizers for including us in the program. @erc.europa.eu ; @fwovlaanderen.bsky.social

Keeping nice traditions. This year, we celebrate the 600th anniversary @kuleuvenuniversity.bsky.social with the University Trail. 10 km to discover the beautiful Arenberg campus, including going inside buildings! Here a team representing the Department of Materials Engineering.

Congratulations to Sachin and Nastasha on successfully defending their Master’s theses. Sachin worked on composites for wearable ultrasound devices, and Nastasha on inkjet-printed electrodes for organic PVs. Well done, both!

Big shoutout to Jean and Bokai for presenting at #ICOE2025 in Coimbra 🇵🇹!
