At #ACSFall2026 in Chicago, sharing our current work in two talks on low-valent main-group organometallics and supramolecular coordination cages.
Great to reconnect with colleagues at the ACS Fall meeting.

Great to see Hellen @hellen_videa starting this new chapter in Namur with you, @Dr_Berionni!
Wishing her every success with B-YOND and in this next stage of her career.
All the best, Hellen!
Thrilled to welcome Dr. Hellen Videa (@hellen_videa) as PDRA in the group (joining the @ERC_Research project B-YOND). Former member of @GroupMartinez @CIQSO_UHU. 🧪
Huge thanks to Dr. Romain Losa for his outstanding postdoc work. Best wishes for your future academic career ! 👏
🔥We are on the cover of @angew_chem! A proud moment for the team!
✨Now featured as front cover of @angew_chem!
Well done @hellen_videa, with @keelan542 & @TobiKraemer.

Bravo! 🎓🎉
Congrats @adriancg94 from the whole group!
Also 🤜🤛 @LabPischel
🎓 New Dr in town! Congratulations @adriancg94 on a brilliant PhD defence!
Co-supervised with @LabPischel, his project brought together our Ga₂L₃ cages with DTE photochemistry.
Thanks to the committee: Prof. J. Hernando (UAB), Prof. A. Caballero (UHU) & Dr. M. Liras (IMDEA)
Now out in Structure and Bonding (@SpringerNature).
One periodic logic across the group: σ-donation Al(I) > Ga(I) > In(I), with Tl(I) restricted to Z-type/metallophilic behavior.
