Thiazolidine‐Grafted Zeolite Imidazolate Frameworks: A Cysteine‐Derived Route to Improved Metal Loading and Tune the CO2 Hydrogenation Efficiency

open access: yesChemSusChem, Volume 19, Issue 1, January 2026.
Covalent grafting of S‐containing ligands onto a zeolitic imidazolate framework (ZIF) forms thiazolidine groups that bind noble metal ions, enhancing metal capture. The highly porous ZIF structure supports controlled growth of metal nanoparticles, while the specific interactions between the thiazolidine groups and metal atoms enable high metal loading ...

Automated and real‐time structure solution using 3D electron diffraction

open access: yesJournal of Applied Crystallography, Volume 58, Issue 6, Page 1986-1994, December 2025.
A fully automated, real‐time structure solution pipeline, Instamatic‐solve, has been developed by linking XDS and SHELXT to the continuous‐rotation electron diffraction method within Instamatic. Instamatic‐solve automatically handles data processing and structure solution right after data collection, providing real‐time assessments of data quality and ...
