Progress in Characterizing Curing and Debinding of Ceramic Inks for Stereolithography
Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.ABSTRACT During ceramic stereolithography, laser photopolymerization must achieve high and uniform curing of monomers to ensure a crack‐free debinding step. In this study, we present a spatially resolved quantification of curing rate using Fourier transform infrared (FTIR) spectroscopy, relying on advanced deconvolution methods.

MOFs als neue katalytische Plattform für kovalente adaptive Netzwerke: Katalyse trifft Verstärkung
Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.Eine neu entwickelte, heterogene, katalytische Plattform für kovalente adaptive Netzwerke (CANs) wird vorgestellt. Dies wird erreicht durch die Immobilisierung von Basen mit geringem Molekulargewicht auf metallorganischen Gerüstverbindungen (MOFs). Der erhaltene Katalysator UiO‐TBD profitiert von der hohen Beladungskapazität von MOFs und demonstriert ...

MOFs as New Catalytic Platform for Covalent Adaptable Networks: Catalysis Meets Reinforcement
Angewandte Chemie International Edition, Volume 65, Issue 18, 27 April 2026.A novel heterogeneous catalytic platform for covalent adaptable networks (CANs) is introduced by immobilizing bases of low molecular weight on metal‐organic frameworks (MOFs). The obtained catalyst UiO‐TBD benefits from the high loading capacity of the MOF and demonstrates a higher thermal stability relative to free TBD.
