Speciation, Structural Refinement, and Distribution of Ti Sites in Titanium Silicalite‐1 From 47/49Ti NMR Crystallography at 28.2 Tesla

Angewandte Chemie, Volume 138, Issue 15, 6 April 2026.
Titanium silicalite‐1 (TS‐1), used in industrial selective oxidation processes, depends on specific, yet still unresolved Ti sites, dispersed within the framework of an MFI‐zeolite. Applying high field (28.2 T) 47/49Ti NMR and 17O NMR spectroscopy for an array of TS‐1 catalysts enables the development of an NMR crystallography protocol and the ...

Rapid Assignment of Chemical Shifts From Crystal Structures in Solid‐State NMR

Angewandte Chemie, Volume 138, Issue 14, 27 March 2026.
Chemical shift assignment in solids is a long and tedious process that relies on complex 1D and 2D NMR experiments. With prior knowledge of the 3D structure, this process can be significantly sped up by a Bayesian probabilistic assignment approach based on predicted chemical shifts.

Enhancing NMR Signals in Liquids by Fluorine‐19 Overhauser Dynamic Nuclear Polarization (DNP) and Hyperpolarization Transfer to Carbon‐13

Angewandte Chemie, Volume 137, Issue 50, December 8, 2025.
Fluorine nuclear spins can be hyperpolarized in solution by Overhauser dynamic nuclear polarization from a paramagnetic agent like galvinoxyl. This hyperpolarization can be transferred by nuclear magnetic resonance (NMR) to nearby 13C, leading to 13C signal enhancements up to ∼100.

Formation of Stable Amorphous Calcium Phosphate and Collagen Assemblies by a Versatile Spray‐Drying Approach

Advanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.

Backbone Engineering of Carbon‐Centered NHC‐Derived Diradicals: From Electronic State Tuning to High‐Performance Organic Field‐Effect Transistors

Advanced Materials, Volume 38, Issue 32, 8 June 2026.
The open‐shell nature of diradicals facilitates charge separation, and compounds with moderate diradical character demonstrate remarkable potential in organic field‐effect transistors (OFET) applications due to their low reorganization energies for hole and electron transport.

Unprecedented Selectivity for Arsenic(III) in a Dimercaptosuccinic Acid‐Based Zr‐MOF: The Role of Dangling Ligands

Angewandte Chemie, Volume 137, Issue 48, November 24, 2025.
Highly defective DMSA‐based zirconium metal–organic framework (Zr‐DMSA‐MOF) removes arsenic from water with higher selectivity over phosphate than conventional Zr‐MOFs. X‐ray absorption spectroscopy, pair distribution function analysis, and solid‐state NMR reveal that, unlike other Zr‐based MOFs where arsenic binds to the clusters, the flexible ...

Peptide‐Carbazolyl Cyanobenzene Conjugates: Enabling Biomolecule Functionalization via Photoredox and Energy Transfer Catalysis

Angewandte Chemie, Volume 137, Issue 32, August 4, 2025.
We introduce two methods for incorporating carbazolyl cyanobenzenes onto peptides: a C‐terminus decarboxylative functionalization and a Cys‐selective SNAr reaction. Both conjugates exhibit excellent photoredox/energy‐transfer properties, enabling their use for C‐terminal alkynylation and Cys‐selective thiol‐ene reactions on peptides, as well as ...
