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.

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 ...

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 ...

Systematic Evaluation of Polarizing Agents for Dynamic Nuclear Polarization Enhanced NMR
Angewandte Chemie, Volume 137, Issue 31, July 28, 2025.Thirty‐two polarizing agents consisting of dinitroxide and hetero biradicals are compared at magnetic fields of 9.4 T, 14.1 T, and 21.1 T, in organic and aqueous solvents. Their detailed enhancement factors, polarization build‐up times, contribution factors, and the resultant overall sensitivity gains are measured.

1,2‐Bis‐Triazenylarenes Enable Vicinal Sandmeyer‐Type Reactions
Angewandte Chemie, Volume 137, Issue 21, May 19, 2025.1,2‐Bis‐triazenylarenes enable vicinal disubstitution reactions. The reactions can be performed in one step or in a sequential fashion, and they allow introducing a range of different nucleophiles including fluoride, chloride, bromide, iodide, azide, hydroxide, methoxide, and acetamide.

Stability and performance of two GSBR operated in alternating anoxic/aerobic or anaerobic/aerobic conditions for nutrient removal [PDF]
, 2012 Two granular sludge sequencing batch reactors (GSBR) with alternating anoxic/aerobic (R1) and anaerobic/aerobic (R2) conditions were operated with a 4-carbon-source synthetic influent. The physical properties of the granular sludge were very good (SVI≈20
