Sustainable Water Decontamination: Advanced High‐Valent Iron Active Species‐Driven Peroxymonosulfate Activation for Global Challenges

CleanMat, EarlyView.
Iron‐based catalysts activate peroxymonosulfate (PMS) to generate high‐valent iron‐oxo species for water decontamination and clean water production. The activation efficiency of PMS varies significantly depending on iron catalyst properties, while the generation of reactive high‐valent iron intermediates is governed by catalyst characteristics ...

Deuterium NMR in Chiral Polymer‐Based Bimesophasic Lyotropic Mixtures: From the Demixing Process to Analytical Applications

Chemistry–Methods, EarlyView.
Bimesophasic lyotropic chiral systems are prepared from polypeptide and polyacetylene helical polymers in organic solvents. Combined with spatially resolved 2H nD NMR experiments, they provide a novel and original tool to collect independent sets of anisotropic quadrupolar data, with potential applications in chemistry dedicated to spectral ...

Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐
