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‐

Unfolding of the Villin Headpiece Domain: Revealing Structural Heterogeneity with Time‐Resolved X‐Ray Solution Scattering and Markov State Modeling

ChemPhysChem, EarlyView.
The unfolding of villin headpiece 35 (HP35) and a double‐norleucine variant (2F4K) using a temperature‐jump and time‐resolved X‐ray solution scattering is examined. HP35 displays a two‐state kinetic model, while 2F4K indicates a transient intermediate.

Electrocatalytic CN Coupling: Advances in Urea Synthesis and Opportunities for Alternative Products

ChemSusChem, Volume 18, Issue 12, June 17, 2025.
This review explores electrocatalytic urea synthesis via carbon–nitrogen (CN) coupling from CO2 and nitrogen species, specifically nitrate, nitrite, nitric oxide, and nitrogen gas. It discusses recent discoveries in catalyst design, reaction pathways, and detection methods. Future outlooks on industrial applications, alternative CN coupling products,

The Role of Metal–Organic Framework Induced Confinement Effects on Molecular Electrocatalysts Relevant to the Energy Transition

ChemSusChem, Volume 18, Issue 12, June 17, 2025.
In this review, the performance of a series of electrocatalysts confined in MOFs is compared to that of the corresponding homogeneous catalysts to evaluate to what extend the catalytic site is affected by confinement in terms of stability, activity and selectivity.

Mechanochemical Activation of NaHCO3: A Solid CO2 Surrogate in Carboxylation Reactions

ChemSusChem, EarlyView.
This study presents sodium bicarbonate (NaHCO3) as a safe, solid source of CO2 for mechanochemical carboxylation reactions. Mechanochemical methods for synthesizing cyclic carbamates and organic carbonates from NaHCO3 are developed. This approach holds significant potential for pharmaceutical applications, highlighting solvent‐minimized synthesis and ...
