Identifying an Active Intermediate and Monitoring O─O Bond Formation in Water Oxidation by a Cobalt(III)‐TAML Complex

Angewandte Chemie International Edition, EarlyView.
Two redox tautomers of a cobalt–TAML complex show strikingly different reactivity in water oxidation. The ligand‐centered Co(III)–OH species evolves O2 via H2O2, while the metal‐centered Co(IV) = O is inactive. Electron‐transfer kinetics and the Marcus analysis reveal how redox localization influences reactivity and O─O bond formation in high‐valent ...

Visualization of Gaseous Ammonia Using an Ionic Liquid‐Based pH‐Responsive Dye

Analysis &Sensing, EarlyView.
An ionic liquid composed of bromocresol purple ([P66614]2[BCP]) is synthesized via an ion‐exchange reaction. The color of [P66,614]2[BCP] changes from yellow to blue after exposure to gaseous NH3. The color change in the [P66614]2[BCP] thin film serves as a visual indicator of pork and salmon decomposition.

Electromembrane Extraction for Multiclass Pesticide Assessment in Soil Matrices: Sustainable Analytical Insights

Analysis &Sensing, EarlyView.
The U‐shaped electromembrane extraction with liquid chromatography‐mass spectrometry enables rapid multiclass pesticide screening in soil. The 15 min, low‐solvent workflow achieves high recoveries and robust linearity, while AGREEprep and GAPI assessments highlight a greener profile compared to literature reports, which represents a smart strategy for ...
