Mechanistic Divergence in Sulfur‐Ligated Iron(III)‐Alkylperoxo Reactivity: Aldehyde Oxidation Prevails over Deformylation

Angewandte Chemie, Volume 137, Issue 43, October 20, 2025.
This study explores the mechanistic investigation into an unusual reactivity of a thioether‐ligated low‐spin Fe(III)‐alkylperoxide with cyclohexane–carboxaldehyde as a mimic of nonheme iron(II) enzyme intermediates and highlights that only efficient catalysis happens from a high‐valent iron(IV)‐oxo species.

Parameter Estimation in Land Surface Models: Challenges and Opportunities With Data Assimilation and Machine Learning

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract Accurately predicting terrestrial ecosystem responses to climate change over long‐timescales is crucial for addressing global challenges. This relies on mechanistic modeling of ecosystem processes through land surface models (LSMs). Despite their importance, LSMs face significant uncertainties due to poorly constrained parameters, especially ...

Existence of Hydra Effect in a Three‐Species Food Chain Mathematical Model With General Holling Type Response Functions

Natural Resource Modeling, Volume 38, Issue 4, November 2025.
ABSTRACT This study explores existence of hydra effect and sustainable harvesting strategies in three species food chain system with all‐purpose Holling type response functions (HT‐I, II, III, and IV). The hydra effect (as mentioned in Sieber and Hilker 2012) is superficially ecological paradox which refers to an increase of a species population size ...

The Odd Couple: Oxidative Coupling of an Iridium(III) Phenylimido Complex

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 15, October 21, 2025.
The odd couple: In situ generation of a nitrenoid iridium(III) imido complex is reported, which is inherently unstable towards oxidative para‐C–C coupling. Catalytic arylnitrene transfer often results in catalyst decay via aromatic coupling reactions.
