d‐Orbital Electron Spin Polarization Field Inhibits Photo‐Generated Carrier Recombination for Panel Photoelectrocatalysis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A solution‐processable sub‐nanocrystal of metal coordinated conjugated reticular oligomer with spin polarization functionality is employed as an active layer in planar photoelectrochemical water splitting. The rapid recombination of photo‐generated carriers remains a critical challenge limiting the photo‐electrocatalytic water splitting performance in ...

Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.

CO2‐to‐CO Electrochemical Conversion With an Fe(I) Porphyrin Complex in Water

open access: yesAngewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Using in situ UV–vis/IR spectroelectrochemistry, we track CO2 reduction by a water‐soluble iron porphyrin. Rather than the usual [Fe0] intermediate in organic solvents, CO2 binds the electrogenerated [FeI] species and undergoes reductive C─O cleavage to stable [FeII‐CO]. This previously unexplored reaction pathway is facilitated by an aqueous H‐bonding

Targeting peroxynitrite production in a model of persistent temporomandibular disorder comorbid with migraine

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 21, Page 6371-6385, November 2026.
Background and Purpose The persistence of temporomandibular disorders (TMDs), particularly myogenous, in a person with migraine can lead to exacerbated clinical outcomes and limited response to treatment. The pro‐nociceptive reactive nitroxidative species, peroxynitrite, is involved in migraine mechanisms, but little is known of its role in this ...
