Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

For the Few, Not the Many: Tracing the Residualist and Compensatory Nature of British Energy Support

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Drawing on extensive documentary analysis, this article traces the evolution of British energy policy support since World War II. It analyses shifts in policy design through two interpretive lenses: eligibility (residualist vs. universalist) and function (compensatory vs. preventive).

Validation and Application of an HPLC–UV Method for the Quantification of 3‐O‐Methylquercetin in Nasal Mucosa

open access: yesELECTROPHORESIS, EarlyView.
This study improved an HPLC–UV method for quantifying 3‐O‐methylquercetin in porcine nasal mucosa following ICH M10 and ANVISA (Brazil) guidelines, assessing selectivity, linearity, accuracy, precision, and robustness. The method was applied for the first time to evaluate release, permeation, and retention profiles of a nasal formulation.
