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

Confined Hot Carrier Cooling Via Excited‐State Energy Gap Engineering in Graphyne Carbon Allotropes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The excited‐state energy gap (EEG), regulated by the concentration of sp‐hybridized carbon, provides an effective handle for tuning electron–phonon coupling behavior. This design enables long‐lived confinement of hot carriers near the top of the EEG with controllable energy levels.

The “Magic” of Conflict: How Participatory Governance Can Enable Transformative Climate Adaptation

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT In many cases, addressing climate risks requires transformative climate adaptation (TCA) that goes beyond small adjustments to existing systems. While scholars increasingly argue that participatory governance is key and should embrace conflict rather than push for consensus to enable TCA, this assumption remains underexplored.

Myocardial inflammation is associated with impaired mitochondrial oxidative capacity in ischaemic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1246-1255, April 2025.
Abstract Aims Myocardial inflammation and impaired mitochondrial oxidative capacity are hallmarks of heart failure (HF) pathophysiology. The extent of myocardial inflammation in patients suffering from ischaemic cardiomyopathy (ICM) or dilated cardiomyopathy (DCM) and its association with mitochondrial energy metabolism are unknown.

Capillary Electrophoresis With Amperometric Detection for Neurotransmitter Analysis: Principles, Electrode Materials, Methodologies, and Applications

open access: yesELECTROPHORESIS, EarlyView.
This review provides a comprehensive summary of monoamine neurotransmitter analysis by capillary electrophoresis with amperometric detection. Fundamental principles of amperometric detection, electrode positioning strategies, and approaches to high‐voltage decoupling are described, followed by a critical comparison of electrode materials, selection of ...
