The Journal of Physiology, EarlyView.Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

Anion Mobility Renormalization Reveals Backbone‐Dependent Tortuosity in Anion Exchange Membranes
ChemElectroChem, Volume 13, Issue 11, 3 June 2026.Backbone polarity governs nanophase separation and tortuosity in anion exchange membranes (AEMs). The anion mobility across PPO‐ and PSU‐based ionomer membranes with quaternary ammonium groups depends exponentially on concentration. Extracted porosity–tortuosity ratios reveal lower tortuosity in PPO due to stronger PSU hydrophilicity.

ChemElectroChem, Volume 13, Issue 11, 3 June 2026.A gas‐phase electrolyzer with a Pt‐impregnated Nafion membrane anode was used for selectively oxidizing methanol to formaldehyde (FA) with low water content. However, maintaining the cell temperature at 100 °C for extended periods led to membrane dehydration and low water content in the effluent, causing most FA to react with methanol to form ...

Drive Cycle‐Based Accelerated Stress Tests for Heavy Duty Fuel Cell Vehicle Applications
Fuel Cells, Volume 26, Issue 3, June 2026.ABSTRACT Fuel cells in heavy‐duty vehicles are susceptible to degradation and are significantly influenced by driving patterns. Accelerated stress tests (ASTs) are useful to identify these degradation mechanisms and aid the development of degradation‐resistant control strategies for FC stacks.
