The Dynamic Response Index: Non-intrusive extraction of proton exchange membrane fuel cell aging signatures from 1-Hz transients

Voltage loss is widely used to monitor proton exchange membrane fuel cell (PEMFC) aging, but it provides limited information during load-varying operation by combining irreversible degradation with reversible hydration, thermal, and recovery effects. To address this non-intrusive...

Spatial prediction of groundwater nitrate through machine learning and stakeholder co-creation: the Chalk aquifer case in East Anglia, UK

Nitrate contamination in groundwater threatens drinking water supplies worldwide. Data-driven methods can improve prediction and spatial mapping by transforming point observations into continuous regional information, supporting a better understanding of contamination patterns an...

Briefing: International research into surface and internal erosion of dams and levees

The need for a clearer understanding of how both surface and internal erosion processes develop across dams and levees has been at the forefront of research priorities for the last decade. Two events in 2025 gave the opportunity for researchers and practitioners to share details...
