Electrochemical water splitting holds promise for producing clean hydrogen at industrial scales, but current technologies often falter under large current densities. Recent advances in catalyst design and scalable synthesis strategies are bridging this gap, offering materials that maintain high efficiency, stability, and durability under harsh operational conditions. This review synthesizes progress in scalable electrocatalyst production, from electrodeposition and corrosion engineering to thermal treatment approaches, and further to their combinations. By addressing the key challenges of performance degradation, bubble management, and cost limitations, the study highlights emerging solutions that can accelerate the industrial adoption of green hydrogen production technologies.

Organic cathodes have long been sought after for safe, sustainable, and recyclable energy storage, yet their development has been hampered by solubility, low voltage, and poor conductivity. In this study, researchers report a hexaazatriphenylene-based polymer with a three-dimensional (3D) framework that successfully addresses these challenges. The material exhibits remarkable insolubility, strong electronic delocalization, and accessible redox sites, resulting in a zinc–organic battery with an impressive initial discharge voltage of 1.32 V and an extraordinary lifespan of more than 40,000 cycles with over 93% capacity retention. This work provides a new molecular design strategy for creating high-voltage, ultrastable organic batteries.

This paper proposes an intermittent measurement-based attitude tracking control strategy for spacecraft operating in the presence ofsensor-actuator faults. A sampled-data (self-)learning observer is developed to estimate both the spacecraft’s states and lumped disturbances, effectively mitigating the impact of faults. This observer acts as a virtual predictor, reconstructing states and actuator fault deviations using only intermittent measurement data, addressing the limitations imposed by sensor failures. The control scheme incorporates compensation based on the predictor’s estimates, ensuring robust attitude tracking despite the presence of faults. We provide the first proof of bounded stability for this learning observer utilizing intermittent information, expanding its applicability. Numerical simulations demonstrate the effectiveness of this innovative strategy,  highlighting its potential for enhancing spacecraft autonomy and reliability in challenging operational scenarios.
