Batteries &Supercaps, EarlyView.Anthraquinone‐disulfonate coordination polymers (AQDS‐Na, AQDS‐Mg, AQDS‐Cu) are synthesized and evaluated as cathodes for Li‐ion and Na‐ion storage. Structural dimensionality and coordinated water critically impact the practical capacity and cycling stability, highlighting design principles for organic‐based energy storage materials.

Nickel‐Doped h‐MoO3 Cathodes: A High‐Performance Material for Aluminum‐Ion Batteries
Battery Energy, EarlyView.Nickel‐doped hexagonal molybdenum trioxide (h‐MoO₃) shows a promising improvement in the capacity and stability of aluminum‐ion batteries. This work utilizes a simple precipitation method to incorporate nickel into h‐MoO₃, combined with a urea‐based electrolyte, achieving higher discharge capacities and extended cycling stability.

A General Approach to Dropout in Quantum Neural Networks
Advanced Quantum Technologies, EarlyView., 2023 Randomly dropping artificial neurons and all their connections in the training phase reduces overfitting issues in classical neural networks, thus improving performances on previously unseen data. The authors introduce different dropout strategies applied to quantum neural networks, learning models based on parametrized quantum circuits.
