Summary: Rechargeable aqueous hybrid Zn batteries (HZBs) have gained attention for their low-cost, safety, and eco-friendly features. However, the lack of high-performance and stable cathode materials has hindered large-scale practical applications. In this study, Co1.29Ni1.71O4 nanowires (NWs) grown on nickel foam were found to exhibit reversible redox response and high catalytic activity for oxygen reduction/evolution reactions, thanks to their freestanding nanowire array structure. The HZB assembled with these NWs showed excellent cycling stability, achieving 6680 cycles over 2127 hours with a discharge capacity of 168.3 mA h g(-1) in KOH electrolyte. The HZB also demonstrated a flat discharge voltage plateau of -1.65 V, nearly 100% Coulombic efficiency, and remarkable rate performance. This work provides a promising approach to design and synthesize cathode materials for rechargeable aqueous HZBs.

Summary: The problems of zinc anode, such as dendrite growth and hydrogen evolution, significantly impair the performance of zinc batteries. The solid electrolyte interphase (SEI), crucial for achieving high reversibility of lithium anode in non-aqueous organic solvents, also contributes to the improvement of zinc anode performance in aqueous electrolytes. However, current research on the interphase for zinc electrodes is fragmented, lacking a deep understanding of the underlying causes or general design rules for SEI construction. The high reactivity of water molecules poses a serious challenge for effective SEI formation.

Summary: In this study, a Co-doped dMO composite with reduced graphene oxide (GC-dMO) is developed using a simple cost-effective hydrothermal method. The GC-dMO cathode exhibits an excellent capacity of 302 mAh g(-1) at a current density of 100 mA g(-1) after 100 cycles as compared with the dMO cathode (159 mAh g(-1)). The excellent electrochemical performance of the GC-dMO cathode owing to Co-doping and graphene oxide sheets enhances the interlayer gap and disorderness, and maintains structural stability, which facilitates the easy reverse intercalation and de-intercalation of Zn2+ ions and H2O molecules.

Summary: Developing robust and highly active bifunctional electrocatalysts for overall water splitting is critical for efficient sustainable energy conversion. Here, heteroatom-doped amorphous/crystalline ruthenium oxide-based hollow nanocages are reported, which show excellent catalytic activity for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Specifically, Co-ZnRuOx nanocages deliver ultralow overpotential and small Tafel slope for HER, surpassing the performance of commercial Pt/C catalyst, and prevent Ru from over-oxidation under OER operation.

Summary: This study reports rechargeable aqueous batteries based on ammonium-ions, which have great potential in low-cost energy storage systems due to their superior characteristics. However, the development is challenged by the lack of cathode materials that can meet the requirements for high capacity and stable working voltage simultaneously. The researchers discovered NH4+ storage behavior in a MnAl layered double hydroxide (LDH) series and observed stable working voltage and high discharge capacity in an optimized LDH sample. Assembling the complete battery with a 3,4,9,10-perylenetetracarboxylic diimide anode resulted in a high energy density, outperforming most recently reported counterparts. The study also revealed the rapid amorphization conversion of the LDH cathode during the first charge process, which facilitates NH4+ isotropic transport and provides new insights into electrode design for aqueous batteries.

Summary: The study on stability criterion and interaction analysis for grid-connected inverters under weak grid conditions is highly valuable. This paper proposes a control loop stability criterion based on controller bandwidth overlap, which allows for independent analysis of each loop as well as overall system stability. By analyzing the interaction among the grid impedance, phase-locked loop, and current controller, the proposed criterion provides a deeper understanding of system stability under weak grid conditions. Simulation and experimental results validate the accuracy of the proposed stability criterion and interaction analysis.

Summary: In this study, we developed a method to prepare porous polymer particles with controllable surface textures. By combining emulsion interfacial instabilities and phase separation, we dissolved the oil phase of the emulsion containing the polymer, a cosurfactant, and a nonvolatile oil into a volatile good solvent. The evaporation of the good solvent triggered interfacial instability and phase separation, resulting in the formation of porous polymer particles with surface roughness. Varying the concentrations of the cosurfactant and nonsolvent allowed for the tuning of surface textures and internal pore structures. Porous polymer particles with surface roughness have potential applications in enzyme carriers, isolation and purification, superhydrophobic coatings, drug delivery, etc.

Summary: The sparsity of user-item interaction data limits the performance of recommender systems. To address this, researchers propose a meta-relation-assisted knowledge-aware coupled graph neural network (MKCGN) that combines user/item auxiliary information, optimizes spatially distributed properties, and improves representation quality. MKCGN shows average performance improvements of 5.26% and 4.87% on two real-world datasets compared to the state-of-the-art model.

Summary: Session-based recommendation uses click history to recommend the next click. Although GNN-based models show promising results, there are still limitations: ignoring item order, limited capturing of long-term dependencies, and interference from noise items in the session embedding. To address these issues, we propose MPER, which introduces learnable position embedding, SLD-encoder, adaptive sparse target attention, and a linear integration layer. Experimental results on three datasets demonstrate the superiority of MPER over SOTA baselines.

Summary: In this study, a novel composite of bacterial cellulose (BC) and expanded vermiculite (EVMT) was used as an adsorbent for dyes and antibiotics removal. The BC/EVMT composite exhibited a microporous structure, providing abundant adsorption sites. The adsorption capacity of BC/EVMT for methylene blue (MB) increased with increasing pH, while the adsorption capacity for sulfanilamide (SA) decreased. The Langmuir isotherm model and pseudo-second-order kinetic model were found to fit the adsorption of MB and SA well on the BC/EVMT composite. The BC/EVMT composite showed high adsorption capacities for both MB and SA, making it a promising adsorbent for wastewater treatment.
