Summary: A dual mediator, trimethylphenylammonium iodide (Me3PhN+I-), has been introduced in aqueous Zn-S batteries to regulate the reaction paths of sulfur cathodes and enhance their electrochemical performance. Me3PhN+ functions as a dissolution mediator to generate soluble polysulfide intermediates during discharge, allowing a facile solid-liquid-solid path for sulfur. The I-/I3- redox mediator catalyzes the oxidation of ZnS to sulfur during charge, and Me3PhN+ reduces the solubility of I3-, preventing shuttling while retaining catalyst power.

Summary: Reported a new type of ZnSO4-based eutectic electrolytes that are both safe and cost-effective for advanced Zn-I-2 batteries. These electrolytes show high stability in various solvents of polyhydric alcohols due to the involvement of multiple -OH groups in Zn2+ solvation and interaction with water. The propylene glycol-based hydrated eutectic electrolyte exhibits significant advantages over Zn(CF3SO3)2/Zn(TFSI)2-based eutectic electrolytes in terms of non-flammability and low price, resulting in Zn-I-2 cells with high reversibility and 91.4% capacity remaining under 20 C.

Summary: A reversible heterogeneous electrode of Zn-nanocrystallites/polyvinyl-phosphonic acrylamide (Zn/PPAm) with fast electrochemical kinetics is designed to address the poor reversibility of Zn-metal anodes. The electrode utilizes phosphonic acid groups, hydrophobic carbon chains, and weak electron-donating amide groups to ensure structural reversibility, suppress side reactions, and promote Zn2+ transport. The heterostructure and Zn nanocrystallites further enhance electrochemical reactivity. The Zn/PPAm electrode exhibits excellent cycle reversibility and durability in symmetrical cells and fiber-shaped batteries.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
