Summary: In this work, a facile method of incorporating NiCo-layered double hydroxide (NiCo-LDH) into GO-dispersed CNTs (GO-CNTs) with interconnected configuration was presented, showing superior oxygen evolution performance. The optimized NiCo-LDH/GO-CNTs composite exhibited low overpotential, small Tafel slope, and robust stability in alkaline media, outperforming pure NiCo-LDH and commercial RuO2. The excellent oxygen evolution performance was attributed to the synergistic effect and intimate electron interaction between LDH and GO-CNTs, suggesting potential industrial applications in non-noble metal-based water electrolyzers.

Summary: This study investigates the microstructure, precipitation behavior, and mechanical properties of a multi-directional forged and age-treated Mg-8.9Gd-1.8Y-0.5Zr-0.2Ag (wt%) alloy. The as-aged alloy exhibits a mixed structure consisting of dislocation-induced chain-like distributed beta' phases, homogeneously distributed beta' phases, and precipitation free zones (PFZs). The alloy aged at 498 K shows the optimal combination properties of strength and ductility. However, decreasing the aging temperature to 473 K results in a significant decrease in ductility at the cost of increased strength.

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.
