Summary: The use of alternative and water-soluble polymer binders, such as PVA and PAA, can improve the cycling performance of Si-based Li-ion batteries by modifying the hydroxyl groups of PVA chains. Among the binder systems investigated, PVA with the highest degree of hydrolysis demonstrated superior performance and better capacity retention compared to modified PVAs and PAA as a binder for Si anodes. The effects can be attributed to the crystallinity of the binder system, which improves electrode integrity during cycling and reduces swelling of the Si particles.

Summary: Flexible zinc-ion batteries (ZIBs) with high safety and low production cost are ideal power sources for portable devices. The low mass-loading and limited areal capacity of the cathode materials are the main challenges for practical ZIBs. This study introduces a binder-free flexible vanadium oxide (MCV@CC) cathode with high mass-loading and large areal capacity, achieved through the bridge effect of MXene. The binder-free cathode reduces the electrochemically inactive weight and enhances the energy density of ZIBs. The MCV@CC cathode demonstrates desirable areal capacity and cycling stability, and the reaction mechanism is found to be based on reversible Zn2+/H+ (de)intercalation in the vanadium oxide interlayer. The use of the bridge effect strategy in constructing high mass-loading flexible electrodes provides insights for ZIBs applications.

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.
