Summary: Freestanding nanocomposite membranes composed of cross-linked chitosan and magnetically active NiO-Co3O4 spinel oxide filler were successfully synthesized through the solution-casting technique. The externally applied magnetic field allowed for better alignment of the filler and enhanced intermolecular interactions between the biopolymer and filler, leading to improved physicochemical properties. Increasing the SO doping concentration resulted in substantial enhancements in various properties, such as water uptake, ion-exchange capacity, water retention, and high-temperature proton conduction, making these membranes promising for use in high-temperature proton exchange membrane fuel cells.

Summary: Polyelectrolyte membranes (PEMs) containing chitosan and Nafion were prepared for DMFC application. The addition of Nafion increased the Tg and decreased the crystallinity of the chitosan matrix due to the interaction between -SO3H groups in Nafion and -NH2 groups in chitosan. The PEMs with higher Nafion loading weight exhibited higher proton conductivity and methanol permeability, and the membrane with 25 wt% Nafion showed comparable selectivity parameter to neat Nafion. A maximum power density of 39 mW cm(-2) was achieved for this membrane in DMFC performance test.

Summary: The study synthesizes sharp-edged pencil-type ZnO flowers and BiOI flakes using a hydrothermal process, and combines them with carbon nanofibers (CNFs) to form a hetero hybrid catalyst (ZnO-BiOI@CNFs). The hybrid catalyst exhibits significantly enhanced degradation of azo dyes under solar simulator exposure compared to pristine ZnO and BiOI nanostructures. The degradation rate of the hybrid catalyst reaches 95%, which is 1.8 times higher than ZnO and 2.1 times higher than BiOI nanostructures. The hybrid catalyst also demonstrates efficient degradation of mixed dyes, providing valuable insights for commercialization and industrialization. The superior performance is attributed to the unique structure of ZnO, larger absorption zone, high surface area, reactive sites, and reduced recombination rate with a heterojunction interface, as well as the electron trap and sink capability of CNFs.

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.
