Summary: In this study, a detailed comparison was made between conventional supercritical drying and evaporative drying for hierarchically organized porous silica gel monoliths. The effect of the two drying procedures on the pore properties and monolith shrinkage was evaluated through comprehensive characterization. It was found that evaporative drying can compete with supercritical drying in terms of material and textural properties for hierarchically organized porous solids, and the pore properties can be tailored by adjusting the drying conditions.

Summary: The construction of MOF monoliths can overcome the limitations of MOF powders, such as pressure drop, mass transfer inefficiency, and operational complexities. However, challenges still exist in terms of pore clogging, pore structure tuning, and mechanical properties. In this study, nearly pure ZIF-8 monoliths with hierarchical pore structure were successfully prepared by converting amorphous ZIF-8/ZnO nanoparticles into continuous ZIF-8 skeleton. These monoliths exhibited low bulk densities, high BET surface areas, and good mechanical properties. They also demonstrated high catalytic activity and stability in a continuous flow reactor for the Knoevenagel reaction. This work presents a valuable approach for the application of MOF-based monoliths in adsorption, separation, catalysis, and effluent treatment.

Summary: This study investigated the production of porous epoxy micro-beads using a single epoxy droplet in heated corn oil, showing that a higher ammonium bicarbonate content led to increased decomposition rate and gas volume, resulting in micro-beads with smaller particle size, lower specific gravity, and better thermal stability. Furthermore, porous epoxy micro-beads with open pores exhibited low specific gravity and high thermal stability at high ammonium bicarbonate content, with particle size and shape dependent on the content of ammonium bicarbonate and the ratio of epoxy to polyamide used.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
