Summary: The influence of structural modifications on the catalytic activity of carbon materials is investigated using carbonaceous materials with different pore networks and high nitrogen content. Results show that CO2 cycloaddition and Knoevenagel reaction are dependent on Lewis basic sites, while the absence of large conjugated carbon domains due to the introduction of nitrogen leads to poor redox activity. The material with the highest Lewis acid catalytic activity demonstrates the most effective small molecule activation and the highest concentration of electron-poor nitrogen species.

Summary: We developed a pH-sensitive growth mechanism to form in situ protective layers using glutaric acid (GA) and Zn2+ in the electrolyte solution. By deprotonating GA additives and integrating them with Zn2+ coordination, a thin Zn glutarate layer was formed to prevent hydrogen evolution reaction (HER) and Zn hydroxide sulfate hydrate (ZHS) precipitation. The study demonstrated the effective formation of Zn-organic protective layers for long-term cycling.

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.
