Summary: Researchers achieved uniform sodium deposition by using halloysite nanotubes as insulated scaffolds and introducing Ag nanoparticles as sodiophilic sites. The presence of Ag greatly increased the binding energy of sodium on HNTs/Ag. The coordination between HNTs and Ag contributed to high Coulombic efficiency, long lifespan, and remarkable cycle stability in Na metal full batteries.

Summary: A dickite with an expanded layer structure was prepared by co-calcination of the dickite-urea intercalation complex, urea, and potassium chlorate. The expansion degree of the dickite layer was regulated by the mass ratio (P/I) of potassium chlorate to the intercalation complex. XRD and SEM results showed that with the increase of the P/I ratio, the (002) diffraction intensity of expanded dickite gradually weakened and the degree of layer expansion gradually increased. When the P/I ratio exceeded 0.375, the expanded dickite exhibited an accordion-like porous morphology. The layer expansion of dickite increased its specific surface area, mesopore volume, and absolute zeta-potential, enhancing the adsorption capacity of methylene blue.

Summary: The application of nanotechnology in agrochemicals release can effectively reduce fertilizer usage and improve utilization. Urea was successfully intercalated into halloysite by solid-phase milling, and the maximum loading was 14.99 ± 1.33 wt%. Urea-Hal-sodium alginate hydrogel beads were fabricated by crosslinking, which showed good water retention and slow release properties. The release time of urea in the hydrogel was 60 times longer compared to pure urea. The hydrogel has a promising future in slow-release fertilizers for modern agriculture.

Summary: Nanocomposites based on alginate and halloysite were developed and characterized. The Hy/Alg nanocomposites exhibited negative charge density and good thermal stability. The adsorption capacity for Cd(II) decreased with increasing halloysite content in the nanocomposite. The Cd(II) adsorption equilibrium was affected by pH and temperature, with electrostatic interactions playing a role. The adsorption rate was enhanced by the presence of Hy in the nanocomposites.

Summary: Rapid global industrialization has exacerbated the contamination of heavy metals in aquatic ecosystems. In this study, green, ultrafine cellulose-based porous nanofibrous membranes were developed for efficient removal of heavy metals by incorporating chitosan and using electrospinning techniques. The conventional electrospinning method resulted in a more uniform distribution of chemically active sites, leading to improved adsorption performance and reduced surface shrinkage during adsorption. The 30% CS conventional nanofibrous membranes exhibited the highest adsorption capacity for copper ions at a solution pH of 5.

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.
