Summary: Mesoporous silica was successfully synthesized using geothermal water from the Onuma Geothermal Power Plant in Japan for the first time. Cetyltrimethylammonium bromide (CTAB) was used as an organic template for the synthesis, resulting in efficient recovery of supersaturated silicic acid from the geothermal water. The monosilicic acid in geothermal water plays a crucial role in the formation of mesoporous silica, which can contribute to preventing silica scale formation in geothermal power plant piping systems and serve as an industrial resource.

Summary: The adsorption of polymers on the surface of mesoporous silica nanoparticles allows for versatile adhesion between hydrogels or biological tissues. However, when the number of nanoparticles deposited exceeds a critical threshold, thick multilayers form at the interface and decrease the adhesion strength. To overcome this limitation, spherical aggregates were prepared by spray drying, resulting in stronger cohesion between nanoparticles. The adhesion energy with these supraballs was significantly enhanced compared to nanoparticles, and corrugated interfaces stabilized by supraballs contributed to the largest adhesion enhancement.

Summary: Silica nanoparticles (SNPs) have versatile synthetic methods and tunable physicochemical properties, making them promising for biomedical applications. In this study, hollow mesoporous SNPs (HMSNPs) with different layer compositions were fabricated, and their degradation profiles were characterized in simulated body fluid. The results showed that the composition and number of layers influenced degradation rates, with particles containing more disulfide bridges being more responsive to enzymatic degradation. These findings suggest the potential utility of layer-by-layer HMSNPs for controlled drug delivery.

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.
