Summary: Highly ordered hexagonal mesoporous silica was synthesized from natural Opoka minerals, and an all-atom model of MCM-41 was constructed by simulation. Characterization techniques such as XRD, N2 adsorption, FE-SEM, TEM and FT-IR were used, and the water vapor adsorption/desorption performance of the samples was evaluated. The simulation revealed that water molecules on MCM-41 mainly adsorbed on silanol groups and skeleton defects, and the adsorption changed from mono-layer to multi-layer with increasing pressure.

Summary: This paper investigates the adsorption performance of silver-modified mesoporous materials in removing thiophenic compounds. The results show that the adsorption of thiophene by the sorbents involves S-Ag and pi complexation reactions, and the adsorption efficiency is greatly affected by benzene. XPS analysis reveals that silver interacts strongly with the carrier and forms Ag-O-Si bonds as the active centers for thiophenic compounds. The Mulliken charges of sulfur atoms have an impact on the interactions between silver and thiophene sulfur compounds.

Summary: The contamination of antibiotics in the environment has become a serious concern. The development of cost-effective and environmentally friendly adsorbent materials is crucial in addressing this issue. Mesoporous molecular sieve MCM-41 shows significant promise due to its strong adsorption capacity, low cost, and efficient regenerative properties. This study investigated the adsorption behavior of demolded MCM-41 materials for tetracycline, doxycycline, and levofloxacin at different temperatures and pH levels. The results showed that a neutral or weakly acidic pH environment promoted adsorption, while alkaline conditions hindered it. The maximum adsorption capacities were determined for each antibiotic, highlighting the potential of MCM-41 in mitigating antibiotic wastewater contamination.

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.
