Summary: Natural montmorillonite is modified with cetyltrimethylammonium bromide (CTAB) to obtain an organoclay, which is used as an adsorbent for the removal of orange G anionic dye from aqueous solutions. The adsorption process follows a pseudo-second-order kinetic model and a Langmuir model, with a maximum adsorption capacity of 167 mg g(-1) at 298 K. Molecular dynamics simulations provide insight into the structural properties of the CTAB intercalated into montmorillonite and the adsorptive characteristics of orange G dye on CTAB@Mt.

Summary: This study reported the experimental and theoretical studies on the adsorption of Cu(II) on Na-montmorillonite surface. The adsorption reached equilibrium within 80 min with an adsorption capacity of 35.230 mg middot g(-1) at 25 degrees C. The adsorption data of Cu(II) followed pseudo-second-order kinetic and Langmuir isotherm models. The simulation results showed no significant differences in the adsorption energy of Cu(II) at different sites on the montmorillonite surface, and Cu(II) had more electron transfer than Na(I).

Summary: The removal effect of montmorillonite (Mt) on antibiotics, specifically ciprofloxacin (CIP) and erythromycin (ERY), was investigated in this study. Adsorption kinetics and isotherm experiments confirmed the effectiveness of the generalized Langmuir model in describing the adsorption process, with higher adsorption capacity observed for CIP. The intercalation and adsorption behaviors of CIP and ERY on Mt surface were analyzed using various techniques, revealing the competitive adsorption mechanism of these antibiotics. Moreover, the adsorption of antibiotics on Mt under different pH conditions was studied, and the competitive adsorption results were supported by the potential energy distribution.

Summary: The adsorption-hydration hybrid method in ZIF-8 for CH4 storage involves bidirectional migration between hydrate growth and physisorption, increasing CH4 adsorption capacity. The competition for CH4 adsorption between ZIF-8 and hydrate surfaces affects the stability of intergranular CH4 hydrates. Intergranular hydrates can exist stably and grow continuously after reaching maximum adsorption capacity, with partially adsorbed CH4 molecules promoting hydrate growth through outward migration.

Summary: The present study synthesized two new materials, MWCNT-OH-Mag and MWCNT-COOH-Mag, by functionalizing multi-walled carbon nanotubes (MWCNT) with magnetite (Fe3O4) using solution precipitation methodology. These materials were characterized using various techniques and showed effective impregnation and regular distribution of nanoparticles on the surface. Batch studies indicated that MWCNT-OH-Mag exhibited superior adsorption performance for 2,4-D and Atrazine pollutants, with optimal pH conditions of 2 and 6, respectively. The adsorption kinetics reached equilibrium within 30 minutes, and the Sips model accurately described the adsorption isotherms. The synthesized materials demonstrated high stability in aqueous solutions and showed promising potential for water purification through adsorptive separation.

Summary: This study examines the interaction between montmorillonite and polyacrylamide (PAM) with different ionic types using QCM-D and MD simulations. The study found that pH decrease led to increased montmorillonite adsorption on the alumina surface. CPAM had the strongest adsorption mass, followed by NPAM, and APAM had the lowest adsorption. CPAM also had the strongest bridging effect, while APAM had a negligible effect. MD simulations showed that the ionicity had a significant influence on the adsorption of polyacrylamides, with the cationic functional group having the strongest attraction.

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.
