Summary: Aquatic pollution, including organic debris and heavy metals, poses a serious threat to living organisms. Copper pollution is harmful to humans, and there is a need for effective methods to remove it from the environment. A novel adsorbent, Fr-MMWCNTs-Fe3O4, was developed and characterized in this study. Batch adsorption tests showed that Fr-MMWCNTs-Fe3O4 had a maximum adsorption capacity of 250 mg/g at 308 K and could efficiently remove Cu2+ ions over a pH range of 6 to 8. The results demonstrate the potential of Fr-MMWCNTs-Fe3O4 composites as an efficient adsorbent for removing Cu2+ ions from untreated natural water sources.

Summary: The widespread use of fungicides is causing water pollution. This study focused on carbendazim, a model fungicide, and examined its adsorption on activated carbon (AC). The optimal conditions for carbendazim adsorption were determined to be an AC dosage of 0.3 g, reaction time of 150 min, and pH ranging from 3.0 to 10.0. The adsorption capacity reached 32.31 mg g(-1) under these conditions. The adsorption process was found to be a monolayer adsorption that occurred on the surface of the AC. The study also confirmed that the adsorption of carbendazim was an endothermic process with physical and chemical adsorption. The findings of this study can be applied to other types of AC and provide valuable information for treating fungicide wastewater.

Summary: This study investigated the removal of antibiotic ceftriaxone (CEF) from wastewater using mesoporous copper oxide nanosphere as an adsorbent. The adsorbent was characterized and found to have a surface area of 78.83 m2/g. The experiments showed that the adsorption of CEF was best achieved at pH 7 and the process was found to be endothermic, random, and spontaneous. Kinetic studies revealed that multiple mechanisms influenced the diffusion of CEF into the copper oxide, with the pseudo-second-order model providing the best fit. The Langmuir model was found to have the highest adsorption capacity, and the activation energy of the adsorption process was determined to be 14.43 kJ/mol.

Summary: The waste effluents of textiles and leather industries, which contain organic dyes as major contaminants, have been found to cause serious health problems. Adsorption techniques using mesoporous silica nanoparticles (MSNs) were investigated for the efficient removal of organic dyes from industrial wastewater. The MSNs were synthesized with selectively generated active inner/external surfaces by incorporating functional groups through co-condensation and post-grafting procedures. The study evaluated different grafting strategies and their effectiveness in removing cationic dye (methylene blue) from contaminated water samples. The results showed that nanomaterials containing sulfonic acid exhibited the highest adsorption performance, with an extraction efficiency of 98%. Increasing the salt concentration in the water samples improved the adsorption efficiency of all the nanomaterials.

Summary: This study investigates the transformation of iron-bearing precursors into jarosite-like minerals without the presence of bacteria or organic compounds. The composition of the solution determines the transformation, with crystallinity and long-term stability increasing as the temperature affects the kinetics of the process. Spectroscopic techniques were used to characterize the chemical species present on the mineral surfaces. Schwertmannite is the initial phase to precipitate, which transforms into a crystalline Na-rich member of the solid-solution family. The transformation involves dissolution-precipitation reactions within the nanoparticles of the secondary phase, with Fe3+ transferring from the solid to the solution. The crystal structure of jarosite-like minerals provides geochemical information about the aqueous solutions they were formed in. Temperature-transformation-time diagrams were established to define the reaction pathways.

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.
