Summary: The development of a superhydrophobic copper mesh for efficient oil/water separation was investigated in this study. A monolayer graphene/polydimethylsiloxane (PDMS) mixture was coated on the copper mesh to enhance its hydrophobic properties. By combining graphene with different ratios of PDMS, the effect on the contact angle of the fabricated meshes was examined. Irradiation with a Nd:YAG -1064 nm laser improved the hydrophobicity of the surface, with the best result achieved at a laser-to-sample distance of 1.5 mm above the laser focal point. The developed graphene@Cu mesh showed a contact angle of 155.6o +/- 0.3 and demonstrated high separation efficiencies of 92% for HD-40 engine oil and 95% for toluene.

Summary: SHSO membranes have shown high efficiency in selectively separating oil from oil-water mixtures, but their stability under acid and alkaline environments, as well as the adsorption of heavier components of crude oils, still require further research. Additionally, the fouling performance of SHSO membranes in water-derived fouling has not been well studied in oil-water separation applications.

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.
