Summary: Hydrophobic mesoporous silica was developed through the surface grafting of the perfluoroalkyl group using fluorinated organosilane. The structure of the fluorinated MS remained unchanged, but the specific surface area and pore size decreased. With increasing fluorosilane content, the MS samples transitioned from hydrophilic to superhydrophobic surfaces. The fluorinated MS showed high separation efficiency and stability in oil-water mixtures and water-in-oil emulsions.

Summary: In this study, carbon particles were adsorbed on the surface of stainless steel meshes (SSMs) to form a thin hydrophobic coating, and a rough structure was then constructed through chemical vapor deposition and high temperature calcination, with the resultant SSM surface wrapped with uniform silica coating possessing superoleophobicity-underwater. The prepared SSMs exhibited superhydrophilicity in air and superoleophobicity-underwater. They showed high separation efficiency (above 98.8%) and separation flux (46,300 L·m(-2)·h(-1)) for oil/water mixtures. Immersion in different solutions did not significantly affect their separation efficiency (above 97.3%), and further immersion in dopamine and octadecylamine solutions transformed the SSMs into superhydrophobic SSMs with reverse surface wettability, which also exhibited good separation efficiency and separation flux for oil/water separation.

Summary: In this study, a superhydrophobic sponge (MS-EP-APT) was developed using asphaltene (APT), melamine sponges (MS) and polyethyleneimine (PEI) for demulsification and water-oil mixture separation. The sponge exhibited high separation efficiency for immiscible oil/water mixtures, surfactant stabilized water-in-oil (W/O) emulsions, and anionic surfactant-stabilized oil-in-water (O/W) emulsions. It also demonstrated good reusability and salt tolerance even in seawater, making it a promising candidate for green manufacturing and engineering in resource recovery and environmental remediation.

Summary: A novel superhydrophilic and underwater superoleophobic modified PVDF membrane was prepared through a modified blending method for oil/water separation. Pluronic F127 and amphiphilic copolymer P (MMA-AA) were blended directly with PVDF as a hydrophilic additive. The resultant membranes had contact angles of hexane larger than 150 degrees in both acidic and basic environments. The membrane surface changed from superoleophilic to superoleophobic under water with aqueous solutions with pH values from 2 to 13 for 1,2-dichloroethane droplets. The membrane exhibited good mechanical strength and could be used for oil and water mixture separation.

Summary: The development of technologies such as big data analytics, cloud services, IoT, personal mobile devices, social networks, and AI has created a strong demand for enterprises to accumulate information. The amount of recorded data is increasing by about 30-40% per year. Magnetic tape, hard disk drives, and solid-state drives are used for data storage. Hard disk drives are projected to control over half of the world's data due to their low cost per TB. This paper discusses new technologies to meet the growing density demands and competitive solid-state drives for data storage.

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.
