Summary: The study demonstrates the use of silane coupling agents on CI/SiO2 particles for efficient separation of oil/water mixtures and emulsions. The particles exhibit superhydrophobic and superoleophilic properties, making them effective sorbents for different oils. Additionally, the particles show high separation efficiency for hexane/water emulsions. The reusability and chemical durability of the superhydrophobic samples further enhance their potential for use in harsh conditions.

Summary: This study evaluated a chemical agent-free approach using froth flotation and centrifugation to enhance the separation of oil and solid materials at normal temperatures. The effects of various factors were analyzed, and it was found that the oil recovery and the oil content of residue could be effectively reduced. Fine particles comprising secondary minerals were found to enter the oil phase, which could be further reduced by a centrifugal treatment. The aqueous phase from the flotation and centrifugation processes was found to be reusable.

Summary: A mixed-dimensional heterostructured oil-water separation membrane consisting of electrospun PDMS/PVDF nanofibers and a hydrophilic PANI microfiltration membrane support was developed. The membrane achieved efficient separation of surfactant-stabilized oil-in-water emulsion by capturing and coalescing small oil droplets while allowing water to pass through. The membrane demonstrated stable flux and high separation efficiency in long-term crossflow experiments. Such heterostructured membranes with tunable wettability have great potential for practical oil-water emulsion separation.

Summary: In this study, hedgehog-like micro/nanostructure nickel particles were successfully fabricated via a hydrothermal route and modified with octadecyltrichlorosilane (ODTS) to exhibit superhydrophobic/superoleophilic properties, making them suitable for oil/water separation. The dense narrow thorns of the nickel particles contribute to their high sorption capacity for various organic solvents and oils, and they also demonstrate good resistance. Moreover, the modified particles can be used for oil/water emulsion separation with high efficiency.

Summary: Engineering the surface chemistry allows precise control of interfacial interactions, which is crucial for fabricating superior antifouling coatings and separation membranes. In this study, a hydrophobic chain engineering strategy is presented to regulate the membrane surface at a molecular scale. By sequentially assembling hydrophilic phytic acid and hydrophobic perfluorocarboxylic acids on a graphene oxide membrane, an amphiphilic surface is formed. The surface energy is reduced by introducing perfluoroalkyl chains, while the surface hydration can be tuned by changing the hydrophobic chain length, optimizing both fouling-resistance and fouling-release properties synergistically.

Summary: The conversion of Fe(III) to Fe(II) in heterogeneous Fenton is inefficient, but introducing magnetic Fe3O4 during the synthesis of biogenic schwertmannite (Sch) can enhance the catalytic activity. Fe3O4-loaded Sch with organic carbon (Fe3O4/Sch/C) shows much higher degradation activity for fluoroquinolone antibiotics compared to other catalysts, mainly due to the more electrons provided by organic carbons promoting Fe(II) generation in heterogeneous Fenton.
