Summary: The oil spill is a significant pollution source in marine environments, and the use of magnetite nanomaterials (MNMs) is a commonly applied technique for oil spill remediation. This study focuses on synthesizing and using new ionic liquids (ILs) to modify the surfaces of MNMs and enhance their performance in absorbing crude oil. The results show that the modified MNMs achieved high efficiency in crude oil uptake, even at low MNMs:crude oil ratios. The study also found that the contact time had an impact on the effectiveness of the MNMs, with longer contact times leading to higher crude oil uptake.

Summary: Green dispersants are made from renewable materials, non-volatile compounds, or naturally available solvents. This review discusses the effectiveness of different types of green dispersants, including protein isolates and hydrolysates, biosurfactants, vegetable-based oils, and green solvents. The challenges and opportunities associated with these dispersants are also explained. The effectiveness of these dispersants varies depending on oil type, dispersant hydrophilicity/hydrophobicity, and seawater conditions. However, their relatively low toxicity and desirable physico-chemical properties make them potentially eco-friendly and effective dispersants for future oil spill response.

Summary: This paper describes a synthetic approach to producing ultra-small (approximately 6 nm), monodisperse oleic acid-capped cobalt-doped magnetite (CoxFe(3-x)O(4)) nanoparticles using a modified co-precipitation method under mild conditions. XPS analysis revealed compositions of Co0.12Fe2.88O4, Co0.33Fe2.67O4, and Co0.58Fe2.42O4 for stoichiometric amounts of Co corresponding to x = 0.1, 0.3, and 0.5, respectively. The resulting CoxFe(3-x)O(4) nanoparticles showed higher saturation magnetization values than those reported for CoxFe3-xO(4) nanoparticles of similar size, monodispersity, and Co content prepared by other methods.
