Iron oxide nanoparticles (NPs) with a size of 3 and 10 nm were used to prepare porous hybrid magnetic nanocomposite materials via polymerization in highly concentrated water-in-oil (w/o) emulsions. The NPs were dispersed in a monomer mixture (styrene-divinylbenzene), which was then polymerized to obtain porous solid monoliths with embedded magnetic nanoparticles. The NPs were characterized using x-ray...
A series of new non-ionic amphiphiles based on bis-galactobenzimidazolones have been synthesized by grafting alkyl bis-benzimidazolone units as hydrophobic tails on hydroxypropyloxygalacto-pyranose moieties as hydrophilic heads. Their surface and self-aggregation properties in water were evaluated. The compounds show very low critical micellar concentrations (CMCs) that decrease with increasing chain...
