Abstract: Coated magnetic nanoparticles and methods for attracting, isolating, and/or removing of particulate waste from environments are provided. A coated magnetic nanoparticle may include an iron-containing core surrounded by a hydrophobic or amphiphilic coating. This coating can include a functional group based on PDMS such as C-PDMS, PDMS-co-APMS, and/or PDMS-OH block copolymers. The magnetic nanoparticles may be synthesized in air or air-free in an inert gas. The magnetic nanoparticles may be introduced into, for example, an aqueous environment to bind with waste contained therein through an adsorption process. The magnetic nanoparticles and bound waste may be attracted and removed from the environment by introducing an external magnetic field.

Abstract: A core-shell nanocomposite is formed by co-assembly of an amphiphilic polymer and hydrophobically modified magnetic nanoparticles, with its core being a hydrophobically modified magnetic nanomaterial and its shell being the amphiphilic polymer, wherein hydrophilic segments in the amphiphilic polymer are located at an outermost layer of the shell. The above composite can be used as additives in the crystallization of conglomerates and obtain optically pure crystals of both enantiomers in a single process. The key thereof is that the composite is used to enrich molecules with the same configuration while inhibit the crystallization of the other enantiomer in a supersaturated solution of conglomerates, such that a non-magnetic crystal and a magnetic crystal (which are enantiomers of each other) are generated in a unit operation. Optically pure crystals of both enantiomers with over 90 ee % can be obtained by one-time crystallization, and the total yield can be as high as 40%.

Abstract: The object of the invention is an apparatus (50) for magnetic treatment of fluids, comprising a substantially cylindrical housing (6), having a bottom wall (61), a top wall (62), and a sidewall (60) running around the circumference of the bottom wall (61) and of the top wall (62) of the housing; at least one inlet opening (2, 3) and at least one outlet opening (4) formed in a wall of the housing (6); at least one magnet (8) connected to the housing (6), wherein the magnetic field of the magnet intrudes into the housing; wherein one or more inlet tubes (30) are connected to the one or more inlet openings (2, 3), wherein the inlet tubes are at least partially tangential at least in the proximity of the inlet opening. As a result of this configuration, the velocity vector of the fluid to be treated has a significant tangential component during most of its travel through the apparatus and thus the fluid crosses the magnetic field lines of the magnets having their magnetic axes oriented parallel with the centerline of the housing such that the angle formed between said field lines and said velocity vector is large.
