摘要： 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%.

摘要： A system for sorting metallic objects by magnetic separation has an electromagnetic core. The electronic core includes at least a first portion, a second portion, and a bottom. A sorting flap is arranged facing the electromagnetic core to fashion a circulation space for a conveyor of objects to be sorted from the first portion toward the second portion. The sorting flap includes a magnetic element arranged to form an air gap (E1) between the first portion and the sorting flap. The air gap forms a magnetic barrier opposing the passage of non-magnetic metallic objects, such that the objects are ejected from the conveyor. The second portion is arranged to ensure a return of the magnetic flux lines toward the first portion.

摘要： A method is described for controlling an oil spill by seeding micron-sized magnetizable particles in the oil. Once seeded, particles can form a unique and preferential bond with the oil resulting in creation of a colloidal mixture. This bond forms as a result of a combination of forces including the intermolecular Van der Waal forces. Once this bond is formed, the oil is rendered magnetic and can be controlled and moved in response to a magnetic field. This can include removing oil from water, reducing the diffusion rate of oil on water, magnetically lifting oil from water or nonporous surfaces, as well as separating the magnetic material from the oil.

摘要： Devices for separating magnetically labeled moieties in a sample are provided. Aspects of the devices include a magnetic field source, a first magnetic field guide having a wedge-shaped portion with an apex edge, and a second magnetic field guide having a wedge-shaped portion with an apex edge. The apex edge of the first magnetic field guide is aligned substantially across from and parallel to the apex edge of the second magnetic field guide, and the device is configured to separate magnetically labeled moieties from non-magnetically labeled moieties in the sample. Also provided are methods of using the devices, as well as systems and kits configured for use with the devices and methods.

摘要： A splitter that physically delineates the travel path between material steams having different trajectories mounted on a metal sorting system. The splitter has an outer edge and comprising an automatic mechanism located at the outer edge for removing accumulated debris from the splitter. The automatic mechanism may be a sliding body that moves across said outer edge or a retractable blade extends and retracts to remove debris from the splitter.

摘要： A microfluidic separation system, which comprises a magnetic separator, which itself comprises a magnetic energy source; first and second magnetically conductive members leading from the magnetic energy source and having respective terminal ends that are separated by a gap over which a magnetic field is applied due to the magnetic energy source. The separation system further comprises a microfluidic chip for insertion into the gap, which comprises a body defining channels on respective faces of the body; and an exterior lining that seals the plurality of channels to allow separate test sample volumes to circulate in at least two of the channels. Upon insertion of the chip into the gap, a first test sample volume is confined to circulating closer to the terminal end of the first member and a second test sample volume is confined to circulating closer to the terminal end of the second member.

摘要： A method, system, apparatus, and article of manufacture provide a cross-flow migration classifier capable of separating particles. The classifier provides a channel through which a sample, having one or more particles, passes in a first direction, wherein the channel comprises two or more walls that are permeable to a flow of fluid. A cross-flow enters the channel through one of the permeable walls and exits through another of the permeable walls. An imposed field is applied in a second direction that is counter to the cross-flow and having an orthogonal component to the first direction. The imposed field causes one or more of the particles to migrate at a first velocity opposite and/or equal to a second velocity of the cross-flow. The particles that migrate opposite to the cross-flow are continuously discharged from the cross-flow migration classifier.
