摘要:
The invention relates to a novel magnetic liquid and to a method and device for the production thereof. The aim of the invention is to produce a magnetic liquid which is based on a polar carrier liquid having a high saturation magnetization, i.e. having a high concentration of nanometer particles and a low viscosity, and to provide a method and device for the production thereof. To this end, a magnetic liquid is provided which comprises a saturation magnetization of at least 30 mT and a viscosity under 100 mPas at 40 DEG C, whereby the carrier liquid contains essentially no dissolved components of the outer adsorption layer.

A liquid desalination system is disclosed. The liquid desalination system includes a feed line having an inlet to receive liquid and an outlet to discharge the liquid. The liquid desalination system includes a magnet coupled to the feed line, the magnet to generate an oscillating magnetic field within the feed line and in opposition to the feed water flow. The removal of targeted ions can be achieved by manipulating the frequency and rate of the generated electromagnetic waves. The generated electromagnetic waves can be tuned to weaken the hydration bonds of that specific ion and facilitate its removal. The liquid desalination system generates an electric field across the feed line to enable the liquid to flow through the electric field. The electric field may attract sodium ions to a positive electrode and may attract chloride ions to a negative electrode, to desalinate the liquid in the feed line.

A system and method for magnetic density separation of products (1a, 1b). The system (10) comprises a magnet (2) configured to amplify a density gradient (D) in a magnetic liquid (L) for separating the products (1a, 1b) in the magnetic liquid (L) according to their different density (Da, Db). A plate shape (3) is disposed along a product path (P) where respective products (1b') travel through the magnetic liquid (L). A driving mechanism (4) is configured to drive the plate shape (3) with a reciprocating motion (R) for lowering a static friction of the respective products (1b") coming into contact with the plate shape (3). Accordingly, process continuity can be improved while maintaining a high separation efficiency, in particular by alleviating material build-up and clogging of products at the splitter and other surfaces with minimal disturbance to the process flow.

Devices, methods, and systems are provided for extracting particles from a ferrofluid and for rapid affinity measurements. Such systems may comprise a fluidic channel or chamber configured to include a ferrofluid having a plurality of target particles and background particles. The systems may include a capture region configured to capture at least a portion of the plurality of target particles. In addition, the systems include a first magnetic field generator and a second magnetic field generator. The first magnetic field generator may be arranged proximate to the fluidic channel, the first magnetic field generator being configured to generate a first magnetic field configured to direct the plurality of target particles towards the capture region. The second magnetic field generator can be arranged to be proximate to the capture region, and is further configured to generate an affinity thresholding magnetic field configured to remove background particles from the capture region.
摘要:
A medical device and method for detection, retrieval or elimination of disease- associated toxins and biomarkers is provided. A plurality of magnets is arranged within a flexible sheath forming a flexible wire. The magnets are magnetically attached to each other, end-to-end, and arranged with their magnetic polarities alternating in direction. The magnetization direction of each of the magnets is orthogonal to the length axis of the flexible wire. The medical device is completely self-contained and does not require a bulky external field source able to maintain strong magnetic field gradients (100- 10,000 T/m) along the wire, and at a radial distance (~1 mm) to attract magnetic particles throughout the entire vein diameter at a range of physiologic velocities (1-10 cm/sec). This technology is a major step forward for the clinical relevance of CTC analysis to personalized medicine and introduces a powerful generalizable strategy for enrichment of other rare blood biomarkers.
摘要:
The invention relates to a novel device and process for enriching magnetic minerals (magnetite) by removing metal sulphides, silicates, phosphates and other unwanted particles, characterised by a device comprising a downflow pipe (mixer) and a separation column surrounded by Helmholtz coils. Pulp is fed into the mixer, in which air bubbles form in the presence of the pulp and bubble-particle collection processes are performed. The mixer discharges the pulp-bubble mixture into the separation column in a region that has a low magnetic field, less than 200 Gauss, which can be adjusted. Non-magnetic particles (gangue) are removed by the bubbles at the upper part of the column to form the tailings from the process, while magnetic particles sediment rapidly on the bottom of the column, from where they are removed to form the iron concentrate. As a result of the increase in the percentage of solids in the concentrate cone, most of the water that enters the device is discharged in the tailings, generating an upward flow of water which drags the gangue particles that were not captured by the bubbles. Using these mechanisms, the gangue is discharged in the tailings by two methods: flotation, and hydrodynamic drag. The magnetite forms aggregates of sufficient weight that they are not conveyed by the bubbles but sediment rapidly on the bottom of the column, allowing selective separation of magnetite and gangue.
