  • Publication number: 20120234756
    Abstract: Disclosed is a method of controlling a real-time oxidation-reduction potential in a hot water system to inhibit corrosion in the hot water system. The method includes defining one or more operational protective zones in the hot water system. One or more of the operational protective zones includes an oxidation-reduction potential probe that is operable to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the measured real-time potential to the controller, which assesses and interprets the transmitted potential to determine whether it conforms to an oxidation-reduction potential setting. If the measured potential does not conform the oxidation-reduction potential setting, the controller is operable to feed or remove one or more active chemical species into or from the hot water system and further operable to change at least one system parameter.

    Abstract: Method for oil removal. The method includes adding a magnetizable material, with or without appropriately selected surfactants, of order micron (having no net magnetization) or nanometer size to magnetize the oil or water phase by either making a ferrofluid, magnetorheological fluid, a magnetic Pickering emulsion (oil in water or water in oil emulsion), or any other process to magnetize either oil or water phases. The magnetized fluid is separated from the non-magnetic phase using novel or existing magnetic separation techniques or by permanent magnets or electromagnets thereby separating oil and water phases. The magnetized particles are separated from the magnetized phase using novel or existing magnetic separation techniques to recover and reuse the particles. The two magnetic separation steps can be repeated to further increase recovery efficiency of the liquid phases and the magnetizable particles reused in this continuous process.

These cells often have virus-specific T-cell receptors, as well as other surface markers that distinguish them from their youthful counterparts, and are thought to play a major role in the decline of the immune system with age. Here we disclose the use of magnetic cell separation methods and apparatuses to remove senescent T-cells defined by the surface markers CD8+, KLRG1+ and CD8+, CD28?. We disclose how these markers are used to remove anergic T-cells from the blood of aged C57BL/6 mice, resulting in lasting rejuvenation of their immunological marker profile. Using antibodies with magnetic microparticles linked to their Fc domains, we first developed a method to use magnets to filter out the unwanted cells from the blood, and later constructed a device that does this automatically.

  • Patent number: 8187460
    Abstract: The present invention is related to devices for manipulating magnetic particles that are suspended in a fluid, possibly containing a biological entity of interest, the magnetic particles being able to bind the entity of interest, the fluid being contained in a reaction vessel constituted by a large upper compartment with a funnel shape, an elongate lower compartment with a substantially constant cross-section and a closed base. The devices are especially useful in methods for the extraction of nucleic acid to enable them for further processing.

  • Patent number: 8187886
    Abstract: The invention relates to methods of isolating white blood cells (WBCs) from a sample, e.g., whole blood, using magnetic particles that specifically bind to WBCs and a series of specific steps and conditions. The methods can include one or more of decreasing the viscosity of the sample prior to WBC isolation, agitating the sample at specified frequencies, and/or using a sample container arranged such that all of the sample is placed in close proximity (e.g., within 5, 2, 1, or 0.5 mm) to the source of the magnetic field. The new methods provide for isolation of WBC preparations with high yield, purity, and viability. The methods are designed for compatibility with automation protocols for rapid processing of multiple samples.

  • Publication number: 20120125858
    Abstract: In a method for separating magnetizable particles from a suspension, the suspension is passed through a cylinder-symmetrical separator wherein the substance streams are separated by at least one tubular separation screen. The separator separates the substance stream into a concentrate as well as a so-called tailing and the control of the separation rate of the concentrate and tailing is carried out solely by controlling the flow rate. To this end, at least one separation screen (11, 21) is displaceable in the separator (10, 20), so that a variable gap (15, 25) is formed.

  • Publication number: 20120097615
    Abstract: Disclosed are a method and apparatus for treating oil-containing particulates such as mill sludge comprising applying a treatment solution to a particulate feed stream to form a treated slurry, applying a mechanical disrupter to the treated slurry to reduce an average particulate size, applying a magnetic separator to the treated slurry to form a ferrous slurry, and applying a thermal separator to the ferrous slurry to extract a hydrocarbon portion and produce a ferrous product stream. This basic method and the associated apparatus may be modified in a number of ways including, for example, applying a sizing operation to the oil-containing particulates to remove larger particles from the particulate feed stream, condensing a volume of the hydrocarbon portion or using magnetic separators of varying strength to provide ferrous slurries of varying ferrous content.

  • Patent number: 8158008
    Abstract: An embodiment of the invention relates to a device for detecting an analyte in a sample. The device comprises a fluidic network and an integrated circuitry component. The fluidic network comprises a sample zone, a cleaning zone and a detection zone. The fluidic network contains a magnetic particle and/or a signal particle. A sample containing an analyte is introduced, and the analyte interacts with the magnetic particle and/or the signal particle through affinity agents. A microcoil array or a mechanically movable permanent magnet is functionally coupled to the fluidic network, which are activatable to generate a magnetic field within a portion of the fluidic network, and move the magnetic particle from the sample zone to the detection zone. A detection element is present which detects optical or electrical signals from the signal particle, thus indicating the presence of the analyte.

    Abstract: A method for magnetically assisted extraction of a target substance from an aqueous solution containing a plurality components includes mixing a surfactant and functional magnetic particles having affinity for the target substance into the aqueous solution containing the target substance so as to bind the target substance to the functional magnetic particles and form a particle-containing single-phase aqueous surfactant solution. The particle-containing single-phase aqueous surfactant solution is transitioned to a two-phase state, a first particle- and surfactant-containing disperse phase being formed within a surrounding second phase. The first particle- and surfactant-containing disperse phase and the surrounding second phase are separated using a magnetic field. The first particle- and surfactant-containing disperse phase are separated.
