  • Publication number: 20230338586
    Abstract: Contrast agents, compositions including contrast agents, methods of forming contrast agents, and methods of imaging. Contrast agents may have a desirable solubility in liquids, such as aqueous liquids. Methods of forming contrast agents may include contacting a polymer that includes anhydride functional groups with one or more compounds. Methods of imaging may include administering to patients a contrast agent or composition including a contrast agent.

  • Patent number: 8071162
    Abstract: Known techniques for forming nanoparticles require a multiple-step process to coat a surface with nanoparticles. The present invention provides a single-step process that requires the deposition of a substrate in a mixture of a solvent, ligands and organometallic precursors. The mixture containing the substrate is heated under pressure in a dihydrogen environment for a predetermined period of time, during which supercrystals of nanoparticles form on the substrate.
    Type: Grant

  • Patent number: 7429339
    Abstract: A magnetic nanoparticle (22), a magnetic nanomaterial (30), assembly (30), and a method for synthsising a magnetic nanoparticle, relating to thermodynamically stable and air stable ferromagnetic nanoparticles of adjustable aspect ratio made upon decomposition of organometallic precursors in solution in the presence of a reaction gas and a mixture of organic ligands. The magnetic nanomaterial comprises magnetic nanoparticles of homogeneous size, shape, and magnetic orientation that comprises a magnetic core (24, 34) ferromagnetic at room temperature and/or operating temperatures, and a non-magnetic matrix (26, 36) encapsulating the magnetic core. This magnetic nanomaterial could be used in high frequency integrated circuit applications, such as used in wireless portable electronic devices, to enchance magnetic field confinement and improve passive component performance at MHz and GHz frequency in a variety of passive and active devices, such as transformers, on-chip signal isolation, inductors, and the like.

  • Publication number: 20070298520
    Abstract: A method of producing an electrical inductor circuit element comprising an elongate electrical conductor encircled by magnetic material extending along at least a part of the conductor. First and second sacrificial layers are formed across the conductor respectively above and below the conductor, at least parts of the sacrificial layers are removed to leave a space encircling the conductor, a fluid comprising magnetic nanoparticles dispersed in a liquid dispersant is introduced into the space, and the dispersant is removed leaving the magnetic nanoparticles densely packed in the space as at least part of the magnetic material.
