  • Publication number: 20100099941
    Abstract: Magnetic nanoparticle compositions are provided which provide an inherent temperature regulator for use in magnetic heating, particularly for use in magnetic hyperthermia medical treatments. The composition includes magnetic nanoparticles having a Curie temperature of between 40 and 46° C., preferably about 42° C., and may further include a polymeric material and optionally a drug or radiosensitizing agent. Methods of hyperthermia treatment of a patient in need thereof are provided which include administering to the patient a composition comprising magnetic nanoparticles having a Curie temperature of between 40 and 46° C.; and exposing the magnetic nanoparticles in the patient to an alternating magnetic field effective to generate hysteresis heat in the nanoparticles.

  • Publication number: 20090301272
    Abstract: A cable pliers structure includes a left plier body and a right plier body pivotally connected to each other. The right plier body has an adjusting region. The left plier body is connected with a drive seat movably disposed on one side of the adjusting region. A pressing block is disposed at the top of the drive seat. A clamping component is disposed in the adjusting region and has a clamp base that is movable relative to the pressing block. When the relative distance between the clamp base and the pressing block is changed, that is, the clamp base moves away from or approaches the pressing block, the distance is equivalent to the specification and dimension of a cable connector to be used. Therefore, the cable pliers structure is suitable for cable connectors of various specifications and dimensions through adjusting the distance, without replacing the pressing block.

  • Patent number: 6989196
    Abstract: Microencapsulation methods and products are provided. The method includes forming, at a first temperature, a emulsion which comprises aqueous microdroplets, including the agent (e.g., a magnetic material or drug) and a cross-linkable matrix material (e.g., a protein such as albumin), dispersed in a hydrophobic continuous phase comprising an oil and an oil-soluble surfactant, the first temperature being below the temperature effective to initiate cross-linking of the matrix material, and then heating the emulsion to a temperature and for a time effective to cause the matrix material to self-crosslink, to form microparticles comprising the agent encapsulated by the crosslinked matrix material.

  • Publication number: 20050239948
    Abstract: Methods are provided for aligning carbon nanotubes and for making a composite material comprising aligned carbon nanotubes. The method for aligning carbon nanotubes comprises adsorbing magnetic nanoparticles to carbon nanotubes dispersed in a fluid medium to form a magnetic particle-carbon nanotube composite in the fluid medium; and exposing the composite to a magnetic field effective to align the nanotubes in the fluid medium. The method for making a composite material comprising aligned carbon nanotubes comprises (1) adsorbing magnetic nanoparticles to carbon nanotubes to form a magnetic particle-carbon nanotube composite; (2) dispersing the magnetic particle-carbon nanotube composite in a fluid matrix material to form a mixture; (3) exposing the mixture to a magnetic field effective to align the nanotubes in the mixture; and (4) solidifying the fluid matrix material to form a nanotube/matrix material composite comprising the aligned nanotubes which remain aligned in the absence of said magnetic field.

  • Publication number: 20040126254
    Abstract: A micropump formed from a monolithic body and rotatable disc contained within the body. The rotatable disc may include one or more prostrusions for drawing a fluid through an inlet and expelling it through an outlet. The protrusions may be formed in a spiral formation, extend as radial vanes from a central point, or have another configuration. The micropump may have a thickness no more than about 12 microns. In other embodiments, the rotatable disk includes one or more gears that utilize positive displacement to pump fluids. The micrompump may be used with other microelectromechanical systems and devices.
