  • Polar monomer grafted polypropylene resin, preparation method therefor and application thereof
    Patent number: 11926687
    Abstract: A grafted polypropylene resin is prepared by a grafting reaction of a polar monomer capable of absorbing microwave so as to raise its temperature in a microwave field to more than 200° C. and a solid polypropylene resin using microwave irradiation without adding an initiator. The polar grafted polypropylene resin that does not contain initiator residues and does not have a significant reduction in molecular mass compared with a resin before grafting is obtained.

  • Continuous operation method for microwave high-temperature pyrolysis of solid material comprising organic matter
    Patent number: 11926794
    Abstract: A continuous operation method is employed for the microwave high-temperature pyrolysis of a solid material containing an organic matter. The method includes the steps of mixing a solid material containing an organic matter with a liquid organic medium; transferring the obtained mixture to a microwave field; and in the microwave field, continuously contacting the mixture with a strong wave absorption material in an inert atmosphere or in vacuum. The strong wave absorption material continuously generates a high temperature under a microwave such that the solid material containing an organic matter and the liquid organic medium are continuously pyrolyzed to implement a continuous operation.

  • Mixed oxide nanoparticles and apparatus for making same
    Publication number: 20020187889
    Abstract: An apparatus for producing mixed oxide nanoparticles uses thermophilic bacteria cultured with suitable reducible metals in the presence of an electron donor to reduce at least one metal to form mixed oxide nanoparticles. The mixed oxide nanoparticles can have a magnetism greater than magnetite, such as a line width (&Dgr;H) of at least 2,200 Gauss. The magnetic nanoparticles can be used to form improved magnetorheological media, magnetic storage, dry printing and magnetic devices.

  • Mixed oxide nanoparticles and method of making
    Patent number: 6444453
    Abstract: Methods and apparatus for producing mixed oxide nanoparticulates are disclosed. Selected thermophilic bacteria cultured with suitable reducible metals in the presence of an electron donor may be cultured under conditions that reduce at least one metal to form a doped crystal or mixed oxide composition. The bacteria will form nanoparticles outside the cell, allowing easy recovery. Selection of metals depends on the redox potentials of the reducing agents added to the culture. Typically hydrogen or glucose are used as electron donors.
