  • Magnetic resonance system and shimming method and imaging method thereof
    Patent number: 11965945
    Abstract: Embodiments of the present application provide a magnetic resonance system and a shimming method and an imaging method thereof. The shimming method comprises: performing a scout scan on a subject to be examined, and obtaining phase data of a plurality of slice positions; determining three-dimensional space static magnetic field information according to the phase data of the plurality of slice positions; and determining a shimming value of a slice in a region of interest according to the three-dimensional space static magnetic field information.

  • Production of Graphene and Nanoparticle Catalysts Supported on Graphene Using Microwave Radiation
    Publication number: 20150087498
    Abstract: Microwave irradiation is used to synthesize graphene and metallic nanocatalysts supported on graphene either by solid or solution phase. In solid phase methods, no solvents or additional reducing agents are required so the methods are “environmentally friendly” and economical, and the graphene and nanocatalysts are substantially free of residual contaminants. Recyclable, high efficiency Pd nanocatalysts are prepared by these methods.
