  • Publication number: 20210134497
    Abstract: The present invention provides fine grain structures for rare earth permanent magnets (REPMs) and their production in a manner to significantly enhance flexural strength and fracture toughness of the magnets with no or little sacrifice in the hard magnetic properties. The tough REPMs can have either homogeneous or heterogeneous refined grain microstructural architectures achieved by introducing a small amount of additive particle materials into the magnet matrix, such as fine-sized, insoluble, chemically stable, and non-reactive with the magnet matrix. These additive materials can act effectively as both heterogeneous nuclei sites and grain growth inhibitors during the heat treatment processes, which in turn resulting in refined grain structures of the REPMs. Alternatively, the fine grain structures were also achieved by using magnet alloy feedstock powders with finer particle sizes.

  • Publication number: 20200378018
    Abstract: The present invention discloses a carbon dots-based photocatalytic electrode for simultaneous organic matter degradation and heavy metal reduction and preparation method and use thereof, which belong to the field of multifunctional environmental materials and water treatment. With respect to the insufficient ability of simultaneous organic matter degradation and heavy metal reduction of existing photocatalytic electrodes, the present application provides a photocatalytic electrode with a Z-type heterojunction structure constructed by using carbon dots (CDs) as an electronic assistant. The directional transfer ability of photo-generated electrons is improved, while the recombination efficiency of photo-generated electrons and holes is reduced. The performance of a photocatalytic electrode in simultaneous organic matter degradation and heavy metal reduction is thereby improved.

  • Patent number: 10323865
    Abstract: A compact cooling system based on thermoelastic effect is provided. In one embodiment, the system comprises a pair of rollers serving as a heat sink, stress applicator and belt drive, a cold reservoir and a solid refrigerant belt coupled to the cold reservoir and to the heat sinks to pump heat from the cold reservoir to the heat sink. The refrigerant belt comprises solid thermoelastic materials capable of thermoelastic effect. The refrigerant material is mechanically compressed when entering the gap of the roller and subsequently released after passing through. When compressed the refrigerant material transforms to martensite phase and releases heat to the roller and neighboring materials. After released by the rollers, the refrigerant material transforms back to austenite and absorbs heat from the ambient atmosphere.
