    摘要: The present disclosure provides a method for preparing a high cohesive energy adsorbent for fluoride removal, which includes the following steps: S1. adding NaHF2—NiF·6H2O additive to SiCO ceramic powder, and sintering at a temperature of 310-330° C. for 18-22h to obtain a sintered substance; S2. grinding the sintered substance to obtain particles with a size of 2-3 mm, and mixing the particles with polyacrylonitrile to form a composite polymer; and S3. molding the composite polymer by a vacuum baking process at a temperature of 75-85° C., then performing ball milling and sieving to obtain the high cohesive energy adsorbent for fluoride removal. The high cohesive energy adsorbent for fluoride removal may be used in the adsorption and separation of the C2F6—CHF3—CClF3 mixture system, and the contents of CHF3 and CClF3 are lowered to less than 10ppmv.

    摘要: A medial buttress construct for femoral neck includes a support part and an attachment fixing part fixedly connected to each other. The support part includes a structure matching an inferior surface of a proximal end of the femoral neck. The attachment fixing part includes structures simultaneously matching a front side surface of a distal end of the femoral neck and a front side surface of an upper end of femoral shaft. The attachment fixing part includes at least one opening for allowing a screw to pass through the structure matching the front side surface of the distal end of the femoral neck, and at least one opening for allowing a screw to pass through the structure matching the front side surface of the upper end of the femoral shaft. A fracture fixation device for femoral neck may include the medial buttress construct for femoral neck.

    摘要: A power supply device includes a first body and a second body. The first body has an opening and an adapter module which is electrically connected to a first electronic device. The opening is divided into a first part and a second part via a first axis, and the shape of the first part is asymmetrical to the shape of the second part. The second body has an energy storage unit. The energy storage unit is electrically connected to the adapter module to supply power to the first electronic device, when the second body is detached from the first body, the energy storage unit is adapted to supply power to a second electronic device.

    摘要: A reception chair includes a frame assembly, a seat, and a back coupled together. The frame assembly includes front legs, rear legs, and a support coupled to the front and rear legs. The seat is provided, on a front portion of a bottom surface thereof, with collars, which are arranged to respectively correspond to the front legs of the frame assembly so that upper ends of the front legs are insertable and fit into the collars. The seat is provided, on a rear portion of the bottom surface thereof, with fixing sections, such that the fixing sections and the rear legs of the frame assembly correspond to each other, respectively. The fixing sections each include a first mounting member and a second mounting member, such that the fixing sections of the seat and the rear legs collectively form enclosing coupling connection structures therebetween.
