Abstract: A method for preparing carbon black from pyrolysis char of waste tires by a molten salt thermal treatment and a product thereof are provided. The method includes heating one or two groups of a metal chloride salt group and a metal sulfate group to obtain a molten salt; adding pyrolysis char of waste tires into the molten salt and subjecting same to a molten salt thermal treatment under a preset reaction atmosphere; after the reaction is complete, separating the reaction product to obtain a secondary molten salt and treated pyrolysis char, washing the treated pyrolysis char with hot water and then drying same so as to obtain carbon black, and at the same time, recycling the secondary molten salt.

Abstract: A method of treating neurodegeneration and/or neurodegenerative condition, disease, or disorder caused by and/or associated with elevated or aberrant 15-PGDH activity in a subject in need thereof includes administering to the subject a therapeutically effective amount of a 15-PGDH inhibitor.

Abstract: A 3DP preparation process of a high-strength rapid-dissolving magnesium alloy for an underground temporary plugging tool is disclosed by the present disclosure, comprising the following steps: 1) evenly mixing ingredients of material components; 2) importing the shape of a product needing to be printed into a computer control system, and printing alloy powder and glue in a 3D printer in an alternate spraying molding mode to obtain a blank with the needed shape; 3) drying the blank obtained in the step 2) and then carrying out degreasing and sintering in a protective atmosphere or vacuum; and 4) sintering the blank obtained in the step 3) at a high temperature of 570° C.-680° C. in the protective atmosphere or vacuum and then cooling to a room temperature.
