Abstract: The present disclosure discloses an application of cuprous sulfide in a recovery of Au (III) from aqueous solutions, which relates to the fields of hydrometallurgy and precious metal recovery. The method of the present disclosure uses cuprous sulfide nanoparticles to recover Au (III) from aquesous solution, and undergoes gold adsorption under mechanical stirring. The method described in the present disclosure can efficiently recover Au (III) from aqueous solutions, has good recovery effects on Au (III) from acidic waste liquid, and has the advantages of energy conservation, environmental protection, and low cost.

Abstract: The present invention relates to a modulator of 1,2,5-oxadiazole indoleamine-(2,3)-dioxygenase, a preparation method and use thereof, more particularly to compounds of Formula I and Formula II, an isomer thereof, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, and their use in preparing drugs for treating cancers, neurodegenerative diseases, eye diseases, mental disorders, depression, anxiety disorders, Alzheimer's diseases and/or autoimmune diseases. Specific meanings of R substituents in Formula I and Formula II are consistent with the description of the specification.
