  • Patent number: 11820679
    Abstract: Disclosed are an energy self-sufficient high-efficiency photothermal evaporative nano-particle porous membrane and application thereof, including: dissolving polymer A in solvent B to obtain solution A; dripping solution A into solvent C to obtain a polymer A nano hydrogel dispersion; evenly mixing polymer A nano hydrogel dispersion and nano particle dispersion of photothermal conversion material D to obtain a co-blended dispersion; performing suction-filtering to the co-blended dispersion on a surface of a solvent-resistant membrane E to form an A-D co-blended membrane; and performing suction-filtering to a solvent F using the A-D co-blended membrane, followed by drying to obtain a high-efficiency photothermal evaporative nano-particle porous membrane.

  • Publication number: 20230330726
    Abstract: The present disclosure discloses a method for targeted regulation of soil microbes to synchronize heavy metal/metalloid transformation and greenhouse gas emission reduction and use. The present disclosure discovers that by compounding methionine with an organic acid salt, the obtained formulation can significantly increase the ability of the soil microbes to promote arsenic methylation in a targeted mode, and meanwhile, and the methane production is effectively reduced in the presence of the methionine. In the present disclosure, the methionine/organic acid salt formulation is further loaded into a modified biochar material of a porous structure, so as to achieve the effect of slow release. The method of the present disclosure may effectively reduce absorption of inorganic arsenic by rice, achieve a significant reduction in the proportion of inorganic arsenic in the total arsenic in the rice and inhibit methane emission of the soils and reduce methane emission at the same time.
