  • Patent number: 11623204
    Abstract: A method for preparing a modified cellulose aerogel for glycoprotein separation is provided. In this method, cellulose aerogel is employed as a substrate. The cellulose aerogel is known to have a three-dimensional network structure with extremely high porosity and specific surface area and extremely low density. So, by using the cellulose aerogel as a substrate, it is possible to provide the glycoproteins to be separated with more binding sites. PEI dendrimer has abundant functional groups and can easily be modified. By modifying the cellulose aerogel substrate with the PEI dendrimer, it is possible to improve the density of the phenylboronic acid bound to the substrate, thereby leading to higher affinity toward the glycoproteins to be separated.

  • Patent number: 11603629
    Abstract: A container and a preparation method thereof are provided. A material forming the container includes at least two types of oxidized nanocelluloses interlaced with each other, the at least two types of oxidized nanocelluloses being configured to have different degrees of expansion after absorbing moisture in a same environment. In a dry condition, the at least two types of oxidized nanocelluloses do not expand, so the structure of the container is relatively dense and the air permeability is poor, which can sufficiently maintain moisture of an article stored in the container. In case the article itself or other reasons cause high humidity, different oxidized nanocelluloses of the container expand after absorbing moisture, so that gaps between different oxidized nanocelluloses becomes larger, and the air permeability of the container becomes better, which can discharge excessive moisture, enabling the container to self-adjust the air permeability based on humidity.

  • Patent number: 11584688
    Abstract: A visible-light-photocatalyzed composite light-transmitting concrete contains several bundles of optical fibers, the optical fibers are coated with a protective layer on their outer surface, the protective layer contains a visible light photocatalyst, and the concrete has several gas-permeable pores. Such concrete is prepared by mixing a visible light photocatalyst and a light-transmitting glue, applying the mixture to the surface of optical fibers to form a protective layer, and using optical fibers in the concrete. The resulting concrete has dual properties of light transmittance and photocatalytic oxidation of gas-phase pollutants under visible light irradiation. The visible-light-photocatalyzed composite light-transmitting concrete significantly breaks through the limitation of photocatalytic concrete to light sources, so that gas-phase pollutants can be removed under visible light irradiation through photocatalysis of light-transmitting concrete.
