  • Publication number: 20240184597
    Abstract: This application provides a display method and an electronic device. The method includes: playing a first transition animation in normal order on a desktop on a display of the electronic device; and playing the first transition animation in reverse order on a screen offscreen after switching from the desktop to the screen off screen on the display of the electronic device. In this way, a transition animation can be applied to more scenarios to improve user experience.

  • 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.
