  • Patent number: 11866537
    Abstract: The present invention discloses an easy-to-process, opaque and high-impact methyl methacrylate-butadiene-styrene (MBS) polymer for polyvinyl chloride (PVC) and a preparation method thereof, and relates to the technical field of preparation of PVC additives. The easy-to-process, opaque and high-impact MBS for PVC has a core-kernel-shell (three-layer) structure, and includes the following components by mass: 1-20% of core, 70-85% of kernel and 5-20% of shell. The core is a semi-hard, lightly crosslinked copolymer of a styrene (St) monomer and an acrylate monomer. The kernel is a soft, lightly crosslinked butadiene (BD)-St polymer with a low glass transition temperature. The shell is a copolymer of St, butyl acrylate and methyl methacrylate (MMA) with a high glass transition temperature. The present invention solves the problems of low impact strength and poor processing fluidity of the existing MBS for opaque PVC products.

  • Publication number: 20200405823
    Abstract: Alcohol intoxication causes serious diseases, whereas current treatments are mostly supportive and unable to remove alcohol efficiently. Upon alcohol consumption, alcohol is sequentially oxidized to acetaldehyde and acetate by the endogenous alcohol dehydrogenase and aldehyde dehydrogenase, respectively. We disclose a hepatocyte-mimicking antidote for alcohol intoxication through the co-delivery of the nanocapsules of alcohol oxidase (AOx), catalase (CAT), and aldehyde dehydrogenase (ALDH) to the liver, where AOx and CAT catalyze the oxidation of alcohol to acetaldehyde, while ALDH catalyzes the oxidation of acetaldehyde to acetate. Administered to alcohol-intoxicated mice, the antidote rapidly accumulates in the liver and enables a significant reduction of the blood alcohol concentration. Moreover, blood acetaldehyde concentration is maintained at an extremely low level, significantly contributing to liver protection.

  • Patent number: 10668517
    Abstract: A metal shell of an electronic device and a method for fabricating the metal shell are provided. The method for fabricating the metal shell includes: stamping out a side wall and a bottom portion of the metal shell from a metal sheet, wherein the stamping retains a reserved material at a first position on the side wall; bending and shoving the reserved material on the side wall towards an inner side of the side wall, until a protruding portion is formed at the inner side of the side wall; removing an excessive portion of the protruding portion to shape the protruding portion into a plastic gripping structure of a preset shape; and injecting and filling the plastic gripping structure with plastic.

  • Patent number: 9472602
    Abstract: A display device is provided. A photovoltaic material (61) is evenly disposed in a display layer (6), so that an array formed by the photovoltaic material (61) forms light transmitting units (62) and the photovoltaic material (61) forms a path. Light emitted by a backlight layer (5) and ambient light are absorbed without affecting the light emission of the display layer (6), and are converted into current. When the current converted from light energy is used for a mobile terminal, the stand by time of the mobile terminal may be increased.
