  • Patent number: 11878909
    Abstract: A method for preparing modified graphene and a method for preparing a slurry containing the modified graphene are disclosed. The method for preparing a modified graphene comprises: putting a flake graphite powder, a silicon molecular modifier, water and a boric acid solution into a high pressure container, filling a liquid gas into the high pressure container, connecting the high pressure container to a solid gas preparation apparatus, to solidify the liquid gas and obtain a solid gas, putting the solid gas into a ultraviolet washing machine for ultraviolet high-energy radiation, exfoliating the graphene flake, continuously exposing to ultraviolet light for a period of time to form a modified graphene, continuously exposing the modified graphene under the ultraviolet light, and storing the modified graphene in vacuum as an intermediate.

  • Publication number: 20230039006
    Abstract: The present disclosure belongs to the technical field of coatings, and in particular relates to a graphene-modified silicon-titanium nano-polymer slurry, and a preparation method and use thereof. When the graphene-modified silicon-titanium nano-polymer slurry provided by the present disclosure is added to a polymer coating, the high resistance of graphene to gas and liquid permeation and the silicon-titanium graphene network structure can significantly increase the resistance of a formed coating layer to medium permeation; due to the corrosion resistance of graphene, titanium, and silicon nanoparticles, a formed coating layer has very high stability, is not easy to react with various media such as an acid, an alkali, and a salt, is not easily consumed to form pores, and is not easy to react with corrosive media to generate soluble salts or cathodic loose and expanded products, which ensures the long-term stability of a composition and a structure of the coating layer.

  • Patent number: 11497417
    Abstract: An embodiment in accordance with the present invention includes a technology to continuously measure patient mobility automatically, using sensors that capture color and depth images along with algorithms that process the data and analyze the activities of the patients and providers to assess the highest level of mobility of the patient. An algorithm according to the present invention employs the following five steps: 1) analyze individual images to locate the regions containing every person in the scene (Person Localization), 2) for each person region, assign an identity to distinguish ‘patient’ vs. ‘not patient’ (Patient Identification), 3) determine the pose of the patient, with the help of contextual information (Patient Pose Classification and Context Detection), 4) measure the degree of motion of the patient (Motion Analysis), and 5) infer the highest mobility level of the patient using the combination of pose and motion characteristics (Mobility Classification).
