  • Publication number: 20240338531
    Abstract: A chatbot system is configured to execute code to perform determining, by the chatbot system, a classification result for an utterance and one or more anchors each anchor of the one or more anchors corresponding to one or more anchor words of the utterance. For each anchor of the one or more anchors, one or more synthetic utterances are generated, and one or more classification results for the one or more synthetic utterances are determined. A report is generated by the chatbot system including a representation of a particular anchor of the one or more anchors, the particular anchor corresponding to a highest confidence value among the one or more anchors. The one or more synthetic utterances may be used to generate a new training dataset for training a machine-learning model. The training dataset may be refined according to a threshold confidence values to filter out datasets for training.

  • Publication number: 20230151224
    Abstract: In an embodiment, the present disclosure pertains to a method of coating a substrate to impart antiviral and water resistance to the substrate. In general, the method includes obtaining a substrate and applying a coating composition to the substrate. In some embodiments, the coating composition imparts antiviral and water resistance properties to the substrate. In some embodiments, the coating composition has an antiviral method of action against a virus by causing damage to at least one of a capsid of the virus, an outer envelope of a protein layer of the virus, a spike protein of the virus, a cellular membrane of the virus, or combinations thereof.

  • Publication number: 20220259442
    Abstract: A process for manufacturing the composition coating may include selecting a wood or masonry material substrate and utilizing a sol-gel comprising a silane or silane derivative and metal oxide precursor to coat the substrate. The process may utilize an all solution process or controlled environment for manufacturing a composition coating that prevent wetting and/or staining of a substrate. The composition coatings for treating wood or masonry materials improves weather-resistance, microbial resistance, stain-resistance and fungal-resistance of the materials. The reduced permeability of the resulting masonry materials can also delay or inhibit degradation caused by permeation of ions such as chlorides and sulfates. In addition, a stain comprising the composite solution and pigments may impart additional property to wood or masonry materials whilst retaining or improving the original appearance, particularly for the visibility and contrast of the wood grain as seen after the application of the coating.

  • Patent number: 11142867
    Abstract: A process of fabricating the waterproof coating may include selecting a textile material substrate, utilizing a sol-gel comprising a silane or silane derivative and metal oxide precursor to coat the substrate, and optionally coating the substrate with a hydrophobic chemical agent and/or other chemical agents to create a surface with nanoscopic or microscopic features. The process may utilize an all solution process or controlled environment for fabricating a fluorine-free waterproof coating that prevent wetting or staining of a substrate, or may utilize a controlled environment. The composition coatings for treating textile materials improve soil-resistance and stain-resistance of the textile materials while the compositions contain no fluorine-based chemicals. In addition, the composite solution may impart additional properties such as physical strength to the textile whilst retaining the original appearance.

  • Patent number: 10240010
    Abstract: A composition and method for fabricating graphitic nanocomposites in solid state matrices is presented. The process for fabricating graphitic nanocomposites in solid state matrices may include selecting one or a mixture of specific graphitic nanomaterials. The graphitic nanomaterial(s) may be functionalizing with a moiety similar to the building blocks of the solid state matrices. The functionalized graphitic nanomaterials are mixed with the building blocks of the solid state matrices. The mixture may be cured, which causes in situ formation of the sol-gel solid state matrices that entraps and/or covalently links with the graphitic nanomaterials during the network growing process. This process allows the nanomaterials to be introduced into the matrices homogeneously without forming large aggregations.

  • Patent number: 10208172
    Abstract: An improved graft polymerization method from general graphitic structures with organic based monomers through the mechanism of Reversible Addition-Fragmentation Chain Transfer (RAFT) polymerization was developed. Organic hybrid nanomaterials comprising graphitic structures are covalently bonded via chemically reactive groups on the outer walls of the structure. Methods for forming the covalently bonded structures to many organic based monomers and/or polymers may occur through RAFT polymerization utilizing dithioester as a chain transfer agent. The method may also comprise nanocomposite formation of such organic hybrid nanomaterials with common plastic(s) to form graphitic nanocomposite reinforced plastic articles.
