  • 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: 10741708
    Abstract: According to some embodiments, the present invention provides a novel photovoltaic solar cell system from photovoltaic modules that are vertically arrayed in a stack format using thin film semiconductors selected from among organic and inorganic thin film semiconductors. The stack cells may be cells that are produced in a planar manner, then vertically oriented in an angular form, also termed herein tilted, to maximize the light capturing aspects. The use of a stack configuration system as described herein allows for the use of a variety of electrode materials, such as transparent materials or semitransparent metals. Light concentration can be achieved by using fresnel lens, parabolic mirrors or derivatives of such structures. The light capturing can be controlled by being reflected back and forth in the photovoltaic system until significant quantities of the resonant light is absorbed.

  • 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: 10053388
    Abstract: Compositions and methods for improved materials and material laminates with graphitic or inorganic/organic nanomaterials are presented. Graphitic or inorganic/organic nanomaterials, such as carbon nanotubes, carbon nanofibers, graphenes or graphene oxides, are introduced into an aqueous composition as fillers to provide a graphitic or inorganic/organic nanocomposite. Such composition may be used as laminates to improve adhesion between a film and a layer of material or between layers of materials and to increase not only strength properties, but also to provide other desired properties such as electronic properties, UV absorbing/blocking, optical-limiting, anti-reflective, fire-retardant, conducting, anti-microbial properties or pigmentation to say material. By tailoring the composite formulations with multiple graphitic or organic/inorganic nanomaterials, the resulting materials laminates become multifunctional and can be used for a variety of applications.
