Abstract: Robotic tools, methods, and systems for repairing pipes in-situ are described. A robotic tool includes a body with an annular, cylindrical configuration with a first end and a second end opposite the first end, the body having an inner surface defining an axis; a printing arm attached to the inner surface of the robotic body using a track, the printing arm circumferentially movable along the inner surface of the body; a printing head attached to the printing arm, the printing head movable radially along the printing arm and axially relative to the printing arm; and a plurality of legs positioned at axial intervals around the robotic body, each leg pivotably attached to the robotic body at either the first end or the second end of the body and pivotable between an open position and a closed position.

Abstract: Transparent articles and methods of producing transparent articles are provided. The transparent article includes hydrophobic nanoparticles dispersed within poly(methyl methacrylate). The method of producing transparent articles includes pouring a transparent article precursor into a mold, the transparent article precursor comprising nanoparticles, a solvent, and a polymer, and the mold comprising a flat surface. The method also includes placing the mold into a container having an adjustable opening and allowing the solvent to evaporate from the transparent article precursor, thereby forming the transparent article over the flat surface of the mold. The method further includes flattening the transparent article, in which flattening the transparent article includes positioning a flat article on a first side of the transparent article, and compressing the transparent article between the flat surface and the flat article.

Abstract: Nanocomposite compositions and methods for preparing nanocomposite compositions films are provided. The nanocomposite compositions include dendritic fibrous nanoparticles that have a diameter ranging from 50 to 500 nm, and a polymer matrix comprising poly(methyl methacrylate) (PMMA), where the dendritic fibrous nanoparticles have a hydrophobic coating and are dispersed within the PMMA matrix. Methods of preparing nanocomposite compositions may include introducing dendritic fibrous nanoparticles into a mixture with a poly(methyl methacrylate) and an organic solvent to form a composite solution. Methods further include casting the mixture onto a glass sheet within a mold, evaporating the organic solvent to form the nanocomposite film, and separating the nanocomposite film from the glass sheet.

Abstract: A fiber reinforced polymer rebar composition and a method of forming the rebar composition is described. The method includes the steps of feeding a first fiber and a second fiber simultaneously through a preforming guide into a resin impregnator, pulling the fibers through the liquid polymeric resin in the resin impregnator to form a resin-soaked hybrid fiber, and passing the resin-soaked hybrid fiber through a heated stationary die where the resin of the resin-soaked hybrid fiber undergoes polymerization and cross-linking.

Abstract: There is disclosed a mechanical coupling for two rebars. The coupling includes a first extremity disposed on a first of the two rebars, and a second extremity disposed on a second of the two rebars. Each of the first and second extremities are machined to effect an interlocking, form-fit connection between the two rebars, wherein the form-fit connection prevents separation of the extremities and inhibits axial displacement of the two rebars with respect to each other. The coupling further includes a covering disposed about the two extremities when the extremities are interconnected via the interlocking, form-fit connection. Also disclosed and described is a related method.
