Abstract: A FRP rebar composition includes 15-45 vol % of a polymer matrix and 55-85% of a fiber mixture in which the fiber mixture includes 50-70 vol % of a first plurality of fibers which include carbon fibers and 30-50 vol % of a second plurality of fibers which are selected from the group consisting of PET fibers, glass fiber, and combinations thereof. A method of forming a FRP rebar includes feeding a first plurality of fibers and a second plurality of fibers simultaneously into a resin impregnator, pulling the fiber mixture through a liquid polymeric resin in the resin impregnator to form a resin-soaked fiber mixture, and passing the resin-soaked fiber mixture through a heated stationary die.

Abstract: A functionalized inorganic filler includes a dendritic fibrous nanoparticle that has a surface functionality including at least one amine functional group linked to a surface of the dendritic fibrous nanoparticle. A method of making a functionalized inorganic filler includes reacting an inorganic particle precursor and a shape-directing agent to provide a dendritic fibrous nanoparticle, then reacting the dendritic fibrous nanoparticle with a reactive compound that has at least one amine functional group to form the functionalized inorganic filler. A polymer composite includes an epoxy-based polymer matrix and a functionalized inorganic filler.

Abstract: Provided is a process that may comprise cooling an engine exhaust emissions comprising SOx on a vehicle that may come from an engine. The cooled engine exhaust emissions comprising SOx may be passed to one or more absorption units. The SOx may be extracted from the engine exhaust emissions with a sorbent supported on solid porous media in an absorption unit on the vehicle to form an absorbed SOx. The absorbed SOx may be desorbed, followed by forming one or more SOx product from the desorbed SOx. The one or more SOx product may be unloaded to an off-vehicle facility.

Abstract: Systems and methods for treating automotive vehicle emissions on board an automotive vehicle include the use of waste heat recovery, electrochemical water splitting, phototcatalytic water splitting, and selective catalytic reduction. Waste heat recovery is used to power electrochemical water splitting, or photocatalytic water splitting. Photons collected from a solar panel are used in photocatalytic water splitting, or in photo-assisted selective catalytic reduction. Hydrogen gas generated by water splitting is used in conjunction with catalytic reduction units to catalytically reduce NOx in an engine exhaust gas.

Abstract: An integrated method for mesophase pitch and petrochemicals production. The method including supplying crude oil to a reactor vessel; heating the crude oil in the reactor vessel to a predetermined temperature for a predetermined amount of time; reducing asphaltene content in the crude oil by allowing polymerization reactions to occur in the reactor vessel at an elevated pressure in the absence of oxygen; producing a three-phase upgraded hydrocarbon product comprising gas, liquid, and solid hydrocarbon components, where the liquid hydrocarbon component comprises deasphalted oil and the solid hydrocarbon component comprises mesophase pitch; separating the gas, liquid, and solid hydrocarbon components; directly utilizing the liquid hydrocarbon component for petrochemicals production; and directly utilizing the solid hydrocarbon component for carbon artifact production.
