Abstract: Methods include producing tunable carbon structures and combining carbon structures with a polymer to form a composite material. Carbon structures include crinkled graphene. Methods also include functionalizing the carbon structures, either in-situ, within the plasma reactor, or in a liquid collection facility. The plasma reactor has a first control for tuning the specific surface area (SSA) of the resulting tuned carbon structures as well as a second, independent control for tuning the SSA of the tuned carbon structures. The composite materials that result from mixing the tuned carbon structures with a polymer results in composite materials that exhibit exceptional favorable mechanical and/or other properties. Mechanisms that operate between the carbon structures and the polymer yield composite materials that exhibit these exceptional mechanical properties are also examined.

Abstract: Organically capped quantum dots are made by functionalizing the surfaces of QDs of various architectures with a combination of 6-mercaptohexanol (MCH) and 2-[2-(2-methoxyethoxy)-ethoxy]-acetic acid (MEEAA).

Abstract: Methods include determining a desired hysteretic curve that corresponds to a set of dynamic mechanical analysis parameters, where the desired hysteretic curve comprises elastic portions and plastic portions, and the elastic and plastic portions comprise specific desired shapes. A first tuned carbon is selected, the first tuned carbon facilitating achievement of a desired shape of a particular elastic portion of the hysteretic curve. One or more selected post-treatments is performed on the first tuned carbon to form a first post-treatment carbon, the selected post-treatment facilitating achievement of a desired shape of a particular plastic portion of the hysteretic curve. The methods also include combining the first post-treatment carbon with other materials that are used in components of the tire and curing the combination comprising the first post-treatment carbon and the other materials. Carbon and elastomer compounds are also disclosed.
