Various embodiments of the present disclosure provide methods of making wellbore fluids with enhanced electrical conductivities. In some embodiments, such methods comprise: (1) pre-treating a carbon material with an acid; and (2) adding the carbon material to the wellbore fluid. Further embodiments of the present disclosure pertain to wellbore fluids formed by the methods of the present disclosure. Additional embodiments of the present disclosure pertain to methods for logging a subterranean well by utilizing the aforementioned wellbore fluids.

Carbonaceous nanoparticles as conductivity enhancement additives to water-in-oil emulsions, oil-in-water emulsions and oil-based wellbore fluids

Various aspects of the present invention pertain to methods of sorption of various materials from an environment, including radioactive elements, chlorates, perchlorates, organohalogens, and combinations thereof. Such methods generally include associating graphene oxides with the environment. This in turn leads to the sorption of the materials to the graphene oxides. In some embodiments, the methods of the present invention also include a step of separating the graphene oxides from the environment after the sorption of the materials to the graphene oxides. More specific aspects of the present invention pertain to methods of sorption of radionuclides (such as actinides) from a solution by associating graphene oxides with the solution and optionally separating the graphene oxides from the solution after the sorption.

In some embodiments, the present disclosure pertains to methods of preparing graphene nanoribbons from a graphene film associated with a meniscus, where the method comprises patterning the graphene film while the meniscus acts as a mask above a region of the graphene film, and where the patterning results in formation of graphene nanoribbons from the meniscus-masked region of the graphene film. Additional embodiments of the present disclosure pertain to methods of preparing wires from a film associated with a meniscus, where the method comprises patterning the film while the meniscus acts as a mask above a region of the film, and where the patterning results in formation of a wire from the meniscus-masked region of the film. Additional embodiments of the present disclosure pertain to chemical methods of preparing wires from water-reactive materials.
