A method of producing dispersed of high quality graphene/graphite oxides in a powder matrix to then be reacted to form a composite. Where the powders have similar hydrophobicity and the graphene/graphite oxides has minimal surface oxidation or minimal epoxy group and where the powders are sonically mixed.

A low carbon footprint material is used to decrease the carbon dioxide emission for production of a high carbon footprint substance. A method of forming composite materials comprises providing a first high carbon footprint substance; providing a carbon nanomaterial produced with a carbon-footprint of less than 10 unit weight of carbon dioxide (CO.sub.2) emission during production of 1 unit weight of the carbon nanomaterial; and forming a composite comprising the high carbon footprint substance and from 0.001 wt % to 25 wt % of the carbon nanomaterial, wherein the carbon nanomaterial is homogeneously dispersed in the composite to reduce the carbon dioxide emission for producing the composite material relative to the high carbon footprint substance.

An electrical grounding assembly includes an electrically conductive metal grounding plate, and a corrosion-protective jacket enclosing the grounding plate. The jacket is electrically conductive and water impermeable. The electrical grounding assembly further includes an electrically conductive line having a first end in electrical contact with the grounding plate and enclosed in the jacket, and an opposed second end outside of the jacket for connection to a structure to be electrically grounded.

A method of sealing propagating cracks in a sensor-laden cement sheath comprising the steps of monitoring an electrical resistivity of the sensor-laden cement sheath to produce a measured value, wherein the sensor-laden cement sheath comprises a conductive sensor, an on-demand expanding agent, and a cement, activating a heat source when the measured value of the electrical resistivity is greater than an activation threshold, increasing a temperature of the sensor-laden cement sheath with the heat source to an activation temperature, wherein the activation temperature is operable to initiate a reaction between the on-demand expanding agent and water, wherein the activation temperature is greater than a formation temperature, reacting the on-demand expanding agent with water to produce a swelled agent, wherein the swelled agent occupies a greater volume than the on-demand expanding agent, and sealing the propagating cracks in the sensor-laden cement sheath with the swelled agent.
