Abstract:
A carbon composite comprises a binder and carbon microstructures having interstitial spaces among the carbon microstructures and voids within carbon microstructures; wherein the binder is disposed in the interstitial spaces among the carbon microstructures and the voids within the carbon microstructures. Alternatively, a carbon composite comprises carbon microstructures and a binder disposed in the interstitial spaces among the carbon microstructures, wherein the carbon microstructures comprise less than about 15 volume percent of voids within the carbon microstructures based on the total volume of the carbon microstructures.

Abstract:
A system comprises a casing and a liner. The liner is concentric with the casing and the casing is disposed in a borehole. A layer of material disposed between the liner and the casing. The layer of material forms a first bond with the liner and a second bond with a metal alloy disposed on an inner surface of the casing thereby enabling hanging the liner from the casing. The layer of material is an expandable metal disposed upon a tapered surface of the liner. The layer of material contacts the metal alloy along a circumferential surface of the layer of material. The layer of material comprises a product of an exothermic reaction package; where a product is produced by an exothermic reaction of a metal with a metal alloy.
