Abstract: A nanocellular single crystal nickel based material is provided having a thermal diffusivity in the range of 0.0002 cm̂2/s to 0.02 cm̂2/s and a thermal conductivity in the range of 0.024 W/mK to 9.4 W/mK. The nanocellular single crystal nickel based material may be used to form turbine engine components. The nanocellular single crystal nickel based material may be produced by providing a first solution containing a nickel precursor and deionized water, providing a second solution containing a structure controlling polymer/surfactant and an alcohol, mixing the first and second solutions into a solution containing a reducing agent to form a third solution, and processing the third solution to create the nanocellular single crystal based material.

Abstract: A method of treating a carbon electrode includes providing a carbon-based electrode that has a surface with chemically different carbon oxides. The surface is treated with a reducing agent to reduce at least a portion of the oxides to a target carbon oxide. In an aspect, a method of treating a carbon electrode includes providing a carbon-based electrode that has a surface with an initial non-zero concentration of a target carbon oxide. The surface is then treated with a reducing agent to increase the initial non-zero concentration of the target carbon oxide.
