Abstract: Methods disclosed herein include using additive manufacturing to create a joint between a first metallic material and a second metallic material that is different from the first metallic material, wherein the porosity of the joint is less than about 0.1 percent by volume measured according to ASTM B-962. The additive manufacturing can be performed such that no intermetallic brittle phase forms between the first metallic material and the second metallic material.

Abstract: Oxygen-containing graphenic nanomaterial (OGN)-doped novolac polymers suitable for producing graphitized carbon may be synthesized based on a correlation between (a) the amount of OGN and/or the oxygen content of the OGN and (b) at least one property of a resultant graphitized carbon. For example, a method may comprise: synthesizing an OGN-doped novolac polymer, wherein an amount of OGN and/or an oxygen content of the OGN used in the synthesizing is based on a correlation between (a) the amount of OGN and/or the oxygen content of the OGN and (b) at least one property of a resultant graphitized carbon; and carbonizing and graphitizing the OGN-doped novolac polymer to yield a graphitized carbon.
