Nanostructured Carbon: Structural Rigidity and Thermal Conductance Exploration

This study delves into the potential of nanostructured carbon foams, investigating their structural rigidity and thermal conductance properties. The research optimizes the structure, examines elastic properties, and explores electronic structures. Graphitic foam properties and hybrid graphite-diamond morphology are analyzed in detail to determine their suitability as advanced materials. The study reveals that graphitic foam exhibits metallic characteristics with a high density of states per electronvolt per spin near the Fermi energy level.
