The same properties also determine the pigments' lightfastness and electrochemical sensing performance. For sensing, the same properties of the oxides also facilitate their use as reliable electrochemical sensors by providing redox mediation, improved electrochemically active surfaces, and the conductive polymer- and vacancy-based charge transport required for improved electrochemical activity.

These concepts of using structure to create color for pigments is also applied to sensing materials by using certain (spinel, perovskite, and hexagonal/complex) oxides with mixed valence and defect-dominant frameworks.

In this study, the catalytic transformation from diamond into graphene or graphite (nickel (Ni) as a catalyst) is investigated through in-situ heating transmission electron microscopy (TEM). We demonstrate that the transition proceeds via a metal-induced solid-state mechanism that is driven by Ni catalysis and reaction-diffusion between Ni and carbon (C) atoms at elevated temperatures. Key processes include Ni grain migration and C–Ni interdiffusion. The annealing duration significantly influences the location and number of graphene layers. Notably, prolonged annealing causes the development of graphene on the Ni surface, whereas rapid, short-term annealing results in the formation of graphene at the diamond/Ni interface. Extended high-temperature exposure increases the number of graphene layers, potentially facilitating graphite formation.
