title: Replication of spinodally decomposed structures with structural coloration from scales of the longhorn beetle Sphingnotus mirabilis.
abstract: Scales of the longhorn beetle Sphingnotus mirabilis possess a disordered bicontinuous macroporous structure that resembles a structure formed by a phase-separation process of spinodal decomposition. By using the scales as templates, SiO2 and TiO2 structures were successfully replicated. Structural and optical characterizations show that the fabricated oxide structures are spinodal decomposition structures with only short-range order and display non-iridescent structural colors.
