Some morphological parameters of the folds can be readily determined from the AFM line profiles, as shown by the red

Beyond molecular and biomolecular luminescent materials, colloidal luminescent nanomaterials have gained attention in recent years

In this study, the morphology and distribution of the microtrichia on the hindwings, elytra and abdomen were investigated in the Asian ladybeetle, Harmonia axyridis (Pallas, 1773). Then, an interlocking model describing the

• been under continuous investigation [3]. Forbes [6] first investigated the folding process of the hind wings of a beetle (Pachnoda marginata). When beetles are at rest, their wings will be folded and tucked under the elytra, and the folding process includes the lateral and longitudinal folding of the
