Colloidal crystals reflecting interference‐based structural colors have been reported in many organisms, but are yet to be accurately described. Herein, the bright, iridescent scales of green and blue Glenea celestis beetles investigated using optical ultrastructural techniques. The studies based on focused ion‐beam scanning electron microscopy synchrotron small‐angle X‐ray scattering data reve...
Crystal phase regulations may endow materials with enhanced or new functionalities. However, syntheses of noble metal-based allomorphic nanomaterials are extremely difficult, and only a few successful examples have been found. Herein, we report the discovery of hexagonal close-packed Pt-Ni alloy, despite the fact that Pt-Ni alloys are typically crystallized in face-centred cubic structures. The...
Orderly arrayed granular crystals exhibit extraordinary capability to tune stress wave propagation. Granular system of higher dimension renders many more stress wave patterns, showing its great potential for physical and engineering applications. At nanoscale, one-dimensionally arranged buckyball (C60) system has shown the ability to support solitary wave. In this paper, stress wave behaviors o...
