This weeks image comes from a recent Journal of Physics: Condensed Matter paper by Yasuhiro Sakamoto for our special issue on Soft Quasicrystals.
Over the past decade quasicrystals have been reported in many soft-matter systems, thus extending the field of quasicrystals from the more traditional metallic-alloy materials to materials based on supramolecular building blocks such as dendrimers and diblock copolymers, nanoparticles, and colloidal particles.
In this work, Multimodal cage-type mesoporous silicas (MCMSs) with Frank–Kasper type square–triangle tiling are investigated by high resolution transmission electron microscopy (TEM).
Professor Sakamoto identified and characterized three defect structures, and explained them using polyhedral models, producing these stunning images in the process!
