Fig. 1. Top-down (a) and bottom-up (b) steps of nanomaterial synthesis. (c) Glass, crystalline, ceramic material is tuned via initial composition of a photo-curable precursor mixture and its thermal annealing at the required temperature, pressure, gas ambience. Surface tension driven reshaping is shown in scanning electron microscopy images in (b), where the same scale applies to both images before and after high temperature annealing.
