Nanocrystals behave like atoms and have ability to spontaneously self-assemble into periodically ordered structures, in which these nanocrystal-packed solids are called as “supercrystals”. The supercrystals represent completely the new category of condensed matters, enabling manifestations of a variety of new phenomena and technological applications. To facilitate the discovery of assembled superlattice diagram and associated property, we developed a series of synchrotron-based techniques, which synchronize SAXS and WAXS as well as various spectroscopy together, to in-situ monitor the assembly process and property manifestation as well as structural reconstruction of nanocrystal superlattices with subsequent materials processing under various environments. I will introduce synchrotron-based X-ray techniques developed at CHESS, and highlight several scientific cases of nanocrystal assembles, which can stimulate the nanocrystal assemble community to take advantage of synchrotron x-rays to perform their breakthrough research towards fast discovery and controlled design  of novel materials.   <br/>
