An intermetallic Au3Cu nanoprism exhibits exotic electron diffraction patterns that reflect multiple levels of atom stacking hierarchy (false-color coded). A particle library synthesized from location-specific polymer nanoreactor arrays was generated and studied by correlative electron microscopy to discover new nanocrystal structures like this.

An example of astrophotography of M27 (a planetary nebula in Vulpecula, also known as the Dumbbell Nebula) captured by the remote telescope system we implemented in Aksu City, China. Three channels obtained through Sloan g’, r’ and i’ filters were mixed with a white-light image. Designed with Shenming Fu.
