Qian Chen has been an assistant professor in the Department of Materials Science and Engineering at the University of Illinois at Urbana-Champaign since 2015. She received her PhD degree from the same department in 2012. Her research focuses on electron microscopy-based imaging, understanding, and engineering of soft materials, such as nanoparticle and colloidal self-assembly, protein transformation, battery materials, and energy-efficient filtration. Her awards include the American Chemistry Society' (ACS) Victor K. LaMer Award in 2015, the Air Force Office of Scientific Research Young Investigator Program (AFOSR YIP) Award in 2017, the National Science Foundation CAREER Award in 2018, an Alfred P. Sloan Research Fellowship in 2018, and the ACS Unilever Award (2018). She also was recognized on the Forbes 30 Under 30 Science List in 2016. Chen can be reached by email at qchen20@illinois.edu .

N2 - This article reviews the advancements and prospects of liquid cell transmission electron microscopy (TEM) imaging and analysis methods in understanding the nucleation, growth, etching, and assembly dynamics of nanocrystals. The bonding of atoms into nanoscale crystallites produces materials with nonadditive properties unique to their size and geometry. The recent application of in situ liquid cell TEM to nanocrystal development has initiated a paradigm shift, (1) from trial-And-error synthesis to a mechanistic understanding of the synthetic reactions responsible for the emergence of crystallites from a disordered soup of reactive species (e.g., ions, atoms, molecules) and shape-defined growth or etching; and (2)A from post-processing characterization of the nanocrystals' superlattice assemblies to inA situ imaging and mapping of the fundamental interactions and energy landscape governing their collective phase behaviors. Imaging nanocrystal formation and assembly processes on the single-particle level in solution immediately impacts many existing fields, including materials science, nanochemistry, colloidal science, biology, environmental science, electrochemistry, mineralization, soft condensed-matter physics, and device fabrication.
