Division/Committee: [COLL: Division of Colloid and Surface Chemistry]

Recent years, researchers have witnessed rapid progresses in imaging methods with atomic to tens of nm resolution—way beyond the diffraction limit of optical microscopy. This symposium will focus on how these imaging methods provide new insights into a series of fundamental and application-related questions in colloidal chemistry, such as solvent-mediated colloidal interactions, fluid/solid‒fluid interface structures, self-assembly, polymer phase transition, plasmonics, chemo-mechanical coupling, and protein transformation. Particular attentions will be given to the challenges that scientists have tackled and are facing in adapting these nanoscopic imaging methods, such as electron microscopy, atomic force microscopy, and electron/X-ray tomography, for colloidal nanoparticle suspensions, their superstructures, patterned surfaces, etc. We will also discuss correlative characterization, data science, integration of experimental imaging with simulation and theoretical modeling, and related applications. Topics include, but are not limited to: • Synthesis and growth mechanism of colloidal nanoparticles • Equilibrium and out-of-equilibrium self-assembly • Liquid-phase scanning/transmission electron microscopy, atomic force microscopy, electron/X-ray tomography • Function mapping: plasmonics, photon-phonon coupling • Energy storage and conversion: catalysis and battery • Structured interface/interphase
