Title: Probing the self-assembly of nanostructures in action: real-time grazing-incidence small-angle x-ray scattering.

Abstract

Although highly ordered nanostructures can often form in a self- assembled fashion, the formation of the structures can be extremely dynamic, far from commonly believed near-equilibrium conditions even at the end of the ordering processes. Therefore, a controlled self-assembling of the nanostructure has to be guided by a thorough understanding of ordering kinetics and nanoparticle dynamics in the complex matrices. For probing the systems involving dynamical structure of surfaces and buried interfaces, many x-ray surface and interfacial characterization techniques provides a unique scientific opportunity to study the principle of formation of ordered nanostructures. As an increasingly important structural-characterization technique, grazing-incidence small-angle scattering (GISAXS) finds vast applications in nanostructures and nanocomposites at surfaces and interfaces for in situ and real-time studies because of its probing q-range (0.001-1 nm{sup -1}) and temporal resolution (0.001-1 s). At the Advanced Photon Source (APS), we pioneered in using real-time GISAXS to study nanoparticle/polymer nanocomposites. Also, the kinematics of nanoparticle crystal formation at air/liquid interfaces has been elucidated by the similar method during the liquid droplet evaporation. Recently, we used in situ GISAXS to investigate nucleation behavior of sol-gel derived oxide thin films.
