资源简介：
In a previous ID10 experiment, a novel setup, coupling GISAXS with a quartz crystal microbalance (QCM) was successfully tested. The simultaneous use of these two in situ techniques provides an unprecedented view on the early stages of surface induced nucleation, with the ability to probe nuclei size, shape and spatial organization (GISAXS), as well as their elastic properties and mass (QCM), and the evolution of all these parameters over time. Here, we aim to use this technique to study the universality of the amorphous precursor nucleation pathway when nucleation takes place at an interface. The aim of this new experiment is (1) to acquire QCM and GISAXS data for systems for which we know (from ex situ external characterization) that nucleation at interfaces proceeds via amorphous intermediates (CaCO3 on quartz and mica), and (2) to evaluate the universality of this pathway for other substrates.
