Project Details
Description
Traditional syntheses of zeolites convert a gel or gel-like mixture to a crystalline material under hydrothermal conditions. One of the major questions in zeolite crystallization concerns the mechanisms in the earliest stages. We plan to use an in-situ combination of diffraction and spectroscopy to probe the crystallization. The in-situ cell will be adopted from BM26 (BUBBLE) beamline, where it has been used with success for combined SAXS/WAXS measurements.
