Zeolite catalysts often display highly intergrown structures, yielding a zeolite “flower” or “sun” at the microscale. Using small‐angle X‐ray scattering and in situ fluorescence microscopy, Bert M. Weckhuysen et al. show in their Communication on page 13803 that porosity is developed only in specific segments of zeolites, which might cause strong local discrepancies in performance and deactivation behavior. The yellow sun against a black background is reminiscent of the symbol of Utrecht University, where the work was performed.
