Extended Data Fig. 7: iDPC-STEM images of the pyridine/ZSM-5 samples through heating.
From: Atomic imaging of zeolite-confined single molecules by electron microscopy
a, iDPC-STEM image before heating (saturated van der Waals adsorption). b, iDPC-STEM image after heating at 200 °C outside the scanning transmission electron microscope. c, Different kinds of pyridine configuration in ZSM-5 channels after heating. More magnified iDPC-STEM images of the near-horizontal pyridine configurations are given, the sizes of which agree with the model of pyridine molecules.
