Direct observation of Cu in high-silica chabazite zeolite by electron ptychography using Wigner distribution deconvolution

Scientific Reports, 2023
Direct observation of Cu in Cu-chabazite (CHA) zeolite has been achieved by electron ptychography using the Wigner distribution deconvolution. The imaging properties of ptychographically reconstructed images were evaluated by comparing the intensities of
