Abstract<\/h2>\n

Single atom detection in nanoporous materials is a significant challenge, particularly due to their sensitivity to electron irradiation.Here, natural beryl (Be3<\/sub>Al2<\/sub>Si6<\/sub>O18<\/sub>) is used as a model system to quantitatively analyse the occupancy of its atomic channels. High-angle annular dark-field imaging in a scanning transmission electron microscope is employed, revealing the presence of Cs atoms within the channels. Through statistical analysis of atomic column intensities and comparison with a series of multislice simulations, we successfully pinpoint the three-dimensional positions of individual Cs atoms. Our findings indicate a non-uniform distribution of Cs atoms in the crystal. Importantly, by extracting both the crystal thickness and atomic positions from a single high-resolution micrograph, we effectively minimize the adverse effects of beam damage. This approach offers a promising pathway for accurately determining the three-dimensional distribution of dopant atoms in various porous materials, opening new possibilities for the study and application of these technologically important materials.<\/p>\n<\/div>\n<\/section>\n<\/div>\n[\/vc_column_text][image_with_animation image_url=“11314″ image_size=“full“ animation_type=“entrance“ animation=“None“ animation_movement_type=“transform_y“ hover_animation=“none“ alignment=“center“ border_radius=“none“ box_shadow=“none“ image_loading=“default“ max_width=“100%“ max_width_mobile=“default“][vc_column_text text_direction=“default“]a<\/b>\u00a0Image of the crystal from Minas Gerais, Brazil;\u00a0b<\/b>\u00a0Crystal structure of beryl, exemplary with a Cs atom (yellow) typically placed in the channel cavity (2a site with a diameter of 0.5\u2009nm) and Li on the narrow 2b site (diameter 0.28\u2009nm); top view and side view of the structure.[\/vc_column_text][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"
