The Front Cover picture illustrates the confinement of a metastable positronium, a bound state of an electron and a positron, in the micropores of a zeolite framework. The implementation of an atomic model that combines a Tao step potential with the crystallographic structure enables calculation of the distribution and lifetime of the positronium intrinsic to a given framework topology. More information can be found in the Full Paper by J. Pérez‐Ramírez and co‐workers on page 470 in Issue 5, 2017 (DOI: 10.1002/cphc.201601258).
