Charge localization increases chemical expansion in cerium-based oxides
(2012)In this work, we demonstrate the mechanism by which electronic charge localization increases the chemical expansion coefficient in two model systems, CeO 2-? and BaCeO 3-?. Using Density Functional Theory calculations, we ... -
Prismatic 2.0 Simulation software for scanning and high resolution transmission electron microscopy (STEM and HRTEM)
(2021)Scanning transmission electron microscopy (STEM), where a converged electron probe is scanned over a sample's surface and an imaging, diffraction, or spectroscopic signal is measured as a function of probe position, is an ... -
Reducing the chemical expansion coefficient in ceria by addition of zirconia
(2013)For thev first time, the role of isovalent Zr substitution in cerium oxide on the non-stoichiometry induced dilation (chemical expansion) was investigated. Chemical expansion was derived experimentally using HTXRD, ...
