      abstract     = {Proper consideration of length-scales is critical for
                      elucidating active sites/phases in heterogeneous catalysis,
                      revealing chemical function of surfaces and identifying
                      fundamental steps of chemical reactions. Using the example
                      of ceria thin films deposited on the Cu(111) surface, we
                      demonstrate the benefits of multi length-scale experimental
                      framework for understanding chemical conversion.
                      Specifically, exploiting the tunable sampling and spatial
                      resolution of photoemission electron microscopy, we reveal
                      crystal defect mediated structures of inhomogeneous
                      copper–ceria mixed phase that grow during preparation of
                      ceria/Cu(111) model systems. The density of the microsized
                      structures is such that they are relevant to the chemistry,
                      but unlikely to be found during investigation at the
                      nanoscale or with atomic level investigations. Our findings
                      highlight the importance of accessing micro-scale when
                      considering chemical pathways over heteroepitaxially grown
                      model systems.},
