      abstract     = {We performed operando Bragg coherent X-ray diffraction
                      imaging under CO oxidation,as well as oxidizing conditions
                      on a pre-characterized single PtRh nanoparticleand found
                      that this (111) oriented particle with truncated octahedral
                      shape is twinnedwith a Σ3 twin boundary parallel to the
                      SrTiO3 (001) support, at the height of thenanoparticle
                      edges. We observed that the average strain at the twin
                      boundary is higherunder CO oxidation conditions compared to
                      pure CO or O2. In addition, we observedthat two new facets
                      were forming during the oxidizing/reducing cycles.
                      Furthermore,we found mixed edge/screw dislocations at the
                      twin boundary, but only where the{111} side facets meet.
                      Inducing such dislocations changes the local strain and
                      theatomic structure of the nanoparticles, which may create
                      more active sites close to thenanoparticle edges.},
