      abstract     = {Core–shell particles with earth-abundant cores represent
                      an effective design strategy for improving the performance
                      of noble metal catalysts, while simultaneously reducing the
                      content of expensive noble metals1,2,3,4. However, the
                      structural and catalytic stabilities of these materials
                      often suffer during the harsh conditions encountered in
                      important reactions, such as the oxygen reduction reaction
                      (ORR)3,4,5. Here, we demonstrate that atomically thin Pt
                      shells stabilize titanium tungsten carbide cores, even at
                      highly oxidizing potentials. In situ, time-resolved
                      experiments showed how the Pt coating protects the normally
                      labile core against oxidation and dissolution, and detailed
                      microscopy studies revealed the dynamics of partially and
                      fully coated core–shell nanoparticles during potential
                      cycling. Particles with complete Pt coverage precisely
                      maintained their core–shell structure and atomic
                      composition during accelerated electrochemical ageing
                      studies consisting of over 10,000 potential cycles. The
                      exceptional durability of fully coated materials highlights
                      the potential of core–shell architectures using
                      earth-abundant transition metal carbide (TMC) and nitride
                      (TMN) cores for future catalytic applications.},
