      abstract     = {The stability of nanoparticles is a major challenge in
                      thermal and electrocatalysis. This is especially true for
                      core-shell nanoparticles where only a few monolayers of
                      noble metal protect the usually non-noble core material. In
                      this work, we utilize the practical nobility concept to
                      engineer stable core-shell nanoparticles with a
                      self-passivating core material. Specifically, tantalum
                      carbide as core material in combination with a 1–3
                      monolayer thick platinum shell exhibits exceptional
                      stability in aqueous media. The core-shell catalyst shows no
                      sign of structural changes after 10,000 degradation cycles
                      up to 1.0 VRHE. Due to the efficient passivation of tantalum
                      carbide at the solid/liquid interface, the dissolution
                      reduces by a factor of eight compared to bare Pt. Our
                      findings confirm that passivating core materials are highly
                      beneficial for the stabilization of core-shell nanomaterials
                      in aqueous media. They open up new ways for the rational
                      design of cost-efficient but stable non-noble core –
                      platinum shell nanoparticles where harsh, oxidizing
                      conditions are employed},
