Coupled mechanochemical theories for reacting systems with application to nanovoid nucleation and Li-ion batteries
… modeling. Furthermore, models based on the Kirkendall effect predict the process time, which is larger by orders of magnitude than in the experiment. A continuum-mechanics approach for nucleation and growth of a nanovoid in reacting NPs based on the Kirkendall effect is developed, which …

Surface Oxidation and Dissolution of Metal Nanocatalysts in Acid Medium
… the formation of Pt hollow nanoparticles by the Kirkendall effect is addressed, the role of vacancies is crucial in the removal of the non-noble core that yields to hollow nanoparticles. To investigate the reasons for the experimentally found enhanced ORR activity in porous/hollow nanoparticles, …

Sources of thermally generated vacancies in single-crystal and polycrystalline gold
… role in phenomena such as sintering, the Kirkendall effect, high temperature creep, polygonization and many other diffusion controlled processes. In spite of their importance very little is known about the fundamental properties of vacancy sources. For example, it is not known if a vacancy …

Mechanical behavior and environmental stability of GLAD-based Cu nanospring films
… nanospring layer height due to the diminishing effect of boundary conditions. Irrecoverable compression took place at high compressive stresses of the order of 110 MPa, which amounted to 50% strain and resulted in a permanent set of 0.6-1.1 µm within the nanospring layer, which was less than 15% …
