Web"The Kirkendall effect refers to the formation of the so-called ‘Kirkendall voids’ caused by the difference in diffusion rates between two species. It is a classical phenomenon in … Web23 aug. 2024 · Macroporous magnetic Fe3O4 microparticles, which might act as both drug carriers and magnetocaloric media, were expected to have broad application prospects on magnetocaloric-responsively controlled drug release systems. A kind of macroporous magnetic Fe3O4 microparticle was prepared by an organic matter assisted open-cell …

WebKirkendall voids (KVs) were directly observed in the electrode interfaces of both Ni/Bi2Te2.7Se0.3 and Ni/Bi0.4Sb1.6Te3, providing thus the microscopic reason for the naked-eye cracks causing thermal failure. The growth of KVs of the as-investigated interfaces shows multi-stage behavior. Web30 apr. 2004 · Abstract. Hollow nanocrystals can be synthesized through a mechanism analogous to the Kirkendall Effect, in which pores form because of the difference in … navfac marianas commanding officer
