Kirkendall Effect: Nanofibers Comprising Yolk-Shell Sn@void@SnO/SnO₂and Hollow SnO/SnO₂and SnO₂Nanospheres via the Kirkendall Diffusion Effect and Their Electrochemical Properties (Small 36/2015)

Nanofibers with a unique structure comprising yolk–shell Sn@void@SnO/SnO2 nanospheres are generated by J. S. Cho and Y. C. Kang by applying the nanoscale Kirkendall diffusion process during conventional electrospinning. On page 4673, nanofibers prepared by applying this process exhibit superior electrochemical properties compared to those of porous-structured SnO2 nanofibers prepared by the conventional post-treatment process. The front cover image reveals the highly efficient lithium storage process of nanofibers composed of Sn@void@SnO/SnO2 yolk–shell nanospheres.
