    • The maximum number of exchange cycles in this study is two. With repeated exchange cycles, the average volume of the nanocrystals is invariant, whereas the structural imperfection (such as shown in Fig. 1 H) may accumulate.

    • This conclusion is based on a simplified diffusion picture in which the root mean square displacement of the diffusing particle is proportional to the square of the diffusion time. A general description of the ion exchange reaction requires the use of the Nernst-Planck equation, which does not have such a simple analytical relationship.

    • -10 s (32), whereas the reaction in solid phase is slower by many orders of magnitude; hence, not enough heat will build up in the nanocrystals to melt them.
