3a. Dissolution and Growth Rate Analysis. The dissolution and growth results for all electric field intensities and polymorphs are shown in figure . As displayed in figure plot D, the application of electric field intensities less than 0.3 V/nm accelerates the dissolution of the 𝛼and 𝛽-glycine nanoparticles. Both 𝛼and 𝛽-glycine dissolve at a rate 3 times faster at 0.2 V/nm (~ -150 molecules/ns) than in the case of no field (~ -50 molecules/ns), allowing for a wide window of control over the dissolution rate. Unlike its counterparts, 𝛾 -glycine is only stabilized by the electric field, and dissolves at a decreasing rate with increasing field intensity. Remarkably, 𝛼 -, 𝛽 -, and 𝛾 -glycine nanocrystals can be forced to grow at rates upwards of 140 molecules/ns from an initially undersaturated solution for electric field intensities greater than 0.4 V/nm. This shows that the dissolution and growth rates of glycine nanocrystals in solution can be manipulated over two orders of magnitude through the application of the electric field, providing a significant control variable over the crystallization process dynamics. As such, crystal size distributions, which impact critical downstream processes such as milling and drying, are predicted to be controllable through manipulating the electric field intensity.
