Abstract: Method for treating a drop of liquid, including: placing a drop (D) of liquid on a support surface (S); applying a time-varying electric field to the drop (D), thus moving a contact line of the drop (D) hence suppressing contact line pinning; and evaporating at least part of the liquid from the drop (D) during the application of the alternating field.

Abstract: Compositions, methods, and systems for controlling crystallization of an agent are generally described. In some embodiments, an agent is crystallized in the presence of polymer matrices, such as polymer particles. The polymer matrix may influence at least a portion of the crystallization process and/or the resulting composition. In some such embodiments, the polymer matrix allows one or more aspect of the process and/or composition to be controlled and/or altered. For instance, the polymer matrix may act as a crystallization promoter and/or acceptable carriers of the crystallized agent. In certain embodiments, the polymer matrix described herein, can be used with any agent regardless of its chemical and/or physical properties.
