Abstract: A method for producing crystals and for screening crystallization conditions of chemical materials on distinct metallic islands with specific functional groups by using multi-functional substrates comprising a plurality of self-assembled monolayers having at least two different functionalities, for preparing and screening conditions necessary to promote specific polymorphs of a crystal, and a means for testing and screening the more precise conditions suitable for achieving desired sizes or forms of a crystal.

Abstract: A device and process for crystallizing a compound using hydrodynamic cavitation comprising the steps of mixing at least one stream of a feed solution of such compound to be crystallized with at least one stream of an anti-solvent in a nucleating section via collision of the feed solution and the anti-solvent, passing the mixed streams at an elevated pressure through at least one local constriction of flow to create hydrodynamic cavitation thereby causing nucleation and the production of seed crystals, passing the fluid stream containing the seed crystals through an intermediate section to a crystal growth section, passing the fluid stream containing the seed crystals through the crystal growth section at an elevated pressure through at least one local constriction of flow to create hydrodynamic cavitation thereby causing further crystallization of the compound contained in the solution.

Abstract: Applying a strong static DC electric field to supersaturated aqueous glycine solutions resulted in the nucleation of the ? polymorph attributed to the electric-field induced orientation of the highly polar glycine molecules in large preexisting solute clusters, helping them organize into a crystalline structure. A method to induce crystallization and to prepare polymorphs and/or morphologies of materials by using a static electric field to cause nucleation and crystal growth to occur in a supersaturated solution in such a way as to obtain a crystal structure that would not normally appear without the use of the static electric field. Aqueous glycine solutions were prepared by combining solid glycine and water. Supersaturated solutions were generated by heating the tubes to 62-64° C. and holding them at that temperature in an ultrasonicator overnight. Once the glycine was completely dissolved, the solutions were slowly cooled to room temperature.
