Solubility measurement of a metastable achiral crystal of sodium chlorate in solution growth

Plasmonic Manipulation-Controlled Chiral Crystallization of Sodium Chlorate

“…For example, l -CPL irradiation efficiently traps d -clusters because of the difference of the refractive index, inducing the nucleation of d -crystal on/near the surface of the achiral metastable crystal. Then, because of the difference in solubility of achiral and chiral crystals, the d -crystal grows, while the achiral crystal dissolves, and finally, a polymorphic transition to the d -crystal is completed . This discussion well explains all the results shown in Table .…”

Radiolysis-Induced Crystallization of Sodium Chloride in Acetone by Electron Beam Irradiation

“…In fact, when we opened the liquid cell, we found that NaClO 3 crystals had formed as a result of increased local supersaturation at the contact point between the two solutions around the small Si chip (Supplementary Fig. S1), a similar result to that observed in antisolvent crystallization experiments (Niinomi et al, 2014). Therefore, in the observed region, the solution was not able to maintain a supersaturated state to permit the crystallization of NaClO 3 .…”

“…Using a liquid cell consisting of a pair of silicon (Si) chips with an amorphous silicon nitride (a-SiN) membrane as an observation window and an LC-TEM holder (Poseidon, Protochips, Inc., Morrisville, NC, USA) equipped with liquid injection ports, we began our crystallization experiments by mixing a saturated aqueous solution of NaClO 3 [NaClO 3 (aq)] with acetone. The solubility of NaClO 3 in acetone is much lower than that in water; consequently, mixing a small amount of NaClO 3 (aq) with a large quantity of acetone usually results in the crystallization of NaClO 3 (Niinomi et al, 2014). We filled the liquid cell of the TEM holder with NaClO 3 (aq) and filled the inner tube with acetone (Fig.…”

Plasmonic Manipulation of Sodium Chlorate Chiral Crystallization: Directed Chirality Transfer via Contact-Induced Polymorphic Transformation and Formation of Liquid Precursor

“…The control of crystallization from an aqueous solution, such as the nucleation, crystal growth, polymorphism, and crystalline shape, is highly required not only to obtain crystalline materials with the desired functionality, − effective pharmaceuticals, − and protein crystal analyzable by X-ray structural analysis , but also to explore the elementary processes of crystallization through the self-assembly of each building unit. Various approaches to controlling the crystallization have been attempted, such as, impurity addition, solvent change, ,, the application of external fields − and so on. Among them, light-induced crystallization has recently been intensively studied as a method to achieve a high controllability of crystallization. − The first demonstration of light-induced crystallization was demonstrated by Garetz et al in 1996 .…”
