Abstract:
We report spontaneous chiral symmetry breaking in the evaporative crystallization of sodium chlorate by controlling the solution volume. We determine the critical volume, below which complete chiral symmetry breaking spontaneously occurs. This can be explained with regard to the rare probability of the simultaneous formation of multiple nuclei in a small volume, depletion attributed to the rapid consumption of surrounding sodium chlorate molecules upon crystal growth, and secondary nucleation. This study offers an important methodology for studying the chiral symmetry breaking behaviors in various chiral nanomaterials and organic molecules.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a...
