Paper in Crystal Growth & Design

The article of NIIC researches Bulavchenko A.I., Beketova D.I., Podlipskaya T.Yu, and Demidova M.G. is published in Crystal Growth & Design (IF 4.689)

Alexander I. Bulavchenko, Darya I. Beketova, Tatyana Yu. Podlipskaya, and Marina G. Demidova«Composition and Size of Reverse Micelles of Tergitol NP‑4 and Tergitol NP‑4 + AOT in N‑Decane during Evaporation Crystallization of KNO3»Cryst. Growth Des. 2014, 14, 3, 1142−1148DOI: 10.1021/cg401610m

Fourier transform-infrared spectroscopy, photon−correlation spectroscopy, and flame photometry were used to determine the rate of water evaporation, hydrodynamic diameter of micelles, and the content of water and K+ and Na+ ions in the studied microemulsions at different stages of evaporation crystallization of KNO3. In accordance with the Gibbs−Thomson (Kelvin) theory, high supersaturations suggest that in mixed micelles cores of smaller sizes are formed (up to 13 M). During crystallization, micelles with KNO3 solution coexist with KNO3 crystals. The function of micelles is to supply “building material” for their growth.

In accordance with the Gibbs−Thomson (Kelvin) theory, high supersaturations suggest that in mixed micelles cores of KNO3 of smaller sizes are formed.
