The relationship of the effect of impurity on crystal growth and morphology, along with the internal stress and anomalous birefringence arising upon impurity trapping by a growing crystal, is considered. The NH4Cl-MnCl2-H2O-CONH3 model system and the

The nonequilibrium partition of components between a crystal and solution is mainly controlled by impurity adsorption on the surface of the growing crystal. The specificity of adsorption on the faces of various simple forms leads to the sectorial zon

The phase equilibrium and growth of mixed (Ba,Pb)(NO3)2 crystals in aqueous solutions were investigated. The microcrystallization method was adapted to systems with isomorphic components, where crystal composition deviates from the thermodynamic equi

The growth of NH4Cl crystals and their trapping of copper impurity in the NH4Cl-CuCl2-H2O-CONH3 quaternary system have been experimentally studied. The epitaxial adsorption of copper complexes on (100) faces leads to a sharp decrease in the growth ra

Curved-face growth of NaNO3 crystals under the action of the (NH4)2Mo2O7 impurity is studied experimentally and possible causes of face bending are analyzed. Selective impurity adsorption on the basal pinacoid results in growth of platelike crystals

This work supplements the adsorption model of 2D-isomorphism proposed earlier for the NH 4 Cl-CO(NH 2 ) 2 system and reveals the correspondence between the growth rates of the NH 4 Cl crystals in the presence of carbamide and the co-crystallization o

In the ammonium chloride crystallization region of the NH4Cl−CuCl2−H2O−CH3ON system, cocrystallization of the impurity with the main substance occurs by epitaxial adsorption of complexes of varying composition. In NH4Cl crystals, the Cu2+ impur

An isobutyl analog of phosphatidylcholine--isobutyl-2-(trimethylammonia)ethyl-phosphate (IPC)--was synthesized to accomplish the physical reconstitution of the zone-block model of biomembranes. X-ray analysis was used to study the IPC monohydrate (IP
