Introduction: Crystal Growth of Organic Materials

Crystal Growth of Organic Soft Materials in Template-controlling Systems

Crystallization phenomena of organic soft materials occurring in template-controlling systems such as emulsions, vesicles, micelles and air-water interfaces have been discussed by reviewing recent work. Long-chain molecular crystals and amino acids were chosen as the model substances of the organic soft materials which are key materials in food, pharmaceutical, nuetraceutical, cosmetic, and oth...

Kinetic Monte Carlo Simulations of Crystal Growth in Ferroelectric materials

We study the growth process of ferroelectric materials by kinetic Monte Carlo simulations. An ionic model with long-range Coulomb interactions is used to model the relaxor single crystals. The growth is characterized by thermodynamic processes involving adsorption and evaporation, with solid-on-solid restrictions. An algorithm is developed in order to simulate growth under such a model, for whi...

Bulk Crystal Growth and Characterization of Semiorganic Nonlinear Optical Materials

High quality bulk single crystals of novel NLO semiorganics : L-arginine tetrafluoroborate (L-AFB) and L-histidine tetrafluoroborate (L-HFB) measuring 78 × 50 × 35 mm have been successfully grown from solution by temperature lowering methods. Solubility curves of these materials have been determined in different solvents, such as water, ethanol and acetone to determine the most suitable solvent...

Growth of Organic Glycinium Trichloroacetate Crystal and Its Characterization

Simulation study of twisted crystal growth in organic thin films.

Many polymer and organic small-molecule thin films crystallize with microstructures that twist or curve in a regular manner as crystal growth proceeds. Here we present a phase-field model that energetically favors twisting of the three-dimensional crystalline orientation about and along particular axes, allowing morphologies such as banded spherulites, curved dendrites, and "s"- or "c"-shaped n...
