Solvent-induced modifications of the morphology and solid-state properties of ibuprofen
The effect of crystallisation solvent on crystal morphology and mechanical properties of ibuprofen was studied. Intermolecular potentials were calculated to assess the relative growth rates of crystal faces of ibuprofen. Comparison of the predicted morphology with solution-"grown crystals clarified …

Investigation of Pharmaceutical Mass Transfer Phenomena Using Molecular Dynamics Simulations
… study included (1) the understanding of drug crystal dissolution at molecular level, (2) the elucidation of an unique mechanism for facile polymorphic transformation of crystalline drugs in solutions, and (3) the determination of drug-polymer interactions at water-crystal interface and the …

Modeling and simulation of the dissolution of a physical system with application to head-end operations in aqueous reprocessing
An electrochemically-based model of crystal dissolution is eveloped and implemented in a C++- and MPI-based parallel program in which (electro-)chemical reactions are formulated as Monte Carlo rules. The electrochemical model used assumes bonding in the solid to be a function of first nearest …

Effect of zinc substitution on the structure of calcium Fluoro-Alumino-Silicate glasses and glass-ceramics
… X-ray diffraction was conducted to identify the crystal phases formed. The density of zinc substituted glasses and glass-ceramics increased with increasing the zinc content. However, the oxygen density did not change significantly indicating a rather stable network that was not affected by zinc …
