“…Beyond its use in blasting, PETN is also used in pharmaceutical primary treatment of heart disease and diabetes (Icks et al 2007;Kristek 2000;Kristek et al 2007). However, as in other explosives, its physical properties are strongly related with internal factors such as crystallite particle size, crystal structure, dislocations, defects, and morphology Kunz 2000, 2001;Siviour et al 2004;Ter Horst et al 2001;Wang et al 2009). Properties can also be tailored by varying the external parameters such as temperature and supersaturation during growth of a crystal from the solution (Mezei et al 2007;van der Heijden and Bouma 2004).…”

A series of Zn ion-doped pentaerythritol tetranitrate (PETN) nanoislands in the form of thin films were prepared on Si substrates using spin coating. The effect of Zn concentrations on the sublimation energy was investigated by atomic force microscopy (AFM). The pure and Zn-doped nanoislands are imaged by AFM in contact mode at room temperature after annealing isothermally for a given time. The volume of the islands starts to decrease after annealing at 45 degrees C for pure PETN, whereas Zn-doped nanoislands start to decrease in height and volume after annealing at 55-58 degrees C. The minimum activation energy is found to be 29.7 Kcal/mol for 1,000 ppm Zn concentration. These studies are important for the long-term stabilization of PETN.

“…The physical properties of solvents play an important role in the solubility of the material and also in the crystal shape. Crystals grown from different solvents may yield different morphology [12][13][14]. Therefore, the selection of suitable solvents for the desired crystal morphology is a very important step before starting crystal growth.…”

A Different View of Solvent Effects in Crystallization

Solvents are widely used in crystallization, but their effects on the shape development of crystals are under debate. Here, we report a view on how solvents play their role by considering the viscosity of solvents. We synthesize silver particles in a mixture of alcohol and water. The viscosity of the solvent is changed by varying the volume ratio of alcohol in water. With the variation of viscosity, diverse morphologies of silver particles are synthesized. Small cubic crystals are formed at low viscosity, while hierarchical flower-like particles are formed at high viscosity. Two alcohols are employed, namely ethanol and propanol. No matter which alcohol is employed, the results are similar. Due to the limitation of mass transfer at high viscosity, the particles synthesized in such solvent are smaller and stabilized by the solvent. When the solution containing these particles are dropped onto metal substrates, these tiny particles firstly aggregate, which is followed by classic crystallization, forming flower-like hierarchical structures. These findings show the importance of the viscosity of solvents in shaping particles, which is underestimated previously.
