Special Issue Information

Dear Colleagues,

Interfacial phenomena are involved in almost every crystallization event. Crystal nucleation occurs as a result of competition between surface energies that resists the formation of a new interface and the driving force that induces the phase transition and subsequent crystal growth. The presence of low energy surfaces can reduce the free energy barrier and thereby facilitate nucleation. Thus, the affinity of the new precipitating phase for forming either in the bulk or at an interface that may be present (solid or gas) can greatly change the nucleation process and can also be used to control the location of crystal nucleation, the crystal morphology and/or its polymorphs. This special issue on “interfacial phenomena and crystallization” aims at gathering novel experimental and theoretical research on nucleation and growth of inorganic crystals / minerals, ice and hydrates both in bulk and in confinement: in droplets, porous media or microfluidic systems. This special issue will assemble the latest advances in different interdisciplinary fields in relation with this topic such as the fundamentals of nucleation and growth; controlled polymorphism, biomineralization, crystallization in emulsions and gas hydrate formation.

Accurate Calcium Oxalate Monohydrate (COM) solubility measurements are essential for elucidating the physiochemical mechanism behind the formation of kidney stones, nephrolithiasis. Yet the reported solubility values of COM in ultrapure water, arguably the simplest solvent relevant for nephrolithiasis, vary significantly depending on implemented method. To address this variation, we present an experimental study of the solubility of COM validated by a model based on the Debye–Hückel theory describing the solution chemistry and the complex formation. We also carefully monitor potential pseudopolymorphic/hydrate transitions during the solubility measurements with in-situ and ex-situ methods. Our results indicate that the solubility of COM in ultrapure water is a weak function of temperature. However, the measured solubility varies significantly in buffer solutions across physiologically relevant pH values at body temperature. The proposed model explains observed trends as a combined effect of ionic strength, protonation reactions, and soluble complex formation. Moreover, it predicts solubility of COM in buffer solutions remarkably well using our measurements in ultrapure water as input, demonstrating the consistency of presented approach. The presented study parleying experiments and modelling provides a solid stepping stone to extend the physiochemical understanding of nephrolithiasis to more realistic solutions laden with biological complexity.
