Organic additives influence crystallization processes in a multitude of ways. In biomineralization,e.g.bone or shell, such additives play a crucial role in morphology, and in polymorph and size control. However, the specific interactions between the additives and the growing mineral are in general unknown. Here, a model of bone mineralization, namely the formation of apatite nanocrystals under the influence of poly(acrylic acid), is studied usingin situX-ray diffraction. Since the kinetics of these reactions are very temperature dependent, a new X-ray scattering reaction cell has been developed that allows very high temperature precision, with an r.m.s. variation during operation of ∼0.05 K. The performance of the cell and its use in studying the apatite/poly(acrylic acid) system are discussed. The apatite formation process proceedsviathe formation of an amorphous precursor which then crystallizes. It is found that poly(acrylic acid) retards crystallization and reduces the growth rate of the forming crystallites.

We have directly observed the <i>in situ</i> self-assembly kinetics of polyelectrolyte complex (PEC) micelles by synchrotron time-resolved small-angle X-ray scattering, equipped with a stopped-flow device that provides millisecond temporal resolution. This work has elucidated one general kinetic pathway for the process of PEC micelle formation, which provides useful physical insights for increasing our fundamental understanding of complexation and self-assembly dynamics driven by electrostatic interactions that occur on ultrafast timescales.
