magnesium carbonate pre-nucleation clusters 30 (indicated by a steeper slope in the pre-nucleation stage, i.e. a less pro- nounced binding of calcium ions in the pre-nucleation

When ACC is precipitated in aqueous environments by direct mixing of solutions with concentrations of 0.1 M cal- cium and carbonate ions, no distinct proto-structure emerges. 24

Stable monodispersed amorphous calcium carbonate (ACC) nano- particles can be synthesized in ethanol media by a facile method, and crystallization of ACC is kinetically

Porous tablets of crystalline calcium carbonate were formed upon sintering of a precursor powder of amorphous calcium carbonate (ACC) under compressive stress (20 MPa) at relatively

Remarkably, the stabilizing effect of silica at high pH is strong enough to enable straightforward isolation of the clusters in large amounts. To that end, solutions

Calculated amounts of PS 20 (Aldrich) were added into the clear Ca(OHh solution and stirred vigorously. A volume of 350111 of precursor solution was dropped into each weil of a

% collagen fibers, and 10 wt% water; H "" 0.5 GPa).34 The lower H of the hybrid with 30 wt% ACC, compared to those hybrids with lower or higher ACC content, is

In the classical picture, nucleation is con- sidered to take place in a solution of ions that has become supersaturated, leading to the nucleation of the solid phase
