WebFeb 26, 2015 · Abstract. There is emerging evidence that growth of synthetic and natural phases occurs by the aggregation of prenucleation clusters, rather than classical atom-by-atom growth. Ferrihydrite, an iron oxyhydroxide mineral, is the common form of Fe 3+ in soils and is also in the ferritin protein. We isolated a 10 angstrom discrete iron-oxo cluster ...
