The formation and growth of maghemite (γ-Fe2O3) nanoparticles from ammonium iron(III) citrate solutions (C(6)O(7)H(6) · xFe(3+) · yNH(4)) in hydrothermal synthesis conditions have been studied by in situ total scattering. The local structure of the precursor in solution is similar to that of the crystalline coordination polymer [Fe(H(2)cit(H2O)](n), where corner-sharing [FeO(6)] octahedra are linked by citrate. As hydrothermal treatment of the solution is initiated, clusters of edge-sharing… 
Time-resolved in situ studies on the formation mechanism of iron oxide nanoparticles using combined fast-XANES and SAXS
The reaction of iron chlorides with an alkaline reagent is one of the most prominent methods for the synthesis of iron oxide nanoparticles. We studied the particle formation mechanism using
Structural Chemistry of Akdalaite, Al10O14(OH)2, the Isostructural Aluminum Analogue of Ferrihydrite

Formation and growth mechanism for niobium oxide nanoparticles: atomistic insight from in situ X-ray total scattering†
X-ray total scattering and Pair Distribution Function analysis is used to follow the formation and growth of niobium oxide nanoparticles and the presence of shear-planes in the structure appears highly dependent on nanoparticle size.
Impact of Solution Chemistry on Growth and Structural Features of Mo-Substituted Spinel Iron Oxides.
It is suggested that the synthetized compound is thermodynamically metastable, that is, kinetically trapped, and suggested to be a consequence of the tetrahedral site occupation by Mo ions.
The Molecular Mechanism of Iron(III) Oxide Nucleation.
It is shown that in the pren nucleation regime, thermodynamically stable solute species up to a few nanometers in size are observed, which meet the definition of prenucleation clusters, and nucleation then is not governed by a critical size, but rather by the dynamics of the clusters that are forming at the distinct nucleation stages.
Towards atomistic understanding of polymorphism in the solvothermal synthesis of ZrO2 nanoparticles.
Pair distribution function analysis unravels ZrO2 phase formation on the atomic scale and in this way provides a major step towards understanding polymorphism of ZRO2 beyond empirical approaches.
Role of Water During Crystallization of Amorphous Cobalt Phosphate Nanoparticles
