Coexistence of Transient Liquid Droplets and Amorphous Solid Particles in Nonclassical Crystallization of Cerium Oxalate
Durelle M, Charton S, Gobeaux F, Chevallard C, Belloni L, Testard F, Trepout S, and Carriere D, The Journal of Physical Chemistry Letters (2022)
We found that solution crystallization of cerium oxalate involves two non-crystalline transients, namely solid amorphous nanoparticles, and reagent-rich liquid nanodrops.
Self-Confined Nucleation of Iron Oxide Nanoparticles in a
Nanostructured Amorphous Precursor
Baumgartner J, Ramamoorthy R K, Freitas P A, Neouze M-A, Bennet M, Faivre D, and Carriere D
Nano Letters (2020)
We have resolved at the nanoscale the formation of magnetite nanoparticles in solution, and compared to the classical nucleation / growth theories. We show that the transient amorphous, nanostructured network that forms in less than 6ms confines the crystallization reaction. These characterizations improve our understanding and mastery of the “non classical” crystallization mechanisms involved in biomineralization and numerous industrial processes.
Amorphous to Crystal Conversion as a Mechanism Governing the Structure of Luminescent YVO4:Eu Nanoparticles
Fleury B, Neouze M.-A., Guigner J.-M., Menguy N, Spalla O, Gacoin T, Carriere D
ACS Nano, (2014)
We have shown that crystalline YVO4:Eu nanoparticles synthesized in aqueous solution follow a non-classical nucleation mechanism. This originates from the formation of a transient nanostructured amorphous netwok, which templates the final structure of the crystalline nanoparticles.
