Fabrication of Maghemite Nanoparticles with High Surface Area

Autor: Yulia Trushkina, Cheuk-Wai Tai, German Salazar-Alvarez

Publikováno v: Nanomaterials, Vol 9, Iss 7, p 1004 (2019)

Maghemite nanoparticles with high surface area were obtained from the dehydroxylation of lepidocrocite prismatic nanoparticles. The synthesis pathway from the precursor to the porous maghemite nanoparticles is inexpensive, simple and gives high surfa

Publikováno v: Journal of applied crystallography 55(6), 1613-1621 (2022). doi:10.1107/S1600576722010093

The field-induced ordering of concentrated ferrofluids based on spherical and cuboidal maghemite nanoparticles is studied using small-angle neutron scattering, revealing a qualitative effect of the faceted shape on the interparticle interactions as s

The physicochemical properties used in numerous advanced nanostructured devices are directly controlled by the oxidation states of their constituents. In this work we combine electron energy-loss spectroscopy, blind source separation, and computed to
