Fe@α-Fe2O3 core-shell nanowiresCoercivityExchange biasThe defect structure, δ-Fe 2 O 3 , was grown epitaxially with ultrafine, activated Al 2 Si 2 O 5 (OH) 4 . More uniform particle size and consistent structure result with this process than with auto-nucleation. The low ferrimagnetic...
Several nanophases have been prepared by vaporization-condensation in a solar image furnace : binary oxides such as s γ-Fe2O3, In2O3, SnO2, ZnO and ternary oxides such as Zr1xYxO2δ. The vapor-condensates have been characterized by X-ray diffraction and Transmission Electron Microscopy. ...

(VI)adsorption capacity of the delta-FeOOH-coated gamma-Fe2O3,determined to be 25.8 mg/g,is higher than that of pure gamma-Fe2O3(19.4 mg/g).The high stability and recovery capacity of the delta-FeOOH-coated gamma-Fe2O3 were verified from regeneration studies and XRD investigations....
Maghemite (gamma-Fe2O3) nanoparticles and the (Cu0.5Tl0.5) Ba2Ca2Cu3O10-delta (CuTl-1223) superconducting phase were prepared separately by sol-gel and solid-state reactions, respectively. gamma-Fe2O3 nanoparticles were added into the CuTl-1223 superconducting phase to get (gamma-Fe2O3)...
