Nanoscaled Nickel-Zinc-Iron Oxides of Spinell Type as Soft Magnetic Colloids and their Ferromagnetic Resonance Spectrum
Colloids made from ferrite nanoparticles are a good example of how the properties of materials change when scaled down to the nanometre scale: the continuous spectrum of magnetic spin wave excitations breaks up to a set of discrete absorption lines...

09/2006 | Radiochimica Acta, Oldenbourg WissenschaftsverlagStudy of the solubility of amorphous and crystalline uranium dioxide by combined spectroscopic methods
Colloid formation and solubility of U(IV) in acidic HClO4/NaClO4 solutions are investigated by coulometric titration...
