Oxygen diffusion and vacancy migration thermally-activated govern high-temperature magnetism in ceria Abstract: Several experimental works currently demonstrate that metallic nano-oxides and carbon nanomaterials expected to be diamagnets, in fact, behave as ferromagnets at room temperature. […]
Investigation on acid functionalization of double-walled carbon nanotubes of different lengths on the development of amperometric sensors Abstract: Double-walled carbon nanotubes (DWCNTs) of different length were submitted to acid functionalization and investigated as chemical modifiers on […]
