Ni-based catalysts generated by in situ reduction of MNiOx (M: La, Sr and Ce) were investigated in the methane Oxy-CO2 reforming reaction. The precursors and catalysts were characterized by X-ray diffraction, Thermoprogrammed Reduction and Oxidation

Bulk La(Fe,Si)13 materials received much attention because of their increasing magnetocaloric potential, low cost and T c tunable by Co or H substitution. However, the properties of these materials in nanometric dimensions have been investigated by f

LaCoO3 suffers spin crossover as a function of temperature, changing from low-spin state to intermediate-state and, at high temperatures, it also changes to a high-spin state. Nano-confinement of this material induces a long-range magnetic ordering,

Full Heusler alloys are well known to either crystallize in a cubic structure (Cu2MnAl-type), or present tetragonal distortions. Both structure types present interesting properties, like room temperature magnetic memory shape effect and/or remarkable
