Al3+ environments in nanostructured ZnAl2O4 and their effects on the luminescence properties
(Amer Scientific Publishers, 2008-11-01)
Single-phase zinc aluminate (ZnAl(2)O(4)) with the spinel structure was successfully obtained by the Pechini method at different calcining temperatures for 4 hours. The nanoparticles are highly crystalline with no impurities ...

Pigments are used in ceramics, cosmetics, inks, and other applications widely materials. To this must be single and easily reproducible. Moreover, the pigments obtained in the nanoscale are more stable, reproducible and ...
Ni particles generated in situ from spinel structures used in ethanol steam reforming reaction
(Elsevier, 2020-03)
The in situ generation of Ni particles from a spinel structure used in the ethanol steam reforming reaction was studied. A series of Ni1-xCuxAl2O4 (x=0, 0.01, 0.05, 0.1) catalysts precursors were synthesized by the citrate ...
