Abstract: Abstract Nanocrystalline Ni–Cu–Zn aluminate powders (Ni1-xCuxAl2O4, Cu1-xZnxAl2O4, and Zn1-xNixAl2O4) with different divalent ion concentrations (0 ≤ x ≤ 1) were successfully synthesized by the sol-gel auto combustion method using diethanolamine (DEA) as a novel fuel. The structural, morphological, and… read more here.
