Room temperature anodization of aluminum and the effect of the electrochemical cell in the formation of porous alumina films from acid and alkaline electrolytes

Alaba Oladeji, Araoyinbo; Azmi, Rahmat, Assoc. Prof. Dr.; Mohd Nazree, Derman, Dr.; Khairel Rafezi, Ahmad, Dr (VBRI Press, 2012)

Nanoporous alumina was produced by anodic oxidation of aluminum in both acidic and alkaline electrolytes. Previous reports indicate that nanoporous aluminais mainly produced from strongly acidic electrolytes, and with the ...
Using gibbs standard state free energy and a power regulating device to predict and control the fabrication of nanoporous alumina

Alaba Oladeji, Araoyinbo; Azmi, Rahmat, Prof.; Mohd Nazree, Derman, Dr.; Khairel Rafezi, Ahmad, Dr. (VBRI press, 2013-12)

The basic concept of Gibbs standard state free energy predicts a favorable condition for both room and high temperature fabrication of nanoporous alumina in phosphoric acid electrolyte. The anodization of aluminum foil in ...
