    • Effect of Ca on the performance of Mg-Mn sacrificial anodes by electrochemical corrosion techniques 

      Shaiful Rizam, Shamsudin; C. I., Mahdi; Mohd Nazree, Derman; A. M. H., Firdaus; A. R., Daud; T., Loshniban (Universiti Malaysia PerlisSchool of Microelectronic Engineering and Institute of Nano Electronic Engineering (INEE), 2009-12-21)
      The aim of the study is to identify the effect of Ca in Mg-Mn alloy on electrochemical corrosion behaviour for development of high performance sacrificial anode. Mg alloys were fabricated by casting technique under an ...

    • Effect of small addition of aluminium on electrochemical corrosion behaviour of magnesium-calcium sacrificial anode in underground environment 

      Shaiful Rizam, Shamsudin; G., Sasirehka; A. M. H., Firdaus; C. I., Mahdi; D. M., Nazree; A. R., Daud; A. A., Azrem (PETRONAS, 2009-07-20)
      The effect of small addition of Al on the electrochemical performances was investigated by open circuit potential and Tafel Extrapolation method. The results show that open circuit potential reveals as-cast Mg containing ...

    • Effect of solution treatment on Mg galvanic anodes in CaSO4 – MG(OH)2 aqueous solution 

      A. M. H., Firdaus; Shaiful Rizam, Shamsudin; Shamsul Baharin, Jamaludin, Prof. Dr.; M. N., Derman; Mohd Fitri, Mohamad Wahid; C. I., Mahdi (PETRONAS, 2009-07-20)
      The effect of heat treatment on the Mg anode was investigated in CaSO4-Mg(OH)2 aqueous solution. The Mg sample was solutionised at 150oC, Pure and untreated Mg anode were also studied as a reference. Eoc and Tafel corrosion ...

    • Electrical properties of chitosan-ferredoxin film 

      Shantini, Devi; Irwana, Nainggolan, Dr.; Mohd Nazree, Derman, Dr.; Tulus Ikhsan, Nasution (American-Eurasian Network for Scientific Information (AENSI), 2013)
      In this study, chitosan was blended with ferredoxin to further improve the electrical properties of sensing film. Chitosan powder was dissolved in 2% of acetic acidand blended with ferredoxin. The mixture was subsequently ...

    • Electrode design and planar uniformity of anodically etched small area porous silicon 

      Ahmed, N. M.; Zaliman, Sauli, Prof. Madya; Uda, Hashim, Prof. Dr.; Zul Azhar, Zahid Jamal, Prof. Dr. (American Institute of Physics, 2009-06-01)
      Porous silicon layer microstructure is sensitive to many parameters, which need to be controlled during etching. These include not only anodization time, current density, applied potential and electrolyte composition but ...
