    • A brief review of layered rock salt cathode materials for lithium ion batteries 

      Tan, Tze Qing; Soo, Soon Peng; Azmi, Rahmat, Prof.; Shamsul Baharin,  Jamaludin, Prof. Dr.; Rozana Aina, Maulat Osman, Dr. ; Zul Azhar, Zahid Jamal, Dato Prof. Dr.; Mohd Sobri, Idris, Dr. (Trans Tech Publications, 2013)
      Nowadays, many researchers have been studying on the layered rock salt-type structure as cathode materials for the lithium ion batteries. LiCoO2 is the most commonly used cathode material but Co is costly and toxic. Thus, ...

    • Electrical properties of fresnoite Ba2TiSi2O8 using impedance spectroscopy 

      Rozana Aina, Maulat Osman, Dr. ; Mohd Sobri, Idris, Dr. (Trans Tech Publications, 2013)
      Fresnoite with composition Ba2TiSi2O8 (B2TS2) was first found in 1965, adopting a non-centrosymmetric structure. It also reported to crystallize in a tetragonal unit cell with a=8.52Å and c=5.210Å leading to some possible ...
