    • Microstructure characterization of Al/Calcined Dolomite Metal Matrix Composites 

      Banjuraizah, Johar; Azlin Fazlina, Osman; Alina Rahayu, Mohamed; N.A. Rejab; N.K. Su; M.S. Talib (Universiti Malaysia Perlis (UniMAP), 2007-06-09)
      Al/calcined dolomite metal-matrix composites (MMC) were fabricated and tested by varies the calcined dolomite content (10-30 wt%) and using unidirection compaction and sintering as consolidation method. Upon incorporation ...

    • Microstructure, Crystal structure and ionic conductivity of 3 mol % (Fe, Mn, Co, Zn) doped 8YSZ 

      Z. A., Ahmad; Banjuraizah, Johar; Tinesha, Selvaraj; ‪Khor, Shing Fhan; Kok, E. K. (EDP Sciences, 2016)
      Effect of 3 mol% of transition elements doped 8YSZ such as YSZZn, YSZFe, YSZCo and YSZMn on the ionic conductivity. SOFCs mostly operate at higher temperature. By substitute with dopants, it can reduce the operating ...
