    • Analysis of particle size and XRD in ZnO-based varistor 

      Noor Azira, Mohd Noor; Mohabattul Zaman B. S., NS Bukhari, Prof Madya; Muhammad Asri, Idris; Noor Mariamadzliza, Mohd Nan (Universiti Malaysia PerlisSchool of Materials Engineering & School of Environmental Engineering, 2010-06-09)
      ZnO varistors doped with Bi2O3, Sb2O3, CoO, MnO2 and Cr2O3 were prepared separately by two mixing processes: conventional and masterbatching mixed-oxide process method. After the mixing process, the ZnO-based varistor ...

    • Brief review on ZnO Synthesis methods, thin film & nanowire gas sensors 

      M., Kashif; Uda, Hashim, Prof. Dr. (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      ZnO nanowires are ideal building blocks for a wide range of nanoscale electronics, optoelectronics, and chemical sensing devices. The material properties change when the material is in nanowire form as compare to thin film ...

    • COD removal from semi-aerobic landfill leachate 

      Salwa, Mohd Zaini Makhtar; Naimah, Ibrahim; Mohammad Tamizi, Selimin (Universiti Teknologi Malaysia (UTM), 2009-06-02)
      Leachate are heavily polluted liquid which may contain large amount of chemical oxygen demand (COD), biological chemical demand (BOD), ammonia (NH3) and colour. This study was conducted to examine the percentage of COD ...

    • Removal of colour from landfill by solar photocatalytic 

      Salwa, Mohd Zaini Makhtar; Naimah, Ibrahim; Mohammad Tamizi, Selimin (Universiti Malaysia Sabah (UMS), 2009-08-12)
      This study was conducted to examine the percentage of colour removal using coagulation as pretreatment, followed by the effects of ZnO, pH, stirring time and solar photocatalytic as final treatment. The duration of ...

    • Study of ZnO films on SiO2/Si substrate by sol–gel spin coating method 

      Foo, Kai Loong; Uda, Hashim, Prof. Dr.; M., Kashif (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      ZnO films, type of the metal-oxide semiconductor promised a wide range of application, especially in optical and medical field. ZnO prepared from zinc acetate dehydrate as a precursor as a solvent exhibit high crytallinity ...

    • Study of ZnO thin film on silicon substrate by sol-gel spin coating method for bio-medical application 

      Foo, Kai Loong; Mohammad, Kashif; Uda, Hashim, Prof. Dr.; Syed Muhammad Usman, Ali Shah, Dr.; Willander, M., Prof. (Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
      Transparent semiconductor ZnO thin films deposited on p-Si (100) substrates with different solvent (Methanol and Ethanol) were obtained by sol-gel method. The coated ZnO films were annealed in furnace at 500°C for 2 hours. ...
