    • New silica supported HClO4 as an efficient catalysts for the estolide synthesis from oleic acid 

      Nor Asikin, Mohamad Nordin; Nadia Farhana; Aznira, Alias; Wan Nor Roslam, Wan Isahak; Jumat, Salimon; Mohd Ambar, Yarmo (Universiti Malaysia PerlisSchool of Materials Engineering & School of Environmental Engineering, 2010-06-09)
      The synthesis of estolides via condensation reaction of oleic acid were investigated using heterogenous and homogenous catalysts. The condensation reaction usually carried out by using of various acids catalysts, such as ...

    • Selective oxidation of glycerol over titania supported AuPd bimetallic catalysts 

      Ainol Hayah, Ahmad Nadzri; Noraini, Hamzah; Aznira, Alias; Jumat, Salimon; Mohd Ambar, Yarmo (Universiti Malaysia PerlisSchool of Materials Engineering & School of Environmental Engineering, 2010-06-09)
      Oxidation of glycerol to form various types of important short chain oxygenated derivatives became an important reaction to support biodiesel industries. In this study, a series of AuPd nanoparticles at different metal ...

    • Stabilization of magnetite nano iron oxide with a series of novel surfactants 

      Chin, Swee Yee; Chan, Samuel Hong Shen; Wan Zurina, Samad; Dipsikha; Panchanan, Pramanik; Nik Idris; Jumat, Salimon; Ambar, Yarmo (Universiti Malaysia PerlisSchool of Materials Engineering & School of Environmental Engineering, 2010-06-09)
      Oleic acid which is one of the palm oil derivatives is known to effectively stabilize dispersions of nanomagnetite in nonpolar solvent. Stabilization occurs because the carboxylic acid group covalently reacts with the ...
