    • Heterogeneous esterification of free fatty acid to biodiesel 

      Siti Eda Eliana, Misi; Wan Nor Nadyaini, Wan Omar; NorAishah, Saidina Amin, Prof. Dr. (The Institution of Engineers, Malaysia, 2010-09)
      The potential of sulphated zirconia (SZ) as heterogeneous acid catalyst for esterification of free fatty acid (FFA) to biodiesel has been investigated. Experiments using oleic acid as a model compound preceded the ...

    • Optimisation of hydrolysis conditions for ethanol production from sorghum starch 

      Najiah, Nadir; Maizirwan, Mel, Dr.; Mohamed Ismail, Abdul Karim, Prof. Dr.; Rosli, Mohd Yunus, Prof. Dr. (The Institution of Engineers, Malaysia, 2010-09)
      The conversion of starch to sugar can be achieved by hydrolysis process. The two-step enzymatic hydrolysis of sweet sorghum was performed by commercially available α-amylase and glucoamylase. An optimisation study was ...

    • Seismic behaviour of thin/slender concrete walls with monolithic emulation base connections tested on shaking table 

      Nor Hayati, Abdul Hamid, Dr.; Linayage, Lionel; Mander, John B. (The Institution of Engineers, Malaysia, 2008-06)
      Two geometrically identical slender precast concrete walls with monolithic emulation base connections were constructed and tested under biaxial loading using two clover displacement control patterns on shaking table. ...

    • Simulation and optimisation of a SWRO system in cape town, South Africa 

      Lu, Hock Chee; Chong, Chien Hwa; Teo, Fang Yenn (The Institution of Engineers, Malaysia (IEM), 2021)
      A SWRO system was designed to fulfil 50% of the population water demand in Cape Town, South Africa, which can lead up to 383,353 m3/day in the next 15 years. The total dissolved solid (TDS) within the product (i.e. drinking ...
