  • SYNTHESIS AND THERMAL STUDIES OF SOME EPOXY SYSTEMS CURED WITH AROMATIC DIAMINES 
    Naila Khalid; Muhammad Saif Ullah, Khan; Humaira Masood, Siddiqui; Zareen Akhtar; Naseer Iqbal (HEJ Research Institute of Chemistry, University of Karachi, Karachi., 2011-08-20)
    Some aromatic diamines having flexible ether linkages with variable aliphatic and aromatic character were synthesized via Williamson’s method and used as curing agents in their solution phase and/or molten state for a ...
  • SYNTHESIS OF TRIMETHLOL MELAMINE TEXTILE FIXER 
    Khalid Pervez, Bhatti; Muhammad Zuber (HEJ Research Institute of Chemistry, University of Karachi, Karachi, 2011-08-20)
    The synthesis of Trimethylol Melamine (TMM) precondensate was carried out by the controlled reaction of formaldehyde with melamine, which belonging to class of partially methylolated thermosetting resins. The product was ...
  • THEORETICAL STUDIES ON MEMBRANE-BASED GAS SEPARATION USING COMPUTATIONAL FLUID DYNAMICS (CFD) OF MASS TRANSFER 
    Sohrabi, Mahmoud Reza; Azam Marjani; Sadegh Moradi; Mehran Davallo; Saeed Shirazian (HEJ Research Institute of Chemistry, University of Karachi, Karachi., 2011-08-20)
    A 2D mass transfer model was developed to study carbon dioxide removal by absorption in membrane contactors. The model predicts the steady state absorbent and carbon dioxide concentrations in the membrane by solving the ...
  • Voltammetry of Nitrobenzene at Bare and DODAC Coated Pt 
    INAM-UL-HAQUE; MUQADDAS TARIQ (HEJ Research Institute of Chemistry, University of Karachi, Karachi., 2011-08-20)
    The reductive electrochemistry of nitrobenzene at one concentration was examined 1:1 water-propanol mixture at bare and DODAC covered platinum semi-micro electrodes using cyclic voltammetry. Generally it is believed [1-9] ...
