  • ANNEALING EFFECTS ON SURFACE MORPHOLOGY, THICKNESS AND CHEMICAL PHASES OF Sr-Cu-O THIN FILM DEPOSITED BY MOCVD 
    Afzal Khan; Carmen Jimenez; Deschanvres, Jean-luc (Peshawar: Materials Research Laboratory Department of Physics University of Peshawar, Pakistan, 2010-07-02)
    The annealing process for obtaining SrCu2O2 out of the as-deposited Sr-Cu-O films by MOCVD was studied. Whatever the deposition condition may be, the as-deposited films are always composed of SrCO3 and CuO. As-deposited ...
  • KINETIC INVESTIGATION OF CHROMIUM (III) REMOVAL BY STRONG ACID EXCHANGER AMBERLYST-15(H+ ) 
    K. H. Shah; S. Mustafa; A. Naeem; M. Waseem; T. Ahmad (Peshawar: Materials Research Laboratory Department of Physics University of Peshawar, Pakistan, 2010-12-06)
    Cr(III) sorption on the strong acid exchanger Amberlyst-15(H+ ) is studied as a function of time and temperature using basic chromium sulphate [Cr4(SO4)5(OH)2] solution. Increase in temperature has a positive effect on ...
  • A NEW SUPERSTRUCTURE IN (LiXAg1-X) NbO3 (0.05 < X < 0.10) 
    H. U. Khan; I. M. Reaney; I. Sterianou (Peshawar: Materials Research Laboratory Department of Physics University of Peshawar, Pakistan, 2010-07-01)
    LixAg1-xNbO3 (0 ≤ x ≤ 0.10) compositions have been fabricated by the mixed oxide route to study the effect of Li on the host material, AgNbO3. The main X-ray diffraction (XRD) traces for ceramics with x < 0.10 were single ...
  • TEMPERATURE DEPENDENT STRUCTURAL AND ELECTRICAL ANALYSIS OF Mn-Zn NANO FERRITES 
    Humaira Anwar; Asghari Maqsood (Peshawar: Materials Research Laboratory Department of Physics University of Peshawar, Pakistan, 2010-08-03)
    Mn-Zn ferrite powders (Mn0.5Zn0.5Fe2O4) were prepared by the chemical co-precipitation method. The effect of annealing temperature on the crystalline phase formation and dielectric properties were investigated by X-ray ...
  • THERMAL ANALYSIS AND IMMOBILISATION OF SPENT ION EXCHANGE RESIN IN BOROSILICATE GLASS 
    N. H. Hamodi; K. A. Papadopoulou; Y. Iqbal (Peshawar: Materials Research Laboratory Department of Physics University of Peshawar, Pakistan, 2010-09-04)
    The underground disposal of waste arising from the nuclear industry needs constant evaluation in order to improve it through minimizing the volume and cost by reducing the amount of glass used without compromising the ...
  • THERMOGRAVIMETRIC STUDY OF POLYANILINE-DODECYLBENZENE SULFONIC ACID SALT 
    Salma Gul; Anwar-ul-Haq Ali Shah; Salma Bilal (Peshawar: Materials Research Laboratory Department of Physics University of Peshawar, Pakistan, 2010-07-03)
    Soluble polyaniline (PANI-DBSA) was synthesized by inverse emulsion polymerization. Dedecylbenzene sulfonic acid (DBSA) was selected as a surfactant because it also acts as a dopant. In this process a mixture of chloroform ...
