    Abstract: To understand the growth mechanism of Ag and Cu nanowires we have studied the effect of workfunction on the metal nanowire growth by XRD, SEM and Potentiostat. Under the same potential and overpotential, the metal with a smaller workfunction has a higher current density, i.e. current density for Ag is higher than of Cu nanowires. Likewise metals, t...

    Abstract: In an attempt to take advantage of industrial wastes, Iron slag was used to prepare some of glass samples in an attempt to re-use. The following chemical formula has considered in the preparation process. (25 + x) % slag + (75 - x) % (Na2B4O7.10H2O), where x has varied among different values. The rapid quenching method has used to prepare the glass... Show More

    Abstract: The biosorption of Cu (II), Zn (II) and Pb (II) ions from aqueous solution onto dried biomass (Urtica dioica leaves) is discussed in the present study. The effect of variation of contact time, adsorbent dose, pH, concentration of metal ions and temperature on biosorption of metal ion is studied. Maximum adsorption was recorded for initial metal ion... Show More
