    Adsorption Characteristics of Cu(II) and Pb(II) Ions onto Natural Manganese Ore from Aqueous Solution by Taihong Shi, Shiguo Jia, Ying Chen, Yinghong Wen, Changming Du, Zhuochao Wang, Rongling Qiu

    Published 2008-10-01
    “…The resulting isotherms could be described by the Langmuir relationship, with the adsorbent showing a higher affinity towards Pb(II) ions than Cu(II) ions. Thermodynamic analysis indicated that the adsorption process was endothermic and possibly chemical in nature with positive values of ΔH 0 . …”

    Two-Dimensional Nonlinear Propagation of Ion Acoustic Waves through KPB and KP Equations in Weakly Relativistic Plasmas by M. G. Hafez, M. R. Talukder, M. Hossain Ali

    Published 2016-01-01
    “…Two-dimensional three-component plasma system consisting of nonextensive electrons, positrons, and relativistic thermal ions is considered. The well-known Kadomtsev-Petviashvili-Burgers and Kadomtsev-Petviashvili equations are derived to study the basic characteristics of small but finite amplitude ion acoustic waves of the plasmas by using the reductive perturbation method. …”
