Immobilization of Pb, Cu and Zn in contaminated soil The effectiveness of immobilization was evaluated by analyzing the leachable fraction of heavy metals from the ballmilled soil. When the milling time was 2 h, Pb, Cu, and Zn leaching concentrations decreased from 13.92 mg183;L1, 2.83 mg183;L1, and 114.42 mg183;L1 to 0.027 mg183;L1, 0.59 mg183;L1, and 0.16 mg183;L1, respectively; these values wer

  • Thermoelectric and mechanical properties of ZnSb/SiC

    218ensp;0183;ensp;Intermetallic compound ZnSb is a promising thermoelectric (TE) material with the advantages of low toxicity, abundance, and low cost; however, the relatively low figure of merit ZT and the brittleness of ZnSb limit its applications in TE devices. In this study, ZnSb/SiC nanocomposites were synthesized in order to improve both the TE and mechanical properties of ZnSb.
