that copper porous materials with paraffin as porogen have lower porosity and permeability compared with materials using methylcellulose as porogen, due to the different pore-forming mechanisms... between adjacent powders, which further influence the sintering shrinkage. The porous materials using arborescent copper powders as matrix have lower porosity, smaller pore size and lower permeability......
Evolvement of permeability of ore granular media during heap leaching based on image analysis YANG Bao-hua(杨保华)1, 2, WU Ai-xiang(吴爱祥)3, JIANG Huai-chun(江怀春)4, CHEN Xue-song(陈学松)1 1. School..., and the permeability of each zone before and after leaching were also calculated with Carman-Kozeny equation. The permeability evolvement law was disclosed. The results indicate that before leaching......
Effect of Ce3+ on membrane permeability of Escherichia coli cell陈爱美,施庆珊,欧阳友生,陈仪本摘 要:This study aimed to delineate the antibacterial mechanism of rare-earth ion Ce 3+ to the target organism Escherichia coli cell, and the most important purpose was to identify its biological effect of increasing the E. coli cell membrane permeability. The antibacterial......
