to be diffusion controlled. The activation energies of the anodic reaction for leaching system in the presence and absence of bacteria are 11.97 and 14.39 kJ/mol, respectively, indicating that leaching... on the surface of the sulfides can be oxidized by A. ferrooxidans after bio-electro-generative leaching for 24 h, and the transferred charge due to the bacterial oxidation is up to 17.86%, which......
microelectrophoresis apparatus is used to de-termine the surface Zeta-potential of flake graphite pure mineral, studythe affection of pulp pH value, seueral kinds of inorganic salt ions andanion surface activation agent (petroleum sodium sulfonate) on flakegraphite surface Zeta-potential,and explore the surface absorption charac-teristics of graphite.The floatation experiment of flake graphite pure mineral shows......

of this technique is the aging effect of the modifications on material surface. It is known that grafting technique is a traditional surface treatment method because the grafting agent could react with the fiber and then form stable chemical bonds [8]. Hence, the method combining grafting agent with plasma treatment should improve fiber surface properties effectively and, importantly, avoid the aging......
