, their sensitivity to pH and the simultaneous presence of several species. Therefore, this work aims to further identify process by the thermodynamic calculation of Ni(II)-Co(II)-C2O42-- NH3-NH4+-H2O system and to understand correlation between the maintenance of the predefined Ni/Co ratio and fibrous morphology. Based on the thermodynamic calculation and the improved experiments, the fibrous Ni-Co alloys......
