to the coprecipitation system, it can greatly promote the ferrous iron oxidation rate and plays as role as the template of the secondary iron-based mineral, which can enhance the heavy metal... of A. ferrooxidans on iron-based secondary minerals can elevate metal immobilization efficiency correspondingly. Fig. 2 Variations of Fe(II) (a) and total iron (b) concentrations during coprecipitation......
during this process, which exhibits a potential risk of secondary pollution [10]. In recent years, there has been great interest in using iron-based materials that can substitute traditional ferrous... that this study can provide an excellent reference for seeking existing waste iron material or preparing new iron-based material behaving excellent reducibility. 2 Experimental section 2.1 Materials......
resource diminishes quickly. In contrast to lithium, sodium resource is abundant and sodium’s radius is closer to lithium within alkali metal [9–13]. Therefore, sodium and iron-based materials have... materials [J].Journal of the Electrochemical Society, 2009, 156: A993–A999. [18] ELLIS B L, MAKAHNOUK W R, MAKIMURA Y, TOGHILL K, NAZAR L F.

, a systematical first principles study on the electronic structure, chemical bonding, elastic and optical properties of the hexagonal phase Na2MgSn was done by using first-principles calculations based on DFT. 2 Calculation details The first principle calculations described here are based on DFT using a plan-wave expansion of the wave function [15,16]. The exchange correlation energy is calculated......
Peritectic reaction can be found in many materials, such as Fe- and Cu-alloys, YBa2Cu3Oy superconductors and Nd–Fe–B magnetic materials [1-7]. It involves one solid phase reaction with a liquid phase.... The constitutional undercooling improves the stability of the remelting interface. Based on the above analysis, the remelting interface is more stable because of the constitutional undercooling in solid phase......
