Bioleaching processes for extraction of Cu and Mo from molybdenite cons. are more environmentally friendly and consume less energy than conventional technologies, yet less economically efficient. One necessary step towards arriving at a cost-effective bioleaching process is using appropriate methodology to optimize pertinent factors in such processes. To this end, the present study employed Res...

The voltammetric characteristics of Mo (VI) oxinate at the mercury electrode, in the presence of tri-butylammonium perchlorate (tri-BAP) and piperidinium perchlorate (PP) + piperidine (P) as  two different types supporting electrolytes, have been studied in chloroform. With the both supporting electrolytes a two electron irreversible process for the reduction  of Mo (VI) oxinate was observe...

A series of carbonyl metal complexes with anions of functional «-amino acids has been pre­ pared: [M(CO),(L-histidinate)]' (M = Cr, Mo, W), M(CO),(L-histidinate) (M = Mn, Re), [Re(CO)3(NO)(L-histidinate)] + PF6-, M(CO)2(//3-allyl)(L-histidinate) (M = Mo, W), Mo(CO)2(NO)(L-histidinate), [Mo(CO)(NO)(^3-methalIyl)(L-histidinate)]PF6, Mo(CO)2(/73-methallyl)(L-histidineOMe)Cl, [M(CO)3(cysteinate)]2~...

In the present work, we aimed to focus on the identification and characterization of the heavy metal-tolerant plant species growing spontaneously at the tailings site of the Sarcheshmeh copper mine, south of Iran. Our aim was to find the plant species that were potentially useful for phytoextraction purposes. The concentrations of As, Cu, Mo, Ni, Zn, and Re were analyzed in soil as well as in t...

There is a considerable interest in low activation and high heat resistant materials for fusion applications. Tungsten (W) would fulfill these requirements for plasma facing components of future fusion power plants. A novel method developed by SNL to enhance the thermal and dimensional stability of W requires depositing materials such as Re and Mo as a thin coating on the surface of dendritic W...
