Abstract Lithium battery cathodes contain lithium, cobalt, nickel, and manganese. Recycling of spent lithium batteries aims to recover these elements for re-use. Liberation cathode materials from other metals in the such as aluminium, copper, iron, is essential obtain a good leaching efficiency recovery valuable end-of-life batteries. This study investigates behaviour 18650 during H 2 SO 4 solu...

A method for the colorimetric estimation of manganese by reduction of the phosphomolybdicphosphotungstic acid phenol reagent has been described (Abul-Fadl, 1948). Cobalt was also found to give a similar colour reaction in the presence (but not in the absence) of amino-acids. Conversion of cobalt into the cobaltinitrite did not affect its response to this reaction. As methods for the estimation ...

Trace minerals are required for essentially all biochemical processes in the body. Many of these minerals are necessary for optimal growth, physiologic function, and productivity in animals. This paper focuses on 8 trace minerals: cobalt (Co), copper (Cu), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), and zinc (Zn). These trace minerals have been chosen because nutritio...

A novel one-pot laser-assisted approach is reported herein for the synthesis of ordered carbons with embedded cobalt nanoparticles. The process is based on a UV pulsed laser exposure of an ethanolic solution consisting of green carbon precursors, a structure directing agent and a cobalt salt. Very short irradiation times (5 to 30 min) are only required to polymerize and cross-link carbon precur...

Recent studies have demonstrated the potential of different nanocrystals synthesized in ferritin to act as light harvesters for high-efficiency solar cells. This study investigates the possibility of using these nanocrystals as alternative dyes for dye-sensitized solar cells. Four different dye-sensitized solar cells were successfully fabricated using iron, cobalt, manganese, and lead-sulfide n...

β-SiC-supported cobalt catalysts have been prepared from nitrate, acetate, chloride and citrate salts to study the dependence of Fischer–Tropsch synthesis (FTS) on the type of precursor. Com/SiC catalysts were synthetized by vacuum-assisted impregnation while N2 adsorption/desorption, XRD, TEM, TPR, O2 pulses and acid/base titrations were used as characterization techniques. FTS catalytic perfo...
