Cobalt and manganese were selectively leached from LiNMC using an oxalic acid : choline chloride deep eutectic solvent, resulting in a nickel-enriched solid residue.

A series of highly unsymmetric heterobinuclear Mn/Co complexes is reported, in which an organometallic CpMn(CO)z fragment and a classical Werner-type cobalt(II) subunit are arranged in close proximity by means of a bridging pyrazolate. Two ligand scaffolds are employed that differ by the chelate size of the tripodal tetradentate {N41 binding site for cobalt. Molecular structures of three comple...

Several organs (lung, skin, thyroid, heart, bone marrow) are potential targets of cobalt (Co). Whereas there is no doubt that inhalation of Co alone may cause bronchial asthma, its role in the occurrence of hard metal disease is still controversial because most cases were reported in workers exposed not only to Co but also to other substances such as tungsten carbide, titanium carbide, iron, si...

This work suggests a method for obtaining heat-resistant protective coatings 08Kh17T stainless steel that can be used as interconnect material solid oxide fuel cells. The suggested approach is based on the layer-by-layer precipitation of nickel, cobalt, and manganese, followed by heat treatment in vacuum oxidizing atmosphere. XRD results show consist mixture metal oxides compounds with spinel s...

Processes for recycling lithium ion batteries (LIB), in particular complex chemistries such as those containing nickel-manganese-cobalt oxide (NMC) cathodes are hindered by tradeoffs between capital cost, process sustainability, and materials recovery. Most metal separations primary secondary production of critical elements rely on anion exchange chemistries. Herein, we explore the application ...

Nowadays, lithium-ion batteries (LIBs) are one of the most convenient, reliable, and promising power sources for portable electronics, tools, hybrid electric vehicles. The characteristics positive electrode (cathode active material, CAM) significantly contribute to battery’s functional properties. Applying various coatings is productive ways improve work batteries. there many methods depositing...

Manganese is an essential, but potentially toxic, trace metal in biological systems. Overexposure to manganese is known to cause neurological deficits in humans, but the pathways that lead to manganese toxicity are largely unknown. We have employed the bakers' yeast Saccharomyces cerevisiae as a model system to identify genes that contribute to manganese-related damage. In a genetic screen for ...
