Due to the ability of LiFePO4 (LFP) be charged with large currents, LFP batteries are widely used in household appliances and elect­ric vehicles, so recycling spent becomes an urgent need. First, they contain toxic components electrolyte that cannot buried landfills; secondly, cost lithium which contains electrode material continuously increases, therefore its return circulation is profitable e...

an efficient method for the friedel–crafts acylation of a wide range of aromatic compounds in good to excellent yields under solvent-free conditions, using iron zirconium phosphate (zpfe) was investigated. the catalyst is easy to prepare and shows interesting catalytic properties. the catalyst was characterized by some instrumental techniques such as xrd, icp-oes, sem and tem. a wide variety of...

BACKGROUND Recent studies in humans suggest that ferritin iron in soybeans has high bioavailability. However, direct evidence for this is lacking because the soybeans were intrinsically labeled; thus, iron bound to other ligands, such as phytate, was also labeled. OBJECTIVE The objectives of the study were to evaluate the absorption of iron from extrinsically labeled, purified ferritin (horse...
