WebUrea is often present in waste water but can be used in powering fuel cells and as an alternative oxidation substrate to water in an electrolyser. However, an insufficient mechanistic understanding and the lack of efficient catalysts for the urea oxidation reaction have hampered the development of such applications. Here we demonstrate that a nickel … Web1 de jan. de 2024 · Urea, a marker of uraemic retention in chronic kidney disease (CKD) and of adequacy of intradialytic solute removal, has traditionally been considered to be biologically inert. However, a number of recent experimental data suggest that urea is toxic at concentrations representative for CKD. First of all, at least five studies indicate that … Web27 de out. de 2024 · The Fe(urea) 6 3+ cation of compound 1 contains altogether 24 N–H bonds which form both intramolecular (within the cation, N–H⋯O bonds between the neighboring ligands) and intermolecular (between the cation ligand and peroxydisulfate anions) hydrogen bonds in the structure.
