From the results, we made out that compounds 1–3 were binuclear structures, and 1D chain-like structures could be formed by hydrogen bonding. The thermal degradation data of the compounds and the three-dimentional infrared cumulative spectra of the gaseous decomposed products were obtained by TG/...
The hydrophobicity of ionic liquids is dependent on the alkyl chain length geometry of the cation and anion present in the structure, but having higher chains lengths of alkyl groups results in low values of density, more hydrophobicity, and high values of viscosity; these impacts may be differen...
Keywords: rare earths; neodymium magnets; solvent extraction; leaching; citric acid; acetic acid 1. Introduction Rare-earth elements (REEs) possess excellent physical and chemical properties, which is why they are used on a large scale in permanent magnets, lamp phosphors, NiMH batteries, catalysts...
