A rigorous model of electron attachment in lanthanide atoms

Written by

Understanding the physical mechanism underlying negative ion formation in low-energy electron collisions with lanthanide atoms is of fundamental importance in physics and chemistry. It also has important implications for a wide range of applications, from catalysis to drug delivery and water purification. Unfortunately, the complexity of the interactions among electrons in lanthanides has for a long time made it virtually […]

Aromaticity in anions in fluorine-free ionic liquids

Written by

ILs composed of bis(trifluoromethyl sulfonyl)imide (TFSI) anion with different nitrogen-based aromatic and aliphatic cations – such as imidazolium, pyridinium, pyrrolidinium, piperidinium and quaternary ammonium derivatives – are widely tested in energy storage research. The quaternary ammonium cations and their derivatives, coupled with the TFSI anion, have good electrochemical stability at room temperature, but are thermally less stable than their quaternary […]
