Magnetomigration of rare-earth ions in inhomogeneous magnetic fields
TL;DR: It has been showed that the low magnetic field gradients are sufficient to observe the magnetomigration effects of the ions in solution, and clearly establishes the behavior of magnetically different ions in initially homogeneous aqueous solutions exposed to magnetic fieldGradients.
Photostability of a highly luminescent europium beta-diketonate complex in imidazolium ionic liquids.
Peter Nockemann,Eva Beurer,Kris Driesen,Rik Van Deun,Kristof Van Hecke,Luc Van Meervelt,Koen Binnemans +6 more
TL;DR: A high quantum yield and an enhanced photostability was found for a europium(III) tetrakis(2-thenoyltrifluoroacetonate) complex after dissolving the complex in a weakly-coordinating imidazolium ionic liquid.
Thermochromism and switchable paramagnetism of cobalt(II) in thiocyanate ionic liquids
Stephen J. Osborne,Sil Wellens,Christopher P. Ward,Solveig Felton,Robert M. Bowman,Koen Binnemans,Małgorzata Swadźba-Kwaśny,H. Q. Nimal Gunaratne,Peter Nockemann +8 more
TL;DR: Temperature-dependent switching of paramagnetism of a cobalt(II) complex is observed in an ionic liquid solution, which enables mobility of thiocyanate anions by remaining mobile at low temperatures and acts as an anion reservoir.
Separation of rare-earth ions from ethylene glycol (+LiCl) solutions by non-aqueous solvent extraction with Cyanex 923
TL;DR: In this article, the separation of a mixture of rare earths by non-aqueous solvent extraction with two immiscible organic phases has been studied and the most performant extractant among the investigated acidic, basic and solvating extractants: Cyanex 272, Cyphos IL 101, Aliquat 336, bis(2-ethylhexyl)amine, trioctylphosphine oxide (TOPO) and Cyanex 923.

TL;DR: In this paper, the solvent-dependent spectroscopic and photophysical properties have been investigated by means of UV−vis spectrophotometry and steadystate and time-resolved fluorometry and are compared to those of the nonsymmetrically substituted 5-chloro-4,4,difluoro-3-phenylamino-8-(4-tolyl)-4-bora-3a,4a-diaza-sindacene (2).
