The effects of lanthanum and gadolinium on currents evoked by excitatory amino acids were studied in cultured rat hippocampal and cortical neurons, in freshly dissociated dorsal root ganglion neurons, and in human embryonic kidney 293 cells expressing the GluR6 kainate receptor subunit. In all of these cells, currents mediated by kainate-preferring receptors were antagonized by low micromolar c...

Lanthanides/actinides sorption speciation on minerals and oxides by means of time resolved laser fluorescence spectroscopy (TRLFS), extended X-ray absorption fine structure spectroscopy (EXAFS) and density functional theory (DFT) is reviewed in the field of nuclear disposal safety research. The theoretical aspects of the methods are concisely presented. Examples of recent research results of la...

The magnesian smectite hectorite is a corrosion product frequently detected in nuclear waste glass alteration experiments. The structural incorporation of a single trivalent lanthanide was previously demonstrated. Hectorite was presently synthesized, for the first time, in the presence of several lanthanides (La, Eu, Yb) following a multi-step synthesis protocol. The smallest-sized particles (n...

Upconverting materials have achieved great progress in recent years, however, it remains challenging for the mechanistic research on new upconversion strategy of lanthanides. Here, a novel and efficient strategy to realize photon upconversion from more lanthanides and fine control of lanthanide donor-acceptor interactions through using the interfacial energy transfer (IET) is reported. Unlike c...

Libraries of lanthanide complexes supported by nitrogen and oxygen containing ligands have been synthesised using a high-throughput approach. The complexes were employed in the ring-opening polymerisation of epsilon-caprolactone, in some cases giving polycaprolactone of controlled molecular weight and narrow polydispersity. The libraries, based on twenty-one ligands and eight lanthanide reagent...

Within international research in partitioning and transmutation (P&T), the separation of trivalent actinides (An(III)) from the chemical similar trivalent lanthanides (Ln(III)) is a main task that was comprehensively studied within the last two decades [1–3]. The investigated solvent extraction processes often follow the plutonium uranium reduction extraction (PUREX) process, in which uranium a...

Solid-state Ln-Bz compounds, where Ln stands for trivalent lanthanides and Bz is benzoate have been synthesized. Simultaneous thermogravimetric and differential thermal analysis in a CO2 atmosphere were used to study the thermal decomposition of these compounds.
