UNLABELLED Many methylotrophic taxa harbor two distinct methanol dehydrogenase (MDH) systems for oxidizing methanol to formaldehyde: the well-studied calcium-dependent MxaFI type and the more recently discovered lanthanide-containing XoxF type. MxaFI has traditionally been accepted as the major functional MDH in bacteria that contain both enzymes. However, in this study, we present evidence tha...

In this paper we demonstrate that the effect of aromatic C--F substitution in ligands does not always abide by conventional wisdom for ligand design to enhance sensitisation for visible lanthanide emission, in contrast with NIR emission for which the same effect coupled with shell formation leads to unprecedented long luminescence lifetimes. We have chosen an imidodiphosphinate ligand, N-{P,P-d...

Abstract The chemical separation of zirconium from lanthanides by liquid–liquid extraction is challenging but critical for medical and technological applications. Using the example 89 Zr, we optimize liquid–liquid-extraction process means radiotracer technique. We produced Zr proton irradiation a metallic yttrium target at cyclotron. purification radionuclide was performed UTEVA resin. separate...

The application of quantum chemistry to systems containing atoms of the lanthanide (57La 71Lu) and/or actinide (90Th 103Lr) series is a considerable challenge and has been attempted only by a comparatively small number of researchers. Several complications, some of which will be described in the following, prevent standard quantum chemical approaches from being successful in this field in all r...

Single-crystal tubular products on the millimetre scale have been synthesized from water-soluble calixarene and phenanthroline in the presence of lanthanides by a hydrothermal method, in which the extended structures contain some 1D infinite channels.

Metallocene complexes of the Group 3 metals and lanthanides have been utilized for cyclization/silylation reactions of polyunsaturated organic substrates. Acyclic dienes, trienes, enynes, and dienynes can be selectively cyclized to provide fiveand six-membered rings in high yields.

Apotransferrin (apo Tf) in 0.1 M N-(2hydroxyethyl)piperazine-N2-ethanesulfanic acid at 25 ̊C and pH 7.4 has been titrated with acidic solution of Tb. The binding of Tb at the two specific metal-binding sites of transferrin was followed from the changes in the difference UV spectra at 245 nm. The molar absorptivity per binding site for Tb-Tf is 22,500 ± 1000 Mcm. To determine the Tb-Tf binding c...
