The title compound, [Nd(OH)(SO(4))](n), was obtained hydro-thermally from an aqueous solution of neodymium nitrate, 1,2-propane-diamine and sulfuric acid. The structure features nona-coordinated neodymium with sulfate and hydroxide anions acting as bridging ligands. The OH group forms a weak O-H⋯O hydrogen bond with an O⋯O distance of 3.224 (5) Å.

The ready availability of very strong permanent magnets in the form of rare-earth magnetic alloys such as neodymium-iron-boron has lead to renewed interest in one of the oldest types of electric motors the homopolar motor. The ease with which a demonstration homopolar motor can now be built and operated when neodymium magnets are used is quite remarkable. In this paper two recent types of simpl...

This work obtained a sorbent based on humic acids (HA) isolated from oxidized brown coals of the Maikuben deposit. The study by IR spectroscopy showed presence various functional groups (OH-, COOH-) in sorbent, which can enter into ion-exchange reactions with metals. Humic have been tested as for neodymium. Neodymium sorption was carried out under static conditions nitrate solutions. It found t...

The dissolution rates of rare earth oxides and two types of rare earth containing functional materials into water, saline solution, and Gamble's fluid were measured in order to evaluate the biological effects of rare earth-containing functional materials. The tested materials were yttrium, lanthanum, cerium and neodymium oxides, and neodymium-boron-iron magnet alloy (NdBFe) and lanthanum-mish-m...

The development of the Chinese neodymium oxide electrolysis which replaced the chloride and fluoride electrolysis in the 1980s is described. Industrial data of the running neodymium electrolysis are given with scientific research references about the process. The new Chinese development of a horizontal electrode cell design is presented and concluded with a worldwide outlook.

Much information on ionic solvation in electrolyte solutions has been inferred from macroscopic thermodynamic and transport properties and from spectroscopy. These ion-water interactions can now be probed directly and unambiguously by neutron diffraction. Such measurements have been done with neodymium trichloride solutions in heavy water that are identical in every respect except the isotopic ...

A complex of neodymium(III) with 4-hydroxy-3[1-(4-nitrophenyl)-3-oxobutyl]-2H-1-benzopyran-2-one (acenocoumarol) was synthesized by mixing water solutions of neodymium(III) nitrate and the ligand (metal to ligand molar ratio of 1:3). The complex was characterized and identified by elemental analysis, conductivity, IR, 1H NMR and mass spectral data. DTA and TGA were applied to study the composit...

The title compound, neodymium sesquiselenide, is isotypic with the other known rare-earth metal(III) selenides M(2)Se(3) (M = La-Pr and Sm-Lu) with the cubic C-type structure. It adopts a cation-defective Th(3)P(4)-type arrangement with close to 8/9 of the unique neodymium-cation site occupied, leading to the composition Nd(2.667)Se(4) (Z = 4) or Nd(2)Se(3) (Z = 5.333), respectively. The Nd(3+)...

A global compilation of erosion rates and modeled dust fluxes shows that dust inputs can be a large fraction of total soil inputs, particularly when erosion is slow and soil residence time is therefore long. These observations suggest that dust-derived nutrients can be vital to montane ecosystems, even when nutrient supply from bedrock is substantial. We tested this hypothesis using neodymium i...
