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...

In order to study the spallation phenomenon of titanium alloy under shock nanosecond laser, Neodymium-Yttrium-Aluminum Garnet laser was used carry out experiments on surface alloy. By observing and measuring morphology target material, forming factors changes different parameter settings, criteria were obtained. The results show that single variable method, change energy can affect shape variab...

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...
