The liquid-liquid extraction of neodymium(III) from succinate media (0.06 M) has been studied at pH 6.0 with the solution of 0.1 M of N-n-octylaniline in xylene when equilibrium is maintained for 5 min. The back-extraction of neodymium(III) has been performed by using 0.1 M HClO₄. The effect of various parameters, such as pH, equilibrium time, extractant concentration, stripping agents, organic...

The effects of the neodymium content on creep properties and microstructures 9Cr-3Co-3W-Nd-B steel were investigated. Neodymium had a mild effect rupture strength at contents up to 0.056 mass%. This suggested that compounds solid-dissolved minimal in uniformly creep-deformed parts after normalizing tempering heat treatment. On other hand, reduction area was improved by addition neodymium. Creep...

Monte Amiata is a recently extinct volcano that produced trachydacites and a few small olivine latite flows. The Amiata suite showed crustal strontium, neodymium, and lead isotopic signatures. Sr/Sr ratio values ranged from 0.712447 to 0.713068 and Nd/Nd ratios ranged from 0.512094 to 0.512203. Pb/Pb values ranged from 15.6694 to 16.2330 and Pb/Pb ratios ranged from 18.7125 to 19.0882. The oliv...

The southwestern tropical Pacific, part of a major pathway for waters feeding the Equatorial Undercurrent, is a region of important geochemical enrichment through land-ocean boundary exchange. Here we develop an original method based on the coupling between dynamical modeling and geochemical tracer data to identify regions of enrichment along the water pathways from the subtropics to the equato...

In 0.01 M 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (Hepes), pH 7.4 and room temperature, the binding of neodymium to N,N'-ethylenebis[2-(o-hydroxyphenolic)glycine] (EHPG), or N,N'-di(2-hydroxybenzyl)ethylenediamine-N,N' diacetic acid (HBED) had been studied from 210 to 330 nm by means of difference UV spectra. Two peaks at 240 and 292 nm appear in difference UV spectra after neodymium...

Cerium, neodymium and gadolinium contain double beta active isotopes. The most interesting are Nd and Gd (promising for 02 search), Ce (2 candidate with one of the highest Q2). The main problem of compounds containing lanthanide elements is their high radioactive contamination by uranium, radium, actinium and thorium. The new generation 2 experiments require development of methods for a de...

Harnessing ocean wave energy is an old challenge that has gained momentum in recent years. In this paper, we present the flow and electrical characterization of a prototype alternate liquid metal magnetohydrodynamic (MHD) generator at laboratory scale which potential to make use marine waves for its conversion into energy. The eutectic alloy Galinstan, used as working fluid, was driven oscillat...
