The Daya Bay Reactor Neutrino Experiment has measured a nonzero value for the neutrino mixing angle ${\ensuremath{\theta}}_{13}$ with significance of 5.2 standard deviations. Antineutrinos from six 2.9 $\mathrm{G}{\mathrm{W}}_{\mathrm{th}}$ reactors were detected in antineutrino detectors deployed two near (flux-weighted baseline 470 m and 576 m) one far (1648 underground experimental halls. With $43\text{ }000\text{ }\text{ }\mathrm{ton}--\mathrm{G}{\mathrm{W}}_{\mathrm{th}}--\mathrm{day}$...
The design and development of a water-soluble heterocyclic ligand are believed to be an alternative way for improving the separation efficiency actinides from lanthanides. Herein, we designed synthesized novel hydrophilic multidentate ligand: disulfonated N,N′-diphenyl-2,9-diamide-1,10-phenanthroline (DS-Ph-DAPhen) with soft hard donor atoms, as masking agent in aqueous solutions Am(III) separation. combination N,N,N′,N′-tetraoctyldiglycolamide kerosene DS-Ph-DAPhen phases could separate...
Hybrid donor extractants are a promising class of compounds for the separation trivalent actinides and lanthanides. Here, we investigated series sterically loaded diphosphonate ligands based on bipyridine (BiPy-PO-iPr BiPy-PO-cHex) phenanthroline (Phen-PO-iPr Phen-PO-cHex). We studied their complex formation with nitrates f-elements in solvent extraction systems (Am Eu) homogeneous acetonitrile solutions (Nd, Eu, Lu). Phenanthroline demonstrated highest efficiency selectivity [SF(Am/Eu) up...
The fractionation of high-level radioactive waste from nuclear power plants simplifies the handling its components, and facilitates reduction radiotoxic effects on environment. search study new ligands for solvent extraction, as one methods in fractionation, remains a complex important research task. In this work, four pyridine diphosphonate were synthesized. These are part class N,O-donor extractants, which selective towards Am(III). separation factor SF(Am/Eu) best extractant reached...
Am3+/Cm3+ separation is an extremely hard but important task in nuclear waste treatment. In this study, Am and Cm complexes formed with a back-extraction agent N,N,N',N'-tetrakis[(6-carboxypyridin-2-yl)methyl]ethylene-diamine (H4TPAEN) its two derivatives hydrophilic substituents (methoxy morpholine groups) were investigated using the density functional theory (DFT). The optimized geometrical structures indicated that Am3+ cation matched better cavities of three studied ligands than Cm3+,...
Separation of trivalent actinides (An(iii)) and lanthanides (Ln(iii)) in spent nuclear fuel reprocessing is extremely challenging mainly owing to their similar chemical properties. Two amine-type reagents, tetrakis(2-pyridyl-methyl)-1,2-ethylenediamine (TPEN) its hydrophobic derivative N,N,N',N'-tetrakis((4-butoxypyridin-2-yl)methyl)-ethylenediamine (TBPEN), have been identified possess a selectivity for Am(iii) over Eu(iii). In this work, the structures, bonding nature, thermodynamic...
In recent years, there has been a trend to use synergistic systems of neutral and acidic extractants into single-solvent formulation achieve Ln3+/An3+ extraction separation via simplified processing schemes. this study, geometrical structures, bonding nature, thermodynamic stabilities series possible complexes Am3+ Eu3+ with two neutral-acid (CMPO-HDEHP CMPO-HEH[EHP]) were theoretically studied using scalar-relativistic density functional theory (DFT). It is found that hydrogen bonds between...
The treatment of nuclear spent fuels, especially the separation minor actinides, is an imperative task for healthy development industry. Up to now, it still remains a worldwide challenge separate trivalent An3+ from Ln3+ because their similar chemical properties. Therefore, investigating mechanism behind selective extraction by theoretical methods necessary. In this work, three phosphine oxide ligands with same side structures but different bridging frameworks, Ph2PyPO, Ph2BipyPO and...
Quantum chemical calculations reveal that weakening the affinity of N donor atoms may help to enhance ligand's Am<sup>3+</sup>/Cm<sup>3+</sup>separation ability.
Abstract We theoretically investigated the selective back-extraction towards Am(III) over Eu(III) and Cm(III) with two water-soluble 2,9-bis-triazolyl-1,10-phenanthroline derivatives BTrzPhen1 (with ethanol side chains) BTrz-Phen2 1,2-butanediol by density functional theory (DFT).

Abstract In this work, the “downward‐upward‐downward” stability trend of a series light lanthanide (Ln, from La to Gd) complexes with N,N,N′,N′‐tetrakis[(6‐carboxypyridin‐2‐yl)methyl] ethylene‐diamine (TPAEN) were theoretically investigated using density functional theory (DFT). TPSSh/SC‐ECP method which can better reproducing sample Eu‐TPAEN complex’ experimental geometrical structural data was selected investigate bonding nature, strength and thermodynamic properties these Ln‐complexes....
Linear alkyl benzene (LAB) is an attractive solvent for large scale liquid scintillator detectors due to its low toxicity, high flash point, and good compatibility with acrylic. Very optical purity required be used in detectors. We studied several LAB samples collected from two companies by measuring the light attenuation length, UV-Vis absorption spectrum, some other properties. Some of them have not transparency. Compositions these were then analyzed GC-MS dimensional GCxGC/MS. impurities,...
The charging behavior of PS (polystyrene) particles dispersed in nonpolar solvent containing surfactant AOT (sodium di-2-ethylhexylsulfosuccinate) was researched by phase angle light scattering (PALS). effects the concentration, particle concentration and size on zeta potential were analyzed systemically. results showed, at different concentrations (expressed volume fraction 10 − 5–10 3), that could be adjusted over a wide range 0.001–100 mM. An obvious difference revealed between high...
