Effect of pseudohalide ligands on lanthanide/actinide group separation. Marian Borkowski. Los Alamos National Laboratory, Carlsbad, New Mexico 88220. The properties of the thiocyanate ligand and its applicability in actinide/lanthanide group separations has been well known since 1970. The solvent extraction of Y(III), Am(III), and selected lanthanides (La, Eu, Lu) by tri-n-butyl phosphate, TBP, have been tested with other pseudohalide ligands such as OCN-, N3-, NCS- and NCSe-. It was found that extraction of the NCS- and NCSe- complexes of Ln and An into the organic phase is very efficient but extraction of the OCN- and N3- complexes is very low. The partition of HNCS, HOCN, and HN3 acids between the organic (TBP) and the aqueous phase might be expected to serve, to a first approximation, as a model of the partition of the respective complexes. The distribution ratios of the corresponding pseudohalic acids have a reverse pattern compared to the partition coefficients of Ln and An-pseudohalide ...

The advances in computational actinide chemistry made in China are reviewed. Several areas relevant to chemistry of actinides in gas, liquid, and solid phases have been explored. However, we limit the scope to selected contributions in the chemistry of molecular actinide systems in gas and liquid phases. These studies may be classified into two categories: treatment of relativistic effects, which cover the development of two- and four-component Hamiltonians and the optimization of relativistic pseudopotentials, and the applications of theoretical methods in actinide chemistry. The applications include (1) the electronic structures of actinocene, noble gas complexes, An-C multiple bonding compounds, uranyl and its isoelectronic species, fluorides and oxides, molecular systems withmetal-metal bonding in their isolated forms (U-2, Pu-2) and in fullerene (U-2@C-60), and the excited states of actinide complexes; (2) chemical reactions, including oxidation, hydrolysis of UF6, ligand exchange, ...

A discussion of ph se diagrams of highly refractory oxides with oxides of lanthanides and actinides, as found in the literature, is presented. Included are certain generalizations concerning tetravalent actinide oxide systems containing one of the following: beryllium oxide, magn sium oxide, calcium oxide, aluminum o ide, zirconium oxide, silica, oxides of trivalent rare earth ele ents. Generalizations concerning oxides of trivalent rare earth elements are included. Systems with beryllium oxide are eutectic and analogous to systems with actinides. Also discussed are trivalent rare earth systems with aluminum oxides, ZrO2, S IO

Actinides are a series of chemical elements that form the basis of nuclear fission technology, finding applications in strategic areas such as power generation, space exploration, diagnostics and medical treatments, and also in some special glass. Thorium (Th) and Uranium (U) are the most abundant actinides in the Earths crust.. A deeper understanding of the properties of uranium and other actinides is necessary not only for their more efficient use in existing applications but also for proposing new applications. Several open questions remain, progress in this area usually limited in part by the difficulty in handling these materials safely.. The distribution of electrons in the outer orbital of the atoms that make up a given material is what defines whether they are electrical insulators, conductors or semiconductors, as well as whether they are hard or malleable. Other structural, electronic and magnetic properties are also defined by these valence electrons which may undergo electronic ...

The geometries and electronic structures of molecular ions featuring He atoms complexed to actinide cations are explored computationally using density functional and coupled cluster theories. A new record coordination number is established, as AcHe173+, ThHe174+, and PaHe174+ are all found to be true geometric minima, with the He atoms clearly located in the first shell around the actinide. Analysis of AcHen3+ (n=1-17) using the quantum theory of atoms in molecules (QTAIM) confirms these systems

The geometrical and electronic structures of Ln[(H2O)9]3+ and [Ln(BTP)3]3+, where Ln = Ce-Lu, have been evaluated at the density functional level of theory using three related exchange-correlation (xc-)functionals. The BHLYP xc-functional was found to be most accurate, and this, along with the B3LYP functional, was used as the basis for topological studies of the electron density via the quantum theory of atoms in molecules (QTAIM). This analysis revealed that, for both sets of complexes, bonding was almost identical across the Ln series and was dominated by ionic interactions. Geometrical and electronic structures of actinide (An = Am, Cm) analogues were evaluated, and [An(H2O)9]3+ + [Ln(BTP)3]3+ → [Ln(H2O)9]3+ + [An(BTP)3]3+ exchange reaction energies were evaluated, revealing Eu ↔ Am and Gd ↔ Cm reactions to favor the An species. Detailed QTAIM analysis of Eu, Gd, Am, and Cm complexes revealed increased covalent character in M-O and M-N bonds when M = An, with this increase being more ...

Three benzene-centred tripodal diglycolamide (Bz-T-DGA) ligands, where the diglycolamide (DGA) moieties are attached to a central benzene ring through ethylene spacers (LI), amide groups (LII) or ether linkages (LIII), were evaluated for their extraction behaviour towards trivalent actinide and lanthanide io

General understanding of intramolecular interactions engaged in molecular actinide species, in other words physical chemical mechanisms that drive the affinity of chelating ligands for actinide cations still needs to be deepened. In this field, X ray Absorption Spectroscopy has been extensively used as a structural and electronic metal cation probe. Combination with more traditional spectroscopic techniques as spectrophotometry is an ideal tool for the understanding of the chelation mechanism. Metallobiomolecules are considered as elaborate inorganic complexes with well-designed metal active sites. Although the various interaction processes between essential cations to biology and proteins are widely studied, focus on the actinide family is more seldom. Actinide impact to biological cycles has been motivated by risk assessments related to the wide use of nuclear fuel sources and industrial or military applications. In particular, the interactions of these cations with the biologically active ...

Recycling of actinides by their separation from spent nuclear fuel, followed by transmutation in fast neutron reactors of Generation IV, is considered the most promising strategy for nuclear waste management. Closing the fuel cycle and burning long-lived actinides allows optimizing the use of natural resources and minimizing the long-term hazard of high-level nuclear waste. Moreover, improving the safety and sustainability of nuclear power worldwide. This paper presents the activities striving to meet these challenges, carried out under the Euratom FP7 collaborative project SACSESS (Safety of Actinide Separation Processes). Emphasis is put on the safety issues of fuel reprocessing and waste storage. Two types of actinide separation processes, hydrometallurgical and pyrometallurgical, are considered, as well as related aspects of material studies, process modeling and the radiolytic stability of solvent extraction systems. Education and training of young researchers in nuclear chemistry is of ...

If you have a question about this talk, please contact Ian Farnan.. Phosphates are known to exhibit superior resistance to radiation damage, as evidenced by natural phosphate minerals that are minimally damaged despite containing alpha-emitting actinides for hundreds of millions of years. This study looks to investigate radiation damage in xenotime (YPO4) and zircon (ZrSiO4). Radiation damage occurs by two processes: the recoil of the heavy nucleus (70-100 keV) and the alpha particle itself (4.5-5.5 MeV), which loses energy primarily by ionizations but causes several hundred atomic displacements near the end of its path. Here we present results of Pu doping into xenotime, with insight into solid solubility and response to radiation damage compared to previous results for zircon. We also separate damage due to alpha particles from damage due to the heavy nucleus recoil and compare to Pu-doped studies.. For solid solubility and accelerated ageing studies, 239 and 238Pu-doped xenotime samples were ...

An understanding of the effect of cumulative radiation damage on the integrity of ceramic wasteforms for plutonium and minor actinide disposition is key to the scientific case for safe disposal. Alpha recoil due to the decay of actinide species leads to the amorphisation of the initially crystalline host matrix, with potentially deleterious consequences such as macroscopic volume swelling and reduced resistance to aqueous dissolution. For the purpose of laboratory studies the effect of radiation damage can be simulated by various accelerated methodologies. The incorporation of short-lived actinide isotopes accurately reproduces damage arising from both alpha-particle and the heavy recoil nucleus, but requires access to specialist facilities. In contrast, fast ion implantation of inactive model ceramics effectively simulates the heavy recoil nucleus, leading to amorphisation of the host crystal lattice over very short time-scales. Although the resulting materials are easily handled, quantitative ...

Research and development at INE are largely aimed at long term safety assessment of proposed deep geological repositories for high-level, heat producing nuclear waste (HAW) disposal. To ensure sound safety assessment, a molecular understanding of processes determinant in the fate of radionuclides, notably the actinides, and thermodynamic quantification is essential. Of central importance in such investigations is determination of actinide speciation (i.e., their chemical and physical form). X-ray spectroscopic methods have proved to be valuable tools for actinide speciation research. Investigations on non-fissile radioisotopes up to 106 times the legal exemption limit and fissile radioisotopes (Pu-239, U-235) up to 200mg, contained within two layers of protection, are possible.. The synchrotron-based activities at the INE-Beamline are embedded in INEs in-house research, thereby allowing a combination of analytical and instrumental methods, notably laser techniques and microscopic ...

It was found that slow desorption kinetics determine the cyclic working capacity for CO2 and H2O. Furthermore, four different adsorption sites are required to describe the observed complex adsorption behaviour of CO2 and H2O and their cyclic working capacity was determined based on many different carefully designed TGA and PBR breakthrough experiments. The sorption model includes two independent adsorption sites for H2O and CO2 (sites A and B resp.) and another site which can be occupied by both CO2 and H2O, where one component replaces the other (site C). A fourth site (site D) describes the general higher adsorption capacity of the sorbent if H2O and CO2 are fed together to the sorbent ...

19 August 2021 The Perez Art Museum Miami has announced its acquisition of thirteen new artworks, among them Hélio Oiticicas 1978 installation Penetrável Macaléia. This seminal work is both a culmination of many of Oiticicas early achievements and a tragic representation one of the last works conceived before his untimely death in 1980 at the age of 42.. Oiticica created his first Penetrável (Penetrable) in 1960, titled PN1, which consisted of a brightly painted, wooden structure with sliding doors that encouraged the viewer to enter and explore the space. This early work was grounded in the tenets of the Brazilian Neo-Concrete Art movement, and the series would ultimately become a major facet within Oiticicas oeuvre, one that he would return to time and again, shifting and morphing as his ideas developed and matured. The title of Penetrável Macaléia pays homage to musician and friend of Oiticica, Jards Macalé. As with many of his works, Oiticica created a fictional word for the title ...

On September 7, 2006, the car in which 4-year-old Lio Spinelli was riding with his mom, Sasha, was struck from behind by a lorry on the M2 motorway in Kent, England. The tragic accident took Sashas life and left Lio with critical brain and leg injuries. Lio had a severe growth plate fracture with extension of the fracture into the joint surface, explains Roger F. Widmann, MD, Chief of Pediatric Orthopedic Surgery. Because of his more pressing brain injuries, the orthopedic issues were not immediately addressed. He healed with closure of the growth plate in his knee, causing a progressive leg deformity. In addition, he had severe scarring inside his knee and the bone had healed in a position that wasnt optimal, limiting range of motion and making it difficult for him to walk or participate in any activities.. Surgeons overseas had recommended shortening Lios good leg and stopping the growth on the injured leg so that they would remain the same length. Lio and his father met with Dr. ...

The level density and γ-ray strength function (γSF) of 243Pu have been measured in the quasicontinuum using the Oslo method. Excited states in 243Pu were populated using the 242Pu(d,p) reaction. The level density closely follows the constant-temperature level density formula for excitation energies above the pairing gap. The γSF displays a double-humped resonance at low energy as also seen in previous investigations of actinide isotopes. The structure is interpreted as the scissors resonance and has a centroid of ω SR = 2.42(5) MeV and a total strength of B SR = 10.1(15) μ 2 N, which is in excellent agreement with sum-rule estimates. Lastly, the measured level density and γSF were used to calculate the 242Pu(n,γ) cross section in a neutron energy range for which there were previously no measured data. ...

Occasional dispatches from the front line of spiritual battle. A Catholic blog. Postings often conceived in the garden, at the playground or at the kitchen sink and hastily typed out far too late at night after putting the children to bed.

It is written that Hippocrates, father of modern medicine, once said: Let food be thy medicine and medicine be thy food. There is deep wisdom in this sentiment and many have suggested that diet is the key to atopic dermatitis. The truth, unfortunately, seems a little bit more complicated.. Despite heroic leaps in scientific understanding of the disease, the fundamental cause of atopic dermatitis (AD) remains obscure. That said, we certainly have some new ideas about what causes it, and have probably learned more in the past 10 years than in the past 10,000. Beyond a better understanding of the type of inflammation and immune system issues, we have discovered a great deal about the role of the skin barrier. In particular, a protein called filaggrin explains a lot about why patients might develop AD in the first place, but also-possibly-why they develop other types of allergies, including food allergies. [Dennin M] This protein, or more precisely the lack of it, leads to a condition that I ...

Zinc oxide-based sorbents, and processes for preparing and using them are provided, wherein the sorbents are preferably used to remove one or more reduced sulfur species from gas streams. The sorbents contain an active zinc component, optionally in combination with one or more promoter components and/or one or more substantially inert components. The active zinc component is a two phase material, consisting essentially of a zinc oxide (ZnO) phase and a zinc aluminate (ZnAl.sub.2 O.sub.4) phase. Each of the two phases is characterized by a relatively small crystallite size of
