  • Crystal structure of a new modification of lithium vanadate Li3(V,P)O4

    Yakovleva, E. V.   Yakubovich, O. V.   Dimitrova, O. V.  

    The crystal structure of a new phase of lithium vanadate, phosphate Li-3(V,P)O-4 obtained by hydrothermal synthesis in the Li3PO4-Li2CO3-V2O5-H2O system, is studied by X-ray diffraction (R = 0.0298): a = 6.3050(12), b = 10.921(2), and c = 4.9450(10); space group Pbn2(1), Z = 4, and rho(calc) = 2.543 g/cm(3). Specific crystal chemical features of the new compound are analyzed in comparison with related structures having three-dimensional tetrahedral frameworks that offer promise as anode materials in lithiumion batteries.

  • P–V–T equation of state of siderite to 33GPa and 1673K

    Litasov, Konstantin D.   Shatskiy, Anton   Gavryushkin, Pavel N.   Sharygin, Igor S.   Dorogokupets, Peter I.   Dymshits, Anna M.   Ohtani, Eiji   Higo, Yuji   Funakoshi, Kenichi  

    Pressure-volume-temperature relations have been measured to 33 GPa and 1673 K for natural siderite (Fe 0.95Mn 0.05CO 3) using synchrotron X-ray diffraction with a multianvil apparatus at the `SPring-8' facility. A least-squares fit of the room-temperature compression data to a third-order Birch-Murnaghan equation of state (EOS) yielded K0 = 120 +or- 1 GPa and K' = 3.57 +or- 0.09, with fixed V0 = 293.4 +or- 0.1 Aring 3. Further analysis of the high-temperature compression data yielded the temperature derivative of the bulk modulus (part KT/part T) P = -0.015 +or- 0.001 GPa/K and zero-pressure thermal expansion alpha = a0 + a1T with a0 = 3.57(9) times 10 -5 K -1 and a1 = 0.06(14) times 10 -8 K -2. The analysis of axial compressibility indicates that the c-axis is more compressible ( KTc = 59 +or- 1 GPa at K' = 2.7 +or- 0.1) than the a-axis ( KTa = 166 +or- 2 GPa at K' = 14.0 +or- 0.8). The present thermal EOS enables accurate calculation the density and thermodynamic properties of siderite to the deep mantle conditions. [All rights reserved Elsevier].

  • Role of Art v 3 in pollinosis of patients allergic to Pru p 3

    Sánchez-López, Jaime   Tordesillas, Leticia   Pascal, Mariona   Mu?oz-Cano, Rosa   Garrido, María   Rueda, Maria   Vilella, Ramón   Valero, Antonio   Díaz-Perales, Araceli   Picado, César   Bartra, Joan  

    Background: Food allergy caused by lipid transfer protein (LTP) from peach (Pru p 3) is frequently associated with sensitization to mugwort LTP (Art v 3). Although in vitro cross-reactivity is already well known, it has yet to be elucidated whether a pollen LTP can induce rhinitis.Objective: The aim of this study was to investigate whether mugwort LTP could elicit respiratory symptoms and whether a primary food LTP allergy could lead to a respiratory allergy.Methods: Patients with confirmed Pru p 3 allergy and control subjects were selected. Immediate responses to nasal allergen provocation tests (NAPTs) with Art v 3, Pru p 3, and mugwort were assessed by using the visual analog scale score, total nasal symptom score, and acoustic rhinometry. Tryptase and cysteinyl leukotriene (cysLT) levels were measured in nasal lavage fluid. Immunoblotting, ELISAs, and ELISA inhibition assays were also performed.Results: Fifteen patients and 9 control subjects were selected. NAPT results with Art v 3 and Pru p 3 showed significant changes in acoustic rhinometry, visual analog scale scores, total nasal symptom scores, and cysLT levels (P < .001). Tryptase levels were only increased in NAPTs with Pru p 3. NAPTs with mugwort were used in those patients who were only sensitized to Art v 3, with similar results (P < .05). No significant changes were detected in control subjects.Conclusion: The results demonstrated that a pollen LTP can elicit rhinitis in sensitized patients. Findings also suggest that a primary sensitization to Pru p 3 can lead to a respiratory allergy through cross-reactivity.

  • P–V–T equations of state of MgO and thermodynamics

    Peter I. Dorogokupets  

    A simplest equation within the framework of the Mie-Gr眉neisen–Einstein approach is considered. Pressure estimation values are presented that are derived by conventional arithmetic and algebraic calculations as a function of temperature and volume. The equation under consideration complies with the Mie-Gr眉neisen–Debye model at high temperature. Different versions of an equation of state (EoS) of MgO proposed by Speziale et al. (J Geophys Res 106B:515–528, 2001) as a pressure standard at high temperatures are subject to analyses. In the literature, at least four versions of Speziale et al. EoS of MgO are discussed; the discrepancy between them reaching a few GPa at T > 2,000 K and P > 100 GPa. Our analyses of these equations suggest that the volume dependence of the Debye temperature is accepted arbitrarily and does not agree with the definition of the Gr眉neisen parameter, γ = −(∂lnΘ/∂lnV) T . Pressure as a function of temperature and volume in the Mie-Gr眉neisen–Einstein approach or the Gao pressure calculator can be used to estimate true pressure at compression x = V/V 0 < 1 with the Speziale et al. EoS of MgO.

  • I–V characteristics of ZnO/Cu2O thin film n–i–p heterojunction

    Peiwei Lv   Weifeng Zheng   Limei Lin   Fuchuan Peng   Zhigao Huang   Fachun Lai  

    ZnO/Cu 2O thin film n-i-p heterojunctions were fabricated by magnetron sputtering. The microstructure, optical, and electrical properties of n-type (n-) ZnO, insulating (i-) ZnO, and p-type (p-) Cu 2O films deposited on glass substrates were characterized by X-Ray diffraction (XRD), spectrophotometer, and the van der Pauw method, respectively. XRD results show that the mean grain size of i-ZnO film is much larger than that of n-ZnO film. The optical band gap energies of n-ZnO, i-ZnO, and p-Cu 2O film are 3.27, 3.47, and 2.00 eV, respectively. The carrier concentration of n-ZnO film is two orders of magnitude larger than that of p-Cu 2O film. The current-voltage (I-V) characteristics of ZnO/Cu 2O thin film n-i-p heterojunctions with different i-ZnO film thicknesses were investigated. Results show that ZnO/Cu 2O n-i-p heterojunctions have well-defined rectifying behavior. All ideality factors of these n-i-p heterojunctions are larger than 2.0. The forward bias threshold voltage and ideality factor increase when i-ZnO layer thickness increases from 100 to 200 nm. An energy band diagram was proposed to analyze the I-V characteristics of these n-i-p heterojunctions. [All rights reserved Elsevier].
