Electron and thermal transport properties, i.e., electrical conductivity, carrier concentration, Hall mobility, Seebeck coefficient, of heavily La- or Nb-doped SrTiO3 (STO) bulk single crystals were measured at high temperatures, (300–1050K) to clarify the influence doping upon thermoelectric performance STO. The temperature dependence mobility coefficient changed ∼750K in all samples because dominant mechanism for scattering with increasing from coupled by polar optical phonons acoustic...
Carrier concentration dependence of the thermoelectric figure merit, ZT SrTiO3 at high-temperature (1000 K) is clarified using heavily Nb-doped epitaxial films, which were grown on insulating (100)-oriented LaAlO3 single-crystalline substrates by a pulsed-laser deposition method. concentration, Hall mobility, Seebeck coefficient, and thermal conductivity films experimentally evaluated 1000 K with an aid theoretical analysis. increases Nb it reaches ∼0.37 (20% doped), largest value among...
To compare the intrinsic thermoelectric (TE) properties of heavily Nb-doped TiO2 to those SrTiO3 [S. Ohta et al., Appl. Phys. Lett. 87, 092108 (2005)], electrical conductivity (σ), carrier concentration (ne), Hall mobility (μHall), and Seebeck coefficient (S) (anatase) epitaxial films were measured at high temperatures (300–900K). The grown on (100)-face LaAlO3 single-crystalline substrates by a pulsed-laser deposition technique 800°C. effective mass (m*) anatase was ∼1m0, which is an order...
We investigated thermoelectric properties of 20-%-Nb-doped SrTiO3 at high-temperature (300-1000 K) using single-crystalline epitaxial film, polycrystalline film (average grain size ~200 nm) and ceramic ~20 μm) samples to clarify the effect boundaries on performance. Although carrier concentration Seebeck coefficient all showed no significant differences, Hall mobility was extremely small («10-1 cm2V-1s-1 300 as compared those sample (~3 cm2V-1s-1). However, it drastically increased with...
Various lithium-ion garnet-like oxides, Li7+X-Y(La3−XAX)(Zr2−YNbY)O12, (where A is an alkali earth metal) were prepared by solid-state reaction, and their conductivities lattice parameters determined AC impedance X-ray diffraction analysis. The La Zr sites in these materials simultaneously substituted, the extent of substitution was varied to optimize both parameter lithium content associated with highest possible conductivity. optimum at a constant be between 12.94 12.96 Å. Within this...
Abstract Background Little is known about the value of portal vein (PV) resection in distal cholangiocarcinoma. The aim this study was to evaluate clinical significance PV Methods Patients who underwent pancreatoduodenectomy (PD) for cholangiocarcinoma between 2001 and 2010 at one 31 hospitals Japan were reviewed retrospectively with special attention resection. Short- long-term outcomes evaluated. Results In interval, 453 consecutive patients PD, whom (6·8 per cent) had combined duration...
High-quality epitaxial films of layered cobaltite Na0.83CoO2 were successfully grown on (0001)-oriented α-Al2O3 substrate by reactive solid-phase epitaxy using CoO layer and NaHCO3 powder. First, the thermal oxidation film into Co3O4 occurs at a lower temperature (300−500 °C), then formed via lateral diffusion Na+ ions together with oxide layers.
Herein we demonstrate that Eu2+ substitution of SrTi0.8Nb0.2O3 is effective in reducing the thermal conductivity, with no reduction thermoelectric power factor (S2σ; S, Seebeck coefficient; σ, electrical conductivity). We prepared cubic (Sr,Eu)Ti0.8Nb0.2O3 crystals having same lattice parameter (a=0.395 nm) over whole composition range. Although dependence upon Eu content was observed for electron transport properties, including density states mass and carrier relaxation time...
Chemoradiotherapy (CRT) is currently performed for patients with esophageal squamous cell carcinoma (SCC). Some reports have revealed that who responded well to CRT had favorable outcomes, whereas poor responders conversely showed a worse prognosis. The aim of this study was identify molecular markers predicting sensitivity CRT.We reviewed 62 T(3-4), N-any, and M-any SCC treated definitive CRT. regimen comprised protracted 5-fluorouracil infusion 2-h cisplatinum combined radiation therapy (2...
Garnet-like oxides having the formula Li7+X-YLa3-XAXZr2-YNbYO12 (A = Sr or Ca) were synthesized using a solid-state reaction and their bulk grain boundary resistivities assessed by AC impedance measurements. A difference in resistivity was identified between Ca materials so boundaries examined electron probe microanalysis (EPMA). The attributed to core-shell structure of Sr-substituted samples. In contrast, Ca-substituted exhibited accumulations impurities at boundaries.

We explore the coannihilation region of constrained minimal supersymmetric standard model (CMSSM) being consistent with current experimental/observational results. The requirements from results are 125 GeV Higgs boson mass and relic abundances both dark matter light elements, especially lithium-7. put these on calculated values, and, thus, we obtain allowed region. Then give predictions to spectra (SUSY) particles, anomalous magnetic moment muon, branching fractions $B$-meson rare decays,...
