We investigate the Seebeck effect in a three-dimensional Dirac electron system based on linear response theory and Luttinger’s gravitational potential. The coefficient S is defined by = L12/L11T, where T temperature, L11 L12 are longitudinal coefficients of charge current to electric field temperature gradient, respectively; conductivity thermoelectric conductivity. consider randomly-distribute...

An effective approach for reducing CO2 emissions from marine exhaust is adopting oxyfuel combustion technology. A series of B-site doped BaCo0.8B0.2O3−δ (B=Ce, Al, Fe, Cu) perovskites as novel oxygen carrier applications were prepared by the sol-gel method. The desorption characteristics and effects adsorption/desorption temperature, volume flow rate, partial pressures, adsorption time research...

We have reviewed our theoretical and experimental results of the low temperature superfluid response function ρs of high temperature superconductors (HTSC). In clean high-Tc materials the in-plane superfluid density ρ ab s varies linearly with temperature. The slope of this linear T term is found to scale approximately with 1/Tc which, according to the weak coupling BCS theory for a d-wave supe...

Substitution of copper by iron in the charge reservoir block YSr2Cu3O6+δ (YSCO) cuprate superconductor brings out an appealing insight on interplay between superconductivity and magnetism. In resulting FeSr2YCu2O7+δ (Fe-1212) materials, FeO1+δ layers CuO2 bi-layers are alternated along stacking direction, close analogy to RuSr2GdCu2O8 (Ru-1212) ferromagnetic superconductor. For FeSr2YCu2O7.57 c...

We investigate the effect of various symmetries of the superconducting order parameter ∆(ω) on the normalized tunneling conductance of SIN junctions by directly solving the real-axis Eliash-berg equations (EEs) for a half-filled infinite band, with the simplifying assumption µ * = 0. We analyze six different symmetries of the order parameter: s, d, s + id, s + d, extended s and anisotropic s, b...

Recently, a previous contributor showed how the delta-wye conversion may be applied to find the equivalent capacitance of five capacitors arranged in a bridge configuration. In fact, that contributor gave an algorithm for this purpose which showed that the equivalent capacitance depends upon all five capacitors. However, in this paper, we point out that there is a special case where the equival...
