Nuclear pasta, with nonspherical shapes, is expected near the base of the crust in neutron stars. Large-scale molecular dynamics simulations of pasta show long lived topological defects that could increase electron scattering and reduce both the thermal and electrical conductivities. We model a possible low-conductivity pasta layer by increasing an impurity parameter Q_{imp}. Predictions of lig...

The equivalent conductivity of molten salts containing more than two ion constituents will be discussed using the equivalent fractions (Äquivalentanteile). The ionic conductivities of the ion constituents follow from this equivalent conductivity and the transport numbers. The electrical transport phenomena are referred to the idealized ionic melt which is defined by the limiting values of the i...

A composite cathode based on redox-stable La0.2Sr0.8TiO(3+δ) (LSTO) can perform direct carbon dioxide electrolysis; however, the insufficient electro-catalytic activity limits the electrode performances and current efficiencies. In this work, catalytically active scandium is doped into LSTO to enhance the electro-catalytic activity for CO2 electrolysis. The structures, electronic conductivities...

In this report, the thermoelectric properties of a Bi0.8Sb1.2Te2.9 nanowire (NW) were in-situ studied as it was trimmed from 750 down to 490 and 285 nm in diameter by a focused ion beam. While electrical and thermal conductivities both indubitably decrease with the diameter reduction, the two physical properties clearly exhibit different diameter dependent behaviors. For 750 and 490 nm NWs, muc...

nanofluids are gaining much importance over the past decade due to their enhanced thermal conductivity, specific heat, cooling capacity, electrical conductivities. novel properties of nanofluids are yet to be explored to the highest potential applications. one of the prominent applications of nanofluids is in thermal conduction. the presence of nanoparticle in a fluid can enhance the thermal co...
