Abstract: Isothermal vapor–liquid–liquid equilibrium data were measured for the ethanol+water+diethyl carbonate (DEC) ternary system and the constituent binaries using static headspace gas chromatography (HSGC) at 353.15 and 363.15K. Multiple headspace extraction was used to calibrate the gas chromatograph. The activity coefficients were calculated using the Gibbs–Duhem equation and thermodynamic correlations. The thermodynamic consistency of the experimental vapor–liquid and vapor–liquid–liquid equilibrium data was verified. The experimental data were correlated using NRTL and UNIQUAC models, obtaining new UNIQUAC and NRTL interaction parameters for the VLE and VLLE. [Copyright &y& Elsevier]

One of the major obstacles to realizing spintronic devices such as MESO logic devices is the small signal magnitude used for magnetization readout, making it important to find materials with high spin-to-charge conversion efficiency. Although intermixing at the junction of two materials is a widely occurring phenomenon, its influence on material characterization and the estimation of spin-to-charge conversion efficiencies are easily neglected or underestimated. Here, we demonstrate all-electrical spin-to-charge conversion in Bi x Se 1-x nanodevices and show how the conversion efficiency can be overestimated by tens of times depending on the adjacent metal used as a contact. We attribute this to the intermixing-induced compositional change and the properties of a polycrystal that lead to drastic changes in resistivity and spin Hall angle. Strategies to improve the spin-to-charge conversion signal in similar structures for functional devices are discussed.
