Diffusion of Quinine with Ethanol as a Co-Solvent in Supercritical CO2
Shevtsova, Valentina (MDPI, 2020)This study aims at contributing to quinine extraction using supercritical CO2 and ethanol as a co-solvent. The diffusion coefficients of quinine in supercritical CO2 are measured using the Taylor dispersion technique when ... -
Difusioa, Termodifusioa eta Soret koefizienteak kalkulatzeko erabiltzen diren teknika desberdinak

Digital Interferometry Applied to Thermogravitational Technique
Lapeira, Estela; Aristimuño, Patxi Xabier; Bou-Ali, M. Mounir (Springer, 2018)In this work, we have applied Optical Digital Interferometry approach to thermogravitational micro-column technique. By the new analysis, we examine the entire height of the micro-column and determine the complete concentration ... -
Investigation of diffusive and optical properties of vapour-air mixtures: The benefits of interferometry
Shevtsova, Valentina (Elsevier Ltd., 2021)While interferometry has been widely used for diffusion measurements in liquid mixtures, it was hardly applied so far to vapour-gas mixtures. The present work aims to bridge this gap. Using an improved Mach–Zehnder ... -
The Soret coefficients of the ternary system water/ethanol/triethylene glycol and its corresponding binary mixtures
Bou-Ali, M. Mounir; Lapeira, Estela; Shevtsova, Valentina (Springer, 2021)Thermodiffusion in ternary mixtures is considered prototypic for the Soret effect of truly multicomponent systems. We discuss ground-based measurements of the Soret coefficient along the binary borders of the Gibbs triangle ... -
Transport properties of the binary mixtures of the three organic liquids toluene, methanol, and cyclohexane
Lapeira, Estela; Bou-Ali, M. Mounir (AIP Publishing, 2017)We report on the measurements of diffusion (D), thermodiffusion (DT), and Soret (ST) coefficients in binary pairs of the ternary system toluene-methanol-cyclohexane using different instrumental techniques: microgravity ...
