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 ...
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 ...
