Two new articles have been accepted for publication in the journals Membrane and Desalination, entitled Enhancing Palladium Recovery Rates in Industrial Solutions through Electrodialysis and Selective recovery of ions from copper-contaminated effluents using electrodialysis. The main person behind these articles is PhD-candidate Pauline Zimmermann who is now nearly ready to deliver her thesis. Palladium is a vital commodity …

Our new paper entitled A systematic non-equilibrium thermodynamics approach for assessing transport mechanisms in membrane distillation has just been published in Desalination. Membrane distillation (MD) is a promising technique for purifying volatile liquids at temperatures below their boiling points. Our study presents a systematic non-equilibrium thermodynamics (NET) approach for analysis of transport mechanisms in direct-contact …

Our research project entitled InterLab received an ERC Starting Grant. In the project,  we will bring new understanding and methods to predict transport of heat and mass across vapor-liquid interfaces. The project is really wonderful news for our group; it allows us to hire two new PhD-students, one Postdoc and one researcher and build two experimental …

Our new paper entitled Analytical treatment of ion-exchange permselectivity and transport number measurements for high accuracy has been published in the Journal of Membrane Science. In the article, we analyse electromotive force measurements of concentration cells using non-equilibrium thermodynamics, and determine the transference coefficients of ion-exchange membranes in aqueous KCl solutions. By taking advantage of the …

Me and Morten Hammer are currently visiting the Thermodynamics group of Joachim Gross at the University of Stuttgart to discuss common research projects.  The University of Stuttgart also has a large center of research on Porous media, called the “Collaborative Research Centre (SFB) 1313 Interface-Driven Multi-Field Processes in Porous Media. Flow, Transport and Deformation”. Next week, …

Our new paper entitled Revised Enskog theory for Mie fluids: Prediction of diffusion coefficients, thermal diffusion coefficients, viscosities and thermal conductivities has been published in the Journal of Chemical Physics. It was also selected as Editor’s pick. Since the 1920s, the Enskog solutions to the Boltzmann equation have provided a route to predicting the transport properties of …

Our new paper entitled Local equilibrium in liquid phase shock waves has been published in Physical Review E. In the article, we assess the assumption of local thermodynamic equilibrium in a shock wave by comparing local thermodynamic data generated with nonequilibrium molecular dynamics (NEMD) simulations with results from corresponding equilibrium simulations. The shock had a Mach number …

Our new paper entitled Free energy of critical droplets—from the binodal to the spinodal has been published in the Journal of Chemical Physics. Arguably, the main challenge of nucleation theory is to accurately evaluate the work of formation of a critical embryo in the new phase, which governs the nucleation rate. In Classical Nucleation Theory (CNT), this …

Our new paper entitled Classical density functional theory for interfacial properties of hydrogen, helium, deuterium, neon, and their mixtures has been published in The Journal of Chemical Physics. In the article, we present a classical density functional theory (DFT) for fluid mixtures that is based on a third-order thermodynamic perturbation theory of Feynman-Hibbs-corrected Mie potentials. The DFT …

Our new paper entitled Steady-State Two-Phase Flow of Compressible and Incompressible Fluids in a Capillary Tube of Varying Radius has just been published in Transport in Porous Media. In the article, we study immiscible two-phase flow of a compressible and an incompressible fluid inside a capillary tube of varying radius under steady-state conditions. The incompressible …
