Martinez Jimenez Fernan David1, Blankert Bastiaan1, Picioreanu Cristian1
1King Abdullah University of Science and Technology (KAUST), Water Desalination and Reuse Center (WDRC), Biological and Environmental Science and Engineering Division (BESE), Thuwal 23955-6900, Saudi Arabia

Modern composite membranes for reverse osmosis (RO) and nanofiltration (NF) have an ultrathin polyamide active layer (~100 nm) that performs the ion separation. Current theoretical models explain solute and water fluxes by computing concentration and potential gradients developed in one ... Read More

Numerical Simulation of the One-Way Mechanical-Electrochemical Coupling in Structural Supercapacitor

D. Peyrow Hedayati1, G. Kahlmeyer1, M. Kucher1, R. Böhm1
1Faculty of Engineering, Leipzig University of Applied Sciences, Leipzig, SN, Germany

Structural Supercapacitors (SSC) are an important group of Multifunctional Energy Storage Composites (MESC) and can potentially play a significant role in lightweight design of aerospace and automotive applications [1]. Therefore, it is important to build accurate models based on the ... Read More

Beyond the limits of mass transfer: How pillar electrodes influence electrochemical reactors

Michiel De rop1, Jonas Hereijgers1, Tom Breugelmans1
1University of Antwerp, Antwerp, Belgium

Electrochemistry is inherent a surface process, requiring the transport of reagents towards the electrode surface. In electrochemical reactors this typically results in mass transfer limitation problems, limiting the yield and efficiency of the reactor. While the academic community is ... Read More
