Ripepi, D. (author)In the last century, the indiscriminate use of fossil energy to power the industrial revolution and technological progress of humankind, has led to the depletion of limited natural resources and, most importantly, the emission and accumulation of alarming levels of pollutants and greenhouse gases (GHG) in the atmosphere. One of the major...doctoral thesis 2023

Blake, J.W. (author), Konderla, V. (author), Baumgartner, L.M. (author), Vermaas, D.A. (author), Padding, J.T. (author), Haverkort, J.W. (author)The use of gas diffusion electrodes that supply gaseous CO<sub>2</sub> directly to the catalyst layer has greatly improved the performance of electrochemical CO<sub>2</sub> conversion. However, reports of high current densities and Faradaic efficiencies primarily come from small lab scale electrolysers. Such electrolysers typically have a...journal article 2023

Hermans, Sebastiaan (author)In this thesis, a proof of concept was established for the use of a novel coupled QM-MD approach to modelling metallic (copper) electrode-electrolyte interfaces. SCC-DFTB calculations of the instantaneous electronic structure of a copper electrode were coupled to a classical MD simulation of an electrode-electrolyte interface. The applied QM-MD...master thesis 2022

Moree, Tijs (author)The most common serious heart rhythm disease is atrial fibrillation. It is not fatal on its own but does increase the risk of heart failures and strokes. There is little understanding about the mechanisms behind the disease, so more insight is desired. Using an array of electrodes, measurements are being performed of the electrical atrial...master thesis 2022
