Swart, Mik (author)Climate change is a pressing issue. Hydrogen aircraft are an excellent alternative to current kerosene aircraft, and appear to be the most viable long-term solution for net-zero flight. One of the main challenges for hydrogen aircraft is to sustain a low boil-off rate. This research explores the solution of active cooling of the LH2 mixture in...master thesis 2024

Liu, Q. (author), Ghodrat, S. (author), Jansen, K.M.B. (author)Conventional hinge actuators often face limitations including excessive weight, large size and unpleasant noise. Shape memory alloys (SMAs) offer a solution to address these issues due to their favorable characteristics, such as lightweight, high actuation force and small form factor. However, most existing SMA-based hinge actuators rely on...journal article 2024

Homan, S.J.T. (author), Aylar, K. (author), Jurjevic, A. (author), Scolari, M. (author), Urakawa, A. (author), Taheri, P. (author)When no hydrogen can reach the Pt catalyst in the anode for the hydrogen oxidation reaction (HOR) of an operating proton exchange membrane fuel cell (PEMFC), the anode potential increases and causes the cell potential to be reversed compared to normal operation conditions. During this reversal, the oxygen evolution reaction (OER) and carbon...journal article 2024

Shoja, Aydin (author), van der Neut, J.R. (author), Wapenaar, C.P.A. (author)Recently, the focus of reflection seismologists has shifted to applications where a high-resolution image of the subsurface is required. Least-Squares Reverse-Time Migration (LSRTM) is a common tool used to compute such images. Still, its high computational costs have led seismologists to use target-oriented LSRTM for imaging only a small target...journal article 2024

Huisman, Kees Theo (author), Abdellah, Mohamed H. (author), Alvarez Sosa, Damaris S. (author), Fernandes Simoes, Filipa R. (author), Blankert, Bastiaan (author), Vrouwenvelder, J.S. (author), Szekely, Gyorgy (author)Membrane modules for seawater desalination are becoming increasingly important for obtaining clean water with the rising global water scarcity. The productivity of membrane modules is compromised by biofouling on the membrane and feed spacer. Biofouling development can be mitigated by modification of the spacer or membrane surface. The...journal article 2024

Amladi, Amogh (author), Venkataraman, V. (author), Woudstra, T. (author), Aravind, P.V. (author)Energy storage is vital for the energy transition, enabling reliable power grids based on intermittent renewables. Reversible solid oxide cell (rSOC) technology is promising for seasonal energy storage. The novel finding from this work is that optimised air recirculation for rSOC in endothermic electrolyser mode leads to efficiency being...journal article 2024

Warns, Ruben (author)Innovation, akin to crafting a novel recipe, involves identifying problems, experimenting, testing, and sharing solutions. This study delves into "reuse innovations," which emphasize prolonging product usage before disposal. A prime exemplar is Home Carbonation Kits (HCKs), which can replace over 3000 single-use water bottles. Despite the...master thesis 2023
