Arblaster, Thomas (author)Emerging in the domain of composite manufacturing, thermoplastic polymers can enable the reduction of process times, costs, and waste. In this study, lifecycle assessment (LCA) is used to evaluate a design for a carbon fibre-reinforced thermoplastic (CFRTP) wing rib, made from carbon fibre and polyetherketoneketone (CF/PEKK). The CF/PEKK rib is...master thesis 2023

Templated Synthesis of Diamond Nanopillar Arrays Using Porous Anodic Aluminium Oxide (AAO) MembranesZhang, C. (author), Liu, Z. (author), Li, Chun (author), Buijnsters, J.G. (author)Diamond nanostructures are mostly produced from bulk diamond (single- or polycrystalline) by using time-consuming and/or costly subtractive manufacturing methods. In this study, we report the bottom-up synthesis of ordered diamond nanopillar arrays by using porous anodic aluminium oxide (AAO). Commercial ultrathin AAO membranes were adopted as...journal article 2023

Li, Z. (author), Homborg, A.M. (author), Gonzalez Garcia, Y. (author), Visser, Peter (author), Soleimani, M. (author), Mol, J.M.C. (author)The influence of ageing under ambient conditions on the corrosion protective behaviour of a lithium-based conversion layer on AA2024-T3 is studied in this work. Conversion layers aged at ambient conditions for relatively short times (0 h and 4 h), show an initial high degree of corrosion inhibition but a much lower protectiveness after the...journal article 2023

Vidwans, Aditya (author), Trovalusci, Patrizia (author), Fantuzzi, Nicholas (author), Correia, J.A.F.O. (author)In steel structures, a lot of attention is paid to lightweight structures, i.e. reduction of dead load without compromising structural safety, integrity and performance. Thanks to modern steel aluminium foam sandwich panel manufacturing technology a new possibility became available for lightweight structural design. Assessment and...journal article 2023

van der Zalm, Joost (author)One of the main components used in superconducting quantum chips is the Josephson junction. Currently when fabricating Josephson junctions, the resistance uniformity at wafer-scale is not optimal. It is also known that an annealing process can alter the junction resistance and with it the qubit frequency. However, laser annealing has only shown...master thesis 2022

Spreij, Marlee (author)Refractories are widely used as lining material in the steelmaking industry. This class of materials is known for its superior creep resistance. However, creep of refractory linings is a known phenomenon in refractory science. Therefore, knowledge on creep behaviour is critical for furnace lining life predictions and selection of materials. This...master thesis 2022
