Ding, Z. (author)Thermal barrier coatings (TBCs) are applied on the surface of metallic components of<br/>modern jet engines such as combustion chambers, blades and vanes, in order to increase the<br/>engine efficiency by allowing higher operating temperatures. However, during cooling from<br/>the operating temperature (i.e. 1000 °C) to room temperature high...doctoral thesis 2024

(author), Hauffman, Tom (author)In this work, the correlation between electrolyte transport properties and the variation of pigment volume concentration (PVC) in a series of organic coatings is explored. Using an odd random phase electrochemical impedance spectroscopy (ORP-EIS) approach, the diffusion of ions independent from water take-up is analysed. A higher PVC resulted...journal article 2024

Lin, B. (author), Heijman, Sebastiaan (author), Rietveld, L.C. (author)Ceramic nanofiltration (NF) is a promising alternative for direct surface water treatment, but is hampered for full-scale applications by fouling and a lack of eco-friendly cleaning regimes. In this work, an innovative reactive pre-coat layer, consisting of an iron oxychloride catalyst, was constructed on top of commercial ceramic NF...journal article 2024

Zamponi, R. (author), Avallone, F. (author), Ragni, D. (author), Schram, C. (author), van der Zwaag, S. (author)This paper elucidates the link between the near-wake development of a circular cylinder coated with a porous material in a low Mach-number flow and the related aerodynamic sound attenuation. It accomplishes this by formulating the cylinder flow-induced noise as a diffraction problem. The necessity for such an approach is driven by...journal article 2024

Li, Z. (author), Homborg, A.M. (author), Visser, Peter (author), Gonzalez Garcia, Y. (author), Mol, J.M.C. (author)In this work, the corrosion mechanism of AA2024-T3 covered by a lithium-based conversion layer is studied with high spatial and temporal resolution. Although the aluminium alloy surface is protected by a multi-layered conversion layer, areas around intermetallic phases (IMPs) represent weak spots due to an insufficient generation of a...journal article 2024

Magri, Etienne (author), Buhagiar, Vincent (author), Overend, M. (author)The design trend of most commercial and office buildings over the past three decades focused on attaining a façade design with the highest possible window to wall ratio. Whereas this approach appears to satisfy the aesthetic scope of developing buildings that look ‘modern and transparent’ to maximise on real estate value, the demand for...journal article 2023

Okonkwo, Bright O. (author), Jeong, Chaewon (author), Lee, Hyeon Bae (author), Jang, Changheui (author), Rahimi, E. (author), Davoodi, Ali (author)In this study, we developed and optimized a trivalent chromium coating electrodeposited on 304L stainless steel (SS) from a Cr-trivalent bath. The results reveal that the Cr coatings at all bath temperatures except for 80 °C showed clusters of polyhedral grains, however, the grain sizes decreased with an increase in bath temperature. Also,...journal article 2023

(author), Mastrobattista, E. (author), Amin Yavari, S. (author)Despite being the most widely used biomaterials in orthopedic surgery, metallic implants do not induce new bone growth because they are bioinert. Surface biofunctionalization of implants with immunomodulatory mediators is a recent approach to promote osteogenic factors that facilitate bone regeneration. Liposomes (Lip) can be used as a low-cost,...journal article 2023

(author), Terryn, H.A. (author)In this work, a new finite element modelling (FEM) approach is followed to model spatiotemporally resolved water uptake in organic coatings. To this aim, we start from a physical model, where not only Fickian diffusion of water is taken into account but also the adsorption/desorption reaction of water on the polymer matrix. Starting from a...journal article 2023

(author), Li, Xiaogang (author)Organic coatings are one of the most used and versatile technologies to mitigate corrosion of metals. However, organic coatings are susceptible to defects and damages that may not be easily detected. If not repaired timely, these defects may develop into major coating failures due to corrosion occurring in the damaged region, thereby limiting...journal article 2023
