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

Spitzbarth, B. (author)Nature has inspired countless researchers in their quest to understand the phenomena we observe and utilise their findings to develop new technologies. This becomes especially apparent in systems chemistry, which heavily draws inspiration from natural systems in its pursuit for the understanding and development of chemical reaction networks ...doctoral thesis 2024

Wan, Z. (author)Self-healing concrete has great potential to enhance the durability of concrete structures without significantly increasing the initial costs. Among the self-healing approaches, vascular self-healing cementitious composite is capable of supplying healing agents to the cracked region in a continuous way or multiple times. However, the use of...doctoral thesis 2023

Chaves Figueiredo, S. (author)Adding extra functionality to cementitious materials will enhance the capabilities of understanding the use of structures where they are used and at the same time increase its life span. The construction industry is one of the most important economic sectors in many countries. Therefore, efforts to improve its productivity can result in...doctoral thesis 2023

Binti Md Yunus, B. (author)Under service conditions and because of environmental and climate changes, the concrete is at risk due to crack-induced durability problems. The consequences can be even more pronounced when concrete is exposed to specifically aggressive environmental conditions. This has been portrayed by rapid deterioration of relatively young concrete...doctoral thesis 2023

Rossi, E. (author)Self-healing concrete has attracted increasing attention of researchers and industry over the last decades. Given the brittle nature and the relatively low tensile strength of concrete, the occurrence of cracks is an almost unavoidable phenomenon affecting (reinforced) concrete structures. Cracks allow harmful agents present in the environment...doctoral thesis 2022

Vermeer, C.M. (author)Polyhydroxyalkanoates (PHA) are a family of biopolymers produced intracellular<br/>by a range of different bacteria.PHA have attracted widespread attention as<br/>an environmental friendly replacement of fossil-based polymers, because they<br/>have thermoplastic and/or elastomeric properties, and are also biobased and<br/>biodegradable.Moreover,...doctoral thesis 2022

Fu, Y. (author)When high-temperature steels are loaded under under industrially relevant conditions not only creep (i.e. a time dependent strain increase even under nominally constant loading conditions) occurs, but also local damage is formed. At relatively short exposure times quasi-spherical micron-sized cavities form preferentially at the grain boundaries...doctoral thesis 2022

Fan, B. (author)This thesis describes the experimental development of new dynamic hydrogels based on reversible thiol conjugate additions. Redox-controlled hydrogels and self-healing injectable hydrogels have been achieved by introducing reversible thiol conjugate additions to crosslink polymers, leading to hydrogel formation. The overall objective in this...doctoral thesis 2021

Montano, V. (author)The work exposed in this thesis addresses two main scientific challenges in the field of intrinsic self-healing polymers that limit the translation of the academic research efforts into commercial products, namely: i) the implementation of the self-healing functionality in polymer commodities by minimal chemical modifications; and ii) the...doctoral thesis 2021

Krishnasamy, J. (author)Thermal Barrier Coating (TBC) systems are protective layers applied to critical structural components of gas turbines operating at high-temperature. A typical TBC system consists of three different layers, namely a ceramic Top Coat (TC), an active Thermally Grown Oxide (TGO) layer and a metallic Bond Coat (BC). The outer ceramic TC that protects...doctoral thesis 2020

Xu, S. (author)Porous asphalt, due to its advantages of noise reduction and water drainage, is widely used in the surface layer of the highway in the Netherlands. However, the porous structure makes it prone to ravelling, therefore more frequent maintenance and reconstruction than other asphalt mixtures The porous asphalt service life can be extended with self...doctoral thesis 2020

Lampaert, S.G.E. (author)The bearing and the seal are two commonly used tribological components since nearly all moving machinery relies on them for proper operation. Even a small improvement in these components can have a big impact on both the market and the environment. The two main problems of these components are wear and friction. In addition, seals suffer from...doctoral thesis 2020

Lyu, W. (author)When concrete is subjected to sustained load, it first deforms elastically and then continues to deform with time. The stress-induced time-dependent deformation is, by definition, creep. Creep plays an important role in view of the serviceability, durability and sometimes even the safety of concrete structures. Prediction of the long-term creep...doctoral thesis 2020

Fang, H. (author)Solid-state phase transformations in steels cover a broad range of aspects. The underlying physics behind these phase transformations usually include nucleation, diffusion, lattice reconstruction and interactions between solutes and grain boundaries and interfaces. These features and the fact that the events take place at high temperatures, in...doctoral thesis 2019

Versteylen, C.D. (author)Advances in self-healing creep steels are driven by the understanding of its mechanism. Previous work on self-healing creep metals has shown selective precipitation inside the creep cavities, which has a beneficial effect on the creep lifetime. This effect occurswhen a solute supersaturation exists at the creep temperature. In the case of self...doctoral thesis 2018

Boatemaa, L. (author)Alumina (Al2O3) is an attractive ceramic for engineering applications operating at elevated or high temperatures because of its good thermal and chemical resistance. It also maintains high strength and hardness at high temperatures. These desirable properties are due to the strong covalent and ionic bonds existing between its atoms.<br/>However,...doctoral thesis 2018

Ponnusami, S.A. (author)Research in the field of self-healing materials gained significant attention in the last decade owing to its promise of enhanced durability of the material components in engineering applications. Though the research has led to several successful demonstrations, extensive experimental tests will be required for a successful demonstration. Further...doctoral thesis 2018

Post, W. (author)Over the past decade, many different strategies were developed to introduce selfhealing properties in structural polymer composite materials. Although many of the investigated routes show promising results on an academic scale, the first commercially feasible self-healing structural polymer composite has yet to be developed. The main objective...doctoral thesis 2017
