Multi-fidelity optimization methods promise a high-fidelity optimum at a cost only slightly greater than a low-fidelity optimization. This promise is seldom achieved in practice, due to the requirement that low- and high-fidelity models correlate well. In this article, we propose an efficient bi-fidelity shape optimization method for...

The growing group of health-conscious consumers drives the development and sales in the market of low- or non-alcoholic beverages. In particular, sales in alcohol-free beer (AFB) has drastically gained in recent years, giving the incentive to further advance alcohol-free products. This thesis comprises the development of a new technology to...

The separation of C8 aromatic hydrocarbons (e.g. xylenes) is one of the most important processes in the petrochemical industry. Current research efforts are focused on materials that can decrease the energy consumption and increase the efficiency of the separation process. Industrial processing of C8 aromatics typically considers adsorption in a...

Millions of people worldwide are exposed to excessive concentrations of fluoride (F<sup>−</sup>) from groundwater sources. Ca-Al-CO<sub>3</sub> layered double hydroxides (LDHs) have shown promising defluoridation efficiency; however, defluoridation by Ca-Al-CO<sub>3</sub> LDHs is highly pH sensitive. This study showed that simultaneous...

The continuous increase in the number of flights in the last decades caused a steepgrowth of aviation-related pollution to the point that the aviation sector is responsible for3% of the global greenhouse gas emissions. Regulators have been slow at catching up withthis problem, and stringent emission targets have been put in place only very...

The COVID-19 pandemic had a significant impact on the aviation industry with more than 60% reduction in the passenger traffic in the year 2020 compared to year 2019. The passenger traffic which is now expected to reach the 2019 level only around the year 2024 will still continue to grow but at a lower pace compared to the pre pandemic levels....

The Atlantic Meridional Overturning Circulation (AMOC) quantifies the strength of the northward surface transports and southward deeper transports in the Atlantic Ocean. In particular, as warm surface waters flow northward in the Atlantic they gradually cool on they journey releasing heat to the atmosphere. Then, in the subpolar and polar...

Batteries gained a lot of attention due to a raising demand for energy storage, as required for renewable energy generation systems, portable electronics and transport applications. For the development of new battery materials understanding of fundamental processes is essential, which often relies on the development of new characterisation...

Traffic congestion on motorways has become a common phenomenon across the world. Congestion on motorways is a major discomfort to road users and causes many problems such as reducing the capacity of the motorways, increasing travel times and fuel consumption leading to high economic and societal costs. Alleviating congestion and providing better...

Frugal innovation emphasizes the reduced use of resources and cutting of costs through the process of innovating around constraints. However, how innovating around constraints leads to profitable (value creation) businesses and local economic development impact (value capture) is still unclear. Early frugal innovation literature assumed that a...

Road safety is still a challenging issue. In 2020, 1.35 million people have died as a result of traffic accidents, where the number one cause of death for young adults between the age of 5 and 29 is car accidents. In an attempt to improve road safety, the automotive industry has developed numerous types of Advanced Driver Assistance Systems ...

We propose a microscopy scheme for the controlled modulation of the electron wave front that utilizes patterned electron mirrors. The ability to control the wave front of the electron finds many applications in electron microscopy, for instance in contrast enhancement techniques, beam mode conversion, low-dose imaging techniques such as quantum...

Alkali-activated materials (AAMs), as eco-friendly alternatives to Ordinary Portland cement (OPC), have attracted increasing attention of researchers in the past decades. Unlike cement, which requires calcination of limestone, AAMs can be made from industrial by-products, or even wastes, with the use of alkali-activator. The production of AAMs...

The entire research described in this thesis is part of the larger field of Systems Chemistry. This field of chemistry deals with the understanding of the complexity of biology by mimicking biochemical reaction networks with emergent properties attributed to the entire system. In particular, this research focuses on the design of artificial non...

Expanding cities across the world rely increasingly on the global food network, but should they? Population growth, urbanisation and climate change place pressure on this network, bringing its resilience into question. For decades urban agriculture has been discussed in popular media and academia as a potential solution to improve food security,...
