Fixed bed arrangements find wide applications, particularly in reaction engineering, where they are employed as multi-tubular catalytic reactors for the transformation of reactants into desired products. The importance of such complicated reactors can be realized by their extensive applications as the process workhorse in various industries, e.g...

Rare earth elements (REEs), along with other metals, will play a pivotal role in the transition towards a low-carbon economy. Primary mining of REEs consists of multiple steps, is energy intensive and has an adverse environmental impact. Thus, the current scenario of “use and throw” of REEs after a single use in a product is untenable....

Quantum mechanics differs deeply from classical intuition and knowledge, sparking fundamental questions and radically new technology. Generating large entangled states between distant nodes of a quantum network will advance both domains. The nitrogen-vacancy (NV) centre in diamond is a promising building block for such a network.
However,...

Membrane separation is an energy efficient technology with a small physical footprint in which the membrane is the core of process. Membranes need to be further developed to be specifically applied in the field of gas separation. The most challenging target in designing membranes is to improve the permeation and selectivity, simultaneously. This...

Batteries have found widespread use, especially in mobile devices. With the inevitable energy transition the demand for batteries will rise further. Batteries for large-scale storage, transport applications and mobile devices all have different demands, requiring the development of a range of battery types for the storage of electrical energy....

Endovascular interventions include a variety of techniques, chiefly involving guidewires and catheters, that give access to the vascular system through small incisions. It is imperative to reach the place of interest quickly and safely. By considering the fact that the composition of guidewires and catheters differ (e.g., in material, diameter,...

Human brain consists of grey and white matter. Grey matter largely forms the
outer layer of the brain, and is responsible for decision making and functioning
of the human body. Complementary, the white matter (WM) contains the
communication pathways between the grey matter areas. Diffusion-weighted
magnetic resonance imaging ...

In this work, we investigate electronic and magnetic phenomena in thin films and heterostructures of transition metal oxides with strong spin–orbit coupling. Ultrathin films are prepared by pulsed laser deposition, a technique which enables layer-by-layer growth of complex materials on atomically flat crystal surfaces. The properties of these...

The necessity to process signals living in non-Euclidean domains, such as signals defined on the top of a graph, has led to the extension of signal processing techniques to the graph setting. Among different approaches, graph signal processing distinguishes itself by providing a Fourier analysis of these signals. Analogously to the Fourier...

This dissertation describes how to design dielectric pads that can be used to increase image quality in Magnetic Resonance Imaging, and how to accelerate image reconstruction times using a preconditioner.

Image quality is limited by the signal to noise ratio of a scan. This ratio is increased for higher static magnetic field strengths...

Solid State Lighting (SSL) develops towards small size, high lumen output, high working temperature, and multi-functional applications. These trends are more desirable in miniaturized LED applications such as retrofit G4 LED devices. Retrofit G4 LEDs were chosen in this work as a technical carrier due to the miniaturized size challenge and high...

Saltwater intrusion is a crucial issue in estuaries. The spread of salinity is described by the dispersion coefficient. A purely empirical equation which links the effective tidal average dispersion to the freshwater discharge was developed by Van der Burgh [1972]. Combining it with the salt balance equation, Savenije [1986] derived a one...

With the growth of global population, the big cities become increasingly crowded. It is not rare to see large crowds in public transportations and events with masses of visitors, such as music festivals and football matches. The question “How to deal with crowds” is receiving attention, both from academia and practical crowd management.
This...

Growing importance of hydrogels in various areas of human life has led to increasing need in controlling their properties, which is generally achieved by adjusting hydrogels shape and microstructure. Even though standard microfabrication and microstructuring techniques can be currently applied in hydrogel research, the variety of properties of...

Wheels are critical components of trains, and their conditions should be therefore monitored.Wheel defects change the wheel-rail contact and cause high impact forces thatare damaging for tracks and trains. Wheel defects can also cause unexpected failuresthat reduce the availability and reliability of the railway system. Several monitoring...

Artificial illumination has had profound and far-reaching impacts on the development, use, and perceptions of urban nights, and has brought with it many benefits. However, in recent years its adverse costs and effects – commonly referred to as light pollution – have emerged as a topic of concern. Nighttime lighting uses enormous amounts of...

The realization of interfaces between different transition metal oxides has heralded a new era of materials and physics research. Notably, it enabled a uniquely diverse set of coexisting physical properties to be combined with an ever-increasing degree of experimental control. The primary focus of this thesis is the celebrated interface between...
