Continued humanitarian crises have caused the amount of forcibly displaced people to increase rapidly in recent years, creating an urgent need for constructing adequate sheltering to house the displaced. Governments and international organizations attempt to accommodate the growing demands by subsidizing and mass producing temporary transitional...

We have developed a fabrication methodology for label-free optical trapping of individual nanobeads and proteins in inverted-bowtie-shaped plasmonic gold nanopores. Arrays of these nanoapertures can be reliably produced using focused ion beam (FIB) milling with gap sizes of 10–20 nm, single-nanometer variation, and with a remarkable stability...

Kernel estimators are proposed for estimating the cumulative distribution functions and the probability density functions of several quantities of interest in a stereological oriented cylinder model. This oriented cylinder model was developed to represent anisotropic microstructural features in materials. The asymptotic properties of these...

The data-driven approach shows great potential for designing new materials with unprecedented properties by using machine learning and optimization. Recently, a data-driven framework was successfully applied to design a unit cell of metamaterial achieving super-compressibility, despite being built out of brittle base material. The key element of...

Bacterial biofilms are three-dimensional networks of cells entangled in a self-generated extracellular polymeric matrix composed of proteins, lipids, polysaccharides, and nucleic acids. Biofilms can establish themselves on virtually any accessible surface and lead to varying impacts ranging from infectious diseases to degradation of toxic...

Hot-dip galvanizing is a well-known process to increase the corrosion resistance of steel. As a by-product dross is formed in the Zn-bath. The dross particles are composed of Fe, Al and Zn in the form of Fe2Al5Znx and interact with the hardware that is submerged in the Zn-bath and eventually accumulate on the surface of the hardware. This...

Within the photovoltaic industry, a lot of research is done in order to minimize losses which are created during the conversion of solar light to electrical energy. In a crystalline silicon solar cell light has to pass through several layers before it enters the silicon wafer where the electron-hole pairs are generated. As one can imagine, if...

We present a new approach to estimate geometry parameters of glass fibers in glass fiber-reinforced polymers from simulated X-ray micro-computed tomography scans. Traditionally, these parameters are estimated using a multi-step procedure including image reconstruction, pre-processing, segmentation and analysis of features of interest. Each...

Wire and Arc based Additive Manufacturing (WAAM) processes are novel technologies that are seen as promising candidates for fabricating complex 3-Dimensional large scale components. These processes offer avenues to locally tailor metallurgy of the melt pool and thus produce functionally and compositionally graded components for improved...

The different phases in the life of archaeological objects can be described by artefact biography. This dissertation defines an updated version: artefact biography 2.0, and the life phases of Early Iron Age bronze studs from Oss-Zevenbergen, the Netherlands, are elaborated. Throughout the thesis, the research revolves around information value....

Research has shown the Circumferentially Notched Tensile (CNT) Specimen to potentially be a size-independent fracture toughness specimen. This research focusses on expanding the practical applicability of the CNT specimen as well as using it to perform fracture toughness tests on S690QT steel and simulated CGHAZ material in S690. <br/>Based on...

Understanding the stability of chemical interactions at the polymer/metal oxide interface under humid conditions is vital to understand the long-term durability of hybrid systems. Therefore, the interface of ultrathin PMMA films on native aluminum oxide, deposited by reactive adsorption, was studied. The characterization of the interface of the...

Despite observations of massive methane release and geohazards associated with gas hydrate instability in nature, as well as ductile flow accompanying hydrate dissociation in artificial polycrystalline methane hydrates in the laboratory, the destabilising mechanisms of gas hydrates under deformation and their grain-boundary structures have not...

Two-dimensional networks of quantum dots connected by atomic bonds have an electronic structure that is distinct from that of arrays of quantum dots coupled by ligand molecules. We prepared atomically coherent two-dimensional percolative networks of PbSe quantum dots connected via atomic bonds. Here, we show that photoexcitation leads to...

The safety of nuclear power plants is one of the major issues in nuclear materials research. In this context, this PhD thesis presents an original experimental investigation of melting behaviour of several refractory nuclear materials, whose phase diagrams are often still uncertain at temperatures exceeding 2500 K. The physicochemical properties...

Additional constriction of the arc in plasma arc welding has been investigated. By additionally constricting the arc, the power density at the work piece can be increased. If successful, it is hoped that this increase will approach values achieved in laser beam welding at a fraction of the costs of the latter. A survey of the available...

This paper focuses on the state-of-the-art research that has been done on fibre-reinforced polymer composites that are used to design a rapidly constructed building with an all-in-one skin. The past few hundred years, buildings have only been made from a small selection of materials. Mankind’s search for new building materials has produced many...

Due increasing energy use per capita and increasing world population, the world faces an energy-crisis. However, the energy required to solve it is abundantly available: solar energy. The technology to convert this energy to electricity, solar cell technology, is well-developed. The technical issue is how to manufacture solar cells at such a...

Auger recombination (AR) can be an important loss mechanism for optoelectronic devices, but it is typically not very efficient at low excitation densities. Here we show that in conductive quantum-dot solids, AR is the dominant charge carrier decay path even at excitation densities as low as 10?3 per quantum dot, and that AR becomes faster as the...
