The integration of luminescent nanoparticles into transparent polymer matrices opens the way to affordable, scalable and efficient luminescent solar concentrators. A key challenge in the fabrication is to prevent agglomeration of the nanoparticles as this will drastically reduce the performance due to scattering effects. The incompatibility of...

Additive manufacturing allows material structuring, supporting the fabrication of multiple-level structures or metamaterials. Through the lens of classical stress reduction, nature’s cellular solid structures feature stress-homogenizing nodal topologies. Avian long bones are an example. Research into the mechanics of open cell cellular solids...

Glass is one of the most remarkable building material in modern architecture. It has become more and more valued as a major construction material. It does not only provide continuous transparency but it can be applied as a main structural element due to its high load-bearing capacity. The structural system has already been realized in several...

Concentrated solar technologies have been successfully used to collect solar irradiance and transform it into useful heat for electricity generation. A problem in these systems is often that a mismatch between input and output is present due to variable solar irradiance and energy demand. To compensate for this mismatch storage is utilized to...

Water scarcity emphasizes the necessity of water recovery from saline sources, which are plentifully available. Nanofiltration (NF) is widely implemented in water reclamation treatment particularly in industrial field. However, the presence of silica hinders the possibility of obtaining a high recovery in a NF membrane system. In this work, the...

Fatigue cracks could occur in the material of offshore and marine structures that are cyclically loaded. These cracks occur due to the cyclic stresses induced by the waves causing premature failure. Monitoring these fatigue cracks using a wireless system gives the opportunity to guarantee the integrity of the structure without manual inspection,...

At large oceans depths (5000m) manganese nodules are formed, these are rock shaped objects that contain various rare earth metals, Royal IHC is currently developing equipment to bring these nodules to the shore. The nodules will be transported to the water surface using a Vertical Transport System (VTS).

In the VTS insight of the...

Supercritical CO2 (sCO2) is considered as a working fluid in future Concentrating Solar Power (CSP) applications
to increase the efficiency of the power cycle. Due to the limited experience, the turbine of an sCO2 power cycle is in literature referred to as the component with the highest risk. In this thesis, a design methodology will be...

Ammonia in aqueous environments leads to eutrophication and toxicity of the receiving water body (Metcalf & Eddy, 2003). In order to prevent environmental pollution, ammonia needs to be removed from residual water streams, before the water can be discharged to the aqueous environment (Song et al., 2012). Waste water treatment plants (WWTPs)...

PowerWindow, a built-in Luminescent Solar Concentrator (LSC), is composed of a window glass with thulium doped coating and a CIGS PV-cell strip attached to one glass edge. LSCs can absorb part of the incoming sunlight and re-direct it to the edges, where PV-cells can produce electricity. Light transport efficiency is then determined by several...

Estimators at the production department of Great Lakes Dredge & Dock Company use a number of models to make production estimates for a job. These models require the slurry concentration in the suction arm of a trailing suction hopper dredge (TSHD) as an input. Currently this concentration is estimated based on results of previous projects....

In the ongoing search for (new) highly efficient and cheap photovoltaic materials, orthorhombic barium disilicide has sparked recent interest. Studies have shown that BaSi2 exhibits good electrical properties, a bandgap of 1.3 eV and a high absorption coefficient. However, these studies have mainly been performed on molecular beam epitaxially...

An interesting concept related to photovoltaic energy is Concentrated Photovoltaics (CPV), in which sunlight is focussed on a PV cell through lenses and mirrors, thereby increasing the incident irradiance on the PV cell. Solar concentration is proven to not only increase the output power of PV cells, but also to increase the electrical...

Land reclamations in deltaric areas provide space to meet the demand for a safe place to live and work. Sand, a traditional filling material in some locations is becoming scarcer. An alternative filling material is mud. Mud consists of clay, silt, sand, organic material, water and gas. Therefore, it is a versatile material and difficult to...

In aerospace industry, composites structures are widely used because of their high stiffness to weight ratio. To ease the manufacturing process, components are assembled together using fasteners which leads to introduction of holes in composites. The failure of these composite structures is affected the high stress concentration region around...
