Nanoplastics are detected in surface water, yet accurately quantifying their particle number concentrations remains a significant challenge. In this study, we tested the applicability of a gold-labelling method to quantify nanoplastics in natural organic matter (NOM) containing water matrices. Gelatin-coated gold nanoparticles (Au-gel NPs)...

In forward osmosis, defects on the selective active layer and changes in the porous structure of the support layer can be detrimental factors affecting the membrane performance. This study focuses on the impacts of (i) the possible presence of defects and (ii) the changes in pore structures on the water flux and membrane selectivity via...

To ensure proper development, infants must receive the right amount of nutrients. Since their intake of minerals and trace elements in the first four months comes solely from mother milk or formula, valuable information about the uptake can derived by analyzing their excretion (in the form of feces or urine). Previous studies have used this...

Absolute accuracy plays a crucial role in most geospatial applications. Particularly in the case of mobile mapping systems (MMS) where large amounts of data are collected, it comprises a key factor that can sometimes be dangerously underestimated. Within the scope of mobile laser scanning, the accuracy of the measurements is mainly ruled by the...

Multi-element (ME) datasets provide comprehensive geochemical signatures of an orebody and are commonly used to gain insight into the mineralogy, lithology, alteration patterns and to identify target-pathfinders. However, little effort is made in using these data to explain comminution or recovery characteristics. This paper describes an...

The optimization of mesa etch for a quasi-vertical gallium nitride (GaN) Schottky barrier diode (SBD) by inductively coupled plasma (ICP) etching was comprehensively investigated in this work, including selection of the etching mask, ICP power, radio frequency (RF) power, ratio of mixed gas, flow rate, and chamber pressure, etc. In particular...

An upper limb prosthesis, i.e. a hand prosthesis, is a device to replace the function of an upper limb on upper limb amputees. In developing countries, amputees’ access to the device is scarce to unavailable. In addition to the absence of experts in those areas, currently there are no automatic measurement methods for upper limb amputees...

Usually, oil fields are developed over three stages. First is the primary oil recovery, where the natural underground pressure is used to drive the oil to the surface. Afterwards is the secondary oil recovery, usually by water flooding or gas injection. However, the water flood yields lower sweep efficiency in heterogeneous reservoirs, contrary...

Analytical ceramic studies offer the opportunity to determine cultural development and change on the basis of origin and use of raw materials. In this particular study, an archaeometric approach on ceramics in central Pisidia contributes to the discussion of contact and exchange between indigenous communities and several cultural spheres of...

Iron is an essential trace element involved in many processes in the human body. Some disorders like iron deficiency anaemia and haemochromatosis directly result from changes in iron status, while on the other hand iron metabolism changes during illness. Since these adjustments in the iron handling of the body may have consequences for the...

A method for highly controllable etching of AlGaN/GaN for the fabrication of high sensitivity HEMT based sensors is developed. The process consists of cyclic oxidation of nitride with O<sub>2</sub> plasma using ICP-RIE etcher followed by wet etching of the oxidized layer. Previously reported cyclic oxidation-based GaN etching obtained very...

To demonstrate the possibility of using EBID masks for sub-10 nm pattern transfer into silicon, first experiments were carried out by using 20-40 nm EBID masks, that were etched by different chemistries. It is experimentally verified that recipes based on hydrogen bromide, chlorine and boron trichloride can selectively etch silicon when using 20...

Metalloproteomics is a rapidly developing field of science that involves the comprehensive analysis of all metal-containing or metal-binding proteins in a biological sample. The purpose of this review is to offer a comprehensive overview of the research involving approaches that can be categorized as inductively coupled plasma (ICP)-MS based...

Facade reconstruction from terrestrial LiDAR point cloud is affected by both quality of point cloud itself and imperfectness of object recognition algorithms. In the facade, there are many features, which are shared within an object or among objects. For example, within one window, the boundaries of it may share parallel and orthogonal...

With a growing threat from space debris, it has become more important for space agencies to have a means of reducing the probability of escalating the dangers posed by it. For this purpose, servicer satellites need to be built. These satellites need to be able to interfere with “dead” satellites and deorbit defunct satellites. In order to be...

Low-cost sensor generated 3D models can be useful for quick 3D urban model updating, yet the quality of the models is questionable. In this article, we evaluate the reliability of an automatic point cloud generation method using multi-view iPhone images or an iPhone video file as an input. We register such automatically generated point cloud...

A 3D face recognition algorithm has been developed for the Microsoft Kinect in the scope of the final bachelor project at the TU Delft in 2013. The aim of the project is to develop a prototype face recognition system. The prototype system had to outperform the existing 2D face recognition system. The project is divided into three subgroups each...

Chlorine-based inductively coupled plasma etching processes are investigated for the purpose of etching twodimensional photonic crystals in InP-based materials. Etch rates up to 3.7 µm/min and selectivity’s to the SiN mask up to 19 are reported. For the removal of indiumchloride etch products both the application of elevated temperatures and...

This thesis deals with the dry etching of deep anisotropic microstructures in monocrystalline silicon by high-density plasmas. High aspect ratio trenches are necessary in the fabrication of sensitive inertial devices such as accellerometers and gyroscopes. The etching of silicon in fluorine-based plasmas is isotropic. To obtain anisotropy the...
