Bergwerf, R. (author)This master thesis deals with the research to the effects of severe plastic deformation on the development of the microstructure and the mechanical properties of three low-alloyed high-carbon steels. The steels investigated include a hypo-eutectoid, an eutectoid and a hyper-eutectoid steel containing 0.61, 0.81 and 1.22 weight-percent carbon....master thesis 2007

Arikan, S. (author)Electron microscopy makes it possible to magnify samples at almost atom level by using electron beams to scan the sample. These images could be improved in terms of noise and sharpness. In this research we looked into the possibilities to use post-processing filters for improving the quality of electron microscopic images.master thesis 2009

Morsink, D.W. (author)Nowadays both fluorescence and scanning electron microscopy are highly developed imaging techniques that are commonly used in many fields of research. As both techniques have their own strengths and weaknesses, a combination of both techniques can complement each other in certain fields of research. The combination of these two imaging...master thesis 2013

He, X. (author)Background Interferometers and capacitance sensors were used to measure the motion of the 6-DoF ferrofluid planar bearing positioning stage designed by Max Cafe who was the master student graduated in 2014. The sensor costs almost 30,000 euro to achieve nanometer scale accuracy. However, in some biology applications, such as observation of...master thesis 2014

Van der Velde, O. (author)Over the years, glass has been increasingly used as a structural building material. Structural calculations on glass are conservative because the strength is quite uncertain. Weibull plots of the strength of glass can range from 20 MPa to 150 MPa. This is caused by flaws, which are not visibile to the human eye and therefore it is difficult to...master thesis 2015

Van Groeningen, D.T. (author)We have investigated the possibility of using prior knowledge about a sample in order to improve the image quality of localisation microscopy. We assumed that all fluorescent molecules were aligned on one, or two parallel line segments and used this assumption to develop an estimator for the emitter locations and the line parameters. Using...bachelor thesis 2015

De Boer, F.Q. (author)Lithium silicon (Li-Si) batteries offer more than ten times the theoretical specific capacity compared to current lithium ion battery technologies, by using a silicon anode. In practice however, the cycle life of Li-Si batteries is very limited. The large volume change of the silicon anode is known to be the main reason for this. Research on the...bachelor thesis 2015

Bouwens, M.A.J. (author)In this thesis a stealth fiducial marker system for blank wafers is designed, fabricated and validated. The goal of this marker system it to map the coordinates of TNO’s Rapid Nano (a fast optical inspection tool) to the coordinates of scanning electron microscopes and atomic force microscopes. This way defects, that have been detected in the...master thesis 2015

Bucsa, R.E. (author)In the DCSC group of Prof. Michel Verhaegen a new type of fluorescence microscope has been developed that relies on adaptive optics to correct for aberrations using optimisation of an image metric. The aim of this thesis is to realise a complete simulation of the optical system, and to test a variety of optimisation algorithms in simulation,...master thesis 2016

Spruit, Ronald (author)Transmission electron microscopy is a powerful and commonly used tool to study nanoparticles, nanowires and 2D materials. It provides static information from the sample with atomic resolution, in high vacuum and at ambient temperature. However, in real processes, the environment is often different and dynamic.<br/><br/> MEMS-based sample...master thesis 2017

Gribnau, Thomas (author)Since its invention, the Atomic Force Microscope has emerged into one of the most useful tools in<br/>nanotechnology due to its acclaimed abilities in exploring surface topography, micro- and nanoscale manipulation<br/>and characterization. The nonlinear interaction between the cantilever tip and the sample surface<br/>has been studied in great...master thesis 2017

Goossen, Levar (author)<br/>Nanocatalysis has received considerable attention in the scientific community due to their superior reactivity compared to their macro-sized counterparts. MEMS nanoreactors allow scientists to view these reactions in-situ. This opens up doors to finally understanding the underlying mechanisms of the nanocatalyst's effectiveness, which may...master thesis 2018

Fuchs, Dominique (author)Aseptic loosening is a major cause of revision surgery in total hip arthroplasties. To slow down, or reverse loosening, tissue engineering interventions could provide solutions. One possible solution is collagen crosslinking, increasing the stiffness of the tissue. This research is a first investigation into UV-induced crosslinking on tissue...master thesis 2018

Garzon Amortegui, Juan Felipe (author)W/C is a fundamental parameter for concrete mix design, it defines the properties in the fresh and hardened state as well as the durability of the material. Nevertheless, once the concrete has hardened, it is very difficult to estimate the W/C in the original mix design, so far only 2 methodologies has been accepted as a standards. Because of...master thesis 2018

Melching, Willem (author)Super Resolution Microscopy is a technique to image objects with resolution higher than the diffraction limit, the fundamental limit to the resolution of a microscope. One of the techniques used for Super Resolution Microscopy is Single Molecule Localization Microscopy (SMLM). For this method, a sample is labeled using fluorophores (fluorescent...master thesis 2019

Noom, Jacques (author)Currently used imaging methods in Atomic Force Microscopy (AFM) including the use of a Lock-In Amplifier or a Phase-Locked Loop, are suboptimal. In this report, the image resolution in AFM is improved by detecting the tip-sample interaction using complete measurements of the input of the cantilever and its measured deflection. Two methods are...master thesis 2019

Karanth, Pranav (author)Metal anode based batteries, considered the ideal upgrade to Lithium ion batteries in terms of energy density, are currently held back by the non-homogeneous deposition phenomenon that leads to the formation of dendrites that short circuit the cell. The solution to this problem is twofold: while it is important to come up with solutions that...master thesis 2019

James, Matthew (author)Dynamic Atomic Force Microscopy (dAFM) is an extremely powerful tool for exploring surface topology and nanoscale manipulation and characterization. A feature of dAFM is the existence of highly nonlinear forces between a cantilever tip and sample. One of these forces that plays a large role in operation of AFM is the van der Waals (vdW) force....master thesis 2019
