Connolly, Ronan (author)Ice accumulation on aircraft surfaces is a prevalent issue, and icephobic coating strategies can be implemented to assist in the removal of or ice on an aircraft. However little is known regarding the effects of novel icephobic coatings and surfaces on ice adhesion strength, which is difficult to measure and quantify, and is typically reported...master thesis 2024

van der Gugten, Gijs (author)Much research is conducted on the biomechanical properties of cells, particularly in cancer research. Cell stiffness and cell adhesion are two properties often studied, because they are important for the functioning of a cell. To study these properties, atomic force microscopy(AFM) is often used, using nanoindentation for stiffness analysis and...master thesis 2023

Mooijman, Tom (author)Enceladus, one of the icy moons of Saturn, has been of major scientific interest since the Cassini-Huygens mission has explored the Saturn system. This is due to cryovolcanic geysers with complex organic molecules and other ingredients for life in it blasting into space from its subglacial warm ocean. The moon's harsh environmental conditions...master thesis 2023

Koel, Lars (author)A Helically wrapped structure is a hollow pipe structure that is made from a metal strip and the overlapping interfaces are adhesively joined. It is yet unknown how to determine the quasi-static strength and predict the fatigue life of this structure. A method was developed to determine whether either the adherend or the adhesive is critical to...master thesis 2023

Glaser, Niels (author)Dry adhesives can reattach to surfaces due to the reversible bond made by Van der Waals forces. These adhesives can therefore be used as gripping surface that has a high frictional load capacity, independent of the grasping force. In many grippers, the adhesive surface is often pressed into contact with another surface (’substrate’) in an open...master thesis 2022

van den Boogaart, Luc (author)To avoid detection during a bloodmeal, a mosquito must minimize contact forces during attachment and detachment contact while maintaining sufficient grip to insert their proboscis and feed. Measuring contact mechanics of the mosquito is technically challenging due to the small length and force scales. Because of this, many aspects of blood...master thesis 2021

Jongerius, Camiel (author)The study of adhesion mechanisms in animals such as the gecko has helped mankind with the understanding and development of novel adhesives. The adhesion mechanism of the tree frog is not fully understood, it is a wet adhesion mechanism which works differently than the dry adhesion mechanisms of animals, such as the gecko, studied previously. The...master thesis 2021

Kisa, Mehmet (author)Gas extractions are responsible for mostly all induced earthquakes in the Groningen area and this leads to damage of houses and buildings and issues regarding safety. Current strengthening measurements are mostly very visible. However, this can change by using the window frame as part of the structure, particularly interesting for Dutch houses...master thesis 2021

Copier, Rick (author)Objective: this paper aims to evaluate the adhesive and frictional properties of the keratinised epithelium on the adhesive pads of tree frogs. Modeling methods: two modeling methods have been developed. One of these methods involves the implementation of discrete fibres in a relatively compliant material matrix while the other method involves...master thesis 2021

Callens, Lander (author)Unlike traditional wet-adhesives, dry adhesives are bioinspired solid polymers that owe their adhesion to hierarchical structures. Gecko’s are the most recognizable living creatures relying on this concept to climb walls. A close look at the gecko’s fingers reveals a hierarchical system of micro-and nanoscale filaments. These ensure excellent...master thesis 2020

Frints, Ivo (author)Osteoarthritis, the degeneration of articular cartilage, which causes loss of mobility and chronic pain for patients is a common condition with high clinical demand. Care of this condition currently attributes to ±1.4% of the Dutch annual health care costs, but due to the rapidly aging Dutch population a 41% increase of cases is projected over...master thesis 2020

Hoogerwaard, Geert (author)Despite the increased popularity of the application of load bearing glass in the built environment, its design does rarely address sustainable or circular aspects. This Master’s Thesis analyses what the influence of connections is on the sustainable performance of structural glass and informs about the limitations and possibilities of sustainable...master thesis 2020

Haitsma Mulier, Babette (author)Drainage of fluid from wet adhesive-substrate interfaces is often mentioned to be an important mechanism in obtaining strong grip. It has been hypothesized that micropatterned adhesives – that contain features (e.g., pillars) separated by channels on their surface – have a better drainage capability compared to unpatterned adhesives....master thesis 2020

van 't Laar, Vincent (author)In the past decades extreme weather events have become more common as a result of climate change, which is brought on by the increasing concentrations of greenhouse gasses in the atmosphere. Climate change and sustainable development are motivators for the research topic of this thesis, since the prevention of a climate crisis is favourable to...master thesis 2020

Haring, Frank (author)For over a decade the use of bio inspired adhesives have been explored to achieve high reversable attachment on a wide range of surfaces. Based on the fibrillar adhesive toepads of geckos, many patterned adhesives have been produced that are able to form and preserve contact with rigid and smooth substrates. But on other types of surfaces, such...master thesis 2020

Balasubramanian, Manikandan (author)Coating deposition by Physical Vapour Deposition (PVD) on high strength steels is an important research project at TATA Steel - IJmuiden. The research is aimed at replacing the conventional hot-dip galvanisation process to obtain a defect-free coating without affecting their well-engineered properties. However, the annealing treatment of the...master thesis 2020

ten Bruggencate, Thijs (author)For this Master thesis the possibility was explored to use a monolayer of graphene as conductive layer, instead of sputtered titanium nitride (TiN), on 25 nm thick aluminium oxide and magnesium oxide membranes. These membranes will be used in a new and faster variant of a vacuum electron multiplier (e.g. the Photo Multiplier Tube (PMT)). These...master thesis 2019

Hoogeveen, Erik (author)Context: The shift to green energy offers a need for offshore wind farms. The transition from a relatively cheap energy production from carbohydrates, to a young offshore wind energy industry needs innovations to lower the cost. Increasing the efficiency of wind turbines and lowering the installation cost of a wind farm, will eventually make...master thesis 2019

De Geyndt, Wouter (author)With growing interest in wet adhesion, animals such as tree frogs are often used as paradigm for creating grippers in wet environments. Tree frogs are capable of attaching to surfaces under several conditions (smooth, rough, dry, wet, and flooded) due to the microstructure of their toe pads. This microstructure consists of pillar-shaped...master thesis 2019

Cheung, Eunice (author)Gecko-inspired adhesives mimic the external structure of geckos with micropatterned surfaces and the internal structure by fabric reinforcement in soft elastomer adhesive pads. Previous research measured the friction forces of synthetic adhesives, with either an external or internal structure, mainly on hard substrates. Much less is known about...master thesis 2019
