In this thesis unconventional tools based on fluidic interfaces were developed to study the surface and interfacial chemistry of graphene, to characterize the intrinsic properties of graphene, to disentangle the effects of substrate and of the environmental factors, and to improve handling protocols…

Traditionally, vaccines are administered intramuscularly using conventional hypodermic needles, which cause pain and distress. Microneedles are very short needles (smaller than 1 mm) that are practically invisible to the naked eye.

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.

Dissolution processes – next to aggregation processes - play an important role for fate prediction and environmental risk assessment of metal-based nanoparticles (MNPs). It is challenging to predict the kinetics of the dissolution process of MNPs in complex systems such as we can find in in vivo and…

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

This thesis investigated miniaturized mass spectrometry (MS)-based analytical methods to address challenges in analyzing biomass-restricted biological samples.

This research delves into the unique cultural approach of the Tenggerese people, an Indigenous community in East Java, Indonesia, regarding elderly care. It focuses on their traditional practices of bakti (‘filial piety’) and sayan (‘mutual aid’), deeply ingrained in the community's lifestyle and va…

Food waste is a defining inefficiency of the modern food system, with profound implications for resource use, climate change, and circular economy transitions. This dissertation examines food waste through two complementary lenses: the prevention of avoidable food waste and the valorization of unavoidable…

Hydrodesulfurization (HDS) is an ubiquitous part of oil refining that ensures that fuels are cleaned of impurities and environment release of pollutants such as SOx and NOx gasses are minimized.

Interactive exploration of large volumes of data is increasingly common, as data scientists attempt to extract interesting information from large opaque data sets. This scenario presents a difficult challenge for traditional database systems, as (1) nothing is known about the query workload in advance,…

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

A common method to solve expensive function evaluation problem is using Bayesian Global Optimization, instead of Evolutionary Algorithms.

Het onderzoek in het natural computing cluster omvat theoretische fundamenten, de ontwikkeling van nieuwe algoritmen en interdisciplinaire toepassingen van natuurlijke computermethoden. De drijvende kracht achter hun onderzoek is de missie om het begrip van natuurlijke systemen als rekenmodellen te…

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

Increasing the efficiency of gene targeting (GT) as a genome editing tool in plants has been an important goal in plant biotechnology.

This thesis utilises the exceptional sensitivity and resolution of LOFAR to explore the low-frequency Universe, while simultaneously advancing the telescope's capabilities to enable new scientific discovery.

Samen wonen in een residentiële setting voegt een extra dimensie toe aan dit leren, omdat onze studenten moeten leren samen te leven met anderen die mogelijk niet dezelfde dagelijkse routines of normen delen.

Understanding DNA repair mechanisms is essential for advancing plant biotechnology and crop improvement. This study investigates how double-strand breaks (DSBs), induced by CRISPR/Cas systems, are repaired in the model plant Arabidopsis thaliana, and how these processes influence Agrobacterium tumefaciens…

Membrane fusion is a vital process in living organisms and is mediated by zipper-like proteins.

Cancer is considered the silent pandemic of the 21st century and the second leading cause of death worldwide.

Het klinkt futuristisch, maar het kan toch: miniatuurorganen van patiënten maken en hierin bestuderen hoe ziektes zich ontwikkelen en behandeld kunnen worden. Dat willen onderzoekers van het LUMC, de Universiteit Twente (UT), UMCG, TU Delft en het Hubrecht Instituut de komende 10 jaar bereiken met een…
