The main aim of this project is to reveal and unravel the invisible histories of the UN, transcending the dominant Western perspective to recover the historical agency of Global South actors. The research will investigate how the UN has both facilitated and limited their role in shaping global order…

Computational thinking, programming, and algorithms form the basic of many of the things that are shaping our world, the way we work, interact, organize ourselves, and even spend our free time with social networks, streaming media, and games. And this transformation is far from being complete, it is…

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

Carbonaceous asteroids preserve a record of early solar system processes, where minerals and organic molecules, like polycyclic aromatic hydrocarbons (PAHs), offer clues to planetary evolution and prebiotic chemistry.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

Catharanthus roseus (Madagascar periwinkle) produces valuable monoterpenoid indole alkaloids (MIAs) such as vincristine and vinblastine, crucial for cancer treatment.

Arithmetic geometry concerns the number-theoretic properties of geometric objects defined by polynomials. Mathematicians are interested in the rational solutions to these geometric objects.

Neurodegenerative diseases pose a large medical and societal challenge. The etiology of these diseases is still poorly understood, which makes drug discovery for these diseases difficult.

Single-layer graphene (SLG) has attracted considerable interest as a proton exchange membrane for direct methanol fuel cells (DMFCs), owing to its atomic thickness, mechanical robustness, and unique proton permeability.

This dissertation explores new chemical strategies for the synthesis of self-adjuvanting peptide conjugates and immunomodulatory ligands aimed at targeted activation of the immune system.

This thesis advances our understanding of lipid uptake, a vital first step in lipid metabolism, by developing innovative click chemistry-based tools to study how immune cells internalize lipids.

This dissertation combines the use of defined microenvironments, high-resolution fluorescence microscopy, and time-resolved analysis, to study intracellular and cellular motility.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.
