The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

Natural vanilla flavor is one of the most important in the world. However, the cost of this flavor is expensive. Production of this flavor by alternative methods, could reduce the cost.

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

The type-IV secretion system (T4SS) is a machinery able to transfer DNA and proteins between bacteria and in certain cases also to eukaryotic cells.

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

Inflammatory skin diseases such as psoriasis and atopic dermatitis can severely impact both the physical and social aspect of a patient’s life. Aberrant inflammatory responses are thought to be a major causative factor in these disorders, but an abundance of different factors contribute to the development…

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

Breast cancer is the most common cancer in women worldwide. Metastasis, the process by which cancer cells spread to other parts of the body, makes treatments less effective. It is important to unravel the mechanism of metastasis.

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…

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

The recently introduced nature-originated deep eutectic solvents, so-called natural deep eutectic solvents (NADES) are considered as truly green solvents, which composed of natural ingredients found abundantly in organisms.

This dissertation advances automated negotiation by developing agents that can learn and adapt across diverse negotiation settings through three increasingly sophisticated approaches: automated algorithm configuration, portfolio-based strategy selection, and end-to-end reinforcement learning with graph…

Empirical Legal Studies in Leiden focuste op het bouwen van een interdisciplinaire gemeenschap van rechtsgeleerden en sociale wetenschappers die samen juridische vraagstukken onderzochten op het snijpunt van recht en gedrag, waarbij diverse soorten methoden werden gebruikt.

Atherosclerosis is a progressive disease resulting in the formation of an arterial plaque. Despite lipid lowering, recurrent cardiovascular events remain a risk. While atherosclerosis is primarily lipid-driven, the immune system plays a critical role in the pathophysiology.

How do you engage society to stop biodiversity loss? How do you create political and social involvement to deal with climate change? And how do you balance the economic needs of industry with the negative effects of pollution? If you find these kinds of questions interesting, then this Pre-University…

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

In this thesis, mathematical modeling and simulation was applied as a tool to inform quantitative decision making in oncology drug discovery and development.

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.
