This thesis describes a study from both a theoreticaL and an experimental point of view.

In this thesis, we use low-frequency and high-frequency radio observations to address the following questions regarding quasars: is the radio loud/quiet quasar dichotomy real?

The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

PNEC-pro is a user-friendly screening tool for professionals dealing with the assessment of surface water quality. The tool calculates local, watertype specific no-effect concentrations (PNEC) of copper, lead, nickel and zinc based on biotic ligand models (BLMs).

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.

The demand for neodymium-iron-boron (NdFeB) magnets is rapidly growing, while the neodymium supply chain is under pressure. Recycling can alleviate these issues. This thesis investigates the potential for deploying novel magnet recycling technologies and their environmental consequences.

This thesis deals with properties of Jacobians of genus two curves that cover elliptic curves.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

All crested and marbled newts (the genus Triturus) suffer from an unusual genetic abnormality, called a balanced lethal system, that kills exactly half of their offspring. How can a trait so disadvantageous have survived millions of years of natural selection?

This dissertation presents the results of the importance of creativity for ICT-students of Dutch universities of applied sciences (in Dutch: hogescholen), and the functioning of training courses that aim to promote creative abilities is highlighted.

Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

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

In today's volatile market environments, companies must be able to continuously innovate. In this context, innovation does not only refer to the development of new products or business models but often also affects the entire organization, which has to transform its structures, processes, and ways of…

Monoacylglycerol lipase (MAGL) is the principal enzyme responsible for hydrolysis of the endocannabinoid 2-arachidonoylglycerol (2-AG). MAGL inhibition provides several potential therapeutic opportunities, including anti-nociceptive, anti-inflammatory and anti-cancer activity.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

Combinatorial games are games for two competing players, moving in a turn-by-turn fashion, in which there is no chance nor hidden information⁠. Chess, checkers and the simpler tic tac toe are well-known examples of this class of games, as well as game of go⁠.

Over the last decades, aviation safety has improved strongly. As a downside, airline pilots do not have as many opportunities to develop through experience the competencies that they need in critical situations.

The experiments described in this thesis employ local lentiviral knockdowns in brain areas of female zebra finches followed by behavioural assays consisting of preference and Go/Nogo tasks.

LCA has become an important method to study environmental impacts of human activities. Still, there are several methodological issues in LCA that can adversely affect the results reliability.

Een nieuw kabinet, brandhaarden in de wereld en natuurlijk veel wetenschap: dit zijn de vijf verhalen van de Universiteit Leiden die jullie graag lazen in 2024.

De decanen (voorzitters van de faculteitsbesturen) vormen onder voorzitterschap van de rector magnificus de Raad van Decanen (RvD).

Op de dag van de dies begint rector magnificus Carel Stolker aan zijn tweede termijn. Hoe blikt hij terug op de eerste vier jaar en welke plannen heeft hij? Dat vragen burgemeester Lenferink, bestuurskundestudent Mikal Tseggai, hoogleraar Eveline Crone en diverse andere collega’s aan hem.

Religious Studies at Leiden University allows you to study a broad spectrum of religions and their manifestations.

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

De onderzoeksgroep Cyber Security Governance bestudeert de impact van moderne technologie op governance, soevereiniteit, wetshandhaving en internationale betrekkingen, en levert toonaangevend academisch onderzoek en beleidsinzichten.
