What holds people together and what makes them willing to fit within larger political structures? Our project examines this question in the practices of dynastic rulership in Eurasia ca. 1300-1800.

Kidney transplantation is a major advance of modern medicine. This course will give you state of the art updates about what used to be an experimental, risky, and very limited treatment option more than 50 years ago and is now routinely performed in many countries worldwide.

We are very excited to announce our Sustainability Series for 2023-2024. Each month an interactive workshop will be organised that discusses a specific theme of sustainability. Interested about sustainability? Do not hesitate to sign up to our events !

Artificial photosynthesis has recognised potential to produce green and sustainable fuels from earth-abundant resources such as water, carbon dioxide (CO2), and sunlight.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

The goal of the project is the development of stream mining techniques for complex patterns such as graphs. We will try to extend the existing state-of-the-art techniques into two, orthogonal directions: on the one hand, the mining of more complex patterns in streams, such as sequential patterns and…

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.

This Thesis describes a strategy to synthesize 1,2-cis-oligosaccharides modulated by additives, such as dimethylformamide (DMF), triphenylphosphine oxide (Ph3P=O) and N-methyl(phenyl)formamide (MPF), using building blocks that carry solely benzyl type protecting groups and are therefore of uniform r…

The key characteristic of active matter is the motion of an emergent collection (such as a flock of birds), which is driven by the consumption of energy by its active components (i.e. individual birds).

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

Electron microscopy has become an extremely important techniquein a wide variety of elds.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

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.

Een sterrenstelsel kan groeien door gas uit zijn directe omgeving naar binnen te trekken. Maar astronomen weten nog niet precies hoe dit gebeurt. Sterrenkundige Joop Schaye gaat met een Europese onderzoekssubsidie van 1,5 miljoen euro op zoek naar antwoorden.

De Universiteit Leiden staat midden in de maatschappij en wil bijdragen aan een duurzame samenleving. Verduurzaming van gebouwen levert een bijdrage aan Nederlandse en Europese milieunormen. De Universiteit Leiden houdt daar in al haar bouwprojecten rekening mee.

We found that, next to the effectiveness of the intervention, it’s also very likely that the intervention is cost-effective compared to attention only.

This thesis examines silicon pore optics (SPO), a technology that exploits silicon wafers from the semiconductor industry to create extremely high quality X-ray optics, by studying its manufacturing process, applications, and prospects.

Optical cavities are useful tools to enhance the interaction between light and matter, which is important to make good quantum emitters. However, it turns out that the cavities themselves (without any quantum emitters) are already interesting objects to study.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations.

In this thesis we study products of linear error correcting codes.

An objective of this research was to achieve direct, well-defined and non-rate-limiting electron transfer between respiratory enzymes and the electrode surface by means of 'Q-wires'.

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.

This dissertation is a collection of four research articles devoted to the study of Kummer theory for commutative algebraic groups.

A Josephson junction is a device where a thin insulating barrier or a nanostructure is placed between two superconducting leads. Such a junction is essential to superconducting qubits that store quantum information due to its anharmonic spectrum.

The research group Politics, Culture and National Identities 1789-present investigates a wide range of national political cultures in Europe and the Americas in the 19th and 20th centuries. Instead of only analyzing high politics (the acts of governments and political parties), the research group focuses…

This PhD-thesis presents a study on micron-sized particles, so-called colloids. By controlling the chemical and physical properties of these particles, such as the interparticle interaction and the particles’ shape, colloids can act as building blocks that self-assembly into larger structures.

Machine Learning is becoming a more and more substantial technology for industry.

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

Real-life processes are characterized by dynamics involving time. Examples are walking, sleeping, disease progress in medical treatment, and events in a workflow.

This thesis addresses the problem of designing performance and energy efficient embedded streaming systems, that is, systems which process a stream of input data coming from the environment and generate a stream of output data going into the environment.
