Archaeometric analysis of glazed pottery assemblages from the Early Byzantine to the Early Modern periods in the Aegean.

Research at the BPOC/SSNMR group is comprised of the following research themes:

Humanity stands at a pivotal juncture, facing the dual challenge of environmental sustainability and rapid population growth, projected to exceed 11 billion by century’s end.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

The HJD Article Award is a biannual award given to the published research article which best advances the theoretical and/or empirical study of diplomacy.

Tin electrodeposition applications have rapidly evolved in the past 25 years.

Our cantilevers have a low intrinsic damping rate: this enables us to measure with low noise, since damping is proportionate to noise. However, when the magnet is close to the surface of a sample we want to study, we measure a much higher effective damping rate. This is caused by magnetic interaction…

Develop EPR instrumentation and methodology to investigate intrinsically disordered proteins (IDPs).

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

Surface acoustic waves (SAWs) are mechanical waves that travel along the surface of a material and find many applications in modern technologies due to the ease of excitation on piezoelectric substrates via interdigital transducers (IDTs).

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

PURPOSE: In the present study we investigated the root-cause of an interference signal (100-200 nm) of sugar-containing solutions in dynamic light scattering (DLS) and nanoparticle tracking analysis (NTA) and its consequences for the analysis of particles in biopharmaceutical drug products.

This doctoral trajectory explores sound, its image and its role in relating humans and our technologies to the environment.

This dissertation revolves around the design and implementation of novel instrumentation and related measurement techniques, at the single molecule level, for use in biophysical research. Chapter 1 presents an introduction to the field of fluorescence-based single molecule measurements. In particular,…

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.

Technologies that help to enhance our educational environments can be found everywhere.

The project Multimedia Research and Documentation of African Oral Genres: Connecting Diasporas and Local Audiences (Director: D.Merolla) focuses on multimedia as technology that allows scholars to share documentation and scientific knowledge with the cultural owners of the collected oral genres.

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.

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

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

This thesis focuses on developing wafer-scale two-dimensional (2D) materials by combining synthesis, transfer, characterization, and device integration of graphene, hexagonal boron nitride (h-BN), and BN-doped amorphous carbon.

These aspects make the Creative Intelligence & Technology MSc program unique:

In my research, I used a comparative wood anatomical approach to address wood evolution of the (largely) tropical flowering plant families Apocynaceae and Sapotaceae.

Traditional biochemical methods for studying organelles require cell disruption, preventing the real-time observation of dynamic intracellular processes.

Moving an electron microscope of 2000 kg is a delicate challenge. The highly sensitive instrument needed to be moved to a new measurement hall, but even a tiny bump could damage it. After a few nerve-racking weeks of preparing the move and reinstalment, the researchers finally have a verdict: the instrument…

Research projects for students of the University of Leiden and other Dutch Universities are often available at the MacBio group. The research lines are also described in the Research section. For details of specific projects contact the supervisor (Ubbink, Dame, Boyle, Jeuken or Wentink).

How can we understand the drum-set – and thus drummer – as technological? How have technological developments affected change in drum-set performance and drum-set construction? Are the relationships between new technologies and the drummer symbiotic, or one way? To what extent are instruments and (reactive)…

Here are some systems and infrastructures that are useful to students.

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

We are a dynamic research group at the Leiden Institute of Physics. Our aim is to explore and understand quantum materials, including strange metals, high-temperature superconductors, and quantum critical electron matter.

Leiden University policy requires researchers to make all their Leiden-affiliated peer-reviewed articles available.

Leiden University has an Open Access policy and a Copyright Information Office.

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

Have you ever wondered what makes immigrants legally different no matter which legal system they have moved into and no matter what rights have been granted there? Have you ever wondered why immigrants are considered ‘the other’ despite claims that their ‘integration’ and non-discrimination is a top…
