Governments are increasingly facilitating the roll-out of so-called “smart meters”, a technology for measuring energy consumption that are able to transmit and receive data using a form of electronic communication. However, implementation has been slow or even stalled.

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.

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

This thesis develops a method for direction dependent calibration of the ionosphere in radio interferometric data.

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

Carbon dioxide capture and utilization technologies are necessary to create a truly circular economy. The electrochemical reduction of carbon dioxide to formate is an appealing carbon utilization method as it can be performed at room temperature and pressure, it only requires two electrons, and it has…

Dynamic nuclear polarization with paramagnetic agents can enhance nuclear magnetic resonance signals by orders of magnitude. The mechanism of enhancement depends a.o. on the magnetic resonance properties of the agents used. Electron spin relaxation times at NMR relevant magnetic field/microwave frequencies,…

With textnets it is possible to visualize and analyze textual data in novel ways.

This thesis focuses on the concepts of freedo and fixity as two central topics of my artistic research. I present, analyze. and contextualize four of my works which have explicit links to fleedom and fixify and which demonstrate the dynamic interrelationship between the two.

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…

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

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

These aspects make the Media Technology MSc program unique:

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

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

This book is the first systematic analysis of the changes in the use of goods and services by households of Black South Africans since the early nineteenth century.

This is the physics summer school of Leiden University. It is part of the Leiden Institute of Physics (LION). The summer school is intended for Bachelor (BSc) students in physics. It covers topics from quantum matter and optics, to biological & soft matter physics and cosmology and theoretical physics.…

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

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)…

The Academy of Creative and Performing Arts (ACPA) provides artistic research and education in the arts.

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).

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.
