Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

This thesis studies theoretical surface chemistry within the field of heterogeneous catalysis.

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

This thesis is is made of three parts. The first part describes a generalization of the Chabauty's method, that can be used to determine the rational points of a curve such that s+g>r+1, where g is the genusof the curve, r is the rank of the Mordell-Weil group of the jacobian of the curve and s is…

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

With tomography it is possible to reconstruct the interior of an object without destroying.

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.

On 1 October 2019, Emile Cammeraat defended his thesis 'Economic Effects of Social Protection'. The doctoral research was supervised by Prof. K.P. Goudswaard and Prof. P.W.C. Koning.

This thesis consists of two main parts. The first part (Chapters 2 and 3) deals with a class of Markov process called Quasi-Skipfree (QSF) processes.

The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

Are UN sanctions regimes in need of further formalization in terms of substantive design, procedural architecture and with a view to regulating and governing the interplay with other regimes?

In our lab, we investigate the physics and material properties of low-dimensional systems.

In the logic and aesthetics of a republican baroque the existing world is the result of a moment in which for a split second two or more realities are equally real and after which only a singular one becomes actualized.

To what extent can contingent, formative feedback in lectures, facilitated by web-based ICT, increase students’ self-efficacy and (academic, behavioral, and cognitive) engagement? And how are self-efficacy and engagement influencing students’ performance and course evaluations?

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

Learning analytics tracks students’ online learning activities in order to support their learning. But what if most of their learning takes place offline, out of sight of digital eyes?

The research programme Probability Theory focuses on probability theory and on operations research.

What is the impact of research-based learning on critical thinking competence and academic achievement in undergraduate education? What are underlying factors of research-based learning in the learning environment?

What if you could watch a CT scan live, instead of analysing the images afterwards? If it is up to the Leiden mathematician Jan-Willem Buurlage, that will soon be a reality. He is developing methods to make the algorithms behind 3D scans faster. Quite a challenge: ‘Just like mathematicians, computers…

The van Exter group has an extensive history of prior research in classical and quantum optics. As former part of the group of Han Woerdman, we have studied topics as diverse as:

How did colonial law work to turn people into property? This project argues that colonial ideas about households and domestic authority were critical to legal processes of enslavement in the early modern Dutch empire. Using colonial court records from Dutch Brazil, Suriname, and the Moluccas, the project…

This remarkable statement appears in Yi-Wen Cheng’s dissertation on state monopoly and forms of competition in the Chinese tobacco industry. Cheng presents her conclusions and looks back on her fieldwork. ‘I had to accept a lot of drinks in order to establish a network of contacts.’

On Thursday 28 January 2016, Prof. Carsten Stahn contributed to the OPCW Sub-Working Group on Non-State Actors, together with Professors Andrew Clapham (Geneva) and Dapo Akande (Oxford), in the presence of the Ahmet Üzümcü, Director-General of the OPCW.

Over the past two centuries, the concept of human dignity has moved from the fringes to the centre of the international legal system. This book is the first single-authored detailed historical, theoretical and legal investigation of human dignity as a normative value, the intellectual sources that shaped…

In a recent article for the magazine Public Seminar, Santino Regilme argues that democracy across continents is being quietly usurped by a transnational billionaire class.

All microscopic objects, from enzymes to paint particles, are jittering constantly, bombarded by solvent particles: this is called Brownian motion. How does this motion change when the object is flexible instead of rigid? Ruben Verweij, Pepijn Moerman and colleagues published the first measurements…

Exam, paper, exam, paper. A familiar, though sometimes little unexciting, routine for students. That is why Film and Literary students Sietske de Haan and Wouter Dijkman decided to write a blog post for the course Interculturality. Their impressive achievement was rewarded with a publication on science…
