Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

Plastics have become an integral part of modern society due to their versatility and durability.

International trade has played a major role in defining the modern global economy. Trade, however, entangles the environmental pressures of economic sectors, giving the illusion of environmental improvements, while the opposite may be occurring.

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

Welke kansen en bedreigingen vloeien voort uit de institutionele en normatieve diversiteit op het terrein van de rechten van de mens voor de effectieve bescherming van die rechten in een wereld die gekenmerkt wordt door pluralisme?

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.

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Green hydrogen is produced via a process called water electrolysis. During electrolysis water is split into oxygen and hydrogen.

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

The lipids in the uppermost layer of the skin, the stratum corneum (SC), play an important role in the skin barrier function. The three main SC lipid classes are ceramides (CER), cholesterol and free fatty acids.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

Het is het negende jaar op een rij dat de Faculteit Archeologie in de top tien van archeologische instituten wereldwijd staat. De QS World University Rankings by Subject kijkt naar criteria als academische reputatie en citatieratio's.

How can we bridge the gap between experts and the general public?

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

This thesis focuses on the synthesis, characterization and performance towards CO2 electroreduction of mono and bi-metallic particles based on p-block metals

An algorithm is discussed to compute the exponential representation of principal units in a finite extension field F of the p-adic rationals.

Kohei Suzuki and his co-authors reflect on their extensive scholarly experience teaching comparative public administration across diverse countries including Canada, the Netherlands, Qatar, and the United States.

In this thesis, topics relating to the optimization of high-throughput pipelines used for imaging are discussed. In particular, different levels of implementation, i.e., conceptual, software, and hardware, are discussed and the thesis outlines how advances on each level need to be made to make gains…

Wanneer een fysisch systeem symmetrieën bezit gaan deze vaak gepaard met een representatie van de symmetriegroep op een Hilbertruimte. Groepsrepresentaties op Hilbertruimten zijn intensief onderzocht.

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

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.

In dit interdisciplinaire project worden data science technieken toegepast om de interactie tussen de Universiteit en stad Leiden (Town&Gown) kwalitatief en kwantitatief zichtbaar te maken vanaf 1575. Een van de mogelijke invalshoeken voor vervolgonderzoek is diversiteit, met name vanuit de internationale…

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

The subject of this thesis, ‘Approach to Markov Operators on Spaces of Measures by Means of Equicontinuity’, combines an analytical and probabilistic approach to Markov operators.
