Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

The thesis is part of a bigger project, the HEPGAME (High Energy Physics Game). The main objective for HEPGAME is the utilization of AI solutions, particularly by using MCTS for simplification of HEP calculations.

In this thesis, we investigate how deep generative models (AI models that can create new designs) can be better utilized for technical and industrial design. Our goal is to generate designs that are not only realistic (plausible), but also efficient, reliable, and usable in complex 2D and 3D applica…

Actinobacteria are well known for the production of bioactive natural products, many of which have applications in the fields of human, animal and plant health. Subject of this thesis are the anthracyclines, glycosylated aromatic polyketides with potent anticancer activity.

Its idyllic setting and white sandy beaches have made the Maldives a hotspot for tourists. This provides an income but is a problem for the fragile natural environment. Students from various universities worked with the local people to make the soil more fertile. How did they go about it?

Higher design and engineering educators have different views on what a new or renewed curriculum should entail, content-wise as well as pedagogically. This research aims to describe how these ‘curriculum perspective perceptions’ influence working definitions, end goal formulation, and the scope of results…

Advances in the field of high-performance Nd-Fe-B permanent magnets, by re-engineering their microstructure to make them more powerful while reducing rare earth content.

Bandura Witharana defended his thesis on 27 September 2018

Healthcare Information Systems (HIS) are essential for modern healthcare delivery, yet their development faces significant challenges including heterogeneous data formats, regulatory compliance, and the growing demand for AI-driven decision support.

A main goal of MSBB research is to address the major bottle-necks in combatting viral diseases: the lack of experimental models that are representative of human pathology and are cost effective and versatile. Viral diseases such as those that cause viral hemorrhagic syndromes or severe acute respiratory…

Mashaghi lab conducts research at the interface of physics, engineering and biomedicine. We develop and use theoretical and experimental approaches to address basic and applied research problems.

Apps that can precisely identify shards, coins or heel bones: archaeology has embraced artificial intelligence. Alex Brandsen is working on a search engine that scans vast quantities of text from an archaeological viewpoint.

An examination of academic organization at the forefront of the biotechnology revolution

Engineered nanomaterials (ENMs) are widely used, and nanotechnological innovations grow with rapid pace. Studies on nanotoxicology have demonstrated that chemical toxicology as well as particle toxicology should be accounted for in predicting the safety of ENMs.

Leiden physicist Carlo Beenakker has received an honorary doctorate from the Bogoliubov Institute for theoretical physics in Kiev.

Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

The main focus of this thesis is the behaviour of two-dimensional materials, namely (anti)-ferromagnetic materials in the first two chapters, which show topological phases, and energetic square ice in the third and fourth chapter.

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

The intradermal administration route is attractive for vaccine delivery, because of the highly populated antigen-presenting cells in the skin. However, the skin’s main physical barrier, the stratum corneum, prevents vaccines from entering the skin.

The discussion on employability of higher education graduates has been around for several years, with more emphasis in the 21st century. Yet, universities are still challenged in the pursuit of providing work-ready graduates who can meet industry expectations.

The remains of Dutch East India Company forts are scattered throughout littoral Asia and Africa. But how important were the specific characteristics of European bastion-trace fortifications to early modern European expansion?

This thesis examines enzyme domain architecture and engineering to improve the breakdown of lignocellulose and starch, abundant biopolymers crucial for sustainable biofuel and biochemical production. Carbohydrate-active enzymes (CAZymes) facilitate this degradation, but the structural complexity of…

Are quantum computers the scientific breakthrough of our time? In this podcast, Carlo Beenakker, Professor of Physics at Leiden University, explains quantum technology.

This book investigates how the rulers of the Habsburg world empire developed and implemented a central maritime policy for the Netherlands and appointed an admiral of the sea or admiral-general for that purpose.

In this thesis, we examine various systems through the lens of several numerical methods.

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

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,…

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

The findings in this thesis improve the understanding of 1) the relationship between exposure characteristics and toxicity of ENPs, 2) the joint toxic action of ENP mixtures and the comparison to metal salt mixtures, 3) how NOM affects the individual and joint toxicity of ENPs, 4) the extent of trophic…

Immune system defends our body against pathogens and cancerous cells, but excessive immunity can in turn lead to tissue damages and diseases. For example, scratching the surface of the eye ignites an immune response that aims at preventing infection but can also lead to edema, angiogenesis and eventually…
