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…

Om de klimaatcrisis het hoofd te bieden, kan een bepaalde nederigheid van de mens ten aanzien van de natuur van groot belang zijn. Tegelijkertijd kan nederigheid ook politieke overheersing in de hand werken. Hoe kunnen mensen zich op een bescheidener manier tot de natuur verhouden zonder hun vrijheid…

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

The origin and evolution of galaxies are closely linked to many different physical phenomena.

In this thesis, we present new laboratory data of interstellar dust analogues.

Jan van den Berg heeft zij proefschrift op 8 november 2018 verdedigd.

Ramesh Ganohariti onderzoekt de juridische identiteit in drie post-Sovjet aspirant-lidstaten en schetst in dit artikel vier veelvoorkomende scenario's.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

The increasing resistance of pathogenic bacteria to antibiotics necessitates the discovery of new medicines.

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

In deze publicatie worden problemen met betrekking tot de grensoverschrijdende afwikkeling van financiële instellingen onderzocht.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

Op 2 juli promoveert Jiaqi Wang. Het Leiden University Centre for Linguistics feliciteert Jiaqi!

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

Innovation plays an essential role in firms' competitiveness and long-term success. It varies from different types, ranging from run-of-the-mill innovation that brings incremental changes to existing technologies to radical innovation that breaks from existing trajectories.

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

Promotor: Prof.dr. J.W.M. Frenken

This study seeks to analyse how job stress could be the result of performing administrative tasks

Religion and ethnicity are inextricably linked in discourse within and about Central Asia. One common narrative suggests that as a result of differences between historically sedentary and nomadic populations, ethnic Tajiks and Uzbeks are naturally more religious and more likely to radicalise than their…

This thesis focuses on the role of chemokine receptors CXCR3 and CCR2 in the inflammatory process and infection control using the zebrafish model.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

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…

Jaroslaw Kantorowicz and Rok Spruk onderzoeken de bijdrage van institutionele hervormingen aan economische groei.

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.
