In de zomer van 2023 trokken geïnteresseerden eropuit om de luchtkwaliteit in Leiden in kaart te brengen. Met behulp van een techniek van Brits kunstenaar Robin Price maakten ze het onzichtbare zichtbaar om zo het gesprek over het belang van goede luchtkwaliteit te kunnen starten.

The main aim of this project is to reveal and unravel the invisible histories of the UN, transcending the dominant Western perspective to recover the historical agency of Global South actors. The research will investigate how the UN has both facilitated and limited their role in shaping global order…

Computational thinking, programming, and algorithms form the basic of many of the things that are shaping our world, the way we work, interact, organize ourselves, and even spend our free time with social networks, streaming media, and games. And this transformation is far from being complete, it is…

Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

This thesis describes how to scale down concepts of macroscopic mechanical metamaterials to the thermal scale using a system of flexibly-linked colloids.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

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

Catharanthus roseus (Madagascar periwinkle) produces valuable monoterpenoid indole alkaloids (MIAs) such as vincristine and vinblastine, crucial for cancer treatment.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

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…

Carbonaceous asteroids preserve a record of early solar system processes, where minerals and organic molecules, like polycyclic aromatic hydrocarbons (PAHs), offer clues to planetary evolution and prebiotic chemistry.

Planets are formed in disks of gas and dust around young stars.

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

Endothelial dysfunction and microvascular diseases are key drivers of cardiovascular disease, the world's leading cause of death.

G protein-coupled receptors (GPCRs), one of the largest families of membrane proteins, are responsive to a diverse set of physiological endogenous ligands including hormones and neurotransmitters.

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

This research focuses on the distribution of chemical elements in protoplanetary disks, the birthplaces of planets. These disks form around young stars and contain gas and dust, from which planets grow. Ice plays a crucial role in planet formation, aiding the clumping of dust particles and influencing…

We have studied the impact of particle shape anisotropy, multivalent interactions and flexibility on systems of micron-sized colloidal particles.

PNEC-pro is a user-friendly screening tool for professionals dealing with the assessment of surface water quality. The tool calculates local, watertype specific no-effect concentrations (PNEC) of copper, lead, nickel and zinc based on biotic ligand models (BLMs).

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

This proposed research uses ego-documents from visual artists that were not intended for publication to reassess the scholarly debate on the demise of the Russian Avant-garde aesthetic in the twenties and early thirties of the 20th century.
