Today, knowledge is the most crucial element to stimulate organizational competitiveness and economic development.

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

My research addresses the function of the much-debated particle -nā in Biblical Hebrew, often translated with “please”, from the point of view of the most important ancient Bible translations (Greek, Syriac, Latin). It combines textual criticism, translation technique, discourse pragmatics, and the…

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

Humanity stands at a pivotal juncture, facing the dual challenge of environmental sustainability and rapid population growth, projected to exceed 11 billion by century’s end.

Preterm birth is a major contributor to neonatal morbidity and mortality and is associated with both acute complications and long-term health consequences.

It appears to be a paradox: ultra-thin material that absorbs all the incident light. Nonetheless, it does exist. Two Leiden researchers report on their research in ‘Applied Physics Letters’. The article is among the Top 20 of the most downloaded articles of this reputable journal in May.

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

The overall theme of this thesis is to complement the electrochemical data acquired in fuel cell research with in situ X-ray photoelectron spectroscopy (XPS) and soft X-ray absorption spectroscopy (XAS).

Molecules are extremely hard to see in visible light, especially without using fluorescence. Leiden physicists have now made their optical technique sensitive enough to image the molecules of their interest in all sizes. Publication in Nanoletters.

The confinement of molecular catalysts in metal-organic frameworks has the potential to lead to significant improvements in selectivity, long term activity and catalyst stability.

From descriptive to physiological models that can predict oral absorption and elimination of CYP3A substrates across the pediatric age range.

Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

In dit onderzoek worden orde isomorfismen en orde antimorfisme bestudeerd in het algemene kader van partieel geordende vector ruimten.

The aim of ANCIENT CHARM was to develop neutron-imaging techniques and the associated equipment, and help establish neutron imaging as a mainstream archaeological analytical technique. In particular, one of the goals was a new imaging technique which called neutron resonant capture imaging combined…

Fungal infections pose a significant threat to individuals with compromised immune systems and despite advancements in diagnosis and treatment, they continue to jeopardize patient’s health.

We have conducted a full spectral line survey of the 3-13 micron region of two massive protostars, AFGL 2591 and AFGL 2136, for the first time at high spectral resolution.

Considering the absence of the human performer within a performance installation, the research centres around what is left of the human through traces such as sound or recorded voices, images, videos or movement and gestures. What do we perceive as ‚present‘, once the human is removed from the centre…

The data-driven economy allows for the collection and processing of large amounts of data. Such data can be used to optimize profits by (dynamically) differentiating prices for different consumers.

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

Complex Organic Molecules (COMs) have been detected in objects across different stages of stellar evolution.

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

In this book, Sarah Giest, Assistant Professor at the Institute of Public Administration, provides insight into the collaborative and absorptive capacities needed to provide public support to local innovation through cluster organizations.

Cathodic corrosion is a relatively unknown phenomenon that can severely etch metallic electrodes at cathodic (negative) potentials.

The main goal of the research described in this thesis was the development of new photoactivated chemotherapy (PACT) ruthenium(II) complexes bearing a non-toxic photolabile ligand.
