This thesis discusses the physical and chemical processes than influence the composition of forming planets.

One of the key discoveries in exoplanet research over the past decade is the abundance of small planets in our Milky Way. Despite their high numbers, our understanding of their atmospheres remains limited, and it is unknown if they possess atmospheres at all.

Carbon dioxide capture and utilization technologies are necessary to create a truly circular economy. The electrochemical reduction of carbon dioxide to formate is an appealing carbon utilization method as it can be performed at room temperature and pressure, it only requires two electrons, and it has…

Many galaxy clusters exhibit bright diffuse radio emission that traces the underlying structure of the intracluster medium (ICM).

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

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).

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.

The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

Multicopper oxidase, laccase, can efficiently reduce oxygen to water and are mostly used in the enzymatic biofuel cells.

Gaucher disease is a rare metabolic disorder, in which a mutation of the enzyme glucocerebrosidase (GBA1) causes buildup of its substrate glucosylceramide and the deacylated counterpart glucosylsphingosine in lysosomes.

This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

The aim of this thesis is to present novel techniques for proving cryptographic schemes secure against quantum adversaries. Most results are within the context of an idealized model called the ‘quantum random-oracle model’.

The complexity of an intelligence problem determines to a great extent the certainty that can be provided by intelligence and security services.

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

In dit artikel onderzoeken de onderzoekers hoe solidariteit begrepen kan worden, rekening houdend met de diversiteit van verhalen, ruimtes, praktijken, lichamen en tijdsperiodes in een stad.

Seagrass is a marine flowering plant with special adaptations to coastal and marine environments, playing a crucial role in providing a wide range of ecosystem services.

A recent study on reintroduced tigers in Panna Tiger Reserve in India reveals that risks from tigers increased more because of human behaviour and people's livestock husbandry practices.

The Vallesian, 11.1-9 Ma, was a special time in the Vallès-Penedes basin near Barcelona, where a biodiversity hotspot existed. Europe had a subtropical climate, with rhinos, forest giraffes, lions, hyenas, flying squirrels and primates.

This dissertation aims to advance understanding of amoeboid single cell migration under the influence of changing physicochemical environmental properties. The particular focus is on the relatively unknown influence of differing physical properties in the extracellular environment, such as the migratory…

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

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.

This article 'Shaping the European External Action Service and its post-Lisbon crisis management structures: an assessment of the EU High Representatives’ political leadership' assesses the role, influence and core aspects of the EU High Representatives’ (HR/VPs) “political leadership” in the context…

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 dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.
