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

The use of N fertilizers has increased worldwide in the past century. While this increased input of N has increased food productivity, it has also contributed to decreases in biodiversity, soil quality and environmental health, including increases in greenhouse gas emissions.

A complex community of microbes develops in the infant gut shortly after birth. We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study.

The experiences of ethnic ‘Other’ females have – until recently – been widely overlooked in the study of sport. There continues to be a need to produce critical scholarship about ethnic 'Other' girls and women in sport and physical culture, in order to represent their complex, multifarious and dynamic…

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.

This study has been carried out in the community of Sukamiskin, a kelurahan (‘village’) in Bandung, the Capital of West Java Province, located in the Sunda Region of Indonesia.

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

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.

Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

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.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

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