Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

The skin is our natural barrier and lipids are a key part of this barrier. In the outer skin layer, the stratum corneum (SC), lipids form a densely organized structure dependent on the composition of these lipids.

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

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

How soil microbial composition impacts structure and composition of the aboveground plant and animal communities?

To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

Componist Aart Strootman won de prestigieuze Matthijs Vermeulenprijs 2019 voor zijn ensemblewerk ‘Shambling Emerge – after after party’. NRC sprak met hem over zijn compositie, zijn fascinatie voor het sleutelen aan instrumenten en zijn onderzoek.

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…

Mechanical metamaterials are man-made materials which derive their unusual properties from their structure rather than their composition.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

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.

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

Aspergillus niger is an important industrial producer of organic acids and enzymes producing large amounts of spent fungal biomass.

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

Improvisatoren in experimentele muziek leggen hun muziek niet vast in een conventionele partituur, maar in continu veranderende ‘tactiele paden’. Dit stelt onderzoeker Christopher Williams. Promotie 13 december.

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

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

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

Possible improvements for the assessment of abiotic depletion in LCA.

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

1. To what extent do metallic NPs added to soil extractions change the activity, abundance, or community composition of microbes? 2. How do the effects of metallic NPs on soil microbes differ from the effects of the ions shedding from corresponding NPs?
