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.

The main focus of this thesis is the behaviour of two-dimensional materials, namely (anti)-ferromagnetic materials in the first two chapters, which show topological phases, and energetic square ice in the third and fourth chapter.

The research described in this thesis focused on the preparation of S/N functionalized carbene ligands and their transition metal complexes, and the exploration of their application as electrocatalysts for proton reduction.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

This thesis focuses on the synthesis, characterization and performance towards CO2 electroreduction of mono and bi-metallic particles based on p-block metals

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

‘De prikkels in de wetenschap zijn net zo pervers als bij de banken’, vindt UMC-bestuurder en immunoloog Frank Miedema. Staan andere belangen goed wetenschappelijk onderzoek inderdaad in de weg? Op maandag 24 maart geeft prof. Miedema een openbare lezing over ‘Science in Transition’.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

In the early universe, the dynamics of the Higgs field can give rise to many interesting phenomena.

Using the principles of Industrial Ecology in Environmental Policy making in two cases: transition to a hydrogen economy and chlorinated compounds.

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

Cryogenic electron microscopy (cryo-EM) is a powerful technique used to visualize the inside of cells and to study specific protein complexes. Within this thesis, I describe the use of various cryo-EM techniques to gain insight into the structural changes of the human pathogen, Vibrio cholerae, as it…

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

Om windturbines en elektrische auto’s te bouwen, hebben we tonnen magneten nodig. Momenteel importeren we die voornamelijk uit China, waardoor Europa voor de energietransitie erg afhankelijk is van deze grootmacht. Daar moet verandering in komen, aldus Industrieel ecoloog René Kleijn. In het project…

In the last decade, the redox interconversion between metal thiolate and disulfide compounds has been extensively investigated for copper, but not for other transition metal ions.

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.

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.
