Climate change, depletion of natural resources, loss of natural and cultural landscapes, and many other (ecological) sustainability challenges urge us to (re)evaluate human interaction with the natural world. This renewed environmental consciousness has invigorated not only scientists working on effects…

De energietransitie zal ook de bouw van een grote hoeveelheid energiecentrales met zich meebrengen. Zulke bouwprojecten kan op weerstand van omwonenden stuiten. Universitair docent Bríd Walsh onderzocht hoe een lokale gemeenschap het beste kan worden betrokken bij zo’n bouwproject.

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

Hoe dacht men tijdens de Renaissance over seks? Den Hartog neemt je mee op een tocht vol vervreemding én herkenning, en laat je met een nieuwe blik kijken naar seksuele opvattingen van toen en nu.

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

Producing green energy has become the main goal in our society in the search of reducing or eliminating the carbon emission from fossil fuels.

Solar energy harnessed by plants and algae has great potential to be converted into biofuels for future generations.

In this thesis, we develop a novel technique called Optical Near-field Electron Microscopy (ONEM), which aims to combine the advantages of both optical and electron microscopy: the high resolution of electron microscopy and the low sample damage of optical microscopy.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

This thesis addresses the challenge of sustainable urban development by analyzing the interplay between green and grey infrastructure to optimize resource use and ecosystem services.

Sustainable energy from wind and solar is most readily available near the sea.

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.

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

Electrocatalysis allows for storing electricity or converting it into chemical bonds, producing chemical building blocks and fuels using renewable resources.

In the first part of this thesis we study the geometry of folding patterns.

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

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.

This PhD-thesis presents a study on micron-sized particles, so-called colloids. By controlling the chemical and physical properties of these particles, such as the interparticle interaction and the particles’ shape, colloids can act as building blocks that self-assembly into larger structures.

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…
