abyss and time: towards an emancipatory poetics of the tropics and critical autoethnographic practices of research within media art.
This doctoral project by artist and educator Luiz Zanotello engenders a postcolonial understanding of time, space and movement by means of artistic research methods. The project examines the contradictory effects of the abyssal line of thought within the tropics as a starting point.

Microscopy and Spectroscopy on Model Catalysts in Gas Environments
In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

Beyond Utopia: New politics, the politics of knowledge and the science fictional field of Japan
This project aims to uncover a series of sites of difference and innovation. In particular, it locates itself in two kinds of distancing: geo-cultural (ie. in the non-European space of Japan) and medial (ie. in innovative expressive media).

Criticism from doctors about current coronavirus policy
Criticism from doctors in the Netherlands about the policy to combat coronavirus is becoming louder. A letter raising their concerns was signed by one thousand doctors. It calls for a new debate on the current measures to deal with the crisis which were recently tightened. Supporters of the letter believe…

Parental criticism hurts: a glimpse inside the adolescent brain
It may seem as though adolescents do as they please, but they are more sensitive to their parents’ opinions than they would appear. The adolescent brain reacts strongly to parental criticism or praise. These are the results of a study by an interdisciplinary research group of psychologists and neuroscientists…

Towards chemically accurate simulation of molecule-surface reactions
This perspective addresses four challenges facing theorists whose aim is to make quantitatively accurate predictions for reactions of molecules on metal surfaces, and suggests ways of meeting these challenges, focusing on dissociative chemisorption reactions of H2, N2, and CH4.

Surface plasmon lasers
Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

Gas-surface reaction dynamics and surface science
The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…

Galaxy formation traced by heavy element pollution
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.

Reactivity of cobalt(II)-dichalcogenide complexes: correlation between redox conversion and ligand-field strength
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.

Adiabatic Energy Loss in Hyperthermal H Atom Collisions with Cu and Au: A Basis for Testing the Importance of Nonadiabatic Energy Loss
Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.

Nano-scale electronic structure of strongly correlated electron systems
In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

Modeling energy conversion dynamics at interfaces
Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface.
