The evolution of Chinese industrial CO2 emissions 2000–2050: A review and meta-analysis of historical drivers, projections and policy goals
The emissions of the Chinese industrial sector alone comprise 24.1% of global emissions (7.8 GtCyr−1 in 2015). This makes Chinese industrial emissions of unique national and international relevance in climate policy. This study reports a literature survey that quantitatively describes the evolution…

Structure dependence of molecular reactions on surfaces
The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

Nanoparticle – redox protein biohybrids
Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

Dissociative chemisorption on transition metal surfaces
The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

Sjoert van Velzen receives Vidi grant to solve 'riddles from the universe'
Minuscule elementary particles from space colliding with Earth can give us an insight into the distant objects they come from. But first, you need to know how to catch them. With a Vidi grant from NWO, researcher Sjoert van Velzen will 'hunt' for neutrinos coming from exploding black holes.

Plant-based diet can help unlock technology to harness huge CO2 removal
Bioenergy with carbon capture and storage (BECCS) is a promising method for removing carbon dioxide (CO2) from the atmosphere and simultaneously generating energy. Yet this method is controversial, as it may require a great deal of land and water. Researchers at Leiden University have now proposed a…

The formation of complex organic molecules in dense clouds-Sweet results from laboratory
Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Focal-plane wavefront sensors for direct exoplanet imaging: Theory, simulations and on-sky demonstrations
One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…
