Hoe helpen lipasen in Mycobacterium tuberculosis de bacterie te overleven, en kunnen we deze enzymen gebruiken als doelwit voor nieuwe antibiotica?

Nog altijd lukt het niet om alle kankerpatiënten van de juiste behandeling te voorzien. Oncode Accelerator wil daarom de manier waarop we kankerbehandelingen ontwikkelen innoveren: binnen het programma wordt de patiënt centraal gesteld. Universiteit Leiden en LUMC gaan hier samen met andere partijen…

Om goed onderbouwde besluiten over complexe onderwerpen zoals het klimaat, recht en gezondheid te kunnen nemen, zijn wetenschappelijke resultaten van groot belang. Maar wetenschappelijke resultaten bevatten altijd een mate van onzekerheid. Binnen het onderzoek Communicatie over onzekerheden wordt onderzocht…

Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites.

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.

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

Planets are formed in disks of gas and dust around young stars.

Carbon dioxide capture and utilization technologies are necessary to create a truly circular economy. The electrochemical reduction of carbon dioxide to formate is an appealing carbon utilization method as it can be performed at room temperature and pressure, it only requires two electrons, and it has…

Microscopic insight on lipid-based nanomedicine in vivo remains limited to the perception of the knowledge that could be obtained: if we interpret only what we see, then we only believe to know. Although believing to know encapsulates an undefined amount of uncertainty in the exploration of lipid-based…

Hydrogen fuel cells are expected to be pivotal in the energetic transition towards renewable energy sources such as solar and wind power. However, their industrial scalability is severely hindered by the high cost and degradation rate of platinum catalysts, one of their key components. Addressing this…

Neurodegenerative diseases pose a large medical and societal challenge. The etiology of these diseases is still poorly understood, which makes drug discovery for these diseases difficult.

Green hydrogen is produced via a process called water electrolysis. During electrolysis water is split into oxygen and hydrogen.

The overall theme of this thesis is to complement the electrochemical data acquired in fuel cell research with in situ X-ray photoelectron spectroscopy (XPS) and soft X-ray absorption spectroscopy (XAS).

Reducing greenhouse gas emissions is one of the most pressing challenges that humanity faces in the coming decades.

In this thesis, we study different curved single crystals because of the diversity of surface structures across their curvature.

The specialisation Science Communication and Society (SCS) concerns science communication in a broad sense. The program focuses on the link between science and society and covers knowledge and skills in the field of science communication.

Developing new medicines is one of modern science's most significant hurdles, a process marked by high costs, long timelines, and frequent failures of promising candidates.

This thesis investigates reactive interfaces in surface science across three domains: heterogeneous catalysis, environmental nanoplastics, and two-dimensional materials.

This thesis focuses on developing wafer-scale two-dimensional (2D) materials by combining synthesis, transfer, characterization, and device integration of graphene, hexagonal boron nitride (h-BN), and BN-doped amorphous carbon.

Climate change is one of the largest challenges faced by humanity. To combat this research into alternatives to fossil fuels is ongoing. Dihydrogen is considered a good alternative fuel, since its burning only forms water.
