Researchers led by Professor of Chemistry Marcellus Ubbink have recently published a study in Proceedings of the National Academy of Sciences (PNAS) about the dynamics of an important redox enzyme. This work was accomplished thanks to an NWO VICI subsidy granted to Professor Ubbink.

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

A 90+ seat room in the LUMC Main Building. Rolling, flexible, tables on a carpetted floor allows for the quiet re-arrangement of the room to support teaching in groups of many size. Nearly 3 full walls are covered in magnetized, writable surfaces, and there are hinged TVs on the walls which can be beamed…

Plant Sciences' contribution to the Evolution & Biodiversity research theme is to understand what are the key drivers of plant biodiversity during evolution with a focus on plant life history and resilience traits and develop tools to restore and maintain plant biodiversity.

Leiden physicist Maarten Kruithof has discovered how our DNA is infallibly able to fold itself and to unfold again. In his dissertation he demonstrates how DNA is folded in a single long, very flexible spiral.

The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…

The Paramagnetic NMR Facility Leiden has been established to provide support to researchers who want to apply paramagnetic NMR spectroscopy to biomolecules. Support is offered in the design and synthesis of paramagnetic probes, either for general application (such as lanthanide tags and spin labels)…

Current research at the Skin Barrier and Vaccination group.

This thesis covers various applications of topology in condensed matter physics and quantum information.

Our group operates at the cross-roads of different disciplines: molecular and cellular microbiology, biochemistry, structural biology and biophysics. The group harbors expertise in a multitude of molecular and cellular approaches including:

When does it rain when air is oversaturated with moisture? How does an infection spread among the population? The problems that mathematician Professor Frank den Hollander tries to solve come from physics, chemistry and biology.

1) Assess the trends in supply and production status of these critical minerals and mineral products worldwide and Europe’s dependence including on intermediate products such as permanent magnets, RE based super alloys, batteries, polishing compounds, phosphors, catalysts etc. 2) Trace the entire value…

Research groups in the Quantum Matter & Optics programme investigate electronic properties of matter and light-matter interactions with emphasis on quantum information.

Central in coordination and organometallic chemistry is the synthesis of new chelating ligands, the synthesis and characterization of metal complexes with these ligands, and the study of their properties. An important goal in my research is to create understanding of the relation between the structures…

Electrons that spin synchronously around their axis, turn out to stay superconducting across large distances within magnetic chromium dioxide. Electric current from these electrons can flip small magnets, and its superconducting version could form the basis for a hard drive without energy loss. Publication…

A new NMR microscope gives researchers an improved instrument to study fundamental physical processes. It also offers new possibilities for medical science, for example to better study proteins in Alzheimer patients’ brains. Publication in Physical Review Applied.
