In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

Alzheimer's disease (AD) is the most frequent neurodegenerative disorder and the primary cause of dementia. The neuropathological features of AD include the occurrence of senile plaques, neurofibrillary tangles, decreased synaptic density, and loss of neurons. An obstacle in the study and treatment…

In this thesis, we show how MRFM can usefully contribute to the field of condensed-matter.

Does the presence of Ring-necked parakeets negatively influence feeding and feeding behaviour of native bird species on artificial bird feeders and if so, what are possible solutions?

Zebrafish is an excellent model organism for studying various human diseases. Due to opaqueness of the adult phase, in vivo studies are restricted to early embryonic stages. This raises the need for rapid sensitive and non-invasive in vivo imaging methods to follow developmental processes, not only…

Over time Dutch and Indonesian composers, performers and music scholars have inspired each other and they continue to do so. The presence of the Dutch in the Netherlands East-Indies and Indonesia, but also the existence of large diasporic communities in the Netherlands have contributed to a mutual exchange…

SMR can be used to measure the mass of adsorbed protein to nanoparticles with a high precision in the presence of free protein.

A network combining 9 academic research groups and 4 collaborating industrial companies will train the next generation of PhD students and post-doctoral researchers, in developing and applying novel experimental and theoretical methods in the NMR spectroscopy of systems containing paramagnetic metals.…

Multi-channel sound and video installation of the on-going project: Decomposing Landscape (2014 -).

This thesis consists of two subjects, that are both a consequence of radiation pressure.

Researchers from Japan and the Netherlands who were previously involved in the discovery of an exoplanet with huge rings have now calculated that the giant rings may persist more than 100,000 years, as long as the rings orbit in the opposite direction to that of the planet around the star. Their findings…

Our group explores the larger domain of quantum measurement. In particular we investigate two themes that are closely connected: The detection of specially prepared quantum states of light and understanding and characterizing quantum photon detectors.

Astronomers from the Leiden Observatory and from the University of Rochester (in the US) have discovered that the planetary ring system that covered the very young sun-like star J1407 is actually of enormous proportions. In fact, it’s much larger and heavier than the ring system surrounding Saturn.…

Meticulous analysis of hundreds of photographic plates from the star J1407 between 1890 and 2007 show no stellar eclipses. Robin Mentel, a master student at Leiden University, could not detect eclipses of the star J1407 by a planet hypothesized to have giant rings, called J1407b. However, an eclipse…

You can still enroll for the master Magnetic Resonance Physics course. It starts at Monday, Nov. 13th 13:30 in HL 226. For more information go to https://studiegids.leidenuniv.nl/courses/show/76629/magnetic-resonance-physics

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

This thesis investigates the relations between metabolism and anatomy through the use of Magnetic Resonance Imaging (MRI).

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

Rare-earth materials are prime candidates for storing quantum information, because the undesirable interaction with their environment is extremely weak. Consequently however, this lack of interaction implies a very small response to light, making it hard to read and write data. Leiden physicists have…

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

The death of George Floyd at the hands of the police may have sparked the Black Lives Matter protests in the United States and here in the Netherlands, but they are about more than that alone. We asked Karwan Fatah-Black, a historian who specialises in the Dutch colonial history, for his analysis. ‘We…

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

Research groups in the Biological & Soft Matter Programme unravel mechanisms in biological processes and develop novel bio-inspired soft materials.

Assuming everywhere good reduction we generalize the class number formula of Taelman to Drinfeld modules over arbitrary coefficient rings.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

The recently introduced nature-originated deep eutectic solvents, so-called natural deep eutectic solvents (NADES) are considered as truly green solvents, which composed of natural ingredients found abundantly in organisms.

The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.

We investigate how radiation pressure can be used to influence the mechanical motion of a micro-mirror suspended from springs.

The indane (2,3-dihydro-1H-indene) ring system is an attractive scaffold for biologically active compounds due to the combination of aromatic and aliphatic properties fused together in one rigid system.

Dynamic nuclear polarization with paramagnetic agents can enhance nuclear magnetic resonance signals by orders of magnitude. The mechanism of enhancement depends a.o. on the magnetic resonance properties of the agents used. Electron spin relaxation times at NMR relevant magnetic field/microwave frequencies,…
