The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

Seagrass is a marine flowering plant with special adaptations to coastal and marine environments, playing a crucial role in providing a wide range of ecosystem services.

Kidney transplantation is a major advance of modern medicine. This course will give you state of the art updates about what used to be an experimental, risky, and very limited treatment option more than 50 years ago and is now routinely performed in many countries worldwide.

Een sterrenstelsel kan groeien door gas uit zijn directe omgeving naar binnen te trekken. Maar astronomen weten nog niet precies hoe dit gebeurt. Sterrenkundige Joop Schaye gaat met een Europese onderzoekssubsidie van 1,5 miljoen euro op zoek naar antwoorden.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.

This thesis addresses the problem of designing performance and energy efficient embedded streaming systems, that is, systems which process a stream of input data coming from the environment and generate a stream of output data going into the environment.

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

Real-life processes are characterized by dynamics involving time. Examples are walking, sleeping, disease progress in medical treatment, and events in a workflow.

Hydrodesulfurization (HDS) is an ubiquitous part of oil refining that ensures that fuels are cleaned of impurities and environment release of pollutants such as SOx and NOx gasses are minimized.

Electron microscopy has become an extremely important techniquein a wide variety of elds.

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

Optical cavities are useful tools to enhance the interaction between light and matter, which is important to make good quantum emitters. However, it turns out that the cavities themselves (without any quantum emitters) are already interesting objects to study.

In this thesis we study products of linear error correcting codes.

This dissertation is a collection of four research articles devoted to the study of Kummer theory for commutative algebraic groups.

Op 23 juni 2020 verdedigde Santy Kouwagam haar proefschrift 'How lawyers win land conflicts for corporations: Legal Strategy and its influence on the Rule of Law in Indonesia'. Het promotieonderzoek is begeleid door promotoren prof.dr. A.W. Bedner en prof.dr. C.E. von Benda-Beckmann.

An objective of this research was to achieve direct, well-defined and non-rate-limiting electron transfer between respiratory enzymes and the electrode surface by means of 'Q-wires'.

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations.

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

Galaxies in the Universe are distributed along the intricate framework of the Cosmic Web. Groups and clusters of galaxies comprise the densest regions in this network, and therefore, are excellent cosmic laboratories to study different aspects of galaxy evolution in extreme environments.

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

Dankzij een slimme nieuwe techniek zijn Leidse astronomen er voor het eerst in geslaagd om de atmosfeer van een exoplaneet gedetailleerd te onderzoeken. De resultaten van hun onderzoek worden op 28 juni gepubliceerd in het tijdschrift Nature.

CML-IA is a database that contains characterisation factors for life cycle impact assessment (LCIA) and is easily read by the CMLCA software program.
