This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

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.

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…

The research in this thesis is focused on tomographic reconstruction based on two imaging modalities in electron microscopy.

This thesis concerns the relation bettween the good reduction of Shimura varieties and the associated loop groups.

One of the most important puzzles in modern astrophysics is the nature of dark matter.

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

The Economics and Governance specialisation of the Master in Public Administration teaches you to formulate problem-solving approaches to concrete policy issues found at the intersection between economics and public administration. This specialisation is a unique joint offering of the Department of…

Aan de Universiteit Leiden zijn ruim honderd specialisten werkzaam op het terrein van de Middeleeuwen en de Vroegmoderne Tijd. Met ingang van 2017-2018 bundelen zij hun krachten binnen twee keuzetrajecten – Medieval Studies en Early Modern Studies – beide te volgen vanuit bestaande masteropleidingen…

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 deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

En dan ben je afgestudeerd neerlandicus. Je beheerst het Nederlands uitstekend, zowel mondeling als schriftelijk. Bovendien ben je een onafhankelijke, kritische en creatieve denker die complexe zaken snel en adequaat kan analyseren. Dat maakt je geschikt voor veel verschillende functies.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

How did colonial law work to turn people into property? This project argues that colonial ideas about households and domestic authority were critical to legal processes of enslavement in the early modern Dutch empire. Using colonial court records from Dutch Brazil, Suriname, and the Moluccas, the project…

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

Has the industrial sector in China effectively been decarbonizing in recent years, across different regions and subsectors, and is it plausible that it will reduce its CO2 emissions in conformity with national and internationally pledged emission goals?

An Active Galactic Nucleus (AGN) is a highly luminous region at the center of a galaxy, powered by the accretion into a supermassive black hole and emitting energy from radio waves to gamma rays, often outshining the host galaxy.

In the last decade, the redox interconversion between metal thiolate and disulfide compounds has been extensively investigated for copper, but not for other transition metal ions.

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.

Sinds ruim vijftien jaar wordt er door de British-Kuwait Friendship Society jaarlijks een prijs uitgereikt voor een in het voorafgaande jaar verschenen studie over het Midden-Oosten. Remke Kruk, emiritus hoogleraar Arabisch, won de tweede prijs.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…

To an algebraic curve C over the complex numbers one can associate a non-negative integer g, the genus, as a measure of its complexity.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

Recently, a new edition of the ELS bulletin was sent out. Furthermore, we are thrilled to share the Midterm Report of the ELS lab @Leiden with you!
