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…

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

The ongoing increase in antimicrobial resistance combined with the low discovery of novel antibiotics is a serious threat to our health care.

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

In de tweede helft van de negentiende eeuw groeide Amsterdam uit tot hoofdstad van Nederland. Maar zagen de negentiende-eeuwse Amsterdammers zichzelf ook als Nederlanders? Dit boek laat zien hoe dienstmeisjes en schoenmakers, winkeliers en schooljongens hun Nederlanderschap in het dagelijkse Amsterdamse…

The physical origin of the dozens of stellar-mass binaries, the mergers of which have been detected by the LIGO-Virgo-KAGRA collaboration via gravitational waves, is still unknown.

“Temminck’s Order” is the scientific biography of Coenraad Jacob Temminck (1778–1850), a Dutch naturalist and the first director of ’s Rijks Museum van Natuurlijke Historie in Leiden.

Sorghum (Sorghum bicolor) is a major cereal crop that millions of subsistence farmers in Sub-Saharan Africa (SSA) rely on. However, the scourging impact of the root parasitic weed Striga (Striga hermonthica, a.k.a. “witch-weed”) has remained a major constraint hampering the productivity of sorghum in…

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

Filamentous Actinobacteria, such as Streptomyces, produce a plethora of chemically diverse bioactive metabolites that have found applications across medicine, agriculture and biotechnology.

New drugs for use as tuberculosis (TB) treatment are needed due to the constrains of classical antibiotics against TB and the rise of antibiotic-resistant strains, making TB a harder and harder disease to treat.

Including modelling as part of software development appears to have various benefits.

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…

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

It is a common technique in global optimization with expensive black-box functions to learn a surrogate-model of the response function from past evaluations and use it to decide on the location of future evaluations.

Medewerkers en studenten van Leiden University College (LUC) werken in Den Haag samen met maatschappelijke partners via onderzoek, onderwijs, stages en vrijwilligerswerk, waardoor er sterke banden ontstaan die ook na het afstuderen blijven bestaan.

In een wereld waarin bacteriën steeds vaker resistent zijn tegen antibiotica, ging Emma van Groesen op zoek naar oplossingen. Deze maand promoveerde ze, na vier jaar onderzoek naar nieuwe varianten van het antibioticum vancomycine. Met succes.

Hoe verminderen we de uitstoot van CO2 in de industrie? De Leidse psychologen Emma ter Mors en Christine Boomsma onderzoeken de publieke perceptie en acceptatie rondom de afvang en opslag van koolstofdioxide. Dat doen zij voor het Europese onderzoeksprogramma ALIGN CCUS.

Op vrijdag 6 november 2015 ontvingen ruim honderd studenten hun certificaat voor het behalen van het Honours College. De afsluiting van het studieprogramma blijkt belangrijk voor toekomstige werk- en studiekeuzes en een professioneel netwerk. Ook de hoge mate van persoonlijke ontwikkeling kwam tijdens…

Hoe kan het dat vlinders van dezelfde vlindersoort verschillende patronen op hun vleugels hebben? Volgens onderzoekers Ben Wielstra en Emma Berdan, van het Institute of Biology Leiden (IBL), ligt het antwoord bij supergenen. Dit zijn stukken van een chromosoom met daarin veel genen die sterk aan elkaar…
