A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.

As leading cause of death worldwide, cancer is responsible for nearly 10 million deaths in 2020 according to World Health Organization (WHO). Cisplatin and its derivatives are commonly used chemotherapy agents for current cancer treatment in the clinics.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

This dissertation presents new cryptographic protocols, which can be divided into two families.

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

Op 21 oktober 2021 verdedigde Frederik Behre het proefschrift 'A European Ministry of Finance?'. Het promotieonderzoek is begeleid door promotor prof.dr. S.C.G. Van den Bogaert.

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…

Producing green energy has become the main goal in our society in the search of reducing or eliminating the carbon emission from fossil fuels.

Solar energy harnessed by plants and algae has great potential to be converted into biofuels for future generations.

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…

Supramolecular polymers are class of materials that are formed by non-covalent interactions such as hydrogen bonding, π-π interactions, electrostatic interactions and the hydrophobic effect.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

This thesis is a collection of experimental attempts to enhance photoluminescence of fluorescent molecules and quantum dots with single gold nanorods (GNRs) and relevant applications.

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

Microscopic insight on lipid-based nanomedicine in vivo remains limited to the perception of the knowledge that could be obtained: if we interpret only what we see, then we only believe to know. Although believing to know encapsulates an undefined amount of uncertainty in the exploration of lipid-based…

In my research, I used a comparative wood anatomical approach to address wood evolution of the (largely) tropical flowering plant families Apocynaceae and Sapotaceae.

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

Sound is everywhere in the marine environment and hearing is therefore a very important for stimuli for fish. They use sound for orientation and communication, during migration, aggregation and spawning, but also for detection of prey and predators.

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

De afdeling Environmental Biology (CML-EB) houdt zich bezig met vraagstukken rondom biodiversiteit en natuurlijke hulpbronnen op het platteland in westerse en niet-westerse gebieden.

This thesis focuses on developing wafer-scale two-dimensional (2D) materials by combining synthesis, transfer, characterization, and device integration of graphene, hexagonal boron nitride (h-BN), and BN-doped amorphous carbon.

This collection of papers was compiled in celebration of the remarkable academic career of Professor Wil Roebroeks, who has established himself as one of Europe’s leading figures in Palaeolithic archaeology over the past three decades and founded the Human origins research group at Leiden University…

De Leidse promovendus Xuequan Zhou heeft een veelbelovend nieuw molecuul ontworpen dat effectief kankercellen kan bestrijden zonder hierbij ook de gezonde cellen aan te tasten. De truc: het medicijn wordt pas actief als je het bestraalt met licht. Zhou’s nieuwe molecuul is extra efficiënt, aangezien…
