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

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

Cardiovascular syndromes are the major cause of death in Western societies.

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

This thesis describes the development and optimization of the first molecular tools to study the enzyme PLA2G4E.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

My PhD project studies how the temporally sequential Hox gene expression is regulated during head-tail patterning of the frog embryo.

This thesis investigates reactive interfaces in surface science across three domains: heterogeneous catalysis, environmental nanoplastics, and two-dimensional materials.

Nucleoid associated proteins maintain the architecture of the bacterial chromosome and regulate gene expression, hinting that their role as transcription factors may involve local three-dimensional chromosome re-modelling.

This work describes several studies into the electroreduction of carbon dioxide (CO2RR), both regarding mechanistical aspects and catalyst stability considerations. Mechanistic insights into carbon-carbon bond formation on a silver catalyst are described in Ch 2, were we find an acetaldehyde-like surface…

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.

Welke planten in de Mediterrane tuin waren al bekend bij de oude Grieken en Romeinen, en hoe werden ze toegepast?

Humans can see the world through the eyes of other humans and imagine what they know, want, and intend. This competence is known as Theory of Mind.

Na het ontvangen van je diploma van LUC, kun je als alumni overal ter wereld heen. Velen die je voor zijn gegaan hebben ervoor gekozen om een master als vervolgopleiding te doen. Sommigen beginnen meteen aan hun professionele carrière of volgen een PhD. Door de vele academische vakgebieden die op LUC…

NASA’s telescoop SOFIA geeft een nieuw kijkje in de chemie nabij jonge sterren: de geboorteplaats van nieuwe planeten. De Leidse promovendus Andrew Barr schrijft erover in de Astrophysical Journal. Hij en zijn collega’s vonden enorme hoeveelheden water en organische moleculen in de wervelende, schijfvormige…

Zet een plant in de vensterbank en hij zal binnen enkele uren naar het licht gegroeid zijn. Voor het eerst is dit mechanisme in planten op moleculair niveau in kaart gebracht door Leidse biologen en onderzoekers uit Gent en Lausanne. Ze publiceerden hierover in het prestigieuze Nature Cell Biology.

This thesis focuses on addressing four research problems in designing embedded streaming systems.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

In this thesis, the discovery and optimization is described of chemical tools to study the N-acylethanolamine (NAE) biosynthetic pathway.

In the thesis the dynamics of strategies is studied from two perspectives.In the first part of the thesis strategies are considered to be opinions present in a community.

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

The Vallesian, 11.1-9 Ma, was a special time in the Vallès-Penedes basin near Barcelona, where a biodiversity hotspot existed. Europe had a subtropical climate, with rhinos, forest giraffes, lions, hyenas, flying squirrels and primates.

Hospital pharmacies face significant challenges: the demand for sterile drug reconstitutions is increasing, while specialized personnel remain scarce. Automation offers a potential solution, but its practical implementation in hospitals is still unclear.

In Nederland bieden ongeveer 130 van de 700 middelbare scholen een tweetalige stroom aan. Toch is er nog maar weinig wetenschappelijk onderzoek naar CLIL (content and language integrated learning). Met haar proefschrift wil Evelyn van Kampen (promovendus bij het ICLON) bijdragen aan een beter begrip…
