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

Het boek gaat in op de vraag: Hoe en waarom raken mensen betrokken bij het Europese 'homegrown jihadisme'?

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…

Trigonostemon Blume is a plant genus in the family Euphorbiaceae comprising 59 species.

Piepkleine plasticdeeltjes: we vinden ze tegenwoordig overal, van de diepten van de oceaan tot op de top van bergen. In de bodem, in planten, dieren en zelfs in ons lichaam. De vraag is: zijn deze deeltjes schadelijk, en zo ja: hoe? Op wetenschapsplatform The Conversation bespreken milieuwetenschapper…

De minor Creative Strategies for a Society in Change (CSSC) legt een verbinding tussen het verkrijgen van inzicht in creatieve maakprocessen en het verkennen van maatschappelijke problematieken die kenmerkend zijn voor onze tijd.

Onze promovenda Maral Darouei heeft in samenwerking met haar dagelijkse begeleider Helen Pluut een artikel gepubliceerd in het tijdschrift Career Development International (5-year IF = 2.704). Het paper is getiteld “The paradox of being on the glass cliff: Why do women accept risky leadership positions”.…

Surface acoustic waves (SAWs) are mechanical waves that travel along the surface of a material and find many applications in modern technologies due to the ease of excitation on piezoelectric substrates via interdigital transducers (IDTs).

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

Almost three years after receiving her honorary doctorate, Dr Graça Machel returned to Leiden University. Over the course of two days she spoke with students, researchers, and other interested persons, about human rights – particularly those of women and children – in a world in which these are continually…

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.

In this dissertation, we work towards an experiment in which we aim to bring a micrometer sized magnet at the tip of a soft cantilever into a superposition.

Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

The zoo of detected exoplanets reveals both the uniqueness of our own Solar System and the complexity of planetary system formation, sparking fundamental questions about how planetary systems form and evolve.

De Grachtwacht doet onderzoek naar stadsnatuur en de impact van plastic op de natuur. Met onze clean-ups verzamelen we niet alleen afval, maar ook data. Zo proberen we de bron van het afval te achterhalen en de kraan aan wal dicht te draaien. Zo komt er structureel minder plastic in de gracht!

Like a mixture of oil and water, lipid membranes separate into two liquid phases.

This thesis pioneers diatom molecular identification and quantification through genome-scale methods, with four key aims: (i) reviewing DNA/RNA sequencing methods in aquatic biomonitoring to highlight their strengths and limitations;

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

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

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.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

A novel mathematical model describes spatial-temporal drug distribution within one or more brain units, which are cubic representations of a piece of brain tissue with brain capillaries at the edges.

The endophytic microbiota is a community of various microorganisms that reside in plant tissue. These microbes are known to promote plant health and resilience, and their members do not simply exist side by side.

Kantorowicz onderzoekt hoe genderstereotypen de perceptie van leiderschapscompetentie beïnvloeden bij verschillende soorten crises.

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…
