We investigate how radiation pressure can be used to influence the mechanical motion of a micro-mirror suspended from springs.

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).

Adopting a largely chronological approach, Gerrits links the historiography of post-war Europe and the major theoretical approaches to nationalism with analysis of key historical developments and events.

This perspective addresses four challenges facing theorists whose aim is to make quantitatively accurate predictions for reactions of molecules on metal surfaces, and suggests ways of meeting these challenges, focusing on dissociative chemisorption reactions of H2, N2, and CH4.

Theorists have recently made substantial progress in simulating reactive molecule-metal surface scattering but still face major challenges. The grand challenge is to develop an approach that enables accurate predictive calculations of reactions involving electronically excited states with potential…

In Quantum mechanics, particles can be in multiple positions simultaneously. Yet, when a measurement is made, the particle is found only in one place. Technology has come to a point where we may design experiments that will tell us how.

This book connects labour history, global history and the institutional or political history of international organisations.

Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…

The 2006 United Nations Convention on the Rights of Persons with Disabilities differs markedly from other forms of international human rights law: it not only protects the rights of individuals but also addresses interpersonal relations and social structures. How did the convention attain this broad…

In this paper, Sarah Giest and Bram Klievink highlight the effects of AI implementation on public sector innovation. This is explored by asking how AI-driven technologies in public decision-making in different organizational contexts impacts innovation in the role definition of bureaucrats.

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

MetaROR is an open peer review platform based on the publish–review-curate model and aims to improve the dissemination and evaluation of metaresearch.

The United Kingdom’s relationship with the European Union was supposed to be definitively settled several times during the past decade – yet it was not. The 2016 referendum brought about a surge in interest in legal questions, especially of EU law and international economic law. This presented scholars…

FAIR-ASSESS brings together researchers from five different Leiden faculties, as well as experts from outside the university. The project has been initiated by Andrei Poama and is being led by Josette Daemen.

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

Together with colleagues from the Stimson Center and in the framework of the Global Governance Innovation Network, Dr. Joris Larik has recently published the report

The research described in this thesis shows that hypercholesterolemia, a well-established risk factor for atherosclerosis, can impact skin lipid pool and barrier function already at young age. In the field of atherosclerosis, we showed that the small peptide Lyp-1 can be used as a targeting molecule…

How can party bans be justified? Which parties were banned in post-war Europe – and why? Do militant democracy instruments work? Is an international militant democracy concept in the making?

Big data promises to transform public decision-making for the better by making it more responsive to actual needs and policy effects. However, much recent work on big data in public decision-making assumes a rational view of decision-making, which has been much criticized in the public administration…

Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

The focus of the research lies in the approach of reducing, denying, or taking away essential elements of music making in order to let the musician become theatrical.

LUCIS is directed by Nathal Dessing, who is advised by a steering committee.
