The probability for dissociation of molecules on metal surfaces, which often controls the rate of industrially important catalytic processes, can depend strongly on how energy is partitioned in the incident molecule. There are many example systems where the addition of vibrational energy promotes reaction…

Graphene, the ultra-thin wonder material just a single carbon atom in thickness, holds the promise of such impressive applications as wear-resistant, friction-free coatings. But first manufacturers have to be able to produce large sheets of graphene under precisely controlled conditions. Dirk van Baarle…

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

What is the iconography of propaganda specifically as it relates to the historical development of political ideologies in modern Egypt and how was/is this propaganda disseminated among creative fields such as cinema, art, monuments, architecture, and literature?

The sixth issue of Ex Novo explores how ‘peripheral’ regions currently approach both the practice and theory of public archaeology placing particular emphasis on usually underrepresented regions of Eastern and Central Europe, the Mediterranean and beyond.

How was FDR's image constructed—by himself and others—as such a powerful icon in American memory?

Before 1936, musical practices in Palestine relied heavily on colloquial poetry, especially in rural communities, which constituted most of the population. In this dissertation, Issa Boulos has examined historical records that revealed many differences and similarities between Palestinian communities…

Much of the work of Serge Fehr, Professor of Quantum Information Theory, is abstract and theoretical and comprehensible to very few people. But his work helps make the digital world safer so that in future our internet banking will still be problem free, for instance. He will explain more in his inaugural…

Public sector decision-makers operate amidst an abundance of information and unclear political objectives. Attention is the sine qua non of policy-making: What is attended to can be addressed in policy responses; what is overlooked or goes unnoticed cannot. Despite its importance, public administration…

Theoretical research does not always give us the right solution to a problem in society. This message, loud and clear, is delivered during the final presentations of the Master Honours Class 'Social Innovation in Action'.

The main case study of the project is the cultural geography of Saqqara, the necropolis of the ancient Egyptian city of Memphis, and its development.

Video interview with Subodh Patil, the new assistant professor in Theoretical Cosmology, about the gravitational waves, hidden universes, music, and whether Dutch, Danish and German fit into one brain.

This political theory specialisation focuses on the concepts of legitimacy and justice—political philosophy’s core themes. Immersing yourself in theories, philosophical and theoretical methods, and complex cases, you will make the leap from opinion to analysis.

We are living through an age in which social media platforms have given way to entirely new forms of politics and politicking. It is no exaggeration to say: there is a before and after social media.

The bi-annual interactive seminars of the Platform for Postcolonial Readings are all about sharing our enthusiasm about our field of research and our eagerness to learn more about its theoretical intricacies. Our seminars, although informal, adopt a well-defined format. Each meeting is organized around…
