Modeling energy conversion dynamics at interfaces
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,…

Rewriting Hellenism: André Chénier (1762-1794) and Hellenistic Poetry
The project focuses on an intriguing aspect of André Chénier’s poetry, which has not received much attention in scholarship: Chénier’s indebtedness – in the form of translation, adaptation, borrowing, reference – to Hellenistic poetry; it interprets the role of this indebtedness in his poetical and…

Persia and Babylonia: Creating a New Context for Understanding the Emergence of the First World Empire
The Persian Empire (539-330 BCE) was the first world empire in history. At its height, it united a territory stretching from present-day India to Libya - and it would take 2,000 years before significantly larger empires emerged in early modern Eurasia. This territorial sweep is both a source of fascination…

Superselective bonds light up
Rather than one key and one strong lock, biology often uses tens or hundreds of weaker links to bind parts together, such as cells membranes. This allows for selectivity and also reversibility: the binding can also be undone. Researchers first caught this phenomenon using spheres or colloids, and published…

New generation of graphene biosensors based on smooth surfaces and sharp edges
The surface and the edges of graphene are expected to provide higher sensitivity and specificity in detecting and characterizing single molecules. However fundamental physical limits exist in reaching an ultimate precision in detecting the dynamics of chemical and biological systems. The research in…

Materials made of self-spinning particles
Materials are either gas, liquid or solid, based on how their molecules respond to temperature and pressure. But what if the building blocks are self-spinning particles instead of ordinary molecules? Theoretical physicists found out what determines the phase of those artificial materials. Publication…

Cities in the Greek World
Whereas when we started the first Project the chief aim was pure research, to find out more about the past in a region, now we see that the countries of Europe are faced with the great problem that there are far too many archaeological sites for them to deal with by excavation, but yet some kind of…

Redox catalysis for a sustainable energy infrastructure
The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…

Chemistry between stars and planets
In the large gas clouds between the stars, chemical reactions take place under extreme conditions, giving rise to both small molecules, such as water and common salt, as well as large complex molecules that can serve as the building blocks of life. This is known as astrochemistry and it is something…
