Cosmologists propose new way to form primordial black holes
What is dark matter? How do supermassive black holes form? ‘Primordial’ black holes might hold the answer to these long-standing questions. Leiden and Chinese cosmologists have identified a new way in which these hypothetical objects could be produced just after the Big Bang. Publication in Physical…

An overall picture: the environmental impacts of a new solar cell technology
A more efficient solar panel sounds great. But what if these new panels consume more toxic materials, or their production consumes a lot of energy? Leiden environmental scientists, together with colleagues from the Fraunhofer ISE, address this multifaceted question in a new publication in the prestigious…

Observing what cannot be observed: computational electrochemistry from carbon to hydrogen
In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

Scholarly Vices: A Longue Durée History
This project tries to explain the persistence of this cultural repertoire by zooming in on (1) interaction between idioms (cultural repertoires) available to scholars at certain points in time, (2) mechanisms that help transmit repertoires across time and place, and (3) rhetorical purposes for which…

Heterogenized molecular (pre)catalysts for water oxidation and oxygen reduction
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.

Highly Efficient Activation of HCl Dissociation on Au(111) via Rotational Preexcitation
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…
