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…

Cost-effective catalyst converts CO2 into natural gas
A discovery made in Leiden helps not only to make natural gas from CO2 but also to store renewable energy. Research by Professor Marc Koper and PhD student Jing Shen shows how this process can be implemented in a cost-effective and controllable way. Nature Communications, 2 september 2015.

Biomimetic models of [NiFe] hydrogenase for electrocatalytic hydrogen evolution
The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

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.

Theoretical Physics
In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

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…
