An indian stepwell on a nanoscale. That is what postdoc Nakkiran Arulmozhi calls the pattern he saw when he corroded a special kind of platinum crystal. The unique images show the destructiveness of the process, but also show how predictable it is.

CML’s education programme aims at training (under)graduate and graduate students for integrated and multidisciplinary sustainability research and for better decision making in managing the world’s natural resources, environmental quality and biodiversity.

In the master’s programme in Archaeology, you can follow courses on the archaeology of Europe, deepening your understanding of the continent’s long history.

This research aims to fully recall these lost sound aspects of the eighteenth century and is, therefore, a study that passionately advocates the diversity of musical experience in the context of historical performance practice.

Throughout all domains of life, from bacteria and archaea to eukaryotes, genomes adopt well-organized three-dimensional structures that can change in space and time to accommodate preferred transcriptional programs for environmental adaptation, the maintenance of cellular identity and differentiation…

The chemical industry must continue to innovate for a more sustainable, healthier society. The reseachers from the Leiden Institute of Chemistry (LIC) contribute by applying their knowledge to themes such as sustainability, energy and health.

Research and education at the Leiden Institute of Chemistry is overseen by the Institute Board. The Board and representatives of the two research themes form the Management Team. The Scientific Council (WERA), the Institute Council (I-Raad) and the platform for PhDs and post-doctoral co-workers (LIC73)…

Earth and outer space have become increasingly intertwined environmentally, politically, and philosophically, as satellite constellations multiply, lunar activities expand, and aspirations for Mars and beyond gain momentum.

Using N2 dissociation on Ru(0001) as a representative showcase (for catalysts employed in the Haber-Bosch process), we have shown for the first time that non-adiabatic effects can substantially reduce a molecule’s dissociation probability on a metal surface. These effects are currently completely unaccounted…

The European FET-Horizon2020 LMCat project of Dr. Irene Groot has released a promotional video showing the role graphene could play in our daily lives, how LMCat's production technique works, and how the consortium is capable of taking graphene production to the next level.

The Dick Stufkens Prize 2019 for the best PhD thesis of the Holland Research School of Molecular Chemistry (HRSMC) will be awarded to Thom Hersbach.
