Plasticspotters
The Grachtwacht (Canal Watch) conducts research on urban wildlife and the impact of plastic on nature. With our clean-ups, we not only collect waste, but also data. This way we try to find out the source of the waste and turn off the tap on shore. This way there is structurally less plastic in the c…

Which DNA is floating in the ditch?
You pour a scoop of ditch water in the DNA scanner, and voilà: you know exactly which plants and animals the ditch accommodates. Well, it is not that simple yet, but according to PhD candidate Kevin Beentjes, we can already use DNA techniques to monitor the quality of freshwater. For his PhD research,…

Exploring the Universe
Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

Two cum laude distinctions for storing renewable energy
Both Leon Jacobse and Thom Hersbach from Marc Koper's research group obtained their PhDs cum laude. They both investigated changes on the surface of a platinum electrode. Jacobse studied this at a positive voltage, Hersbach at a negative voltage. Platinum has the potential to convert renewable energy…

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…
