Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

An international team of astronomers has revealed the first 'chemical profile' of an exoplanet's atmosphere. The team, including Leiden astronomer Yamila Miguel and provenda Amy Louca, made the profile using so-called Early Release Science data from the James Webb Space Telescope. The results have been…

If we want to solve global problems, we need to know about both the theory and the practice. How does the international community make decisions about military intervention, for instance? Why is it such a complex process? Professor Herman Schaper has represented the Netherlands at the United Nations…

The Dick Stufkens Prize 2018 for the best PhD thesis of the Holland Research School of Molecular Chemistry (HRSMC) will be awarded to Dr Stefan Vuckovic. In his thesis, Vuckovic presents a new and innovative approach to the quantum mechanical calculation of atomic and molecular energies. It lays the…

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.
