Supramolecular polymers are class of materials that are formed by non-covalent interactions such as hydrogen bonding, π-π interactions, electrostatic interactions and the hydrophobic effect.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

We investigate bacteria and fungi to understand their malicious or beneficial impact on food crops and their pathogenic or antibiotic role in human health.

Animal species that are dear to us in the Netherlands often spend a large part or all of their lifecycle in other parts of the world. But their habitats worldwide are under increasing pressure, are often inadequately protected and much poorer than the global average. ‘If we truly care about these animals,…

In mid-March 2020, the European Commission adopted, against the background of the Corona pandemic, temporal common rules for the export into third countries of personal protective equipment, needed in the context of the Corona pandemic, out of the EU.

Research at the MCBIM group is comprised of the following research themes:

Many dangerous diseases such as COVID-19, Ebola and Q fever have jumped from animals to humans. But it is not only because of these diseases that we should include animals in our health policy, but also because of their right to health, writes PhD candidate Joachim Nieuwland. PhD defence on 13 May.
