In a study just published in the renowned journal Advanced Functional Materials, a team of American and Dutch researchers present design strategies for adjusting the thermal expansion behaviour of microporous Metal-Organic Frameworks (MOFs). In particular, the ability to realise negative thermal expansion coefficients is of great relevance to the potential application of MOFs – for instance at material interfaces where they could prevent cracking and peeling. Dr David Dubbeldam and Dr Jurn Heinen of the University of Amsterdam’s Van ‘t Hoff Institute for Molecular Sciences (HIMS) contributed to the research, that included both experimental work and computer simulation.
