The multidisciplinary Center for Molecular Modeling (CMM, http://molmod.ugent.be) is looking for a highly motivated post-doctoral researcher to perform state-of-the-art research in the field of advanced molecular simulations of guest-loaded nanoporous materials in the context of hybrid membrane technology for more efficient C2 and C3 separations. The prospective postdoc will work in the research unit of Prof. Van Speybroeck and Vanduyfhuys.
The research is situated within the framework of a CO2 Moonshot project entitled ‘Moonrise’ in collaboration with partners from KULeuven, VUB and an industrial advisory board. The general aim of Moonrise is to create an energy-efficient alternative for cryogenic distillation in the production of C2 and C3 base chemicals by developing membranes for C2 and C3 olefin/paraffin separations. In addition, a membrane-based separation of these olefins from N2 will be targeted to drastically reduce olefin losses via flaring. Three different membrane types will be developed: polymer-only, mixed matrix membranes (MMMs) and metal-organic frameworks (MOF)-only. Through collaboration within a highly complementary consortium, this project joins various fields of expertise: membrane development, MOF-film preparation, diffusion and sorption studies, and molecular modelling. The CMM participates in the project as modeling partner with various research positions, who will study the modeling of diffusion/sorption properties will steer the material selection and optimization, while additionally helping to fundamentally understand the performances of the prepared membranes.
Molecular simulations have become an indispensable tool for the development of new application-oriented materials as they start from the interactions at a molecular scale and allow to efficiently compute thermodynamic equilibrium properties such adsorption isotherms as well as dynamic properties such as diffusion constants. In order to perform such simulations, an appropriate level of theory is required to describe the inter- and intramolecular interactions. On the one hand, a full quantum mechanical description is very accurate but not always feasible for large systems. On the other hand, force fields can provide the desired trade-off between accuracy and computational feasibility, provided they are well parameterized. Within this project both routes will be explored. Various static quantum calculations will be performed using density functional theory, post HF and/or the random phase approximation to get accurate estimates of the adsorption affinity of various sorbates in MOFs and polymer materials. Furthermore, new force fields will be developed to accurately describe the relevant host-sorbate interactions using existing in-house methodologies. As such, we aim to complement experimental characterization performed by our experimental partners to rationalize why certain materials subject in the Moonrise project perform well under a given set of conditions and guide the synthesis of new high-performance materials.
The prospective candidate will join a strongly connected research team and benefit from the experience present in the Center for Molecular Modeling (CMM), specifically on performing high-level quantum mechanical calculations as well as on force field development. He/she will collaborate with national and international academic partners and take an active role in the frequent meetings of the Moonshot project. The candidate can also take an active role in guiding PhD students working within this project. The CMM, headed by Prof. Van Speybroeck, is a multidisciplinary research center, which groups about 40 researchers of the faculties of Science and Engineering and Architecture with molecular modeling interests. The CMM aims to model molecules, materials and processes at the nanoscale by bringing together physicists, chemists, (bio-)engineers and stimulating collaborations across disciplines. Within the CMM collaborative research between researchers with various backgrounds and from various departments is pursued. This multidisciplinary collaborative mission is the DNA of the CMM and key to achieve scientific excellence in the field of molecular modeling.
