Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.
In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.

Postdoctoral Position
“Modelling the gas separation performances of MOFs and their composites”
Position for 1 or 2 years - Starting Date: To be discussed
Keywords: Mixed matrix membranes, Metal-Organic Frameworks, Polymers, Gas Permeability, Gas mixture selectivity, Molecular Dynamics
Membranes offer great potential for the separation of most of the gas mixtures mentioned above. Namely, Inorganic-based and organic polymeric membranes have been tested intensively for such targeted applications. The distinct requirements for a membrane in terms of gas permeability and selectivity to be viable for commercial use remain highly challenging. Despite the superior performance of membranes-based on purely crystalline materials like zeolites or MOFs, polymeric membranes dominate the commercial scene thanks to their easy processing and mechanical strength. However there is a need to develop optimized Mixed Matrix Membranes (MMMs) based on highly engineered inorganic/hybrid solids and polymers to combine the best of both worlds (easy manufacturing, high fluxes per unit volume and high selectivity through advanced tailoring) to break the so-called Robeson upper bound between selectivity and permeability that hampers advancements in pure polymeric membranes.
The objectives of this computational work are to (i) identify the best MOFs candidates for propylene/propane and ethylene/ethane separation, (ii) further combine them with an appropriate set of polymers to define optimum MOF/polymer membranes with high compatibility between the two constitutive components and (iii) assess the permeability and selectivity performances of the corresponding membranes. This will be performed by combining quantum and force field-based simulations (Monte Carlo and equilibrium/non-equilibrium Molecular Dynamics approaches omputational approach we aim to apply to MOF/polymer MMMs will be performed in tandem with a strong interactions with several groups world leaders in the field of MMMs.
Potential candidates should have a strong expertise in molecular simulations applied to material science and ideally to polymers.
