Two open PhD positions in Soft Matter Nanomaterial Science:
Bijel templated membranes for molecular separations: Structure, selectivity, and transport phenomena.
Van’t Hoff Laboratory for Physical and Colloid Chemistry
Debye Institute of Nanomaterials Science
All current membranes employed for water treatment, gas separations, or chemical purifications are fundamentally limited in their throughput. Nanomaterials are promising candidates to increase the effective permeability of membranes, with potentials to reduce the energy and investment costs for molecular separations. The objective of this PhD project is to increase the effective permeability of membranes by increasing the specific surface area. We plan to accomplish this within a recently discovered nanomaterial named bijel. Bijels can have up to 1000 times higher surface areas compared to state-of-the-art membranes, making them highly interesting for separation technologies. Such practical implementation of bijels requires detailed understanding of their structural-, mechanical-, and transport properties. In this project, molecular separations within bijels will be realized in 3 steps: (a) The architecture and mechanical properties of bijels will be tailored to overcome diffusion limited transport in the membrane, (b) ultrathin polymer layers will be generated by interfacial polymerization, (c) the interplay of convection, diffusion and permeation will be quantified based on a combination of confocal laser scanning microscopy and computer simulations. The results from this project will enhance the understanding of fluid transport in porous materials and introduce a technology to overcome limitations of state-of-the-art membranes.
We are looking for two highly motivated PhD candidates with MSc degrees in physics, chemical engineering, chemistry, or material science. The ideal candidates have theoretical knowledge of transport phenomena/physical chemistry, simulation experience with COMSOL Multiphysics or a similar software, as well as laboratory experience in nanomaterial synthesis, characterization and microfluidics. However, also excellent candidates of other backgrounds will be considered. Besides the research responsibilities, the PhD positions also entail teaching assistance in physical chemistry and transport phenomena.
The first open PhD position is planned to be filled early 2021 and the second position in the summer/fall of 2021. The application deadline for the 1st PhD position is November 30th , 2020 and for the 2nd PhD position February 28th 2021.
