PhD Position in Engineering the Microstructure of Bacterial Cellulose for Sustainable Applications
We are seeking a PhD student to work on an interdisciplinary project that uses soft matter physics and material science concepts to develop the next generation of architected bacterial cellulose for fundamental and sustainable applications.
Pressing challenges in climate change require the development of the next generation of renewable materials addressing cooling, CO2 capture and energy production. Bacterial cellulose is a very promising material to be used in a sustainable future because it is purer than plant-extracted cellulose and it is produced in a sustainable way. While this material has already showed promising applications in food, tissue engineering and energy, a fundamental physical understanding of its structural formation, as well as robust processing methods to control its structure across scales, are still missing.
The goal of this project is to develop novel methods to engineer the structure of bacterial cellulose at different length scales (nm-mm) and make functional materials for sustainable applications. In particular, we will use the combination of bottom-up approaches (self-assembly and phase separation ) with top-down approaches (3D printing) to carefully control structural features at various length scales. We will then characterize a range of fascinating structure-function relationships of these biomaterials with various techniques. These include confocal microscopy, polarized optical microscopy, tensile tests and X-rays. Finally, at the end of the project, we will collaborate with the Digital Building Technologies lab at the Department of Architecture at ETH to explore innovative integrations of biofabricated materials and sustainable buildings.
