It is currently very difficult to control interfaces between semiconductors in photocatalysis. In this project, we will introduce a new technology in this area — 3D printing — in combination with directed assembly to create structures with controlled architecture at multiple scale lengths (from nm to cm) and to optimise interfacial properties. The scope is to address the limited availability of flexible bottom-up assembly approaches for inorganic and organic materials in water based systems. We will advance the field by designing versatile assemblers that can facilitate the water processability of new organic materials for step-change photocatalysis. This will be a lab-based PhD that will start with the modification of known pH-responsive surfactants. The second stage will deal with the design of new molecules capable of functionalizing other soluble organic polymers and inorganic colloids to make them responsive, facilitating a change in their aggregation and rheology. The use of automated platforms in the Materials Innovation Factory will provide a library of component molecules, which will be tested using stand-alone and high-throughput rheology. The establishment of a workflow between the two (automated synthesis and rheology measurements), combined with design of experiments tools, will enable identifying final candidates.
The studentship will be based in the Materials Innovation Factory (MIF), supervised by Dr Esther García-Tuñón (80%, MIF lecturer affiliated to the School of Engineering) and co-supervised by Prof. A. I. Cooper (20%, Chemistry/MIF). The studentship will be jointly funded between the School of Engineering and the Leverhulme Research Centre for Functional Materials Design, a new £10 M, 10-year activity funded by the Leverhulme Trust.
Qualifications: A 2:1 or higher degree or equivalent in Chemistry with a strong interest in directed assembly, or alternatively a strong interest in organic materials with Chemical Engineering background. The candidate will be expected to have strong chemistry background.
The applicant will be part of two research groups in the University of Liverpool. Further information can be found here: https://www.liverpool.ac.uk/engineering/staff/esther-garcia-tunon-blanca/ https://www.liverpool.ac.uk/cooper-group/research/
