Project details
The impact that climate change is having on the world’s ecosystems affects every one of us. Our capacity to grow food, to maintain clean and safe water supplies, and our ability to do this in a way that is sustainable, is dependent upon our understanding of how soil and water are affected by our changing weather.
The EcoSENSE research cluster (involving 5 PhD studentships) will develop new sensors for the accurate, sensitive and real-time monitoring of the health of water and soil systems. We will achieve this through an ambitious and exciting series of interconnected projects combining expertise in Materials Science, Chemistry, Geography and Computer Science, guided by input from key Industrial partners including MAST group Ltd and Severn Trent.
Project summary
Our current patented technology is based on the dual encapsulation of luminescent probes for the detection of anions into crosslinked hydrogels. In this approach, the diffusion rate of ions into the material is restricted by the relatively low exposed surface area of the hydrogel and can be affected by the materials physical properties.
In this PhD project, we will investigate methods to optimise ion transport rate by selecting the appropriate manufacturing technique (for example fibre spinning) and material to achieve high efficiency of the sensing device. As well as further developing the patented technology, this will build on our work demonstrating the synthesis of polymer particles with tuneable size and composition (Polym. Chem., 2022, 13, 4124-4135), and the encapsulation of polymer particles into electrospun fibres (Soft Matter, 2021, 17, 3775-3783). The effect of material structure and composition on the encapsulation of the probes and diffusion of the ions will be investigated. The specific ions and probes will be guided by collaboration within the EcoSENSE cluster.
The EcoSENSE research cluster will develop a new class of advanced sensing materials for the continuous analysis of the health of aquatic and terrestrial ecosystems. This is key for understanding how ecosystems function allowing us to respond to the current drivers of environmental change.
During this PhD project, you will acquire skills in polymer synthesis and nanofabrication methods for sensing materials. Also, you will use state-of-the-art facilities for the characterisation of the nanomaterials developed. Within the Polymer group, you will work with a multidisciplinary team with extensive experience in polymer processing, polymer chemistry and sensing materials.
