Biofouling, the growth of biofilms and the settlement of various living organisms, is a significant issue for industrial applications. This phenomenon affects all open cooling systems and can lead to negative consequences such as reduced efficiency and blockages in cooling pipes. Conventional methods to prevent biofouling involve the use of hypochlorite, biocides and algaecides, which are limited in use, along with environmental concerns regarding toxic by-products. Decades of contamination have degraded water related ecosystems and can contribute to water scarcity caused by climate change. This project aligns with the UN sustainable development goal 6, which aims to ensure clean water and sanitation for all. Moreover, by improving the efficiency of industrial processes, the project underpins the UK’s Net Zero strategy for decarbonising all sectors by 2050.
The application of nanomaterials is a promising method for preventing biofouling. Nanomaterials have unique physical, chemical and electronic properties in comparison to bulk materials. This is due to their large surface to volume ratio and size, shape and composition. The addition of antimicrobial metals such as copper and zinc into these nanomaterials have shown significant promise in mitigating biofouling. Within our lab, we have developed several nanomaterial platforms that have shown good efficacy in reducing biofouling. The aim of this project is to develop antimicrobial nanomaterial to remove microbial and environmental contaminants from water systems. The nanomaterials will be fabricated, characterised and analysed for their efficacy in preventing biofouling in laboratory and simulated field tests.
This is a highly interdisciplinary project that sits at the interface between materials sciences and microbiology. The student will have the opportunity to attend the Doctoral Training and University-run courses in relevant subject areas, as well as to interact with students and postdoctoral researchers from a wide range of scientific backgrounds. Extensive training will be provided throughout the project as part of internationally renowned research teams. The studentship will provide the candidate with a wide range of skills in basic science and translation that will strategically position them for a career in several different sectors.
The successful candidate should have, or expect to have, at least a 2:1 degree or equivalent in Chemistry, Materials Science, Chemical Engineering, Physics, or closely related subject. For informal enquiries, please contact Professor Raechelle D’Sa ([Email Address Removed])
