Title: Stimuli responsive pores towards gated membranes based on iris-like nano-valves Research institute: Institute for Frontier Materials www.deakin.edu.au/ifm Institution: Deakin University Supervisors: Prof Lingxue Kong lingxue.kong@deakin.edu.au Dr Ludovic Dumee ludovic.dumee@deakin.edu.au Project description: This project aims at developing membranes with controllable gate-keepers at the site of the entrance of the pores. Stimuli responsive materials will be anchored and grafted across the surface of the pores to facilitate the constriction or expansion of the pores and thus act as nano-valves, allowing for selective diffusion based on bio-sensors feedback for adsorbed compounds strategically across the surface of the membranes. The strategy will be focused on the design of iris shaped polymers able to open/shut based on specific light or electrical stimuli. The iris, bio-mimicking an eye iris, will allow for selective diffusion based on the feedback from the sensing unit implemented within the membrane surface. The recent design of light- and electrically responsive polymers and their integration has paved the way for the implementation into complex 3D architectures and will be utilized as a base for this project. The project will tackle fundamental challenges related to: (i) the iris design and shape etching from responsive polymers, (ii) the implementation of biosensors across the surface of membranes and (iii) the reactivity of the nano-valve. The potential of such an approach will be primarily in analytical chemistry and highly selective membranes and find applications in ultralow trace contaminant removal, quality control and system protection and advanced nano-fluidics. The applications will span beyond the sole scope of the application tested in analytical chemistry, drug delivery and in bio-security where selectivity is prime to performance. The opportunities to develop more efficient separation systems will stem from this approach and be useful in a myriad of fields. Eligibility criteria · ‘Applicants must meet Deakin's PhD entry requirements, be enrolling full time and hold an Honours degree (First Class) or an equivalent standard Master's degree with a substantial research component. Please refer to the entry pathways to higher degrees by research for further information.’ · The PhD position is suited for candidates with background in computational materials science. · Language requirement: IELTS 6.5 发自小木虫IOS客户端 |
