Understanding platinum dissolution in biomedical stimulating electrodes. Platinum is the main material used in electrodes for neurostimulators like the cochlear implant. Platinum electrodes can experience dissolution during implantation, which can impact on their function. The mechanisms governing this dissolution process are complex and still not fully understood. This research aims to understand the chemical, electrical and biological factors that impact on platinum dissolution in electrodes. ....Understanding platinum dissolution in biomedical stimulating electrodes. Platinum is the main material used in electrodes for neurostimulators like the cochlear implant. Platinum electrodes can experience dissolution during implantation, which can impact on their function. The mechanisms governing this dissolution process are complex and still not fully understood. This research aims to understand the chemical, electrical and biological factors that impact on platinum dissolution in electrodes. It will also develop new 3D models to simulate conditions in the human body for more rapid testing of electrodes. The new knowledge generated will improve the accuracy of predictions of platinum dissolution, develop new approaches for minimising dissolution, and contribute to reducing need for animal experimentation.Read moreRead less
Identifying how cortical bone microstructure deteriorates with age. This project aims to define the disruptions responsible for the gradual weakening of the skeleton in ageing by integrating a range of high-resolution imaging, biomechanical, and computational methods. The expected significance of this project includes a full definition and comparison of the cellular and subcellular organisation of bone from young and elderly individuals. Expected outcomes of this international project include th ....Identifying how cortical bone microstructure deteriorates with age. This project aims to define the disruptions responsible for the gradual weakening of the skeleton in ageing by integrating a range of high-resolution imaging, biomechanical, and computational methods. The expected significance of this project includes a full definition and comparison of the cellular and subcellular organisation of bone from young and elderly individuals. Expected outcomes of this international project include the establishment of a new multidisciplinary research team, and the development of a new data-driven theoretical framework for understanding the nature and the causes of age-related bone fragility. Potential long-term benefits include new ways to treat age-related osteoporosis.Read moreRead less
