Using 3D printing technology to develop architecturally-controlled synthetic bone substitutes. With the ageing population, there is increasing demand for synthetic materials that can regenerate bone. However, purely synthetic bone-substitute biomaterials cannot regenerate large bone defects in weight-bearing conditions due to their fragility.

With the ageing population, there is increasing demand for synthetic materials that can regenerate bone. However, purely synthetic bone-substitute biomaterials cannot regenerate large bone defects in weight-bearing conditions due to their fragility. This project aims to develop a customisable, biodegradable, biocompatible and mechanically strong and tough scaffold that overcomes this long-standing problem. The project aims to achieve this by applying an innovative combination of cutting-edge 3D printing technology, advanced computational modelling and design techniques to produce a next-generation bioceramic scaffold with optimised architecture. This approach aims also to enable the possibility of producing custom-made implants for individual requirements.Read moreRead less

Tailoring composite propellers for reduced sound radiation. This project aims to explore the generation of noise by composite propellers and to use this understanding to tailor the composite properties to reduce underwater noise. Propellers are a harmful source of noise in the marine environment, disturbing animal behaviour, revealing the location of naval vessels and interfering with sonar operation.

This project aims to explore the generation of noise by composite propellers and to use this understanding to tailor the composite properties to reduce underwater noise. Propellers are a harmful source of noise in the marine environment, disturbing animal behaviour, revealing the location of naval vessels and interfering with sonar operation. Adaptive composite propellers are potentially quieter than metal propellers, as well as offering improvements in efficiency and fuel consumption. The aims of this project are to understand the physical mechanisms associated with composite propeller noise generation. The outcomes are intended to provide advanced numerical capabilities that will support the development of quieter marine propeller designs to improve defence capability and the acoustic environment for marine mammals.Read moreRead less

A new biomechanical model for understanding aging of stored Red Blood Cells. This project plans to develop a novel modelling framework to accurately represent the biomechanical properties of red blood cells (RBCs) over time under stored conditions.

This project plans to develop a novel modelling framework to accurately represent the biomechanical properties of red blood cells (RBCs) over time under stored conditions. Stored RBCs suffer ageing-related deformability changes which impede RBC functions. The framework aims to integrate models for RBC membrane, inside haemoglobin and outside storage solution, and accounts for ageing effects by embedding time-dependent correlations. It should provide new insights and understanding of the mechanisms of deformability changes of RBCs during stored lifespan. Therefore, it should significantly improve blood storage industry practices in terms of improving RBC storage protocols with preventative ageing strategies.Read moreRead less
