Understanding and controlling the flow behaviour of nano-particle suspensions is crucial to the processing of ceramics with nano-scale features. Interparticle forces influence the flow behaviour and depend upon the the adsorption of ions to the particle's surface. The proposed research investigates the effect of ion hydration and surface type on ion adsorption, the resulting attractive forces and suspension flow behaviour. The outcomes of the project have potential for significant increase in fundamental understanding of the relationship between ions, surfaces and forces. The benefits of this knowledge include producing nano-ceramics with improved properties and better understanding biopolymer behaviour.Read moreRead less

Summary
Fatigue degradation in lead-free piezoelectric ceramics: the key factor for successful industrial implementation. Many everyday devices, that is mobile phones, operate with lead-based ceramics, which can be hazardous; although there are promising lead-free materials, these show complex electric behaviour which can lead to structural damage and device failure. This project will define the degradation mechanisms so that reliable non-toxic ceramics can be designed.

Crack Propagation within Graded Interfaces. Functionally graded interfaces are a technologically new way of joining materials in a wide range of biomedical and industrial applications. The reduction in the interfacial stresses resulting from the graded interface increases the structural integrity of the component, however, existing models do not fully address issues of plasticity and cyclic fatigue to their fracture.

Functionally graded interfaces are a technologically new way of joining materials in a wide range of biomedical and industrial applications. The reduction in the interfacial stresses resulting from the graded interface increases the structural integrity of the component, however, existing models do not fully address issues of plasticity and cyclic fatigue to their fracture. The intention of this study is to investigate how modifications to the ductile reinforcement phase and how the cyclic loading influence crack extension within a graded interface. These results will assist in future design and prediction of the in-service lifetime of components containing gradient interfaces.Read moreRead less
