Functional materials can convert one form of energy to another and thereby achieve an intelligent action as sensors or actuators, which are recognized as a vital area for the growth of the nation's economy. Our work is mainly concentrated on the interaction amongst synthesis, microstructure and polarisation-related properties of functional materials. Applied areas of interest are in sensors, transducers, actuators, microwave components used in telecommunication and information technology, and smart devices for renewable energy. On the fundamental side, we develop multidisciplinary expertise in wet chemical synthesis, crystal chemistry, defect chemistry, physical property characterisation, and modelling of functional materials. She has very close collaboration with Prof. Ray Withers.

Our initial aim in this project is to explore the origin of polarisation of microwave dielectric ceramics by means of crystal chemistry and defect chemistry, and thereby control and optimize associated dielectric properties.

The polarisation property of dielectric relaxors and ferroelectric relaxors presents a strong dependence on external fields (incl. temperature, electrical field and mechanical force even magnetic field) which can generate amazing functionalities for developing smart devices.
Our aims are the synthesis, functionalisation and functional characterisation of "small" dielectric materials, such as TiO2, BaTiO3, Na0.5Bi0.5TiO3 and boron nitride nanotubes for use in "small" smart devices.
