Research Interests
Professor Wang’s research focuses on new functional ceramics, electroceramic and composite materials that are inevitably required for the next generation of energy generation and storage, electronics and healthcare. His research group has been working on novel fabrication techniques for these materials and understanding of the correlations between their structural parameters, at various length scales ranging from molecular, nanometer to micrometer ranges, and their functional properties.
More recently, Professor Wang’s research is concentrating on carbon-based materials, nanohybrids and mesoporous materials for energy generation, energy storage and biomedical applications. He and his research group have successfully developed several types of new nanohybrids and mesoporous materials for applications in energy generation storage and drug delivery.
