Overview of Research and Education

Research Contents: Gels are biotissue-like soft, wet and deformable materials. The aim of our study is to create novel tough and functional gels, to investigate their toughening or functionalizing mechanism, and to apply our novel gels as artificial bio-substituting materials. Our research also aims to generalize the principles of novel tough gel development for other types of soft materials towards application in industrial fields.

Selected topics are listed below:
1) design and fabrication of tough gels and elastomers
2) Investigation of fracture mechanics and dynamics of soft materials
3) Synthesis of gels with low surface friction and investigation of their lubrication mechanism
4) Fabrication of tough and soft composites and investigation of the toughening mechanism
5) Mechanochemistry of gels
6) Fabrication fo soft ceramics through biomineralization
7) Biomaterials and artificial cartilage.
