Region of Research

  From a viewpoint of the energy saving and environmental problem solutions, the research fields of this department focus on both of the effective reuse of resources and energy including renewable ones and reduction of life hazardous materials and air pollutions. In particular, by controlling the interfacial mechanics and high-performance of materials, atomic/nano-scale composite materials and processing designs for the environmentally benign are established, and applied to innovative industrial development.

Current Research Subjects

  1. Titanium materials with high-strength and ductility via atomic-scale microstructure optimization by fi rst principle calculation
  2. Nano-carbon materials reinforced metal matrix composites through interfacial mechanics
  3. Surface modifi cation by 3D-nano structuring and application to novel biomaterials
  4. Direct bonding of plastic materials to metals by molecular structure control
  5. Nano-porous structured silica materials originated from rice husks
  6. Ni-rich TiNi shape memory alloys with nano-precipitation and expansion ability evaluation in application to stent devices
