Current Research Topics

Our major research field is called "Tribology".Three major keywords in tribology are friction, wear and lubrication. In this research field, our laboratory focuses on boundary lubrication, and physical chemistry of lubricants

  • Studies on Boundary Friction.
  • Oxidative Degradation of ZnDTP and its Effect on Antiwear Characteristics of Engine Oils.
  • Studies on Space Tribology.
  • Elastohydrodynamic Lubrication and Rheology of Lubricating Oils under High Pressure.
  • Rheology of Grease etc.
