  • Ultra-low Friction Technology Area

    Major fuel efficiency improvement through optimized lubrication technology at nano-interfaces

    Friction-reducing technology plays an important role in energy efficiency in automobile engines and many other mechanical systems (e.g. friction losses in automobiles amount to 20% of the total energy loss).

    In this technological area, practical low-friction materials and interface design technologies are developed in collaboration between Tohoku University and private industries by using Tohoku University's leading material-development technology, nano-interface evaluation and quantum mechanics simulator.

  • Ultra-low Core Loss Magnetic Material Technology Area

    Power transfer loss control and large scale energy loss reduction through ultra-high efficiency nano-crystalline soft magnetic material

    Today, magnet steel sheets which are largely used as magnet material in transformers and motors have reached their limits of improvement, thus making further reduction of energy loss difficult. Core loss of transformers and motors amounts to 3 per cent of the total electric energy consumption.

    In this project, we employ nano-crystalline soft magnetic materials discovered by Tohoku University and replace magnetic materials in transformers used for power transfer with this new material and thus aim to minimize power transfer loss.

  • High Efficiency Rare Elements Extraction Technology Area

    Implementation of metal cycles through optimization of collection and recycle technology of rare metals from urban mines

    Japan, which depends in its supply of rare earth and other rare metals on imports, faces a severe supply deficit caused by a global increase in demand and export controls by resource-rich countries. However, Japan possesses one of the worlds 'urban mines' (usable metals in processes products suitable for use as minerals).

    In this project we employ the strength potential of the Tohoku region in the metal and refining areas and establish research on metal cycles. As such, we attempt to optimize technology for collection and recycling of rare metals from 'urban mines', and aim at contributing to the solution of resource related problems.
