Materials Database Group

JAPANESE

One of our missions is to make Materials Information Technology Station MTIS at NIMS a world-wide center of sending information, which ranges from the dimensions of atoms and molecules, through the nano-scopic- and metallographic sizes, to the scales of components, structures and social infrastructures.
Thus, our activity covers not only taking factual data but also those as follows:

• constructing materials databases with NIMS-original data,
• constructing metallograpy databases by applying unique know-how of experimental techniques,
• constructing literature databases with wide coverage and careful choice,
• designing and coding epoch-making engines and tools to analyze factual data with new ideas,
• establishing "distributed database" technologies to realize joint-ownerships and mutual

　

• developing knowledge (rule) base with higher intellectual value.
