NIMS Materials Database
The NIMS Materials Database (MatNavi) aims to contribute to the development of new materials and the selection of materials. MatNavi includes Polymer DB (chemical structures, polymerization, processing, physical properties, NMR spectra, etc.), Inorganic MaterialDB (crystal structures, phase diagrams, physical properties, etc.), Metallic Material DB (density, elastic constants, creep characteristics, etc.) and Computational Electronic Structure DB (band structures obtained by first-principles calculations, etc). It also offers applications such as the Composite Design & Property Prediction System. If you register, you can search and browse various databases for free.
Materials data platform (DICE) introduced DICE account (common ID) from Jan 17, 2023 to make each service work together.
To use MatNavi service, "(1) DICE account user registration" and "(2) MatNavi usage application" are required. (Registration and Application Manual)
1. Users are, in principle, individuals who are belonging to an organization.
2. Register a user for a DICE account with an e-mail address provided by your organization.
3. If the domain name of your e-mail address is registered in our management list, you can continue to apply for MatNavi usage. (Please use a computer browser. Smartphones are not supported.)
* How to apply for a mail address domain (to be applied for by the domain administrator(s) of your organization)
* The List of Domain Registered Organizations
4. In case you can not do the domain name registration, by verifying yourself using eKYC you may temporarily be able to apply for MatNavi usage.
[Note] Account issued under the previous system (until Jan 16, 2023) cannot be used. Please register as a user again under the new system.

The Composite Design & Property Prediction System (CompoTherm) is an advanced simulation tool for searching for candidate composite materials with optimal thrermo-physicical properties and structures.
The Metal Segregation Prediction System (SurfSeg) is designed to simulate surface or interface segregation in the following four cases: surface segregation in film/substrate, surface segregation in dilute alloy system, interface segregation at film-substrate interface, and interface segregation at alloy-substrate interface.
Interface Bonding Prediction System (InerChemBond) is a system that predict of interface chemical bonding between metal oxide (AxOy) and metal (M) or alloy (MB dissolved in MA).
Scheduled system maintenance
Service may be unavailable every Wednesday from 18:00 to 20:00 (JST) due to scheduled system maintenance.
