We collect unique copies of all materials in the "Materials Bank" collection. The general features of a Bank are discussed in the following introductory page. We assert the uniqueness by structural parameters and the use of standard primitive representation 1.
Materials Mapping Function first calculates the standard primitive representation of the candidate structure. Next, the corresponding hash string is produced. The hash is then compared against those of existing Bank entries in the same manner as for other bank entries.
Advanced search functionality specific to Materials and available also for Materials Bank page are described here.
The procedure of copying (or importing) Bank Materials into Account-owned Materials collection is described here.
