Abstract: There are provided systems and methods for pairwise graph querying, merging, and computing for account linking. A service provider may provide an account graph system to identify pairwise similarities between different accounts based on shared data that may be identified through one or more linking characteristics. When providing pairwise graph similarities, a service provider may receive a query identifying two or more accounts and/or an account with a parameter for graph exploration and querying. The service provider may utilize connection, link, or relationship graphs, queried and generated using a graph database, to determine pairwise similarities between the designated seed account and one or more selected accounts. The graph may include vertices for different queried data points and edges connecting such queries, where directionality of the edges or other vectors may be used to identify links or hops between accounts for data querying and exploration.

Abstract: Bulk assemblies are provided, which may have desirable photoluminescence quantum efficiencies. The bulk assemblies may include two or more metal halides, and a wide band gap organic network. The wide band gap organic network may include organic cations. The metal halides may be disposed in the wide band gap organic network. Light emitting composite materials also are provided.

Abstract: Provided are organic metal halide crystals having a 1D nanotube structure. The metal halide crystals may have a unit cell that includes two or more face-sharing metal halide dimers. The metal halide crystals also may include organic cations. Methods of forming metal halide crystals having a 1D nanotube structure also are provided.
