Patent number: 11993615Abstract: Tunable thermochromic materials comprise a metal salt with a varying proportion of two different anions and an organic ligand. Partial substitution via doping during the initial synthesis with a macro-structurally similar (generating an isostructural material) yet chemically different anion creates a material with altered thermochromic properties. For example, in bromide-doped bis(N,N?-diethylethylenediamine)nickel(II)) tetrafluoroborate; both the tetrafluoroborate (BF4-) and bromide (Br—) derivatives are isostructural. Substitution of BF4- for Br— causes a decrease in the materials' thermochromic transition temperature by approximately 10° C.Type: GrantFiled: October 7, 2022Date of Patent: May 28, 2024Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventor: James August Ridenour

Publication number: 20240153763Abstract: Systems and methods for growth of silicon carbide over a layer comprising graphene and/or hexagonal boron nitride, and related articles, are generally described. In some embodiments, a SiC film is fabricated over a layer comprising graphene and/or hexagonal boron nitride, which in turn is disposed over a substrate. The layer and/or the substrate may be lattice-matched with the SiC film to reduce defect density in the SiC film. The fabricated SiC film may then be removed from the substrate via, for example, a stressor attached to the SiC film. In certain cases, the layer serves as a reusable platform for growing SiC films and also serves a release layer that allows fast, precise, and repeatable release at the layer surface.Type: ApplicationFiled: October 13, 2023Publication date: May 9, 2024Applicants: Massachusetts Institute of Technology, The Government of the United States of America, as Represented by the Secretary of the Navy, ROHM Co.

Patent number: 11977569Abstract: Disclosed is a natural language processing pipeline that analyzes and processes a corpus of textual data to automatically create a knowledge graph containing the corpus entities such as subjects and object and their relationships such as predicates or verbs. The pipeline is configured as an end-to-end neural Open Schema Construction pipeline having a coreference resolution module, an open information extraction (OIE) module, and an entity canonicalization module. The processed textual data is input to a graph database to create the knowledge graph displayable through a graphical user interface. In operation, the pipeline modules serve to create a single term for all entity mentions in the corpus that reference the same entity through coreference resolution, extract all subject-predicate-object triplets from the coreference resolved corpus through OIE, and then canonicalize the corpus by clustering each entity mention to a canonical form for mapping to the knowledge graph and display.Type: GrantFiled: January 28, 2022Date of Patent: May 7, 2024Assignee: The United States of America, Represented by the Secretary of the NavyInventors: Michael Lynn Potter, Natalie Lynn Larson, Amy Cheng, Hovanes Keseyan, Hanh Servin
