  • Patent number: 11958038
    Abstract: A group of reductive 2D materials (R2D) with extended reactive vacancies and a method for making the R2D with extended reactive vacancies are provided, especially the example of the reductive boron nitride (RBN). To create defects such as vacancies, boron nitride (BN) powders are milled at cryogenic temperatures. Vacancies are produced by milling, and the vacancies can be used to reduce various metal nanostructures on RBN. Due to the thermal stability of the RBN and the enhanced catalytic performance of metal nanostructures, RBN-metals can be used for different catalysts, including electrochemical catalysts and high temperature catalysts.

  • Patent number: 10691877
    Abstract: Organizations maintain and generate large amounts of documentation and entities of these organizations often need to collaborate on generating and reviewing this information. There is a need to maintain and store this documentation remotely in such a way that the entities of these organizations may collaborate with each other. To ensure that entities of the organization can collaborate on documents, an overlay creation and storage system is described. The overlay may be usable by a computing device operated by the entities of the organization. Furthermore, information contained in the overlay may be injected into the document.

  • Patent number: 10567382
    Abstract: A method and apparatus for controlling access to documents retained by a document management and collaboration system is disclosed. The document management and collaboration system may generate one or more suggested privileges associated with one or more users. An access control policy may specify whether system-generated user privileges may be enforced. If they are enforced, access to one or more document may be made subject to the generated privileges.

  • Patent number: 10430504
    Abstract: An example method includes receiving an input via a computing device indicative of a request to display a plurality of visual identifiers, each visual identifier corresponding to a different respective version of a document stored in at least one remote document management system. The method also includes receiving information from the document management system, determining a chronological sequence associated with displaying the plurality of visual identifiers; and generating a respective visual identifier representative of each version of the document. The method also includes displaying the visual identifiers on a display of the computing device according to the chronological sequence.
