Publication number: 20250002354Abstract: Embodiments described herein relate generally to the large scale production of functionalized graphene. In some embodiments, a method for producing functionalized graphene includes combining a crystalline graphite with a first electrolyte solution that includes at least one of a metal hydroxide salt, an oxidizer, and a surfactant. The crystalline graphite is then milled in the presence of the first electrolyte solution for a first time period to produce a thinned intermediate material. The thinned intermediate material is combined with a second electrolyte solution that includes a strong oxidizer and at least one of a metal hydroxide salt, a weak oxidizer, and a surfactant. The thinned intermediate material is then milled in the presence of the second electrolyte solution for a second time period to produce functionalized graphene.Type: ApplicationFiled: May 8, 2024Publication date: January 2, 2025Applicant: NanoXplore Inc.Inventors: Marie BOZALINA, Philippe Perret, Soroush Nazarpour

Publication number: 20240419651Abstract: A device, system and method for data lineage tracking, reporting and database updating is provided. A first device alters metadata of data to include an identifier. A second device receives the data and implements a data pipeline to process the data to generate altered data that includes the identifier in respective metadata. A metadata identifier engine of the second device processes the altered data to identify the identifier in the respective metadata, and provides a usage indication (including the identifier) of the data to the first device. The first device stores the indication as a data lineage data, processes the data lineage data to determine usage of the data by the second device, and provides information indicative of the usage of the data by the second device over a computer network such that users of the computer network have immediate access to up-to-date data lineage data associated with the data.Type: ApplicationFiled: February 16, 2024Publication date: December 19, 2024Inventors: Michel DEMAZEAU, Jean Philippe PERRET, Emeline RADIGOIS, Loic DRIENCOURT

Patent number: 11898858Abstract: Systems and methods for determining a set of routes using a graph having nodes and links connecting the nodes. The routes are determined for one or more tokens, and each token is associated with an origin node and a destination node included in the graph and with a token weight. Token constraints, which include at least one constraint relative to the token weight, are received for each token. Candidate routes satisfying at least some of the token constraints are received for each token. Each candidate route includes at least one route link included in the graph and the each route link is associated with a link weight. Shared route links are those route links that share at least two tokens. The candidate routes are filtered based on a condition related to the link weight of each shared route link and to the weights of the tokens sharing the link.Type: GrantFiled: September 1, 2020Date of Patent: February 13, 2024Assignee: Amadeus S.A.S.Inventors: Michel Demazeau, Jacques Bonaud, Marco Salibba, Jean-Philippe Perret, Celine Soubra

Patent number: 11157501Abstract: Methods, caches, database systems and computer program products for processing database requests and retrieving results from the cache of a database system. The cache stores a representation of a data space of one or more databases of the database system, including one or more results for any database request for which the data space is able to output a result. In response to receiving a database request from a client, the cache determines by utilizing the stored representation whether the data space is able to output one or more results for the database request. If affirmative, one or more results are returned to the client from the representation of the cache. Otherwise, the cache returns an invalidity notification.Type: GrantFiled: May 10, 2019Date of Patent: October 26, 2021Assignee: AMADEUS S.A.S.Inventors: Michel Demazeau, Celine Soubra, Jean-Philippe Perret, Marco Salibba, Jacques Bonaud
