Abstract: The invention relates to a particulate material and processes for the preparation thereof. The particulate material consists of a plurality of composite particles. The composite particles comprise a porous particle framework comprising micropores and/or mesopores. The total pore volume of micropores and mesopores as measured by gas adsorption is in the range from 0.4 to 2.2 cm3/g. The composite particles comprise a plurality of electroactive material domains and a plurality of modifier material domains disposed within the internal pore volume of the porous particle framework. At least a portion of the modifier material domains are located between adjacent electroactive material domains.

Abstract: This invention relates a process for preparing composite particles. The process comprises a first step of providing a plurality of porous particles comprising micropores and/or mesopores, wherein the total pore volume of micropores and mesopores as measured by nitrogen gas adsorption is in the range from 0.4 to 2.2 cm3/g. The porous particles are contacted with a precursor of an electroactive material at a temperature effective to cause deposition of the electroactive material in the pores of the porous particles to form intermediate particles. Deposition of the electroactive material is discontinued and by-products are optionally separated from the intermediate particles. The intermediate particles are then contacted with a precursor of an electroactive material, at a temperature effective to cause further deposition of the electroactive material in the pores of the intermediate particles to form the composite particles.

Abstract: A system and method are provided which include receiving, from a first application on a user device, an indication that a user has been authenticated and receiving, from a second application on the user device, an indication that the user is detected. The user device receives the indication that the user is detected from a wearable device on the user. Based on receiving the two indications within a time period, a trust token is generated or maintained for the user.

Abstract: Disclosed are methods and systems for enabling an assertion to be provided to a relying entity that is associated with a discount or digital coupon for an item in a transaction. The assertion may indicate an interaction by a user device with a digital indicator associated with the item and/or a resource provider offering the item. The assertion may be associated with a user and redeemed at a later time to apply a discount for an item involved in a transaction. The assertion may indicate an interaction with a digital indicator at one location for an item and redeemed at another location, including an online transaction, for the same item.

Abstract: A system and method are provided which include receiving, by a server computer from a trusted entity computer, user data corresponding to a user. Based on the user data, the server computer determines a set of assertions for the user. The server computer receives, from a relying entity, an assertion request for the user. Responsive to the assertion request, the server computer provides, to the relying entity, an assertion, of the set of assertions. The relying entity thereby grants the user a particular type of account based on the assertion.

Abstract: Methods and systems disclosed herein relate to providing a receiving entity with a package of assertions. A package of assertions may include a group of yes or no statements (e.g., as an answer to a question). Alternatively, or additionally, a package of assertions may comprise a clustered assertion, which is a singular yes or no statement, that is itself based on a set of underlying assertions made using information from one or more sources. A particular type of package of assertions may be selected based on the relying entity requesting the assertions, based on an assertions model. The package of assertions may be cryptographically secured.

Abstract: This invention relates to particulate electroactive materials consisting of a plurality of composite particles, wherein the composite particles comprise: (a) a porous carbon framework including micropores and mesopores having a total volume of 0.5 to 1.5 cm3/g; and (b) silicon located at least within the micropores of the porous carbon framework. The porous carbon framework is an activated carbon material obtained by the pyrolysis of a plant source comprising at least 25 wt% lignin on a dry weight basis followed by activation with steam or carbon dioxide.

Abstract: Disclosed are methods and systems for enabling a package of assertions to be provided to a relying entity seeking to interact with an account. A server computer may receive, from a relying entity, a request for assertions, wherein the request for assertions includes an identifier of the relying entity and a hash of an identifier of an account. The server computer may determine an assertions model based on the identifier of the relying entity. The server computer may retrieve a package of assertions associated with the account based on the assertions model and the hash of the identifier of the account. The server computer may transmit the package of assertions to the relying entity.
