Abstract: A method for preparing isophorone diisocyanate by (1) reacting isophorone with hydrogen cyanide in the presence of a catalyst to obtain isophorone nitrile; (2) reacting the isophorone nitrile obtained in step (1) with ammonia gas and hydrogen in the presence of a catalyst to obtain isophorone diamine; and (3) subjecting the isophorone diamine to a phosgenation reaction to obtain the isophorone diisocyanate, wherein the content of impurities containing a secondary amine group in the isophorone diamine that undergoes the phosgenation reaction in step (3) is ?0.5 wt. The method reduces the content of hydrolyzed chlorine in the isophorone diisocyanate product, improves the yellowing resistance of the product, and the harm due to presence of hydrolyzed chlorine in the product is reduced.

Abstract: Disclosed embodiments provide computer-implemented systems and methods for determining a gap to meet a goal for use with a user interface. A method for determining a gap logistics comprises receiving, from a user device, a input, a target, and a request to determine a gap to determine the target based on the input for a set of groups, capturing sales data, price data, and funding data associated with the set of groups from a system, and determining the gap by applying the received input, the received target, the captured sales data, the captured price data, and the received funding data to a predefined formula. The method further comprises providing the determined gap to the user device and transmitting, from the user device, a request to provide a fund to close the determined gap to a computing device of an entity associated with the set of groups.

Abstract: Provided is a method for recycling and refreshing a cathode material, a refreshed cathode material and a lithium ion battery. The method for recycling and refreshing the cathode material includes: 1) a cathode material recycled from a waste battery is mixed with a manganiferous salt solution; 2) an alkali aqueous solution is added to the mixture to react to obtain a manganese hydroxide coating cathode material; and 3) the manganese hydroxide coating cathode material is sintered with a lithium resource to obtain a refreshed cathode material. The refreshed cathode material has no obvious impurity phase and has good crystallinity, high initial charge-discharge efficiency and good cycling performance.

Abstract: A method of preparing cathode particles using a co-precipitation reaction in a reactor is disclosed. A feed stream (a) containing metal cations is fed into the reactor, and a feed stream (b) containing anions is fed into the reactor, wherein a ratio of the metal cations in the feed stream (a) is continuously changed from A1 at time t1 to A2 at time t2. The feed stream (a) and the feed stream (b) are contacted in the reactor to form precipitated precursor particles, and at least one transition metal component in the particle has a non-linear continuous concentration gradient profile over at least a portion along a thickness direction of the particle.

Abstract: Notifications are delivered to a user based in part on a user's current context. The notifications may be based on personal information (e.g. calendar events, tasks, alerts, and the like) as well as a context of a user. The notifications may be delivered using different types of notifications. The type of notification selected may be based on the current context of the user. Notifications may also be sent to other users (e.g. that are part of a trusted group) in response to a change in state of the event (e.g. the task completed). Instead of a user receiving notifications at preset times, notifications are delivered to the user using their current context. A group member may also create a message to another member requesting an action. When a response is made, the requesting group member receives a notification and the other group members may also receive notifications.

Abstract: Example systems, methods, and data structures are directed at synchronizing documents. One example data structure includes receiving a request from a first client to edit a document, and sending short-term check out metadata to the first client to begin an editing session. The data structure includes a plurality of cells and a plurality of data objects defining content of the document. Each data object is associated with one of the cells and has an object identifier that uniquely identifies the data object within the associated cell, and is configured to communicate with other cells and with objects within the associated cell. In addition, each of the cells is defined so that each other cell remains unaffected by changes to data objects of the cell.

Abstract: Embodiments are provided for synchronizing file partitions utilizing a server storage model in a client-server computer network. Edits to content of an electronic document may be received at a client computer. The content may be included in a first partition of a file stored on a server computer. The first partition may include a first stream which includes the electronic document content. The file may include multiple partitions with each partition including one or more streams. The client computer may generate metadata in a second partition of the file. The metadata may be associated with the edits to the electronic document content in the first partition. The second partition may then be individually synchronized with the server computer to store the metadata. The first partition may then be individually synchronized with the server computer to store the edits made to the electronic document content.
