Abstract: The present invention relates to a class of polymer ion imbibed membranes for electrolyte flow batteries. The membranes are a conducting aromatic polyether type copolymer bearing nitrogen heterocycles groups, especially pyridine type. While the membranes can be used in acid, basic, and neutral electrolytes, the nitrogen heterocycles in the membrane interact with acid in the electrolyte to form a proton transport network, so as to keep the proton transport performance of the membrane. The membrane has excellent mechanical stability and thermostability as well as tunable porosity.

Abstract: Some embodiments provide a program. The program receives a state change that occurred for an event created by an application. The event includes a creator of the event, a set of objects, and a set of sources. The program further identifies a schema definition in a plurality of schema definitions based on a type of the state change that occurred for the event. Each scheme definition in the plurality of schema definitions specifies a type of state change and a set of information associated with the event. The program also generates a message comprising the set of information associated with the event specified in the identified schema definition and a set of targets. The program further sends the message to a message management platform in order for the message management platform to send to an application for presentation to each target in the set of targets through a web portal provided by the application.

Abstract: Some embodiments provide a program that receives from a client device a request for data feed items relevant to a user, determines a set of categories associated with the user, and queries a database for a first set of data feed items specify the user as a recipient of the data feed item. The program retrieves a second set of data feed items from an external content provider. The program modifies relevance scores of the first set of data feed items and the second set of data feed items based on the set of categories associated with the user and a set of factors, generates a result set of data feed items comprising the first and second sets of data feed items ordered based on the modified relevancy scores from highest relevancy score to lowest relevancy score, and provides the result set of data feed items to the client device.
