Embodiments of the present invention provide an approach for a publisher-assisted, broker-based cache that can be utilized to reduce a volume of data (e.g., network traffic) delivered between a publisher and broker in a publication/subscription (pub/sub) environment. Specifically, in a typical embodiment, when a message is being generated on a publisher system, the publisher system will determine if the message includes a set of data that has a potential to be repeated in subsequent messages. Once such a set of data has been identified, the set of data will be associated/marked/tagged (e.g., in the message) with a unique identifier/cache key corresponding thereto (i.e., to yield a modified message). The modified message will be sent to a broker system, which will detect/locate the unique identifier, cache the corresponding data, and send the message along to any applicable subscriber systems. When a subsequent message that is supposed to contain the cached set of data is generated, the publisher system will instead substitute the unique identifier for the set of data to yield an abbreviated message and send the abbreviated message to the broker system. Upon receipt, the broker system will detect/locate the unique identifier, retrieve the corresponding set of data from the cache, replace the unique identifier with the set of data to yield a completed message, and then send the completed message to the applicable subscriber systems. |

The solid oxide fuel cell is also useful within a SOFC stack to generate electricity from unreformed hydrocarbon fuel. |

Composite electrodes for lithium ion battery and method of making
A method for making a composite electrode for a lithium ion battery comprises the steps of: preparing a slurry containing particles of inorganic electrode material(s) suspended in a solvent; preheating a porous metallic substrate; loading the metallic substrate with the slurry; baking the loaded substrate at a first temperature; curing the baked substrate at a second temperature sufficient to form a desired nanocrystalline material within the pores of the substrate; calendaring the cured composite to reduce internal porosity; and, annealing the calendared composite at a third temperature to produce a self-supporting multiphase electrode. Because of the calendaring step, the resulting electrode is self-supporting, has improved current collecting properties, and improved cycling lifetime. Anodes and cathodes made by the process, and batteries using them, are also disclosed. |
