    摘要: A composite material having utility as an anode for lithium ion batteries comprises silicon, a transition metal, a ceramic and an electrically conductive diluent such as carbon. In particular instances, the ceramic is electrically conductive, and may comprise vanadium carbide or tungsten carbide. The transition metal may, in some instances, comprise iron. The material may be fabricated by grinding together a starting mixture of the components, and grinding may be accomplished in a high impact ball milling process, and the grinding step may cause partial alloying of the silicon with the metal and/or carbon. Further disclosed is a method for making the material as well as electrodes which incorporate the material.

    摘要: Communications between server computer systems of a cluster routinely exchange notice of configuration status and, on demand, transmit updated configuration data sets. Each status message identifies any change in the local configuration of a servers and, further, includes encrypted validation data. Each of the servers stores respective configuration data including respective sets of data identifying the servers known to the respective servers as participating in the cluster. Each status message, as received, is validating against the respective configuration data stored by the receiving server. A status message is determined valid only when originating from a server as known by the receiving server, as determined from the configuration data held by the receiving server. Where a validated originating server identifies updated configuration data, the receiving server requests a copy of the updated configuration data set, which must also be validated, to equivalently modify the locally held configuration data. The configuration of the cluster thus converges on the updated configuration.
