    • Nano-catalysts that have utility for forming nanostructures and manufacturing nanomaterials are described. In some embodiments the nano-catalyst is formed from a powder-based substrate material and is some embodiments the nano-catalyst is formed from a solid-based substrate material. In some embodiments the substrate material may include metal, ceramic, or silicon or another metalloid. The nano-catalysts typically have metal nanoparticles disposed adjacent the surface of the substrate material. Methods of forming the nano-catalysts are disclosed. The methods typically include functionalizing the surface of the substrate material with a chelating agent, such as a chemical having dissociated carboxyl functional groups (-COO), that provides an enhanced affinity for metal ions. The functionalized substrate surface may then be exposed to a chemical solution that contains metal ions. The metal ions are then bound to the substrate material and may then be reduced, such as by a stream of gas that includes hydrogen, to form metal nanoparticles adjacent the surface of the substrate.

    • A method and a device for multithread to access multiple copies are provided. The method comprises: when multiple threads of a process are distributed to different nodes, a thread page directory table whose content is the same as that of a process page directory table of processes is created, and each thread page directory table comprises special entries for pointing to specific data and common entries except the special entries, in which each thread corresponds to a thread page directory table, the execution of each thread is based on the corresponding thread page directory table, and the specific data is the data with multiple copies at different nodes; for each thread, when each thread is dispatched and the special entries in the thread page directory table of the thread does not point to the specific data stored in the node where the thread exists, the special entries are modified to point to the specific data based on the physical addresses of the specific data. Based on the solution mentioned above, the threads distributed to different nodes can be enabled to access the data copy stored in the node where the thread exists, thus the system performance is improved.

    • The present invention discloses a master-standby switching method, system control unit and communication system. The method includes: a first system control unit transmits detection messages to an opposite network element according to a set detection period; when receiving a master-standby switching command, the first system control unit stops transmitting the detection messages, which makes a transmission link switching triggered because the first system control unit does not transmit the detection messages during a set timeout period; and at the same time, the first system control unit initiates a switching timer; and when detecting that the value of the switching timer reaches the switching timing value, the first system control unit performs a reset operation to implement the master-standby switching, wherein the switching timing value is greater than the timeout period. Before performing the reset operation for the master-standby switching, the system control unit in the present invention firstly stops, on its own initiative, transmitting the detection messages, delays stopping working for a period of time, until the transmission link switching is finished. Thus under the circumstance of the master-standby switching being performed, the packet loss of the service data messages can be reduced and the continuity and reliability of the service can be ensured.
    • 本发明公开了一种主备切换方法,系统控制单元和通信系统。 该方法包括:第一系统控制单元根据设定的检测周期将检测消息发送给相对的网元; 当接收到主备切换命令时,第一系统控制单元停止发送检测消息,这使得由于第一系统控制单元在设置的超时期间不发送检测消息而触发传输链路切换; 并且同时第一系统控制单元启动切换定时器; 并且当检测到切换定时器的值达到切换定时值时,第一系统控制单元执行复位操作以实现主 - 备用切换,其中切换定时值大于超时周期。 在执行主备切换的复位操作之前,本发明的系统控制单元首先首先停止发送检测消息,延迟停止工作一段时间,直到传输链路切换完成。 因此,在进行主备切换的情况下,可以减少业务数据报文的丢包,保证业务的连续性和可靠性。
