Abstract: An electrode composed of a substrate including a graphene layer coated on a first metal; and a complex including a second metal deposited on the substrate and a hydroxide of the first metal, where the complex is in the form of core-shell in which the second metal is a core and the hydroxide of the first metal is a shell, and the second metal has a higher standard reduction potential than the first metal. The graphene-coated metal foam of the present invention is the first case that proves not only theoretically but also by experiment that the remarkable catalytic ability reducing other metals (Au, Pt, Ag, and Cu, etc.) with a higher reduction potential than the metal by graphene coated on the metal surface it electroless deposition without additional reductant or electrical reduction conditions is due to the electrical double layer or interfacial dipole induced between the graphene and the metal.

Abstract: An external bed type double-fluidized bed system for preventing boiler contamination includes a fluidized bed combustion furnace, a cyclone separator, a coal ash distributor and a fluidized bed pyrolysis furnace. The fluidized bed combustion furnace is connected with the coal ash distributor, the coal ash distributor is connected with the coal ash inlet on a side wall of the fluidized bed combustion furnace through a return feeder with which the coal ash outlet of the fluidized bed pyrolysis furnace is also connected through an external bed, and the return feeder is connected with the fluidized bed combustion furnace. A fuel coal is pyrolyzed in the fluidized bed pyrolysis furnace at a temperature to volatize alkali chlorides into a pyrolysis gas, thereby reducing the content of the alkali chlorides contained in the coal in the fluidized bed combustion furnace and relieving the contamination to a convective heat-absorbing surface.

Abstract: SOAP client protocol encapsulation Based on TCP , based on the short TCP connection, SOAP client protocol encapsulation method, the client package for SOAP protocol, that is Web Services Description Language WSDL file into xml file, put to the client application's configuration file which, variable part of the SOAP protocol allows all the code from the configuration file object after conversion, and then generated after the body of SOAP protocol: 1) client load WSDL converted xml file; 2) the client application to read out the configuration file, the xml with the application to transfer data into a SOAP message body; 3) in the generated SOAP message body together with SOAP message header, turned into a complete SOAP request; 4) We will be based on TCP short connection to the complete SOAP request sent to the web services server, then receive and process about the content of web services to return, to complete a full SOAP interface calls; All the web Services client: a client using the same source, and adopt a

Abstract: As for the data transfer method based on MAP, adopts a MAP data structure during the data transferring process and configures it using SOID (Standard of Interface Department) syntax after encapsulation; the definition of MAP data structure; one system consists of many matching and individual source ends and target ends, one source end just accesses to its matching target end, and vice versa, all member methods of source and target end adopt MAP structure to transfer data, logic implementation steps are shown as below: data processing of database is the most basic and most featured part of BRS system which adopts SOID syntax, if a table is not simply imported into another Oracle database, it should be treated by another process, that is, generate a derived class directly, and then rewrite “Key process”; data transfer method based on MAP bring excellent compatibility. It nearly supports all kinds of existing platforms, protocols, businesses and manufacturers.
