Desulfurization of Fuel Oils by Extraction with Ionic Liquids Xiaojiao YU1,a, Hailing HAO2,b,Jian ZHANG1,c,Gang ZHENG1,d,Binghua YAO1,e 1Faculty of Sciences,Xi’an University of Technology,Xi’an710048,China. 2 Institute of Chemistry and Chemical Engineering , Henan Institute of Science and Technology , Xinxiang, Henan453003,China.
A key feature of ionic liquids is that their properties can be tailored by judicious selection of cation, anion and substituents so they can be designed to perform selective liquid–liquid separations.
But the use of these PF6− and BF4− ionic liquids as large scale extracting agents is not optimal because of the relative high price of starting material and has strict temperature limitation in presence of water.

The Experimental Study on the fire suppression effectiveness of water mist with the FeCl2 Additives Jian Chen1, a, Ying Xuyan1,b , Na Wang1,c 1 School of Safety Engineering , Shenyang Aerospace University , China achenjian771123@126.com, bxyyhwzj@126.com, cwangna@126.com Keywords: water mist; FeCl2 additives; pool fire Abstract.This paper presents an experimental study of fire suppression effectiveness with water mist containing FeCl2 additives.The investigation focuses on suppression effectiveness under various FeCl2 additives concentrations,working pressures and nozzle different height above the fire source .
Iron-based compound as a new raw material has been paid extensive attention.
Key free radicals of combustion chain reaction such as H, OH, O, and so on, are absorbed when they collide with the FeCl2 particle, and can not continue to cause the branch chain reaction, causing a chain reaction interrupt.

A Wireless Mesh Network Node Query Method Research Zhigang Wang School of Information Engineering, Huanghe Science and Technology College, Zhengzhou, Henan, China 450063 Keywords: CFDA, Mesh, Time Sequence, Master-Slave Mode  Abstract.
The query key constraints are as follows: It has been passed to query the positioning of the sub-node, not in response to the column, such as a collection of S: {S1, S2, S3, and Sn}.
New node without regard to the previous node, save a lot of human and material resources, and the network is quite stable.

Introduction SiC/SiC composites are important ceramic materials because of their resistance at high-temperature in oxygen-containing atmosphere [1].
One route to produce SiC/SiC composites is a complete infiltration of porous SiC/C materials with liquid silicon (LSI) [2].
Phenolic resins are suitable for producing porous carbon materials with high carbon yield compared to other carbon precursors [7,8].
