Pure silica mesoporous materials possess a neutral framework, which limits their application in catalysis.
To obtain materials with potential for catalytic application, it is necessary to modify the nature of the amorphous walls by incorporation of heteroelements.
The red shift idicates that heteroatoms are incorporated into the framework of mesoporous materials and Si-O-M bonds were formed[6].

These suggested that there are a lot of deficiencies on the CNTs and are difficult to disperse in matrix materials.
The line structure means that WMWCNTs are easily dispersed in matrix materials than traditional CNTs which are twined together.
The cooked CNTs also have low crystallinity and are difficult to be dispersed in matrix materials such as cathode and anodes of lithium ion battery and polymer composite material.
The WMWCNTs can be dispersed easily in matrix materials.
WMWCNTs can be used widely as addition for application in lithium ion battery and nanocomposite materials.

Preliminary Research on One Multiband Smoke Material Preparation Weidong Xu1, a, Heng Liu2, a, Shashi Zhang3, a, Jianghua Wu4, a, Jinsong Zhu5,b 1,2,3,4 Institute of Field Engineering, University of Science and Technology, PLA 5 Institute of Sciences, University of Science and Technology, PLA No. 1 Haifuxiang Rd., Qinhuai District, Nanjing, Jiangsu, China.
As a result of the latest development of TIR sensing technology and PGW, materials such as red phosphorus are added to enhance camouflage smoke to interfere with TIR.
Experiment Materials.
In the light of smoke electromagnetic attenuation theory and considering future practical demand of smoke materials, the multiband smoke agent can be applied to interfere with visible lights, TIR and MMW, being wide in shielding area, quick to generate smoke, long for hanging time, effective in material, strong in stability, low in cost and harmless to human body.
Orthogonal experimental method is employed to save material and time, considering different kinds and different formulations of the four materials will inevitably influence the smoke effect after combustion.
