For the last neutral system, the effect of different synthesis condition on the spheres’ morphology and structure was studied mainly from the temperature[5,6], surface concentration[3,7,8]and solvent composition[9,10,11].
Every image exhibited the worm-like porous structure, which is the typical characteristics of synthesized SiO2 spheres using neutral template, however, there was not any obvious changes in pore size with the variation of MH/ME.
According to the BDDT [14], both samples displayed typical Langmuir Ⅰ pattern indicating the presence of microporous structure.

Development and Characterization of Novel Conductive Nanofiller Based on Multi-Walled Carbon Nanotubes Grafted with Poly(3,4-Ethylenedioxythiophene) Guna Vugule1,a, Ingars Reinholds2,b*, Janis Zicans1,c, Remo Merijs Meri1,d and Kaspars Ozols3,e 1Institute of Polymer Materials, Faculty of Materials Science and Applied Chemistry, Riga Technical University, Latvia 2Faculty of Chemistry, University of Latvia, Latvia 3Institute of Technical Physics, Riga Technical University, Latvia aguna.vugule@gmail.com, bingars.reinholds@lu.lv, czicans@ktf.rtu.lv, dRemo.Merijs-Meri@rtu.lv, eKaspars.Ozols@rtu.lv Keywords: MWCNTs, functionalization, poly(3,4-ethylenedioxythiophene), electrical conductivity Abstract.
The changes in structure, thermal stability and electrical conductivity of the developed nanofiller are analyzed in comparison to that of pristine MWCNTs applied in this research.
Renishaw InVia Raman spectrometer with 514 nm excitation was used for the structure characterization.
The results also showed less effect of functionalization on the change in the graphitic crystalline structure of MWCNTs.
The study of Raman spectroscopy indicated change of the structure of MWCNTs.

It was reported that the concentration of the acid hydrolysis medium play an important role in controlling the crystal structure and morphology of the synthesized TiO2 [4].
Cano-Casanova et al [6] prepared TiO2 photocatalysts by a one-step hydrothermal process at 350 ºC and short time using aqueous HCl solutions as hydrolysis media, the investigated variable is the concentration of the HCl solution, which pay attention to the degree of crystallinity and the surface chemistry.
It was also reported that the pH of titania solution could affect not only on the crystallization and phase transformation, but also on the formation of mesoporous structure of TiO2 [7].
The crystal structure of the two crystal forms and the third rule of Pauli were Combined: in the same coordination structure, the coordination polyhedron does not tend to share the edges, especially the non-sharing surface.
Polymorphic phase transition among the titania crystal structures using a solution-based approach: from precursor chemistry to nucleation process, J.

But either way, each method still has some deficiencies, such as structure damaged, complex steps and low yield.
Similarly, chemical oxidation method will damage the structure and properties of CNTs seriously [12].
It is widely recognized that as oxidative activity of amorphous carbon is greater than CNTs which have graphite structures.
However,they may disrupt the carbon nanotubes perfect structure and some physical properties.

Porosity was used to verify membrane structure.
The micro-structure of membrane emerges some defects and results in flux increasing.
The effects of hydrophilic of blend membranes would become weak with the high SPSF content, while the structure of the membrane is more important to the water flux.
When the ratio of PES/SPSF exceeds 4/1, as shown in fig.7 (C), the structure of the membrane is denser than others without macrovoid.

The main problem of the LiFePO4 is low electronic conductive and low lithium ion diffusivity owing to the limitation of its crystalline structure [2].
We also studied the structure, morphology and electrochemical performances of the composites.
This suggests that the trifle F dopant did not affect the structure of LiFePO4 material.
The trifle fluorine dopant did not affect the structure of the material but considerably improves its electrochemical performances.

The structures of the products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM), and their optical properties were studied by UV-Vis spectroscopy.

A valve is called the “throat” in various kinds of pipe network systems of enterprises in petroleum, electricity and chemistry industries.
These devices have been widely accepted as effective safety management tools and are being accepted and used by master petroleum, natural gas and chemistry manufacturers in the world [2].
