It is believed that the dispersion agent could coat the silica surfaces as they are being broken down during the mixing and then stabilize the dispersed structure by stearically preventing silica reagglomeration.
The additive could coat the silica surfaces as they are being broken down during the mixing and then stabilize the dispersed structure by stearically preventing silica reagglomeration5.
Figure 3 Figure 4 Figure 3 and Figure 4: Influence of mixing stage and additives on viscosity and dispersion in Epoxidised Natural Rubber compound Results showed that a three stage- mix can give an excellent dispersion owing to the high viscosity of two stage and this procedure can be recommended for dispersion of hard to disperse of filler low structure.

Study on Grain Boundary Sensitization in Heat Affected Zone of Austenitic Stainless Steel and Its Evaluation Method Bo Zhao1,a, Qiang Dai1,b, Zhijuan Zhao1, c, Meng He1, d, Lixian Wang1,e,*, Guanghui Zhang2.f 1Institute of Chemistry, China Special Equipment Inspection and Research Institute, Beijing, P.R.
In this paper, the simulated welding structure at different areas of heat affected zone (HAZ) of austenitic stainless steel are prepared by heating furnace, and the deference of intergranular corrosion resistance of all samples were determined by comparative methods of oxalic acid etching, hot-acid test and electrochemical potentiodynamic reactivation tests (EPR), and the effectiveness of all those methods were analysis and determination at the same time. 
The result shows that the susceptibility degree at different areas of HAZ increased with the heating temperature increase, but all structures can pass hot-acid test and EPR test, indicating that it could maintain good performance of intergranular corrosion resistance.
Type of Structure Classified Types Microstructure in Microscope Heating Temperature 700℃ Dual Structure Some ditches occurring at grain boundaries but no grain being completely surrounded by a ditch. 800℃ Dual Structure Some ditches occurring at grain boundaries but no grain being completely surrounded by a ditch. 900℃ Step Structure No ditches found at grain boundaries. 1000℃ Step Structure No ditches found at grain boundaries. 1100℃ End-Grain Pitting I Structure contains a few deep end-grain pits along with some shallow etch pits 1200℃ End-Grain Pitting I Structure contains a few deep end-grain pits along with some shallow etch pits 1300℃ End-Grain Pitting I Structure contains a few deep end-grain pits along with some shallow etch pits Original Step Structure No ditches found at grain boundaries.
As shown in Table 2, the simulated microstructure of HAZ of austenitic stainless steel heated to 700-800 °C is classified as “Dual Structure”, indicating that the intergranular corrosion stabilization of austenitic stainless steel should be increased. when the heat treatment temperature rises above 1100 °C, it is obviously transformed to the “End-Grain Pitting I” of microstructure, indicating that there are obvious pits and the grain microstructures will be eroded.

A porous membrane of LiCoO2 with three dimensionally ordered macroporous (3DOM) structure was obtained.
The prepared material had a rock-salt type crystallographic structure with mR3 space group.
LiCoO2 has a rock-salt type structure (space group: mR3 ), and Li+ ion can be inserted into the crystallographic structure reversibly at the electrode potential of 3.9 V vs.
Through this procedure, porous ceramic membrane with an inverse-opal structure was obtained.
Indeed, the 3D macroporous structure was collapsed at higher than 800 °C due to the grain growth.

However, the application of new processes requires taking into account effects that were not considered in riveted structures.
An integral structure can be obtained using welding processes, creating material continuity between the different parts, [6].
Another difference between welded and riveted structures is the residual stress field since the application of heat and sequential cooling creates internal stresses that may be beneficial or detrimental for the structure.
