Scanning electron microscope (SEM) was used to examine the membrane structure.
From the SEM, preliminary cast membrane structure displayed a long finger-like near the outer and inner walls sandwiched a sponge-like structure that provided the membrane strength.
It can be seen from Fig. 2 that near the outer and inner walls of the membrane, long finger-like structures and that at the center of the flat sheet, sponge-like structure can be seen.

Hydrocyclones are widely used for particle separation due to advantages such as: low cost, simple structure, large capacity and small volume.
Introduction The use of hydrocyclones for particles separation is widespread due to advantages such as low cost, simple structure, large capacity and low volume.
Thus, three structures of mantle vortex finder were built for this study, whose cross sections are illustrated in Figure 3.

Vesiculosus after polysaccharides, the development of new approaches to extract these components based on the principles of "green chemistry" is necessary.
Phlorotannins are an extremely heterogenous group of phenolic compounds in terms of structure and degree of polymerization.
Examples of the structures of phlorotannins: 1 – phloroglucinol; 2 – eckol; 3 – fucodiphloroethol.
Vesiculosus were carried out in a microwave reactor constructed at Lignin Chemistry Laboratory under the following conditions, with or without vacuumation, see Fig. 2.
Acknowledgment This research was funded by a Bio-economic grant “BioPro4Eco” from the Latvian State Institute of Wood Chemistry.

Coordination, solvation, aggregation and redistribution equilibria play an important role in the chemistry of the modified titanium alkoxides [4].
Conclusion: Thus, in view of the aforesaid result and discussion it is proposed a cis-octahedral structure of diolato complexes of titanium (IV) geometry in which titanium (IV) is hexacoordinated (Fig.1).

Supramolecular functionalization of SWCNTs with porphyrin and their derivates is mainly attributed to these flat, aromatic structures that are ideal for π-stacking interactions with SWCNTs[7].
Furthermore, there have additional 1332cm-1 and 1220cm-1 characteristic peaks carried in chitosan/H2CPTPP, which further demonstrated that the H2CPTPP molecules containing phenyl ring structure were successfully introduced to the chitosan.

Also, showing that the surface PANI/TiO2 successful assembly of the SiW11Ti, and its Keggin structure remained intact.
This shows that polyaniline-modified TiO2 particles prepared by ‘in situ’ polymerization do not change the crystalline structure of neat TiO2.
Along with polymerization, part of the small particles form a layered structure and another part of the form of small particles deposits on the surface of layered structure.

The structure of N4222TFSI was characterized by FT-IR, 1H-NMR and 13C-NMR.
However, their structures (R2R′2N+X--type) were fixed by the reaction mechanism.
From the characterization of the products prepared by using microwave and oil bath, it was found that their structures were the same.
The reason might be that there was no conjugate structure in the raw material.
