Results and discussion The most important information about the structure of the carbonized carbon material can provide scanning electron microscopy.
On this one of the objectives of the study was to develop a method of obtaining highly active bio-stimulator based on the application we have developed a carbon adsorbent with a nanoporous structure.
To do this, drew attention to the work performed in the laboratory of the structure and regulation of the enzymes of the Institute of Molecular Biology and Biochemistry, named after M.A Aitkhozhina.
This experiment was conducted with the assistance of a professor Z.A.Mansurov at the Institute of Biomedical Chemistry V.N.Orehovicha Russian Academy of Medical Sciences.The results of mass spectrometry are presented in Fig. 5.
These results indicate the suitability of the nanoporous structure of the carbon sorbent for the molecular-sieve chromatography of large protein-lipid complexes, such as sferosomy.

Nitrile-butadiene rubber (NBR)/OMMT nanocomposites could be obtained using melt-compounding followed by hot-press vulcanization. d-Spacings of OMMT were changed as the chemical structures of modifiers were varied.
X-ray diffraction (XRD) and tensile measurements of NBR nanocomposites revealed that the structures of organic modifiers affect the properties of NBR nanocomposites after vulcanization.
The effects of the chemical structures of organic modifiers on interaction between NBR and OMMT, and the properties of NBR/OMMT were evaluated.
The chemical structures of organic modifiers were confirmed 1H and 13 C NMR spectroscopy.
Tensile strengths of NBR/OMMT nanocomposites were dramatically changed by the structures of organic modifies.

In the present work Conventional and High Resolution Transmission Electron Microscopy has been used to examine the structure and types of interfaces between 3C-SiC and 6HSiC for samples grown by Sublimation Epitaxy.
The growth of bulk ingots and epilayers of quality allowing implementation of devices is not accomplished for the 3C-SiC which crystallizes in the cubic zinc blende structure and has to be grown on 6H-SiC due to the lack of 3C-SiC substrates.

It was found that the interfacial adhesion was enhanced, the size of the dispersed phase was reduced and PES and PC formed an interlocking structure with the copolymer, which suggest the addition of the compatibizer may improved the miscibility between PES and PC, and result in the improvement of the mechanical properties of the blends.
Materials: PES was obtained from the chemistry department of Jilin University.

This paper summaries the research status in application of the orderly function structure and looks into its future development.
Along with the rapid development of detection technology and manufacturing technology, a variety of functional effects of the micro-structured surface have been found, thus constructing or changing the surface micro structure so as to improve the surface properties of materials became a hotspot of current research.
Lotus leaf can be" self-cleaning" because its surface has a large number of micro-nano structure as well as the wax[8].
However, the existing preparation methods can not for industrial production because of low processing efficiency, involving complex chemistry, the demanding experimental conditions, higher cost etc., which make its practical application restricted.
People's diverse needs presents additional challenges for function structure.

It was shown that the structure of these compounds can be represented by stacking of close-packed Te layers.
These results can testify to the more stable structure and thermal properties of GST225 material with annealing.
As determined from XRD measurements, the annealed GST materials have stable hexagonal structures.
The similar behavior has been obtained for GST124 and GST147 structures also, but the changes are less considerable.
The carried out analysis of all stable and metastable GST crystalline structures and fitting of XRD data has shown that the diffraction pattern in Fig.7b cannot correspond only to single-phase structure of GST.
