Ca3Co4O9 has a layered structure and belongs to monoclinic system.
Electric CoO2 layers in the Ca3Co4O9 material have octahedral structure which central atom is Co.
Therefore, the energy band structure of the material changed, and so the Seebeck coefficient is improved.
The factors such as temperature, crystal structure, porosity and so on, may affect the thermal conductivity.

F J Gordillo-V´azquez [9] have used a general quasianalytic space–time averaged (zero-dimensional) kinetic model to study the non-equilibrium plasma chemistry of C2H2 (1%)/H2/Ar at different pressures, and did not consider the plasma in space on the distribution.
Its plasma chemistry is complex and does not consider the effects of particle deposition.

Schema.9 Methyl rhenium trioxide catalyzed oxidation Schema.10 Structure of new catalyst reaction of cyclic ketones in ionic liquid Linden A A et al [13] studied a new catalyst in the ionic liquid [bmim][PF6] (schema.10).In the catalytic oxidation of hydrogen sulfide, the yield of oxidation product sulfoxide was high, selectivity was also very good.
Schema.15 Catalytic oxidation mechanism of desulfation by [hmim]3PMo12O40 Conclusion and prospect Ionic liquids have aroused extensive attention as a green chemistry with the current development and the increased environmental awareness in recent years.
Thus, it’s the inevitable improvement trend of green chemistry and chemical engineering that the catalyst which is not economic and cannot meet the requirements of green chemistry must be replaced by the functional ionic liquids.

Then some natural antioxidants including ascorbic acid, tea polyphenol, tea polysaccharide, proanthocyanidins, flavonoids, resveratrol, water-soluble dietary fiber and antioxidant peptide are becoming the research hotspot in different areas of food science, food chemistry, biochemical nutrition, epidemiology and preventive medicine [3].
Because a certain protease maybe only act on some peptide bonds or peptide bonds formed by special group amino acid, various proteases have different effects on the same sort of protein substrate, at the same time, the primary structure and length of the peptide chain in hydrolysates are also quite different.
