However, studies on that structure-activity relationship of Antioxidant peptide and its anti-oxidation mechanism, protein hydrolyzate antioxidant enzyme activity and specificity, degree of hydrolysis and the amino acid composition and sequence of different peptides have not been fully established[12].
Further studies would have to be done in order to research the structure, the physiological activity and application of the antioxidant activity from Pinctada fucata muscle .

Doping activation and mineralization are the main investigating topics of cement clinker chemistry.
The mineral feature and structure were recorded on a Hitachi S-2 500 scanning electron microscopy (SEM), equipped with an Oxford Link ISIS-30 energy dispersive spectroscopy (EDS).
XRD and SEM-EDS analysis are conduct to further investigate the composition and structure of clinkers.

Main factors influencing the structure of small production industry providing a range of goods in each specific case are as follows: ¾ Technologies used at the enterprise; ¾ Frequent use of typical processes and of typical and standard equipment; ¾ Use of equipment that can operate within a wide range of operational parameters, such as capacity, temperature, pressure, etc.
One of such characteristics is the requirement set for the structure of the process flow diagram for wastes recycling that states that groups of compatible equipment are possible to be allocated in different compartments within a workshop.

After the milling process, B-S1 particles started to show structure degradation and agglomeration as shown in Fig.1 (d).
After milling, the particle structure of perovskite had been significantly destroyed by the collision and impact in milling.

Chemical Bond and Property of TiC-TiB2 Composite Xinmin Mina and Tao Wangb Chemistry Department, School of Sciences, Wuhan University of Technology, Wuhan 430070, China awhutmxm@126.com, bbluejack911@qq.com Keywords: TiC-TiB2; Composite; Chemical bond; Property.
The electronic structure makes the main effect on the property of the materials, but the structures of TiC-TiB2 composite and doped series are not studied so far and not clear.
TiC has a structure of NaCl type.
TiB2 has the space group of P6/mmm and the layer structure with B6 and Ti7 (one Ti atom is in the center) hexagons.
Comparing with the structure of TiB2, there is Ti7 hexagon structure of TiC cell in the direction of the diagonal of the cube model, which is similar to Ti7 in TiB2 and the length difference of hexagonal sides is less than 10% between TiB2 and TiC.

The structure of PAESK was confirmed by FT-IR, 1H-NMR and characterized by XRD. thermogravimetry (TG) and Differential Scanning Calorimeter (DSC) were carried out to demonstrate its good melt processability.
The cross-linked structure could apparently low the glass transitions temperature (Tg), in contrast to PPESK, which could improve melt processablility.
Due to the possible structures of CBCBSB, prepared PAESK mentioned above has different structures as A; B and C, depicted as scheme 3.
It is due to the synthesis from dichlone monomer with the irregular structure both including of sulfuryl and carbonyl.

As because silver is fcc structure and have high stacking fault energy the twin structure is observed at high temperature.
This is the reason for low sheet resistance for this type of structure.
Again compare to nitrogen atmosphere argon atmosphere facilitates to form faceted singular structure more.
Reference [8] shows square shape faceted structure.
This high temperature annealing produce pore in to structure.

Because of the difference in its composition and structure, the cell walls of plants can be degraded to different degree [1].
Lignocellulose is a macromolecule polymer, due to that the complexity of the structure is exquisite, benzene ring structure is quite stable, with plants in the package effect of cellulose and hemicellulose, lignin and cellulose crystalline structure on the biodegradation of inhibition, it is very difficult to make lignocellulose hydrolysis, which limit the use of it for a long time.
Although rumen system can effectively degrade economy, but due to the physical and chemical structure, cellulose degradation efficiency is still not high.
