Introduction The synthesis of schiff base has been a hotspot for its advantages in the field of chemistry and biomedicine research in recent years [1, 2].
The structures of three novel ASBs were determined by a Fourier transform infrared spectrophotometer (Spectrum 100, PerkinElmer Company, USA).
The molecular structures of three ASBs are shown in Fig. 1.
The CD spectra of BSA exhibited two negative bands in the UV region at 208 and 222 nm, characteristic of an α-helical structure of protein [26].
From the above equation, the quantitative analysis results of the α-helix in the secondary structure of BSA were obtained.

Weak peaks, corresponding to Y zeolite structure, appear after crystallized for 24 h in Fig.1 (b).
Fig. 3(a) presents irregular shapes without integrity crystal structure, which is amorphous aluminosilicate material.
Few regular shapes particles are observed in Fig. 3(b), suggesting that NaY zeolite crystal structure is hardly formed from amorphous aluminosilicate.
When the temperature increase from 220 to 1000 °C,the weight has little reduction, indicating that the structure of NaY zeolite has no variety.

This compound, as implied by its structure, consist of active clusters which include amines, hydroxyls, and hydrophilic.
Those groups are capable of holding water in its structure and also capable of forming gel spontaneously [3].
This trend is related to the molecular structure of each species involved in the complex.
In the structure of chitosan, there is one weakly basic amino group per pyranose ring.

After rolling, the structure of the powder is gradually transferred from bulk layered-cellular mass into packaged form.
The structure of the particles is flatter than the bulk after leaving the deformation zone.

A biopolyester family is widely investigated as coating because of its hydrophobicity from their molecular structures.
This indicated high water resistance efficiency of the shellac coating layer due to its water-insoluble structure [11].
This indicated that, in this case, either NFC or mNFC had no function in term of mechanical properties or in increasing the inter-fiber bonding inside the BG sheet structures because they were coated only on their surfaces [13].
It suggested that the penetration of shellac inside the sheet networks led to a greater bonding degree of the bilayer coated sheet structures, allowing them higher load-bearing capability as well as more resistance to deformation [14].

Despite from the indentation loads, porcelain hardness is also influenced by the crystalline structure formed in the porcelain.
Crystalline leucite is a crystalline phase that has a cubic shape, while other porcelain structures (silicates) are tetrahedral.
Decreasing abrasiveness will help reducing the wear of porcelain restored tooth structure [5].
Although it has not been able to match the tooth enamel’s hardness, it is closer to the tooth structure compared to Prado’s conventional porcelain hardness value (680 VHN) [3,15].

For potential parameters of single component systems, experimental material properties of the most stable structures are used for fitting.
Here, as a reference structure of such binary systems, the structures of FCC (A2B2)[2] are selected.
Selection of a reference structure involves arbitrariness.

Fibrous structures have a high surface to volume ratio and transport is possible only along fibers - this determines the kinetics of structure formation and transformations during synthesis.
Materials, having low density or high porosity, high specific surface area and fine grain structure, are needed for catalysts, sensors, filtration membranes, composites, etc.
The composition and the structure of hydrated alumina filaments produced by this way were described by Pinel and Bennett [2].
The PAM structure consists of amorphous nanofibrils of aluminum oxihydroxide with composition Al2O3·4H2O or [Al(OH)3]2·H2O.
Also, an average interatomic distance in SiO2 can interfere with the lattice constants of the forming phase structure.
