Among these metal-oxides, TiO2 was mostly used as photoanode material with the highest efficiency of approximately 11% [4-6] due to low cost, suitable bandgap, sensitivity to the light, high structure stability under irradiation, excellent chemical and thermal stability [7-8], and large internal surface area, which maximize the uptake the dye molecules [9].
Then the photoanode was assembled into a DSSC sandwich structure with a Pt plate as the counter electrode, and the liquid electrolyte (Mosalyte TDE-250) was injected into the internal space of the cell.

The crosslinked structure hinders the mechanical processes typically used for recycling other materials.
These interactions are often generated by the application of chemistry in the rubber [7].
This limits future studies on the relationship between the structure and properties of self-healing NR and the development of reversible rubber crosslinks.
The research found a strong connection between the ability of ionic supramolecular network to form solid structures and the ability of a sample to recover 95% of its tensile strength after 5 minutes.
They suggested that ZDA, which contains the same Zn2+ ion as ZDMA but has a different chemical structure may fulfil the same function.

Due to the structure of proteins, which have one or more regular polypeptide chains, proteins make one of the materials useful for a wide variety of applications. [4].
This is because the CNF sample in the form of a gel was dried using the oven and then grounded until smooth, which damaged the structure of the CNF.
Because there was a change in the internal structure caused by the addition of CNF, the bioplastic matrix underwent a change which caused the crosslinking to become stronger.
However, there’s a limitation for the use of CNF in bioplastic with a 5% maximum because it can damage the bioplastic structure [10].

X-ray diffraction (XRD) measurements were operated on a D/Max-3B X-ray diffractometer to determine the crystal structure of the catalyst with the diffraction angle 2θ from 20 ~ 80°, step size 0.02°.
Meanwhile, the other five diffraction lines (at about 28.60°, 33.10°, 47.50°, 56.30°and 59.10°), correspond to (111), (200), (220), (311) and (222) crystalline phase of CeO2 which has a cubic fluorite structure [4].
Although the diffraction peaks of γ-Al2O3 decrease, it does not disappear, and there is no appearance of new diffraction peaks, implying that crystal structure of original catalysts is not changed and new species are not generated by adding CeO2.
KiliK [14] deemed that Pd particles would form the surface structure Pd-Cl-Ce by chloride ion when Pd, Ce and Cl coexist.

The first characterization was the cleavage of bond, which make the molecular weight being decreased or molecular structure to change.
The cleavage of bond and the change of the molecular structure molecular can counteract negative effects of polymerization.
The binding energy of C-S bond was little, because the S atom was more electronegative than the C atom, the S atom was negatively charged and C was positively charged in the molecular structure, H+ attacked the S atom and OH- attacked the C atom, this may lead to the weaker bond energy of C-S bond.
Ihe molecular structures will be changed and the viscosity will be decreased.

Nevertheless, the spiro-annulated structure caused by the 9,9′- disubstituted fluorene skeleton is of significance in polymers for optical use.
We envisioned that polymers with this structural feature can be served as an alternative candidate with not only high refractive index originating from the fluorene skeleton but also low birefringence depending on the perfect C2-symmetry of the molecular structure.

The Study on The Infrared Thermal Radiation Response of Y1Ba2Cu3O7-x Semiconducting Film De Sun School of Chemistry And Engineering, Chang Chun University of Technology No.2055 Yan An street Chang Chun, China sunde2002@126.com Keywords: Y1Ba2Cu3O7-x; semiconductor film; thermal radiation Abstract.
Our work which uses Si as substrate and includes the transition layers studies the heat radiation response characteristics of Y1Ba2Cu3O7-x semi-conducting film, and conducts the carefully theoretical study on micro-structure of the thin film. 2 The Preparation of Y1Ba2Cu3O7-x Semi-conducting Thin Film In our work, we choose Si as substrate, and prepare the semi-conducting film of Y1Ba2Cu3O7-x/Si and Y1Ba2Cu3O7-x /ZrO2/SiO2 by the method of post-annealing of direct-current magnetic control sputter.
That’s because the semi-conducting phase of YBa2Cu3O7-x is stacked up by three perofskite units which means three layer perofskite structure of hypoxia distortion.
YBa2Cu3O7-x has the simplex orthogonal structure of Pmmm at room temperature and the crystal lattice parameters are a=3.885*10-4µm,b=3.820*10-4µm, c=11.686*10-4µm .It is arranged as Cu-O, Ba-O Cu-O, Y(non-oxygen),Cu-O, Ba-O and Cu-O from the top in sequence.
It shows that YBa2Cu3O7-x semi-conducting film has many special characteristics in its lattice structure, electrical structure and film formation only when it has transition layer.

Its assumptions include: 1) Material is uniform and isotropic statistically. 2) The structure fracture is caused by the unstable propagation of the weakest unit.
Given by the Chinese “code of design of concrete structures (GB50010-2002)”, Cov decreases with the strength increasing, that is, m increases with strength.
