Introduction In recent years, simulation enzyme is always the hot topics in the study of scholars, because the natural enzymes is complex, expensive and of unstable structures.[1] With complex and more stable chemical structure, these mimetic enzymes have similar catalytic function to natural enzymes.
NiR Figure 1 Structure of the complexes Kinetic method The apparent first order rate constants (kobsd) of BNPP hydrolysis were obtained on the basis of the initial rate method, according to the equations: (rate)0 = -(dA/dt)0/ε = kobsd[NiR]0, where (rate)0 is the initial rate of BNPP hydrolysis, [NiR]0 is the initial concentration of the complex.
Phosphoric acid and p-nitrophenol should be generated when NPP is hydrolyzed in accordance with its structure.

The type and structure of the fibers are also a factor of the absorption.
Some natural fibers are favorable for oil absorption due to their structure, such as hollow fiber.
This is due to the structure and nature of these two types of fibers.

The antioxidant activity of procyanidins is much higher than that of VE and VC due to the presence of phenolic hydroxyl in their molecular structure.
The benzene ring structure exists because the vibration of the benzene ring skeleton of procyanidins also changes at 1611cm-1, 1518cm-1 and 1448cm-1, indicating the formation of complex.
The conjugated structure of A and B rings of procyanidins makes the absorption intensity of their maximum absorption wavelength higher.

As shown in Figure 4, the reaction could not proceed completely and the network structure could not be completely utilized to form when the radiation time is too short, this lead to a decrease in water absorbency.
When the irradiation time is too long, the network structure is destroyed, it maybe another reason that result in the decreasing of water absorbency.
As shown in Figure 5, on the one hand, the temperature will increasing quickly when the irradiation power increased, thus the SAR partly be rigescent and the network structure of SAR would be destroyed.
Just beginning, with the increasing of OMMT, the network structure is formed, which enhanced the ability of water absorbency of SAR.

The process enables the host particles to have a multi-coating layer, and form different nanometer or micrometer-level fine structures on their surfaces[1].
Figure 1 SEM photographs of ACB/UHMWPE composite particles with 1%ACB (a, b, c) As indicated by SEM micrographs, the UHMWPE particles are coated with rich ACB -containing layers, resulting in a core–shell structure.
It suggests that the conductivity of ACB/UHMWPE blends is the consequence of a hierarchical conductive structure, the conductive paths within the matrix interconnect the ACB-covered UHMWPE particles.
This unusual ACB distribution results in unique structures with interesting electrical and thermoelectric properties, due to the networks which are difficult to be destroyed by thermal expansion.

The stability of spinel structure improves while Cr-doped smoothly enter the 16d position of the LiMn2O4.
It showed that the crystal structure of the prepared cathode material didn’t change by coped Cr.
Because the bond energy of Cr-O is stronger than that of Mn-O, doped Cr can reduce Mn3+ content of spinel, thereby inhibiting the Jahn-Teller effect, stabilizing the frame structure of spinel [14].
It illustrates lattice contraction occurs, the structure is more stable.
Which is due to Cr-O bond is stronger than Mn-O bond and the Cr-doped samples can still maintain the stability of the structure after many charge-discharge cycles [15].

Introduction Dynamic properties of elastomer materials are very important for the determination of their structure, as well as the prediction and design of rubber product properties [1].
Three reinforced composites with three silica fillers of different structure and surface properties and an unfilled one (gum) were used for this study.
It follows that the change of structure, resulting from corresponding treatment, causes the same change of behavior in both regions but to different extent for elastic and loss moduli.
The organization of its aggregates to rather large agglomerates, the increase of macro- and meso-pores of aggregate structure and generally much more complex morphology can be observed.
Depending on the type of silica used, not only morphology of silica aggregates but also surface chemistry inside and stressstrain properties of vulcanized rubber can be varied.

Molecular structure of Benzotriazoles Intramolecular hydrogen bond (IMHB) chelate ring can form in benzotriazole ultraviolet absorbers[2], which is the structural basis for energy dispersion[3].

Compared with BTA, the broad smooth band of BrBTA moves higher to 3431 cm-1, which might be on account of the tautomeric interconversion of keto-enol that the structure of BTA mainly presents keto form while BrBTA enol form.
