The morphological structure of the synthesized MOF-5 was examined via high-resolution transmission electron microscopy (HRTEM) (JEOL JEM-2100).
These characteristic patterns correspond to the most distinguished diffraction peaks of the simulated MOF-5 structure [13-15].
The morphological structure of the synthesized MOF-5 was investigated via HRTEM, as shown in Fig. 3.

Introduction Chitosan, as the only natural basic polysaccharide with positively charges, has been widely applied in many fields such as food, medicine, chemistry and textile industry [1, 2].
Scheme 1 Reaction of chitosan biguanidine hydrochloride and hydrochloride acid Scheme 2 Synthesis reaction of chitosan biguanidine hydrochloride The intermolecular hydrogen bonds between chitosan molecules are weaken when H of –NH2 in chitosan is substituted by diguandine groups, the crystallinity structure of chitosan is then broken.
Fig. 1(a) shows the surface structure of the untreated A. pernyi silk fiber as observed under SEM image.
Likewise, Fig. 1 (b) shows the surface structure of the chitosan biguanidine hydrochloride treated A. pernyi silk fiber.

The morphology, phase structure, hardness, erosion resistance and adhesion of the electroless coating were investigated.
The phase structure, hardness, erosion resistance and adhesion were measured by X-ray diffractometer (Philips XPert), microhardness tester (XMT-101), salt spray test and scratch method, respectively.
From Fig. 1, the surface is like cellular structure.

This helps producers select the condition for production to minimize formaldehyde residue and predict the chemical structure of final product.
Although empirical models have been used successfully in simulation studies for process application, they cannot predict over the experimental condition since the elementary reactions of mechanism are unknown and they cannot offer some insights into the structures of products [8].
The infrared spectra and band assignments to chemical structures produced useful information on the structure of synthesized pre-polymers.

Transmission electron microscopy Fig.1 shows the TEM micrograph of the resulting PANI/NanoGs/Eu 3+ nanocomposites, clearly shows a novel structure with a special nanofilm of the nanocomposites, the lines represent graphite layers and other parts are PANI molecules.
The formation of this structure consists of two steps: first, aniline monomer and Eu3+ combined to form rare earth organic complexes, and then the rare earth organic complexes intercalate into the NanoGs. 3.2.
Conclusion In summary, PANI/NanoGs/Eu3+ nanofilm composite with a novel structure were successfully developed through emulsion polymerization.

The two models are considered to be the base that scholars investigate different roughness or the contact angle of micro-structured surface, and also make people raise awareness that the wettability of the solid surface is decided by the chemical composition and micro-geometry.
Micro-structure was gotten by the electrochemical way [6].
Because this hydrophobic structure having appropriate roughness and low surface energy can give a number of special properties to the surface [10], the structure has broad application prospects in daily life, national defense, and many industrial areas.

The crystal structure similarity between hydroxyapatite and octacalcium phosphate could cause the confusion and misidentification of precipitation.
Note that the definition of apatite is twofold: 1) the chemical formula of Ca10(PO4)6 X2 where X is OH for hydroxyapatite; and 2) the hexagonal crystal structure [1].
Note that OCP has crystal structure, which can be considered as the one with alternative stacking of apatite layers and hydrated layers along [100] direction [3].
