The structure converted into a nearly amorphous semicrystalline structure after the calcination process (Fig. 2b).
As a result of the molding, the granular structures entered into each other to form a flat surface while any significant change on the nanorod structures wasn’t being observed.
At this high temperature, nanorod structures are disappeared (Fig. 2d).
After the sintering process, the nanorod structures have disappeared and the crystal structure appears to be fused on a very wide surface (Fig. 3d).
There was not any droplet formation or aggregation in the structure.

Combined with immunostaining methods, TEM images can distinguish some specific structures in nerve tissues [21].
In nerve tissue engineering, CLSM offers excellent possibilities to control the depth of field of scanning for monitoring fluorescent-stained neuronal structures at sub-micrometer resolution in 3D structure environments.
The variation of the porosity along the thickness of the scaffolds for the two analyzed structures is represented in the graph (C).
They provide an excellent non-destructive and non-invasive method for analyzing the structure of engineered scaffolds.

And the fracture mechanism of the exposed specimen with this special structure would also be discussed.
In the last two decades substantial effort has been done to improve the ductility of this class of alloys by chemistry modification and microstructure control, and certain successes have been made [2,4].
Actually, there were other two types of crack including type-Ⅰcrack and type-Ⅲ crack in fully lamellar structure in Fig.4.
This was not consistent with Thomas’ study on the near-gamma structure.
In this work, all test specimens had uniform microstructure (almost identical lamellar orientation), and the directional lamellar structure possessed much higher resistance to crack origination and propagation than the near gamma structure when loaded parallel to the lamellar boundary.

The prepared hybrid TPPH presented amorphous phase, exhibiting a hierarchical macroporous structure composed of mesopores with a pore size of 2.0 nm.
By doping organophosphonic acid or phosphoric acid, typical hierarchically meso/macroporous structures were obtained, which are shown in Fig. 1.
For the hybrid TPPH material, a large number of alveolate macropores with openings ranging from 90 to 400 nm spread over the entire structure (Fig. 1c).
UV-vis diffuse reflectance spectroscopy was performed to assess the optical properties and electronic structure of the hierarchical TPPH.
The fabrication of other titanium/titania phosphonates with different organic bridging groups and hierarchical porous structures can also be expected.

This kind of electrode has a good prospect in analytical chemistry and sensor technology [2].
The films prepared by electrochemical sol-gel method have compact structure.
For electrode using in electrochemical analysis, the pore structure is the key factor.
So, some researchers are working on methods for controlling pore structures.
In addition, a trumpet shaped hole structure was prepared [32].

Fig. 2 shows the many kinds of organoclays, categorized according to their chemical structure and modification procedure [67, 68].
With a CaO/Al2O3 ratio of 1.0, a crystallization time of only 24 hours, and a high crystallinity of 95%, the calcium-modified NaY zeolite was successfully created, as validated by advanced characterisation methods With a specific surface area of 321.1 m²/g and a pore width of 1.139 nm, this zeolite demonstrated a microporous structure.

But because of the great changes in the fuel structure in the countryside, and owing to the substantial decline of manufactures made of straw, a great amount of straw is burned on the side of field and road.
So the adaptation of product structure of flame retarder is continuously made to deep the research on efficient eco-friendly flame retarder.
