The structure analytic results showed that all the prepared powders are well crystallized.
In this work, we report the effect of the various hydrothermal temperatures on the structure of BaTiO3 staring from a mixture of Ti(OBu)4 + BaCl2.
It is obvious that the reaction temperature has a remarkable effect on the crystal structure, i.e. increasing reaction temperatures will cause continuous crystal cell variation.
Table 1 shows the structure parameters of the prepared BaTiO3 nanoparticles.

Results and Discussion Preparation of the Bead with Core-shelled Structure.
The fabrication strategy for the bead with core-shelled structure was shown in Fig. 1.
Fig. 2 has showed the structure of the beads after preparation.
The two different drug release behaviors completely rely on the specific structure of the hydrogel.

Results and Discussion Morphologies and Structures of Zinc Phosphate Fig.1.
In brief, when the polymer was used as template, the assembled structure can be easily obtained.
In brief, when the polymer was used as template, the assembled structure can be easily obtained, while simple structure is formed with monomer as template reagent[15].

The quantum chemistry computation was carried out by B3LYP6-311G (d, p) of Gassion_03 Program.
Its stabilized structure is shown in Fig.1.
The structure is responsible for the properties as low melting point, forming order structure as inducer and changing the surface tension of the casting solution as a surfactant.
Compared with the pore structure in Fig.2(b), the PSf membrane still has asymmetric finger structure, but the surface layer is thicker rapidly than that of the membrane in Fig2.
When the ionic liquid/NMP ratio increase to 15:65, the structure of the PSf membrane is sponge-macrovoid structure, the macrovoid is drawn out and stop close to bottom of membrane.

Structural examination, such as X-ray diffraction (XRD), transmission electron microscopy (TEM), and nitrogen (N2) adsorption and desorption, showed the activated rice straw-derived biochar‘s distinct crystal structure, morphological structure, pore structure, and surface area.
Rice straw-derived biochar revealed an amorphous structure, nanosheet-like or multilayered morphology, and hierarchical pore structure.
Then, the relationship between the structural properties of RS-derived biochar, such as pore structure, surface area, functional groups, morphological structures, and the electrochemical performance in supercapacitors, was examined. 2.
The functional groups contribute to the surface chemistry of ARSB and improve its electrochemical performance.

Measurements of the stationary current-voltage characteristics have shown that the structures obtained have a slight rectification K.
The effect of heat treatment time on the photosensitivity of isotype structures is shown in Fig. 2 b.
A similar feature is observed in the preparation of anisotypic structures.

Activated carbon, activated alumina and silica gel have no ordered crystalline structure and are characterized by heterogeneous porosity.
Adsorbents 1-2 with a specific capillary-porous structure (Fig. 2-3) have better adsorption characteristics than samples 3-4.
Adsorbents 1, 2 with features of the surface structure have better diffusion characteristics than adsorbents 3, 4.

The XPS analysis results showed that carbon was doped into TiO2 particles and one kind of carbonate species with Ti-O-C structure was formed.
Our results belong to the latter [4-6]: the doped carbon substituted some lattice titanium atoms and formed one kind of carbonate species with Ti-O-C structure, which induced the narrowing of the band-gap and the response to visible light.
XPS survey spectrum revealed that carbon atoms substituted for some of the lattice titanium atoms and one kind of carbonate species with Ti-O-C structure was formed by the substitution.

The structure, morphology and elemental analysis of CuO nanostructure were analyzed by field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS).
For determine the size, atomic structure and chemical composition of the CuO nanostructures, the Field-emission-scanning electron microscopy (FESEM) and Energy dispersive X-ray spectrum analysis (EDS) were carried out on a FEI/Quanta 450 FEG.
This may be due to the removal of more H2O vapor from the structure of CuO nanoparticles [11].
