Introduction Barium titanate (BaTiO3) with the perovskite structure have been widely applied among electronic industries[1] ranging from simple sensors to multilayer ceramic capacitors (MLCCs)[2], transducers and positive temperature coefficient resistors (PTCR)[3], owing to its excellent dielectric properties: high dielectric permittivity and low dielectric loss.
The influence of the two-step calcination on the particle size and phase structures was investigated in details.
There isno impurity phase existing in raw materials, and the TiO2 employed exhibits pure anatase structure (PDF-#: 65-5714).
It is found that not only calcination temperature but also dwelling time can affect the morphology (particle sizes and agglomeration) and phase structure (tetragonality) of prepared BaTiO3 powders.

So, physics, chemistry, biology, sociology, ethics and theology, which are the classified knowledge, in this sense, can be called science.
The Thinking Structure of Narrow-sensed Science.
The thinking structure of narrow-sensed science based on axiom, mainly uses induction and reasoning to build a logical thinking system and is verified by experiments and instruments which are extended from human sense.
A system is what consists of interconnected and interactional elements and forms an integral part with certain structure and functions.
And a system has four main traits, those are, it is a combination of elements; the whole part is superior to each single one and has the character the sub-parts do not own; it has a certain structure and the sub-parts are interconnected and interactional; a system has special functions because of special structure.

Liu et al. [9] combined sol-gel and chemistry deposition to prepare a nanostructured NiO/MnO2 composite electrode that had stable electrochemical properties, but the specific capacitance was of only 453 F/g.
All tests were conducted at ambient temperature Results and Discussion The structures of the pure MnOx, Ni(OH)2 and MnOx/Ni(OH)2 composites were characterized by XRD.
The XRD pattern of pure Ni(OH)2 is shown in Fig. 1(c), combined with transmission electron microscopy analysis (not shown here), the structure of the as-deposited pure Ni(OH)2 exhibits poor crystallinity with very small grain size.
The morphology (see inset of Fig. 2(a)) is quite different from the reported fibrous structure produced by anodic deposition in Mn(NO3)2 solution [13].
Further increasing the concentration of Ni (NO3)2 in the mixture of electrolyte, the network structure composed of the interconnected nanowebs becomes thicker and denser, shown in Fig. 2(c).

The crystal structure and surface morphology of as-prepared samples were measured by Bruker-D8 Advance diffractometer with Cu Kα radiation and scanning electron microscopy (SEM, QUANTA FEG450).
Results and Discussion As can be seen from XRD patterns of Co-Lax-B alloys shown in Fig. 1, there is a very broad diffraction peak appearing at 2θ = 45º in each pattern, indicating that the as-prepared alloys are in an amorphous structure, which agrees with the published results [3,11].
Therefore, the different atoms cannot arrange in a certain crystallographic direction and then disorderly stack, thus forming an amorphous structure [18].
It may result from the different growth rate of different atoms in the three-dimensional structure after the addition of La [18].

For the 1H-NMR data [Fig. 1(a)], observed chemical shifts were found to be consistent with the structure of MIMOAc as indicated by the numerical assignments in the figure.
Furthermore, the number of protons obtained from the peak integration matched with the theoretical number of protons based on the structure of the desired product.
This was further verified by the 13C-NMR data [Fig. 1(b)] in which the number of peaks observed is equivalent to the number of carbons in the structure of MIMOAc.
The presence of these vibrational modes suggest that we have covalently incorporated MIMOAc in the structure of the PAN backbone.

Because the resin contains both polyhydroxy and triazine ring structure, it has dual function of charring and foaming.
Structural Characterization of Charring Agent The structure of MF-MPOL was characterized by FT-IR, solid-state 13C NMR.
Compared with the residue of FR-PP, although the residue of PP has smooth and compact structure, but its amount is very little (about 0.5%) and no intumescent char layer is formed , which brought about poor flame retardant effect.

In this way, sonochemical synthesis allows the major control of crystalline structure, size and morphology of particles [11].
Characterization Methods Crystalline structure of TiO2 samples was identified by X-ray powder diffraction (XRD) on a Bruker D8 Focus X-ray powder diffractometer operating in the reflection mode with Cu-Kα radiation (35 kV, 25 mA).
Below 550 ºC, the principal crystalline structure was anatase and no other phase is detected within the X-ray detection limit (no showed herein).
At 900 ºC the main crystalline structure is rutile.

It is reported by various authors that the nature of the anions affects the PAni structure [10, 14].
Two different types of PAni morphology in oxalic acid electrolyte were mainly observed; the fibre and the nodular structures.
As can be seen, the morphology of PAni in pH1.55 is fibre form, while the nodular structures were observed in pH 2.53, 3.5.
The morphology of synthesized PAni at 0.03Vs-1 is between the fibre and the nodular structures.

Analysis of resin and pigment disposal mechanism shows that different resin has different chemical structure which may differ in the affinity to the pigment surface modifier [10].
When the ink is exposure to the external force, the inner structure will be damaged, and the links between the pigment and binder become weak, which give the resin molecule freedom to move.
This might be the cause of different samples having diverse binders which have different condensed structures.
Different types of resins, due to their different chemical structures, differ in the adhesion between ink resins and the substrates.

The growth of crystal structure from polymer solutions is found in polymers crystallized from the melt [19].
The number, size and fine structure of spherulites depend on the temperature of crystallization.
This means the large structure form near Tm whereas greater number of small spherulites grows at lower temperature near Tc.
Zhijiang and coworkers [22] were expressed that PHB crystallizes in an orthorhombic lattice structure.
