So 8-Hydroxyquinoline and its derivates are of the most intensively investigated ligands in the coordination chemistry [12, 13].
Ltd., China) with average particle size of 5 nm (as shown in Fig.1), 8-HQ (A.R., its molecular structure is shown in Fig.2) and anhydrous alcohol (A.R.).
Fig.1 TEM photo of γ-Al2O3 nanoparticles Fig.2 The schematic structure of 8-HQ molecule Four aliquots of 0.5 gγ-Al2O3 nanoparticles were firstly added into four beakers, and then mixed with 20ml 8-HQ alcohol solution of 10-3, 10-2, 5×10-2 and 10-1 mol/l, respectively.

Hydrothermal methods have important advantages in the manufacture of nanopowders [3, 4] such as: one-step process, low synthesis temperatures, producing materials with a nanocrystalline structure, controlled homogeneous composition and high sinterability.
Al2O3 with bohemit crystalline structure has been hydrothermal crystallized onto cubic zirconia nuclei dispersed in the solution in order to obtain a core/shell composite nanostructured powder, as revealed by XRD paterns (Fig.6).

Hydrogel is a network of hydrophilic polymer that can swell in water and hold a large amount of water while maintaining the structure.
The stimuli -sensitive hydrogels are also called ‘intelligent’ or ‘smart’ hydrogel, and can control drug release by changing the structure and properties of the hydrogel [3].

The properties of varistors result from grain boundary phenomena, so the grain boundary chemistry and the homogeneity of dopant distribution at the grain boundaries are critical.
Finally, multilayer varistors were made having the same geometric structure with MLCC.
The chemical homogeneity of specific dopants and the ceramic micro- structure play an important role in the electrical properties of varistors.

In addition, during seed germination process, high oil concentration destroyed seed internal structure and baffled the transformation of nutrients with the absorbing water, which affects the germination of seeds.
Another one may be come from the physiological structure of rice seed, which need more study futher.

It is expected that the performance of boehmite and alumina particles as the coatings and fillers is strongly dependent on the characteristics of the particles used, namely, the morphology, size, length, crystal structure, etc. [5,7].
This seems to reflect that fibrous particles form the film and coating with dense structure, compared with plate-like and rod-like particles, in other words, boehmite nanofibers over 500 nm in length tend to orient in parallel to each other and densely aggregate [8].

Herein, we report the structure, morphology, and flexural strength of these novel materials.

However, there were numbers of irregular grains, compact structures and different shapes at three different time duration.
In addition, the transmittance mainly depended on the film thickness, grain size, grain distribution and morphological structure.

Due to the difference in chemical composition and structures, different natural dye extracts show different absorption ability in the visible to near infrared region which confirmed by the studies elsewhere [5,6,7].
However, further research needed to be done to confirm chemical structures and composition for the natural dye extracts.

In chalcone compounds, unsaturated carbonyl group (C=O) acts as an electron withdrawing group, an electron-rich substituents on the phenyl group acts as an electron donating group, and the structure of the D-π-A is formed inside the molecule.
Chalcone and its derivatives have a wide range of applications in medicinal chemistry, biological probes, chemical sensors and other fields for its diversity and uniqueness of physiological activity photophysical properties.
Different yields were achieved due to different aldehydes structures, different experimental conditions.
