It is widely reported [9-12] that with the reduction of particle size the crystal structure of the BaTiO3 is affected and BaTiO3 may loses its tetragonality in the nanometer regime (60-70 nm).
The tetragonal phase of barium titanate is characterized by a high dielectric constant due to its ferroelectric structure [2].

In order to validate our model, referring to structure that has been studied by Jay et al. [12], we have calculated the torsion hysteresis of the cantilever system in the fig. 4.
This discrepancy is due to the single domain model that has employed in our theory to predict the structure those Jay et al. [12] have experimentally studied which is exactly in the multidomain state.

This material offers advantageous characteristics including a lignin- and hemicellulose-free structure, short production time (7-14 days), and the ability to thrive in various culture media [5,6,7].
The high concentration of sugars and other essential nutrients in banana peel hydrolysates at higher concentrations provided a conducive environment for the synthesis of high-quality cellulose, with an orderly and pure structure that imparted superior mechanical and optical properties [18].

Kaolin is a commercial name of white clay containing essential kaolinite compound which has chemical structure of Al4Si4O10(OH)8 [12].
The microstructure of sample NA showed a bimodal crystal structure with larger elongated primary mullite crystals, which nucleated from kaolinite and then formed precise fine random crystals of secondary mullite.

This chemistry was chosen for stability of retained austenite, solid solution strengthening, and to prevent carbide precipitation during bainite formation [4].

The crystalline structure of TiO2 was investigated using X-ray diffraction (XRD) (Y2000, Dandong, China).
The results suggested that F-TiO2 had a better crystal structure than others.

Our previous study on ENR-50/MMT nanohybrids [11] show that by increasing the MMT in to the ENR-50, the samples possess higher d-spacing values and exhibit intercalated structure.

Kinetic Equilibrium and Adsorption Thermodynamics of Direct Dyes by Ca/CTS/FA Composite Beigang Lia*, Liwei Sunb Chemistry and Environment Science College, Inner Mongolia Normal University, Hohhot 010022, China alibg@imnu.edu.cn, b1228962507@ qq.com Keywords: Fly ash; Chitosan; Calcium ion; Direct dyes; Adsorption thermodynamics Abstract.
As a natural macromolecule polymer, chitosan (CTS) is the only alkaline polysaccharide in nature and one of the most promising organic adsorbent flocculants due to its special structure and excellent properties such as biocompatibility, safety, biodegradability and so on [7,8], but its use is limited as a single adsorbent because of its poor solubility and high price.
This indicates that the occurrence of the interaction between silicon matrix (in FA) and polysaccharide groups (in CTS) can produce an interweaving network structure, enabling CTS to be fixed on FA [13].
