The FTIR study displays that the chemical structures of SCNW are consistent with those of cellulose, indicating the removal of most of hemicelluloses during the acid hydrolysis process.
Fig.1 Structure of cellulose crystalline Over the last decades, the chemical modification of cellulose hydroxyl groups has facilitated the expansion of its applications including paper, packaging films, pharmaceuticals, food and textiles [11-13].
The above results indicate that chemical structures of SCNW are consistent with those of cellulose.

After annealing the Ag-SiO2 powder at 873 K the TEM study suggested that the silver had crystalline structure.
The XRD studies confirmed that silver appeared as a FCC crystal structure.
The structure of the Ag was studied further with the XRD and UV-vis.
The weight loss probably occurs because of the densification of the silica structure.

A composite structure based on silylated MCM-41 and Poly(vinyl acetate) (PVAc) was synthesized via solution intercalation.
When the silicate layers are completely and uniformly dispersed in a continuous polymer matrix, an exfoliated or delaminated structure is obtained.
In such composites, the repetitive multilayer structure is well preserved, allowing the interlayer spacing to be determined.
The existence of peaks due to C=O and C-O stretching at 1729.1 cm-1 and 1234.4 cm-1 (Fig. 4 (a-d)) indicating the acetate structure of PVAc [6].

At a magnification of 5000x, the copper hydroxide particles exhibit a crystalline structure with rough, uneven surfaces and varying dimensions.
At pH 11, the particles form elongated crystals with slightly pointed ends, indicating a more structured and defined morphology.
As the pH increases to 13, the particles take on an irregular crystal structure, displaying less uniformity in shape and size.
SEM analysis confirmed that the morphology of Cu(OH)2 particles varied with pH, with well-formed crystalline structures observed at pH 11 and 12.

Niobium (Nb) is a metal with 2468°C melting point, density 8.57 g/cm3 and CCC crystalline structure [2].
The CCC crystalline structure materials submitted to plastic deformation tends to present a linear hardening work in high reductions (e), opposite of CFC crystalline structure [17].
It can be observed the typical recrystallized structure formed by different grains sizes.
This is common in materials of CCC structure that in high reductions don’t show saturation.

Pure core and core-shell structures were confirmed by TEM.
The core-shell structure was not produced using seed emulsion with emulsifier concentration at or below the critical micelle concentration.
Transmission electron microscopy (TEM) confirmed the core-shell structure (Fig.2(a) and (b)).
In summary, It is possible to synthesise core-shell structured latex with poly(VAc-co-VeoVa10) core and poly(glycidyl methacrylate) shell.

BLT ceramics have a structure based on ABO3–type perovskite, and its properties strongly depend on the chemical composition.
The defect chemistry of undoped and doped BaTiO3 has been widely studied [2–5].
X-ray diffraction method was used for characterization of the ceramic samples in terms of its crystalline structure.
The X-ray diffraction analysis was performed at room temperature and formation of the desired crystalline structure has been confirmed.
A model structure used for the diffraction pattern fitting exhibited a P4mm space group (SG number: 99) (Fig.2) [8].

Adsorption Behavior of Methylene Blue with Quaternary Ammonium Modified Chitosan Microspheres Resin Xingmei Guo, Yufei Chen, Qiuyun Zhang, Lixuan Zeng, Jiwen Luo* Key Laboratory of Theoretical Chemistry of Environment, Ministry of Education; School of Chemistry and Environment, South China Normal University, Guangzhou 510006, China Key words: chitosan, rectorite intercalation, quaternary ammonium, adsorption, methylene blue Abstract.
It contains hydrogen bond and ionic bond, which can form a cage-like molecular network structure and thus it has a strong adsorption.
Besides, their structures were observed by using the X-ray diffraction (XRD) and Fourier transform infrared (FT-IR).
Because of its structure, it has strong interface adsorption and cation exchanges which make it become a good raw material for adsorbent preparation [15].
