This can be achieved by applying increasingly sophisticated models to predict the microstructures and properties of novel chemistries and processing routes.
Firstly the structure of the model is described, then the model predictions concerning micro-chemistry are discussed and compared with the observed microstructures. 2.

After two hours of heat treatment at 600 °C, XRD was employed to validate the cubic crystal structure of NiO-NPs.
Plant extracts are also used in green chemistry as a reducing and protective approach [13].
In addition, It is possible the results were attributed to the cubic NiO structure, also known as "Bunsenite" [17].
Nano-sized particles were seen on the surface in the form of large aggregated particles, indicating that the structure is aggregated.
As per the XRD analysis, the NiO-NPs synthesised and annealed at 600°C for two hours have a cubic structure with a crystallite size of approximately 24.40 nm.

The chemical structure of BC produced was studied using Fourier Transform Infrared Spectroscopy (FT-IR) and X-ray defections.
All bacterial celluloses obtained in the different experiments were characterized in terms of molecular weight, morphology, crystallinity, and structure.
High-Medium-Low, respectively) using OPSJ and coconut medium were characterized in terms of their chemical structure, morphology and thermal properties by FTIR, XRD, TGA, and SEM and (Fig. 2A, 2B, 3, and 4), respectively.
Other bands at 1375 cm−1 (C-H bending), 1335 cm−1 (O-H in-plane bending), 1315 cm−1 (C-H2 wagging), 1277 cm−1 (C-H bending) and 1225 cm−1 (O-H in-plane) indicate the presence of crystalline regions within the structure [9, 10].

Wet-chemical processing and angle-dependent optical properties characterization of mica/TiO2/Al2O3/M2O3 (M = Fe, Cr, Co) pigments Haiyan Du, Caixia Liu and Jiayue Suna College of Chemistry and Environmental Engineering, Beijing Technology and Business University, Beijing 100037, China ajiayue_sun@126.com Keywords: Pigments; Mica titanium; Coating; Angle-dependent optical properties Abstract.
The optical effects of four-layer structure pigments were investigated in detail by using the five angles’ spectrophotometer.
So the mica titanium may present the special hollow structure, which in turn leads to the enhanced angle-dependent effect.
That’s to say, the multilayer structure materials should be designed and prepared.
The crystal lattices and basic structures of all the angel-dependent pigments keep invariable during the wet chemical precipitation process.

XRD pattern analysis showed that the ZnO nanorods are the hexagonal structure (space group P63 mc).
Hydrothermal synthesis, as an important method of wet chemistry, has attracted lots of attention from materials scientists and chemists.
All the diffraction peaks can be indexed to wurtzite structured ZnO (space group: P63 mc, a = 0.3249 nm,c = 0.5206 nm, JCPDS card No. 36-1451).

The calcined HA particles were characterized by X-ray diffraction (XRD) for their crystal structure and particle size analysis.
Sample characterization : The crystal structure of the calcined HA powders were analyzed by X-ray diffraction (XRD: D500; siemen company, US) with CuKα radiation λ=0.15406 nm at accelerating voltage 40 kV and current of 30 mA.
