Introduction Cerium oxide with a cubic flurite structure has attracted extensive attention due to its low cost, fine optical properties and high thermal stablity as well as excellent catalytic properties.
The hollow structure of cerium oxide nano powders must relate to the decomposition of ethanol in high solvothermal temperature.

Control of the microstructure and chemistry of intergranular phases is therefore particularly important.
However, this depends Crack deflection Crack bridging on the chemistry of the intergranular/secondary glassy phase (particularly the type of cations present in that).
The origin of the repulsive force is the grain boundary films structure which resists disordering.
However, it is really difficult to exactly quantify the IGF chemistry in a very narrow regime (sub nano to few nano meter).
Beneficial effect of SPS in terms of retaining nano-structure is evident from several studies.

The previous reports mostly focused on the pore structure, adsorption performance, and the formation mechanism of the pores.
The pore structure has been investigated, and the electrochemical performance has been studied in H2SO4 medium by cyclic voltammetry (CV) in detail.
Results and Discussion Structures and compositions.

Hexagonal tungsten trioxide, h-WO3 is one of the most researched tungsten oxides due to its open-tunnel structure and intercalation chemistry.
During heating this bronze, NH3 and H2O are released and a hexagonal tungsten oxide structure remains.
When 1 was heated in air, the product sample 2 showed an almost fully oxidized structure.
We measured the amount of NH4+ ions and NH3 molecules, which remained in the solid structure, by solid-state 1H-MAS NMR spectroscopy [18].

Final rolling is recommended just above the Ar3 temperature to generate a highly conditioned austenite structure, which results in fine grain microstructure on transformation and a corresponding increase in the yield strength and impact toughness [1].
During tapping, low carbon Fe-Mn, Fe-Si and Al were added in the ladle to deoxidize the steel and achieve the chemistry.
It is well known that banded structure is very common in X70 steel due to Mn and Phosphorus segregation.
Chemistry, steel making, casting and hot rolling parameters have been designed for production of X60 and X70 grade line pipe steels.
Proper design of chemistry and hot rolling parameters has resulted in very fine-grained microstructure.

The mixed phase of monoclinic scheetlite structure and characteristic peaks of silver particles were found.
It is clear that the XRD patterns of all the synthesized Ag-doped BiVO4 samples and the undoped BiVO4 are in good agreement with the standard data of monoclinic scheelite structure (JCPDS No. 14-0688) indicating that the all the prepared photocatalysts possessed the same crystal structure [4].

Nanocomposite materials are formed by mixing two or more dissimilar materials at the nanoscale in order to control and develop new and improved structures and properties.

The information contained in this book will serve both as an educational aid and as a guide to anyone involved with nanocomposites from the viewpoint of materials science, physics, chemistry, biology or medical engineering.
