However, there are critical limitations in applying the HA to real systems because of its poor mechanical properties [3].
On the other hand, zirconia (ZrO2) possesses excellent mechanical properties.
We studied the structural, mechanical properties, and phases of the scaffolds prepared under various processing conditions.
It can be seen, as the HA-ZrO2 concentration was increased, the pores became interconnected with more dense and thicker pore walls, which are important factors that improve the mechanical properties of the porous materials.
Clearly, the mechanical properties of porous HA-ZrO2 scaffolds are significantly affected by the concentration of the ceramic powder in the slurry and doped with 20% ZrO2.

Introduction The integrity of the horizontal wellbore directly affects the progress of shale gas development and the economic benefits of shale gas fields.
The rock mechanics properties of the Fuling area are shown in Table 2 [2].
Previous studies have suggested that formation heterogeneity is the main factor affecting casing deformation; elastic modulus and Poisson's ratio are one of the main means to characterize formation heterogeneity; elastic modulus increases with the increase of formation depth.

Recently, in order to ensure stable line operation and to predict its span of life, the changes of thermal properties for STACIR/AW have been investigated.
In the present work, the changes of strain with temperature and the creep behavior as important factors in sag control will be presented.
Since the STACIR/AW operates at high temperature ranges, it is quite necessary to evaluate the aging properties of component materials.
In the present work, among the results of detailed resent researches on STACIR/AW, the strain change with temperature and the creep behavior as important factors on the sag control are briefly described.
The mechanical load for tensile test of STACIR/AW was 20% of UTS.

This study aims to investigate the effect of processing routes (A and Bc) and temperature on microstructure, texture and mechanical properties of pure magnesium was studied in this research.
To overcome these drawbacks, grain refinement has been used as an attractive solution to improve the mechanical properties of magnesium.
The improvement of mechanical properties of pure magnesium strongly depends on grain size as well as texture [1,2].

The electrical resistivities (ρ), compressive stresses (σ), and longitudinal strains (εl) of these cured nanocomposites under cyclic uploading/unloading were simultaneously collected, to characterize their stress/strain-sensitive properties.
As for the smart function of CNT-based cement composite, Li et al [10], Luo et al [11], and Yu et al [12] have successively reported the good stress-sensitive properties of cement matrix filled with small amount multi-wall CNT (MWNT).
Its main physical properties are listed in Table 1.

As known, the main factors affecting the conductivity of composites are the contact resistance and the number of conductive netlike pathways.

Many researches have already been done on the investigation of crack propagation and mechanical properties under various factors in single or polycrystal metal materials.
However, the effect of temperature on mechanical properties was not explained.
Another two factors which affect the crack propagation mechanism and mechanical properties are temperature and strain rate.

From the results, the gauge factors for piezoresistance and piezocapacitance can reach up to 153 and 224, respectively.
Therefore, these nanostructures have suitable stability properties that allow them to act as sensing elements for MEMS sensors based on the high piezoresistance and piezocapacitance methods.
The piezoresistive sensitivity factors have been calculated using the equation .
With their high gauge factors of 153 and 224, these Ag nanocomposite films can act as sensing elements in MEMS sensors, strain/stress gauges or pressure sensors.
