In our previous paper [3], the structure and electrical conductivity of (La0.6Sr0.4)(X1-yMgy)O3-δ (X= Ti, Zr, Al) perovskite solid solution were studied.
The complete substitution of Sr for La in A site lattice of perovskite structure results in the formation of SrZrO3 or SrTiO3, which is known as an insulator.
In this paper, the influence of Al content of Sr(Zr1-xAlx)O3-x/2 perovskite solid solution on crystal structure and electrical conductivity was investigated in air at 400˚-800˚C.
Most of the diffraction peaks at x = 0-0.5 were referred to an orthorhombic structure of SrZrO3 (ICDD card No. 44-161), indicating the formation of SrZrO3 solid solution.
Conclusions Perovskite solid solution Sr(Zr1-xAlx)O3-x/2 was produced in a wide composition range of x= 0-0.5 at 1000 °C and their structures were referred to an orthorhombic structure.

Correlation between lithium mobility and structure, J.
The parameters in the structure of La2/3x4/3-2xМ2O6 were used as initial [19X].

Solution treatment shows the dual structure, however, aging for 5 hours depicts the ditch structure.
Grain boundary chemistry is known to be a critical factors impacting structural reliability of austenitic stainless steels [7,8].
In general, sensitization is classified into three structures; the first is step structure which is no precipitation occurs had been observed, the second is dual structure which the precipitation had been observed but the grains are not completely surrounded by the precipitation, and the third is ditch structure where the precipitations occur with completely surrounding the grains [11].
Fig. 4(a) and Fig. 4(b) show the dual structure, however, Fig. 4(c) depicts the ditch structure observing deep and wide intergranular attack after 5 hours aging at 670°C.

Introduction Catastrophic fracture failure of engineering structures is caused by cracks that extend beyond a safe size.
The fundamentals postulate of linear elastic fracture mechanics is that the crack behavior is determined by the stress intensity factors which are the function of the applied load and the geometry of the cracked structure.
In general numerical methods must be used for the evaluation of the stress intensity factors in structures.

Environmental scanning electron microscopy (ESEM) The morphological study of the samples performed by ESEM evidenced a porous structure with honeycomb-like aspect, which varies for samples having different composition and modifies by expanding as hydrogels are swelling at increasing degree of humidity (Fig. 4).
ESEM micrographs of the hydrogel samples 99/1 NIPAAm/Alg (a) RH=20 and (b) RH=100; 75/25 NIPAAm/Alg (c) RH=20 and (d) RH=100 It can be noticed that cavities dimensions are increased at higher relative humidity RH (%) for all the samples: the pores became larger or their walls are breaking, making the structure more accessible to water vapor sorption.
Thus, the morphology of the samples is changing with increasing RH from a compact/dense structure to an expanded one.

Professor Jiang Taiyuan holds that, so called the work process is a complete work procedure carried out in business to complete a task and get the results of the task; and is a comprehensive, constantly in motion but the structure relatively fixed system.
The curriculum model based on the work process makes students obtain structured procedural knowledge, vocational skills and related vocational experience involved in the work process, which ultimately promote the formation of professional competence.

The influence of bagasse fiber on natural rubber foam cell structures is presented in Fig. 3.
The compressive behavior of the foam depended on the properties of cell structure, porosity, cell size, and cell distribution [10].
The rigid structure of bagasse fiber made the natural rubber foams stiff because cell size decreased.

The polymer PVC was selected because it is pollution free, space saving, cost effective, reliable, and flexible and its polymeric structure show good adhesion to the MM material which is responsible for the mechanical strength and performance of the composite membrane as well as selectivity of composite material.
The surface morphologies of the membrane showed a uniform arrangement of particles and the particles are irregular condensed and form a heterogeneous structure as shown in Fig. 1.

Impact strength of S1 composites was higher than the others. 3.6 WAXS study WAXS technique was used to study the crystallographic structure [13].
The broad peak at the scattering angle 2q » 16° correspond to amorphous structure of PLA.
This may be due to phase separation between PALF and PLA matrix, then PLA chain can move easily and crystallize into crystalline structure.
