The structure and morphology of spheres were quantitatively investigated by Zata potential and particle size analyzer, N2 sorption isotherms, XRD, SEM and TEM.
This preparation method provides a new synthetic strategy to control the particle morphology and structure simultaneously, meanwhile this method can also significantly reduce the cost of synthesis of mesoporous silica microspheres.
Therefore, it is still a big challenge for researchers to control the particle morphology, size and the pore structure simultaneously and independently.
Using higher magnification to observe their internal pore structure, as shown in Fig. 4c, the spheres exhibit worm-like (point out by white circle) poorly ordered mesopores.

The effect of thermomechanical processing on the structure and mechanical properties of the alloys is analyzed.
Note that similar structures were found in the alloys with a lower concentration of interstitials – 0- 1 at.% of С and 0.5-1.0 at.% of N.
However, note that the chemical composition of the fcc matrix was different in the cases of the C/N-doped alloys and the chemistry of the matrix can affect (a) (b) Fig. 3.

Temperature dependences of conductivity GDC for sample with Ge NCs (curve 1), structure with Ge nanoislands modified by deposition of 8 Si MLs on the structure with Ge nanoclusters (curve 2) and reference SiO2/Si structure without NCs (curve 3).
For instance, we get = 1.18×109 cm-2еV-1 for the structure with Ge NCs and at = 1.47×109 cm-2еV-1 for structure covered with 8 Si MLs at frequency 1 MHz.
The Ge-NC/SiOx/Si structures have more complex electronic spectrum as compared to well-known SiO2/Si or Ge/Si structures due to the presence of heterogeneous silicon oxide films.

The ASO-2 film relatively exhibits a non-homogeneous structure and uneven morphology in its AFM images.
Atomic force microscope (AFM) provides a possible way to investigate the film morphology and the precise structure of functional polysiloxanes on molecular scale.
Therefore, the combination of IR and 1H-NMR indicates that ASO-2 possesses the expected chemical structure shown as follows.
Comparing Fig.4 with Fig.5, it is distinctively discovered that ASO-2 has formed a non-homogeneous structure film on the silicon surface.

N2 sorption analyses demonstrated that OCNT possesses typical mesoporous structure and centralized mesopore distribution.
Results and Discussion The pore structure and surface properties of Maxsorb and OCNT.

It is believed that the ordered 2D hexagonal structure of OCNT and its larger pore size favor the ionic penetration into its pore structure.

The collagen component of bone can be reduced and remain its inorganic constituents and a porous structure.
The porous of β－TCP has several advantages: natural pore structure to avoid damaging the space structure of natural bone , natural trabecular structure, bone trabecula, trabecular space and bone internal lumen system.
The optimal bone substitute is one with a composition and a structure similar to that of human bone tissue.
The present vesicular structure of combined artificial bone can be considered that the beehive-shape structure in the β-TCP was remained (figure 5d).
To better know structure of β-TCP, the porosity of β-TCP was studied (figure 6).

The simulation results by MD-PCM-UAS yield a liquid-like structure.
The specified crystallographic data for the NiTi2 structure was acquired from a database [13].
Hence, MD-PCM-UAS has possibility to produce a liquid-like structure for Zr2Ni alloy.

The sol-gel's nanocrystalline grain structure results in improved mechanical properties of the coating [1, 2].
This process involves the conversion of the rutile structure of the original titanium oxide into a mixed rutile and crystalline anatase structure.
Secondly X-ray diffraction provides evidence of the amount of the rutile phase being reduced, but show only small peak matches of the anatase structure pattern, indicating there is some evidence of the anatase structure being formed.
As all HAp coatings were the same crystal structure and composition it appears that the crystal structure of the anodised layer plays a vital role in this increase.

Properties of X80 Pipeline Girth Welds For Different Welding Procedures Xiaodong He1, a, Ke Tong1, b, Minghua Liang1, c, Lixia Zhu1, d, Weiping Lin1, e 1CNPC Tubular Goods Research Institute, China ahexiaodong002@cnpc.com.cn, btongk@cnpc.com.cn，cliangmh@cnpc.com.cn, dzhulx@cnpc.com.cn, elinwp@cnpc.com.cn Keywords: X80; pipeline; girth welds; welding procedures; structures and properties Abstract: The X80 girth welds were produced by solid-wire gas metal arc welding (GMAW) and shield metal arc welding (SMAW) using two welding consumables respectively, which contained different mass fraction of C, Mo and Ni.
There are obvious differences in chemistry between the welds produced by GMAW using ER 90S-G and ER 80S-G.
The optical micrographs reveal the predominantly columnar as deposited weld metal structure.
And the IAF structures formed in the GMAW-N and SMAW-N welds were generally coarser compared to the GMAW-B and SMAW-N welds.
Micrographs of welds and fusion zones for SMAW Conclusions This experimental investigation provides data on the mechanical and structure properties of X80 pipeline girth welds produced by GMAW and SMAW.

The more anisotropic structures are formed, the larger their size, the denser the contact between the "grains" of the structure – the lower electrical resistivity.
Anisotropic coke structures can be considered as a single macromolecule – a cluster; they have a structure close to the graphite crystalline structure [19].
That is, the coke resistivity depends on all its structure levels.
The carbonized residues structure ordering occurs in the direction of molecular structures becoming aromatic [22].
