Because ofthe instability of the originally dispersed sol, a large number of colloidal particles precipitate.Colloidal particles connect with each other by the vander Waals force forming a reticular structure.
And the alcohol molecule liesin the interstices of the mesh structure and is bound to the mesh three-dimensional skeleton gap of the sodium stearate connected to each other, and has formed the solidified alcohol which is a colloidal gel state.

All of the coatings exhibit dense structure free of pores.
The dentritic structures contain a Ni rich solid solution and within the eutectic niddle-like structures with Cr rich phases (grey areas) confirmed also by the EDX analysis.
The average micro-hardness of Sample 2 and 3 exhibits increased values above 500 HV0.3 which can be mainly attributed to the formation of fine and homogenously distributed needle-like shape structures rich in Cr.

· It has been found that as the laser power increased needle-like shape structures rich in Cr were formed within a complex eutectic mixture

By doping with 1 mole %, the structures became denser with less pores formation compared to the undoped sample.
The changes in lattice constant indicate that the Li+ influence the NiO structure.
The crystal is change from monoclinic to cubic structure after added with Li+.

Schematic view of the sample cross-section of a BG-JBS diode structure.
Electrograph of the sample cross-section of a BG-JBS diode structure.
The top 2 μm thick n-type layer has been epitaxially re-grown by using silane-propane chemistry, incorporating nitrogen dopant atoms.
Cross sections of cleaved BG-JBS structures in 4H-SiC were investigated after a solvent based cleaning process followed by an UV-ozone treatment.
Interestingly, additional features at the border of our structures have been observed.

The small fibre diameter and the porous structure of the electrospun surfaces enable them to be applied in a wide range of applications such as filtration, enzyme immobilization, electrochemical sensing, composite materials, reinforcements, bone and blood vessel engineering and tissue engineering [12-13].

XRD, SEM and UV-Vis absorption so the samples X-ray diffraction patterns were used to investigate the composition and phase structures of the as-prepared samples.
This indicates that all samples are hexagonal wurtzite structure, and the composition of WO3 does not influence the crystal structures of ZnO.
It has been reported that only the hexagonal wurtzete structure ZnO shows good photocatalytic performance when irradiated with UV light.
So it is necessary to keep the hexagonal wurtzete structure invariant after WO3 compositing.

This increase is proportional to the structural units SbTe3/2, which are built into the glass structure by breaking the Se-bridges by the scheme, presented on Fig. 2.
The structural units – Cd – Te – also built into the glass structure by breaking of Se-bridges: – Se – Se – + – Cd – Te – → –Se – Cd – Te – Se –.
This approach leads to densification of the structure with the increase of the CdTe content at m=0.05.

It has low activity and fine grain so that it reduces the continuity of the inorganic polymer network structure which affects the strength of the specimens.
Considering the microscopic structural characteristics, ordinary concrete specimen contains a large number of capillary channels so that the structure is not density enough.
Therefore, fly ash can reduce the continuity of the inorganic polymer network structure.
