The Sr doped La2Zr2O7 powders in pure pyrochlore structure were produced using this approach.
Hence, with the proper control of its localized structure formation, pyrochlore phases can offer improved performance of fuel cell systems.
Finally, another application of the LZO structure includes using the LZO as a solid electrolyte in the proton conducting membranes of SOFC’s.
An X-pert Pro X-ray Diffraction (XRD) System (Panalytical, Netherlands) was used to characterize the crystal structure of the synthesized powder.

By selecting the same surfactant triblock copolymer Pluronic F127 (EO106-PO70-EO106) as structure-directing agent, films with different pore structure and similar aperture size were synthesized under different conditions.
The results clearly showed that pore structure control of mesoporous film was an effective way to improve sensor performance.
After 60 s, the quenching percent show: 40.52, 57.39, 52.72, 2 D hexagonal films couldn’t catch up with the 3 D pore structure films; After 120 s to 1200 s, the 3 D order cubic structure film shows higher and higher quenching intensity than the other two films.
Sizeable films with 3D order cubic channel structure exhibited a rapid response to explosives.

Many studies have indicated that developing a porous structure in biomaterials is a strategic feature for successful bone restoration [17–19].
Elemental analysis of the surface chemistry of the prepared samples (C0, C1, Z1, and CZ) was conducted using EDX, as demonstrated in Figure 2.
This means that supplied titanium substrate possesses an extraordinarily high degree of cleanliness and purity, and that the manufacturing process didn’t alter its surface chemistry.

The joints display a wide variation in chemistry and phases present in the fusion zone as well as the ‘Heat Affected Zone’(HAZ) having significant influence on the properties and structural integrity of the weld joints.
The microstructure of the welded specimen sectioned at 20mm away from weld centre is comparable to that of the base metal structure.
The joint with ER630 filler wire had solidified in the ferrite form and during subsequent cooling attained the austenite –martensite structure [9].
This structure caused the reduction in hardness of the weld bead (~200HV) as compared to the wrought condition of 15-5PH (~365HV).
Higher hardness in the HAZ on both sides could be attributed to a recrystallised structure.

Electrospinning was chosen as the fabrication method because it is a simple traditional technique that is capable of manufacturing nano sized structures in a large scale.

The structure and chemical components distribution of the coating can be controlled by process parameters and the general quality of coating is good.
Coatings on Ti substrate generally have a porous structure and the coating process is highly efficient.
Covalent attachment, such as silane chemistry, self-assembled monolayers and plasma treatment, bonds biomolecules to the Ti surface via covalent bonds.

According to Ajayi et. al. (2012), kaolinite clay are negatively charged aluminosilicate crystalline structures consisting of a three dimensional arrangement of SiO2 and AlO4- tetrahedrally linked to each other by a shared oxygen atom.
This result suggests the partial reduction of Al3+ and Fe2+ from the clay structure, in accordance with the changes in chemical composition as previously discussed in Table 2 and in agreement with the literature [16].
The micrographs of 1M and 5M treated clay indicate the disaggregation and decrease in size of clay structure on acid treatment and in agreement with the previous study [11].

Introduction Nickel supported metal catalysts play an important role in industrial chemistry and have been used extensively in many industrial processes such as hydrogenations, hydrogenolysis, reforming, gas shift conversion, etc., due to its ease of obtainment, high activity and low production.
Various aspects must be considered to develop an inner catalyst structure and create the corresponding metal surface [12].
Using the deposition-precipitation technique, porous structure support, metal concentration in the solution, precipitation time and reduction conditions may be some of the factors that are particularly relevant.
The composition and structure of the unreduced catalyst are of major importance for final catalyst characteristics [13].
