The development of solid oxide fuel cell with thin film concepts for an electrode supported design based on the yttria-stabilized zirconia has demonstrated favourable results due to its high chemistry stability in oxidization and environment reduction.
It is well established that the morphology and structure of deposited films are strongly linked to: the substrate temperature [12], the solvents used in the solution [13] and the temperature of heat treatment [14].
The crystalline structure and the average crystallite size were investigated by X-ray diffraction (XRD, Bruker D8 Advance diffractometer) using Vantec position and copper cathode with Cu Kα radiation, λ = 0.15418 nm.

Both, surface topography and chemistry determine surface wettability.
Interaction between the drop and the surface is mainly controlled by surface chemistry and topology.
Many studies have been made analysing the structure of the Lotus leaf, showing the importance of the double scale of roughness (micro and nano scale) for achieving superhydrophobicity [6, 7, 8].
Different structures can be achieved, depending on how fast the liquid-liquid demixing process is, i.e, how fast phase inversion is induced.

The effects of aluminum content on zeolite particle morphology and structure were studied.
Powder X-ray diffraction (XRD) results showed that the composite zeolites are of both MCM-41 structure and zeolitic MFI structure.
Moreover, R-4 crystal is almost loose aggregates, showing a completely different morphological structure from that of the intergrowth or twinning.

TEM of the unmodified kaolin (ORK) and SMKS revealed that a layer of ultrafine silica particles were deposited on the kaolinite surface to form a new kind of core–shell structure particles.
They are available in a wide variety of chemistries, both naturally-occurring (mined) and synthesized.

The filler usage in final chemistry and paper preservation help needs a certain degree of comprehension in the area of paper output chemistry.
It was due to the paper composition (chemical structure) or chemical reaction (oxidation).
The fibre structures of magnetics sugarcane bagasse paper were shown in the Fig. 2(a).
The structure is in irregular shape and occur molecule agglomeration (red around shape).

For interesting compound, BaHPO4 have been widely investigated due to their proper crystal structures and utilizations [11-19].
The crystal structure, vibrational study, and non-uniform and porous structure will be also discussed.
These results indicated that the BaHPO4 crystal structure is in orthorhombic system with space group Pn21a (33) (Z=12) and the Ba2P2O7 crystal structure is in hexagonal system with space group P62m(189).
