Recently, with the increase of scale inhibitor studies, people paid more attention to the structure of PASP molecular and introducing effective functional groups.
This showed that the amine- intermediary products have two adjacent carboxyl coupling; and the synthetic products did meet the structure of PSI ring unit.
As shown in Fig.9 a and b, calcium carbonate particles formed in the absence of scale inhibitors exhibit compact structure and neat hexagon.

The EGFET is chosen due to its advantages such as simplicity of passivation and packaging insensitivity to light and inexpensive structure [1, 2].
From Fig. 2 (b) it can be seen that the Au island begin to form and grow after annealed process for 15 min while when the Au thin films was annealed for 30 min, the adjacent grains start merging into each other and form chain-like Au island structures while the fraction of uncovered surface gradually increase as shown in Fig. 2 (c).
As reported by Zhao et.al, as duration of annealing time exceeds over 10 min to 30 min, the evaporation might be dominant, which possibly deteriorates the perfection of crystal structure [15].

Using the precipitation of coherent intermetallic c0 -phase with the Ni3(Al,Ti) basic composition and the L12 crystal structure, the precipitation strengthening is achieved [6].
The base metal chemistry and microstructure were evaluated using a Jeol JSM IT300, scanning electron microscope, attached with an Oxford Energy dispersive X-ray analysis (EDS) having Aztec analysis software.
This plays a vital role in understanding the changes undergone in the microstructure and its respective chemistry.
Meanwhile, Op4 shows a clear change in the micro-structure with a different grain-boundary appearance, especially near the surface.
At Op3, Cr had a noticeable 5% decrease, which is consistent with the micro-structure and hardness readings indicating a relatively higher thermal exposure.

It is well established that the electrical parameters play an important role in the formation of phases and structure of ceramic films made by MAO technique.
There are porous and some island-like structures distributing irregularly over the surface of composite coating.
The island-like structure was produced by molten oxides flowed out of the discharge channel and rapidly solidified.

The results show that the products have an X zeolite crystal structure and present super paramagnetic properties.
This can be explained as the more orderly structure after calcining.
Magnetic zeolite composites have an X zeolite crystal structure and superparamagnetic properties.

Its breathable characteristic that makes it ideal for gas storage becomes a disadvantage in terms of structure elucidation.
The high crystallinity, exhibiting a rigid character with an accessible permanent porosity, was good enough for structure elucidation.
Aluminum fumarate (A520) was supplied by the Chemistry department of Chung Yuan Christian University (CYCU).
This could be due to the rigid structure of A520 creating possible molecular sieving property for the membrane.

Investigation of the effect of hierarchical structures on physical properties and the
nature of interaction of various internal fields in inhomogeneous materials is inseparably linked with
the development of methods of synthesis of new smart and intelligent structures.
Hierarchy of dendritic structures.
Microheterogeneous structures can be implemented in solids in the presence of long-range order in the arrangement of atoms (crystalline structure), short-range order (amorphous substances), and also in the structural state of intergrain boundaries (for example, in layered structures or nanocrystals).
Electrophysical properties of such structures, mostly static, are widely discussed in literature, along with their relation to composition, parameters of structure and processing features [5-9].

The heat flow direction governed the orientation of the air bubbles, and set the inner structure of ice.
Ice formation has been addressed less and affects the internal ice structure at the millimeter-scale [5,6], but re-crystallization processes in case of ice damage under load influences the ice structure at the centimeter scale [7].
On the other hand, KS was used for a side view observation and much deeper focal zone provided semi-3D information about the orientation of bubbles in ice (Fig. 2b-2d). 100 µm (a) P-H surface 100 µm (b) S-H structure 100 µm (c) P-H structure 100 µm (d) P-C structure 1 2 (NI) 3 (II) 4 (IS) Fig. 2.
That could be explained by the 3D structure.
