Intrinsic kinetic rate of catalytic reaction depends on catalyst, i.e., the composition, supporters, structure of catalyst and catalytic reaction mechanism.
The perovskitetype metal oxide samples with a porous structure exhibited a much faster carbon dioxide sorption rate than those with a dense structure.

As can be seen from the graph, adding phosphorus flame retardant agent had some effect on moisture quantity of polyurethane microporous membrane, but the impact is not big, the reason maybe flame retardant agents uniformity dissolved in pu solution, the process of forming porous did not change the pore structure and size in the later.
From the graph we can see, Polyurethane microporous membrane was three-dimensional network structure which formed by the cell shape relization the structure. when phosphorus flame retardant agent was 8% we can see the microporous size of polyurethane microporous membrane were between 3~6 μm.

It was believed that the original structure was destroyed due to underlying disturbance, in addition to further propagation of the microorganism.
This may be caused by changes in biological structures within system and their activities intensity due to change of pH value and influenced dissolved state of the phosphorus.
Effect of pH on nitrogen release depends on change in biological structures within the system and their activity intensity.

Aluminum as a soft metal of face-centered cubic structure has more slip systems, so it is easy to cause large plastic deformation under stress; while the rigid Al2O3 and Si reinforced particles were non-deformation.
Since deformed structure can be swallowed by recrystallization nucleation and growth, hence the work-hardening was further reduced at this annealing temperature, and meanwhile there emerged more small size equiaxed grains as a result of the growth of fine grains.
After heat treatment of 500 ° C for 1h, the hardness of Al-wt.5%Si-Al2O3 composites was 65.1MPa, closing to the original composites which was 65.51MPa, meanwhile the size of recrystallized grains was also consistent with the original sample and the internal work-hardening structure have completely eliminated.

Its unique structure leads to excellent properties in some respects such as mechanics and electricity.
In order to form a cantilever beam structure, one side of the sample was fastened on the workbench, the experimental system is shown in figure 3.
The test piece was fixed on the worktable, forming the structure of the cantilever beam, and the length of the fixed piece part was still set to 15mm.At the beginning of the test, the composite cantilever beam was set in a state of free release with an initial displacement.

As electroplating technology, both are belong to the ion adsorption behavior under current effect.The difference is, purpose of electroplating is forming coating on the material surface to protect or decorative raw materials, but the purpose of electroforming is obtaining manufacture parts which is hard to made by machining method, the final deposition of metal can form an independent structure.
The basic process includes steam plating, using the metal layers below the photoresist as electrode for electroforming, then filling metal into the void of the three-dimensional structure of photoresist，at last forming a stable concave-convex metal that convex complementary to photoresist pattern.

Schematic explaining the composite structure of phosphorylated pullulan and calcium phosphate with calcium ions.

The poor formability of magnesium at room temperature is inherently related to its crystal anisotropy and hexagonal close packed structure, which limit the number of active slip systems and primarily involve only the basal planes [1].
It is anticipated that exploring the synergy of melt chemistry and physical treatments achieved through Liquid Metal Engineering allows the creation of the optimum conditions for nucleation and growth during solidification, positively affecting quality of castings [7].
Thus, a replacement of dendritic structure with globular ones is generally accompanied by a reduction in porosity.
At the same time, the porosity (and other solidification defects) will exert a contribution when comparing globular morphology with wrought grain structure, known to be fully dense.

MOFs have recently gained increasing interest owing to their exceptionally high surface areas and structural and functional tunabilities [12], because the wide variety of metals, organic linkers, and synthesis methodologies makes possible the wide array of designs of materials with different structures and properties [13].
The aluminum fumarate MOF was synthesized and supplied by the Chemistry Department of CYCU.
This could be due to the rigid structure of A520 creating possible molecular sieving property for the membrane [17], as demonstrated by the increase in permeation (Fig. 1).
This could be due to the rigid structure of aluminum fumarate creating ultramicropores [18] and improving free volume property for molecular sieving [19].

At this stage of our work, two hypotheses can be envisaged to explain the changes in the 2-pentyl-2nonenal E/Z ratio as a function of the catalyst composition: (1) The aldol dehydration mechanism (and as a consequence the E/Z ratio of the resulting α,βunsaturated aldehyde) is determined by the acid-base properties of the catalyst or by its surface structure
(2) Neither the acid-base character of the catalyst, nor its surface structure have an influence on the aldol dehydration step, but the α,β-unsaturated aldehyde formed in the reactor through aldol dehydration is isomerised in a secondary reaction; the final E/Z 2-pentyl-2-nonenal ratio depending on the nitrogen content of the catalyst.
This apparent discrepancy could be attributed to - either the importance of the catalyst surface structure on the specific interactions of the aldol intermediate with the catalyst surface and hence, on the aldol dehydration step, 4 10 14 14 13 9 20 2 9 16 14 14 11 18 0 5 10 15 20 25 H-ZSM-5 SiO2-Al2O3 AlPO4 AlPON-14%N Al0.5Ga0.5PO4 AlGaPON 12.5%N KF(40 wt. %) /Al2O3 E/Z jasminaldehyde 2-pentyl-2-nonenal - either to an important secondary isomerisation of the α,β-unsaturated aldehyde after the aldol dehydration step.
