Composites structure.
Their action is extracted from the structure of the zeolite mainly silicon.
By using high concentrations of hydroxides may be a recrystalization of the structure to form a new material of gismondine structure, while accompanied by a collapse of the pore structure, and an amorphous phase creation [12,13].
Clinoptilolite type of zeolite retain their structure in a wide pH range, from 1.0 to 11.5.

SEM was used to capture the characteristic network structure in hydrogels [20].
During swelling, the hydrogel further disperses into the swelling medium, resulting to loss of hydrogel material and instability of the hydrogel structure.

The presence of well-dispersed Cu-Ac particles implies their potential role as a supporting structure within the composite.
This can be attributed to the inherent properties of Cu-Ac, which has a graphite-like structure.

Like this, there is a result in teaching. 1.1.2 Principle of structure: In the studying of knowledge, the teaching material should accord with students' study psychology.
Find principle and concept from the changes of the things, this's a main factor which forms study[9] .At the same time, he always emphasizes the importance of the “ structure “.
Pay attention to specific chemistry to practice, let students have greater achievements, help right teaching to promote.
(b) Examine mark as parameter together test, with life scientific and technological study achievement naturally with primary school analyze, the teaching of teaching material, in order to change one by oneself, the primary school test with learning motivation examining marks after the scale with life scientific and technological study achievement naturally for in accordance with changing one, then carry on the parameter analysis altogether of the single factor. 3.4.2 Interview of half a structural formula Make use of and talk the materials through interview of opinion after the study of the digitization teaching material, in order to expect deep one understanding student to digitization idea and suggestion of teaching method of teaching material, and then probe into whole state and its impact on student that course carries on. 5 Discover and the conclusion As to nature and scientific and technological field course of life, include fields such as physics, chemistry, living beings, geoscience

The structure of the raw and degraded chitosans were assessed through Fourier transform infrared spectroscopy (FTIR) and X-ray powder diffraction (XRD).
The FTIR and XRD results showed that the ionic liquid degradation had no obvious effect on the molecular structure of chitosan.
[Gly]+ can easily enter the network structure of chitosan and make the inter- and intra-molecular hydrogen bonds disrupt.
The peaks assigned to the saccharide structure were at 1156 cm-1 (asymmetric stretching of the C-O-C bridge), 1080 cm-1 (skeletal vibration involving C-O stretching), and 897 cm-1 (β-(1-4)-glycosidic bonds).

Pristine CNTs can improve the thermal stability of polymer composites due to the high thermal stability of CNTs, their network structure and free radical scavenging capabilities.
In addition, CNTs contain disordered structures such as dangling bonds, sp3 carbon and oxygen containing functional groups, which can alter the thermal stability of the CNT/polymer nanocomposites as well.
Experimental The multi-wall carbon nanotubes (MWNTs, Chengdu Organic chemistry Co., China) have an average length of 10-20 mm, a diameter around 8 nm and a purity >95%.
The peak at 3440, 1740, 1630, and 1260 cm-1 correspond to –OH, C=O, C-C in graphitic structure, and C-OH, respectively.
Conclusion CNT/polymer nanocomposites have improved thermal stabilities compared to pristine polymers due to intrinsically good thermal stability of CNTs, their network structure and free radical trapping capabilities.
