The effect of surfactent on the structure of the resulting aerogels was investigated.
The porous structure of aerogels was investigated by Brunauer-Emmett- Teller (BET) instrument and scanning electron micrograph (SEM).
In general, supercritically dring is necessary for silica aerogels to keep the highly porous structure from collapse.

Composition, structure and aggregation of resin and asphaltene With a variety of analytical methods, thorough studies on chemical structure and composition of resin and asphaltene have been conducted[3].
Since the basic structure of asphaltene is a plane structure with fused aromatic ring as its core, the force among the molecule structure of aromatic plane is large and hydrogen-bond groups are easily formed around the core.
It is believed that the above object can be achieved by improving the aromaticity of the demulsifier molecular structure.

After the powders had undergone a calcination process, the samples tend to change from a partially amorphous structure to a more crystalline structure.
This shows that the samples have amorphous structure [5] which is consistent with XRD results.
These bands appeared in all samples and could be related to another phase in the apatite structure.

However, Pan and co-workers[6] used quantum-chemistry to study asphalt oxidative aging.
Asphalt molecular structure would change greatly before and after aging.

Synthesis of copper complexes of poly [2-(dimethylamino ethyl methacrylate)-b-poly (oligo (ethylene glycol) monomethylether methacrylate-b-poly [2-(dimethylamino ethyl methacrylate) Qianqian You a,Puyu Zhangb Institute of Fine Chemistry and Engineering, College of Chemistry and Chemical Engineering, Henan University, China P.R., 475004 ayouqian710@yahoo.com.cn, bzhangpuyu@henu.edu.cn Keywords: double hydrophilic; copolymer; complex.
The chain structure and component of such copolymers were characterized by spectroscopic studies (FTIR, 1H NMR).
These variations in the band might be due to the different structures between Cu(II)/polymer/SO4 complex and Cu(II)/polymer/SO4 complex.
These micelles had clear tubular structure in figure 3 (a) and (c).
Cu(II)/polymer/SO4 and Cu(II)/polymer/Cl2 had different crystal structure.

Further addition of sulfur would result in the formation of cyclic sulfide through recombination of polysulfide, increasing the structure rigidity.
The last is zone 3, through which the modulus keeps fairly constant, demonstrating a fully developed crosslinked structure.
Due to the formation of cyclic sulfide at higher sulfur loading, the polymer structure rigidity increases.
