Such property is related with the adsorption feature at the air/solvent interface, which is ultimately determined by the structures of the surfactants.
Most of traditional surfactants are water soluble with a hydrophilic segment and a hydrophobic segment in the structure [1].

The forming mechanism of the nanoporous structure was studied by a liner sweep voltammetry experiment.
The high specific surface area of NPC can be attributed to the micro/nano scale bi-continuous 3D porous structure formed by dealloying.

In parallel, optical microscopy was used to directly observe the development of crystalline structures during heating.
PET forms well-defined spherulites within minutes at 230 °C, whereas no visible crystalline structures appear for PEF under 180 minutes.

Various particle sizes ranging from nano to micron, are obtained depending on the chemistry used and the processing technique applied during the production.
Most of those structures had a length of 3-4μm (3000-4000nm).
Among them, there were acicular structures accumulated in groups.
At the images the fibriller-semitubular structures were not uniform in terms of shape and distribution.
It can be observed from Fig. 4a. that the fibriller structures were very dominant and they had gathered in some semi-circular groups.

Synthesis and Properties of A Novel Material Chemistrty Unsymmetrical  Material,Diarylethene with Cyano Weiwei Geng, Congbin Fan, Shouzhi Pu* Jiangxi Key Laboratory of Organic Chemistry Jiangxi Science and Technology Normal University Nanchang 330013, P.
The photochromic process of diarylethenes is based on a reversible transformation between the open-ring isomer with a hexatriene structure and the closed ring isomer with a cyclohexadiene structure, according to the Woodward–Hoffmann rule [16].
The open-ring isomer is colorless in most cases, while closed-ring isomer shows some color depending on the molecular structures [17].
The structure of compound 1a was confirmed by 1H NMR spectroscopy. 1H NMR (400 MHz, CDCl3, ppm): δ1.94 (s, 3H, -CH3), 4.07(t, 4H,-OCH2-CH2O-), 7.14(s, 1H, thiophene-H), 7.68 (d, 4H, benzene-H).

Polymerisation and polymer modification are often carried out by means of radiation methods, since irradiation can modify the structure of materials and improve their performance.
This paper reports measurements on various polyesters subjected to gamma irradiation, which differ in the monomer structure.
