Maifanite is a common mineral silicate rock which has the pore development mesh structure.
Benefit from this structure, Maifanite shows better adsorption performance.
The pore structure was improved after modification, which was in favor of removal of pollutant.
The physical adsorption is related to the structure of Maifanite.

By carefully selecting the structure of dyes, especially the metal complex dyes, and studying the properties of the prototype display.
The light fastness of most dyes is not enough, and the majority of the dark cored dyes are of direct dye's structure.
The stability of dyes' structure under voltage driving Fig.3 shows the cyclic volt-ampere curve (-2V to 2V) of Red 04 in ethanol (2.2×10 -3mol/l).
Structure damage of dye during electrophoresis was studied.

This paper reports a new method for the preparation of PVDF-g-PSSA membrane by a solution-grafting technique, and has a study on the membrane conductivity as well as the effect of relative humidity on the conductivity on the base of its structure [9]. 1.
(1) The conductivity was calculated according to (1), where was conductivity, R was resistance of the electrolyte, A and L were the cross-sectional area of the swollen membrane and the thickness of the membrane, respectively. 1.4 Structure characterization.

Quasi-solid-state electrolytes are usually prepared by incorporating a large amount of a liquid electrolyte into organic monomer or polymer host matrix forming a stable gel with a network structure via a physical or chemical method [9].
Moreover, the dry chitosan films are also strong and flexible due to the presence of β-(1 → 4) linkages between the glucosamine residues in its structure [10].

The structures of the products were analyzed by 1H NMR (Fig. 2).
In contrast, the mutual interaction of long reaction time and OLLACOOH chain structure causes more side reactions, resulting in worse yield.

Results and Discussion The crystalline structures of TiO2, Gs/TiO2 and Gs were evaluated by XRD.
The obtained GS/TiO2 photocatalyst exhibits photocatalytic properties enabling visible light–driven for decomposition of agricultural residues with the apparent first–order rate constant k = 0.0102 min–1 Acknowledgements This research was financially supported by the National Research Council of Thailand (NRCT) and the Program in Chemistry, Faculty of Science and Technology, Uttaradit Rajabhat University, Uttaradit, Thailand.

The AA3 instrument was composed of a XY-2 sampler, one high precision pump, one chemistry manifold and a digital colorimeter.
Because of tobacco dust pulp soft and thin, it will not blocking effect on fiber network, on the contrary, it will make fiber network structure have contraction capacity and fiber distance were shortened, this is the main reason for reconstituted tobacco paper-base air permeability decreased.
Tobacco dust ratio less than 30%, result of SEM showed reconstituted tobacco paper-base loose structure, most of the tobacco dust pulp was filling between tobacco stem fiber and fiber, there were few tobacco dust pulp on the reconstituted tobacco paper-base surface.

Numerous void spaces corresponding to the bubbles of different sizes were observed in the structure of the fibres fabricated with the fluids.
The presence of the bubbles in the fibre structure can alter the physical properties of the fibres.
