PDMS is a kind of silicone materials, while the MEA (Nafion®) is fluoride, so 3M® 9119 adhesive tape is used due to its applicable property: one side of the double-side-gelatinized tape is capable of adhering with silicone materials, while the other side is capable of adhering with fluoride materials.
Furthermore, the side of adhering with fluoride materials is able to adhere with metal materials, which has simplified the demand of bonding materials.
In order to simplify the description below, the side of adhering with fluoride materials of the adhesive tape is defined as Side A, and the other side is defined as Side B.

Pb1-xMnxTe crystals
take part as low-dimensional thermoelectric materials in two-dimensioned (2D) quantum well
system [6], in investigations of the effect of negative magnetoresistance and long-term nonequilibrium
process [7], or as materials for the analysis of the nature of phonon dispersion relation
anomalies of IV-VI compounds in the high symmetry phase [8].
The aim of our work was to investigate the structural properties of Pb1-xMnxTe alloys as a necessary component for the better understanding these promising materials. 2.

Compared with traditional fossil fuels, cellulose materials could be regarded as the abundant cheaper renewable resources.
For our country, the yearly available cellulose materials could be counted to over two billion tons.
Wang Weidong et al (2005) adopted the soil and straw stack straw as raw materials, a restrictive culture technique was used to build a set of final screening lignocellulosic composite strains WSC-6.
Table 1-1 showed the corresponding cellulose materials degradation microorganism.
