Research result indicated that the cooperative effect between swell and precursor is main factor for the nanoparticle loaded in Nafion, and moreover, polarity of solvent and water content in Nafion also affects the load largely. To improve away the surface concentration of CdS nanocrystal on two side of membrane for general preparation, thioacetamide was first used as a precursor instead of inorganic sulfur source(H2S and Na2S) in synthesis of CdS nanocrystal. The assembly mechanism for several sulfur source had been studied, and CdS/Nafion with the character of homogeneous disperse had been prepared, which is fit for mass transmission in photocatalitic reaction. Following the investigation of several crystallizing way, simple and reliable hydrothermal-crystallizing was found. According to this way, maximal TiO2 load in Nafion achieved 43%. Activity of TiO2/Nafion or CdS/Nafion as a photocatalyst was explored initially for disintegrating liquid contamination. Maximal decompose rate achieved 86% under condition of this research.

Analogies are proposed between the East African Rift System and the Baikal Rift System with the Tharsis region of Mars, including the giant rift, Valles Marineris, Both regions are the result of mantle plume tectono-thermal activity that caused crustal uplift, volcanism and rifting. On Mars, we suggest that the subsurface ice, or cryosphere was liquefied as a result of igneous activity and or asteroid or cometary impacts, generating convecting cells of hydrothermal fluids.
