Introduction Polyethersulfone (PES) ultrafiltration (UF) membrane has been extensively applied to waste water treatment, substance separation, solute concentration, and so on because PES possesses high mechanical property and heat distortion temperature, good heat-aging resistance, environmental endurance as well as easy processing, but its hydrophobicity controlled by PES structure leads to low membrane flux and poor anti-fouling performance [1].

The Wilsonn Code tennis rackets are using the nano-sized SiO2 to fill the holes in the carbon fiber composite material, so that the material structure can be very even and stronger and more compact.
Application of nano-materials in the sports clothing The nano waterproof cloth developed by the Physics & Chemistry Institute of Swiss University of Zurich attracted visitors’ attention in 2010 Shanghai Expo.

The main aquifer is carbonate rocks strong aquifer of the Qixia-Maokou group; it is pure limestone flat fold hydrogeological structure, karst development.
Water chemistry type is HCO3- Ca, the water quality reach class II water standards, it is quality groundwater sources.

The capacity is dependent on the characteristics of rices, e.g. physical structure, moisture content, seed size, degree of uniformity and turgidity, etc.

Especially, artificial GPxs based on small molecules scaffolds have attracted more attentions as the accurately catalytic elements of GPx with designable structure can be anchored to small molecule artificial GPxs[6-8].

The phase-separation process The physical-chemistry method Firstly, add some inhibitors (such as chloroform and carbon tetrachloride, etc) in acidic reactor to restrain the growth of methanogens.
By the precise design of internal structure, we can collocate reasonably for acidification and methanogenesis in one reactor, implementing the two step process, improving the complementary coordination, and eliminating the restriction between equipment investment and land occupation.

Coke properties mainly include internal structure, chemical composition, size and reactivity and other aspects[5].
