Various materials have been developed in recent years for the coagulation and flocculation purposes.
Among them are inorganic-based coagulants, organic-based flocculants as well as hybrid materials [4].
Many materials have been developed and successfully used in removing pollutants from wastewater, there is still a need to improve their performance and reduce the cost of production.

In this paper, logistics strength was given a definition that the product of materials’ weight and distance during a period of time.
Weight of materials and the distance between operating units were two factors mainly considered in the logistics analysis.

Studied on the PAC with the same raw materials and different gradations, and compared with the experimental results of AC-13 modified asphalt mixture and SMA-13, the results shows that, Hamburg Wheel Tracking test not only considered the water-high temperature’s comprehensive action on mixture, but also considered the mixture’s performance decay under long-term loading.
Hamburg Wheel Tracking test can evaluate the PAC’s performance more practically, the PAC which materials and graduations reasonably designed have good performance, and its Hamburg Wheel Tracking final deformation is only 3.89mm, it can satisfy the demand from the high temperature and rainy environment.
As well, the test results also comes to the conclusions that under the same materials and the same air voids, the PAC with coarse framework structure own better water stability and water-high temperature stability.
At the premise of the same air voids and the saw material, coarse gradation PAC have better water-high temperature stability, and stronger rutting resistance ability.

Introduction Organic-inorganic hybrid materials have gained much attention because of their potential applications in optics, electronics, and catalysis[1-4].
Polyoxometalate anions have recently been employed as inorganic building blocks for the synthesis of the functional hybrid materials[5-7].
Considerable interest has been shown in recent years to prepare the hybrid material of R6G with inorganic materials.

The measuring conditions were as follows: sample weight: 10 mg; atmosphere: highly pure N2; ventilation rate: 20 mL/min; reference materials: α-Al2O3.
The curing proccess is one of the key technologies of preparing high-performance materials.
Suitable curing process can increase the cross-linked density of the resin system and it can improve the integrated performance of the materials.

Experiments Experimental Materials.
(1) The raw materials are put into the crucible.
(2) After adding the raw materials, we begin to vacuumize.
(3) We turn up the power gradually in the heating process until the raw materials melt totally
(4) The argon gas as protective gas is filled in the whole smelting process to prevent the raw materials from oxidating.

Introduction Formaldehyde (HCHO) is a colorless gas with strong irritative smell, which belongs to one of volatile organic compounds (VOCs) that are widely used in household materials, medical laboratories and a variety of industries [1].
A series of typical QCM formaldehyde gas sensors had been reported by Bin Ding’s group, in which the sensing materials included PEI/TiO2 nanocomposite [6], PEI/PVA nanofibrous membranes [7], PEI/bacterial cellulose (BC) membrane [8].
Experimental Materials and sensor fabrication.
Afterwards, solution of PVP-MWCNTs composite materials was prepared by mixing 10 ml MWCNTs solution (0.3 wt%) with 10 ml PVP solution, and then was sonicated for one hour.
