However, the high water content and biological gel structure properties of sludge lead to difficulty in dewatering.
Traditionally, the excess sludge is conditioned to improve its dewatering properties, and then dewatered by mechanical force.
The properties of the sludge samples as the following: SRF (1.18 ± 0.10) ×1012 m.kg-1; water content (98±0.50) %; pH 6.9 ± 0.02. 2.2 Coal fly ash modification The coal fly ash used in this study was obtained from Chaohu Power Station in Anhui, China.
Effect of EPS on the SRF of sludge EPS concentration is widely studied and is thought to be one of the most important factors affecting sludge dewaterability [10].

Apart from the risk factors mentioned above, the use of the implantation system may cause infections around the implant [9].
Materials used for analyses and their properties are shown in Table 1.
The force affecting the head of the implant was estimated from 2000 N to 4000 N.

Introduction At present, ceramic-metal composite has been widely used in fields like electronic industry, space, atomic energy, high-energy physics, energy transportation, machinery, chemical industry, textile industry and so on.0 Al2O3 ceramic has lots of great properties such as high strength, high hardness, high temperature resistance, corrosion resistance, wear resistance and good insulation.
However the residual stress generated in welding process directly affects the service life of the structure.
Fig. 2 shows the mechanical model of uniform strength beam which was used in the test.According to the formula (1) Any point of stress can be calculated with certain F, b and h.

Carbon nanotubes also had special properties in electrical, mechanical [2] and can be applied in such as nano-electronic equipment [3], composites reinforcement [4], hydrogen storage material [5], electron probe [6], etc.
So catalyst is the important influence factors in preparation of carbon nanotubes.
It can be concluded that the V-type pyrolysis flame method is effective for synthesis of carbon nanotubes. 3.3 Analysis of main affecting factors Temperature was the key parameter in the process of synthesis carbon nanotubes.

Introduction Phenol is considered as priority pollutants since they are harmful to organisms at low concentrations due to their toxicity and carcinogenicity properties.
Phenol is considered as priority pollutants since they are harmful to organisms at low concentrations [3, 4] due to their toxicity and carcinogenicity properties.

The properties of adsorption force were reflected directly by thermodynamic parameters adsorption enthalpy.
And the adsorption enthalpy was the result of these factors, the value of ΔH depended on the competition results of total exothermic effect and total endothermic effect.

Modulation of the metallic oxide properties through of soft chemistry techniques for several applications Altamirano-Juárez, D.
Typically insulating materials in the micro scale became conductive materials due to the domain of the quantum mechanics in their properties.
However, the evaluation of electric and electronic properties is even more important, because they are associated strongly to the morphological and structural changes.

HLW not only has high radioactivity, longer half-life, but also produce a lot of decay heat, these heat is main influence factors to HLW repository, especially for stability and safety of engineering barrier.
In general, decay heat will cause temperature increasing up to about 100˚C, which probably effect structure and properties of buffer material, so thermal conduction of the buffer, namely compacted bentonite blocks, is very important.
In order to discussing thermal properties change pattern of compacted bentonite blocks in situ of HLW disposal repository, advancing domestic HLW disposal level, thermal conduction equipments of compacted bentonite blocks are designed, it is designed according to the conceptual model of HLW geological disposal repository, and using the equipments, the thermal conduction performance of compacted Na-bentonite from inner mongolia GMZ has studied.
As the buffer material, in order to play its role effectively of slowing down radionuclide migration, accelerating the decay heat conduction, homogenizing the pressure from host rock, closing the fracture of host rock, mitigating the mechanical damage and so on, bentonite must be compacted into a certain density blocks.
However, multilayers heat insulation is used, internal temperature change of the system is affected by external temperature after a long time.

TAUC plot of Co: ZnO nano particles. 3.4 Photocatalytic properties of the Co: ZnO NPs.
According to the literature, several possible factors affect the photocatalytic activity of TM doped oxide materials: (i) particle sizes and morphologies, (ii) surface properties, and (iii) dopant content.
In our case, the dependence of the photocatalytic activity could not explain by factors (i) and (ii) because of the similar particle and surface properties of the samples.
Thus, the dopant content of the electronic structure of the Co:ZnO NPs is reasonably the dominant factor affecting the photocatalytic activity.

The long history of using RSW for steel can be attributed to proven robustness and reliability, cost effectiveness and flexibility in production: supported by the physical properties of steel being ideally matched to the process.
However, for aluminium the physical properties, such as high electrical and thermal conductivity, high thermal expansion, and tenacious surface oxide are all less well suited to the RSW process, as eloquently illustrated by Browne et al [7].
As a result of the challenges presented by the properties of aluminium, there have been no significant high-volume production vehicles that have utilized RSW as a primary structural joining technology for aluminium construction; though there are some notable low volume and sub assembly examples of the technology [2,8,9].
This doming behaviour affects energy dissipation during the test, and the changing geometry alters the loading conditions on the nugget.
These factors may account for some further displacement, but not major changes from the trends discussed.
