Nanomaterials, if properly engineered, have unique electrical, thermal, mechanical, antimicrobial and chemical properties that are highly desirable for applications in electronics, energy, biotechnology, medical and environmental sectors.
TiO2, ZnO, nC60 and carbon nanotubes have shown to have strong antibacterial properties [2-4].
The antimicrobial factors such as pH values of ZnO suspension and initial concentration of bacteria strain do not quite understand.
Antimicrobial factor I - bacterial species In order to apply ZnO particles as disinfection using in wastewater treatment plant, the antimicrobial factors affecting antimicrobial activities of ZnO particles were analyzed.
This work tested the antimicrobial factors of bacteria species, pH values of ZnO suspension and the initial concentration of bacteria.

The morphology of the building and its exposure are also important factors.
Therefore, to understand the mechanisms of the formation of plate alteration (spalling), it is necessary to measure the mechanical properties and deformations of the tuffeau under various stresses (mechanical and/or water).
In this article, we delve into the implementation of DIC on tuffeau samples, we explain the effects of various factors that could affect the process starting with the image properties such as contrast and grayscale level, texture lighting conditions, and image resolution.
We should mention that in this article our aim is not to discuss the theory of the DIC but to investigate the external factors that affect this technique.
Many factors could explain the existence of this high-strain zone, our most probable hypothesis involves the presence of microcracks, with also the influence of bedding orientation on its mechanical response.

Hardness is influenced by factors like Al2O3 content, porosity, grain size and micro crack.
When the ZrO2 content is too much, or the reunion appears, then cracks connect, and mechanical properties of products will decrease.
When the content is below 5.4wt%, the mechanical properties of composite ceramics will increase with the ZrO2 content improving.
When the ZrO2 content is above 5.4wt%, mechanical properties of ceramics will decline

The cyclic temperature and the external load are the key factors which influence the strength of the welded joint specimens, while the cyclic period has a minor effect in thermal cycling conditions.
As illustrate in Fig. 2, the thermal cycling process cause decrease of the tensile properties in all the four test groups.
It can be concluded that the cyclic temperature and the external load are the most important factors influencing the strength of the joint specimens in thermal cycling conditions.
Moreover, all the welded joint specimens fracture at its heat affected zone (HAZ) during the tensile tests.
The following conclusions have been derived: 1) The tensile strength of the 5A06 welded joint decrease under combined mechanical and thermal cycling conditions. 2) The cyclic temperature and the external load are the key factors influencing the strength of the welded joint specimens in thermal cycling conditions, while the cyclic period has a minor influence on the strength. 3) The micro-voids nucleation and growth around the particles at HAZ is the micro-mechanism cause the strength deterioration under thermal cycling conditions.

The surface micro-temperature of sliding, rough bodies is an important factor affecting contact properties, such as chemical reactions of automatic injectors for medicine and chemical processes and surface failure of micro- and macro-devices.
The affecting parameters include pressure, roughness, sliding speed, Peclet number, and thermal conductivity of rough surfaces.
Sliding speed and thermal conductivity played the most important roles in affecting the maximum micro-temperature rise.
During the high speed transient process, the micro-temperature of peak contact spots has a different distribution, and affects the adhesion and tribology properties of materials under different operating parameters.
