Incorporation of antimicrobial agents into PU will provide good antibacterial properties of the PU-based materials.
The experiments were carried out according to the methods reported in literature [8]. 2.2.2 Antibacterial adhesion assay Materials solidified in the toflon mould (Φ5.0mm×3mm) were immerged in 1mL bacterial suspension (106 CFU/mL) after sterilization for 24h.
Neverthless, the proliferation of bacteria in PU and blank control groups (without materials) does not inhibit.
In Group B wells, where transferred bacteria were incubated in the absence of the tested materials, measuring the short-term direct contact effect, results do not differ.

Mechanical properties of materials under high pressure.

In this prospect the structural integrity of components exposed to high pressure of gaseous hydrogen as the hydrogen compatibility of the materials used have to be examined.
Moreover, several studies use this kind of model to successfully simulate the propagation of fatigue cracks in different types of materials [6, 12].

Greater competition and strict standard requirements result in the dynamic development of material sciences.
Manufacturers of dental prostheses have developed new materials such as composite materials, powders and hybrids.
Thanks to these developments patients can choose from a wide range of materials and services e.g.
Tribometer presented in Fig. 1 is a universal tester used to evaluate tribological characteristics and selected mechanical properties of biomaterials, including materials for dental prostheses, materials for tools and medical instruments.
However, this research process was meant to quickly verify implant materials and in effect the focus was on the implant.

For instance, silver has been concerned in materials science for decades for its impressive antibacterial capability and low toxicity[11, 12].

This project compounded zirconia materials with aluminum titanate by nano-technology.
However, grain size distribution of composite materials prepared by solid phase is uneven.
Porosity of the materials is large.

The third is the introduction of foreign database of Internet services, including the purchase of five 6000 kinds of journals the full text of the original foreign-language data, including dozens of databases.
This does not mean that all the network information resources needed to survive, but with preservation of part of the value of information resources, in particular, there is no printed version, only the network version of those natural sciences, humanities and social science of electronic literature, electronic journals, the Institute communication journals, such as the preservation of the social is an extremely important issue.
MARC data such as the Museum of the Title and the index of self-built databases, doctoral, post-graduate thesis database, conference papers, abstracts CD-ROM databases, electronic publications, multimedia materials, Internet online resources.
At the same time, the National Science and Technology Center Library also officially established.

Acoustic Emission is widely used in studies of rock fracture instability mechanism and other materials because internal micro rock cracks produced and extended in the process of rock breaking can be monitored in real time and then the position of rock failure can be located [2].
