Carrier mobility of the graphene thin film is one of the most crucial factors to achieve superior device performance.
Factors that influence the carrier mobility include film crystallinity, layer number, presence of contaminations, and effect of the substrate.
However, factors such as surface phonons [10], roughness [11], and trapped charges [12] restrict the carrier mobility.
The graphene thin-film is expected to possess superior electrical properties.

Results and Discussions Mechanical properties.
Table 3 Mechanical properties of the experimental steel No.
Different annealing process can deserve different retained austenite content and it can also impact retained austenite morphology, distribution and affect ultimately the mechanical properties of TRIP steel.
These factors play a vital role on the mechanical stability of retained austenite and mechanical properties of TRIP steel.
Influence of annealing temperature on microstructures and mechanical properties.

The mainly factors which affect composite material are temperature, humidity, ultraviolet radiation, oxygen, water, salt spray, chemical media, microorganisms.
Polymer matrix composites form, quality, mechanical properties and other indicators will change in synergy humidity and temperature, resulting to reduce the life and safety of composite materials [4~6].
Therefore, the mechanical properties of CF3011/BA9916-II composites showed a downward trend in the marine environment with the growing of aging time.
Combined 2.2 macroscopic mechanical test results, we can see that the aging of the composite material is the accumulation of microscopic damage to mentor their macroscopic mechanical properties decrease.
By inference, the composite moisture are directly related to the mechanical properties and the specific performance the mechanical properties of composite materials have different degrees of decline with the increasing of moisture. 3) In the marine environment, CF3011/BA9916-II composite carbon fiber and resin matrix bonding situation with aging time increases gradually deteriorated.

This paper reports the effect of temperature on the physical, mechanical properties and characteristics of kaolin geopolymer ceramic.
The type of alkali ion, Si/Al ratio and crystal structure themselves are the important factors included [16-18].
Table 2 concludes the mechanical properties of 12M0.24 kaolin geopolymer ceramic at different sintering temperature.
It proved that higher temperature (up to 1200 °C) does help to enhance the mechanical properties.

Specification cutting tools durability made of cutting ceramic in machining process of steel 80MoCrV4016 is very important for economics of small and medium-sized enterprises, because cutting tool durability is factor that significantly affects the budget of these enterprises.
Technical science defines a lot of different factors, that they may be cause of shorter cutting tool lifetime.
For increase cutting tool durability is necessary maximally possible elimination of these factors.
As new materials were developed during a specific era, the properties of the cutting tool improved.
Material for workpieces is from specific material list with guaranteed chemical structure and mechanical properties.

The reason for that is Si3N4 ceramics are characterized by excellent material properties such as high mechanical strength, high temperature resistant and high shock resistant.
One major advantage of the EDM process is that there is no direct contact between the tool electrode and the work piece electrode and thus the process is independent of mechanical material properties of the electrodes.
Gap voltage seems to be the least significant factor affecting MRR.
The most significant factors affecting the TWR are current, servo, open voltage and the interaction between current and servo as shown by the Pareto plot in Figure 3 (b).
Current, servo and the interaction between them were found to be the most significant factors affecting both the MRR and TWR followed by open voltage.

The antibacterial properties were tested against E. coli suspensions.
However, the wide different in mechanical and physical properties between copper and stainless steel prevent the copper application as stainless steel substitute widely.
Therefore, the mechanical and physical properties of copper should be improved by some mechanisms, such as alloying.
In this test, the main factor that affects the inhibition zone diameter is ion diffusion ability to agar medium.
One of the main factors for the alloys to reduce the number of bacteria is the contact surface of metal and alloy to bacteria.

Mechanical properties and Tensile fracture mechanism of Rheocast A356 Al alloy using Cooling Slope Prosenjit Das*1,a, Sudip K.
Near spherical primary phase in the rheocast alloy ensures better strength, elongation properties and structural integrity in the produced billets.
So, grain refining helps to improve the strength, elongation and fracture properties of rheocast billets further. 1.
The literature available on the topic confirms the effect of microstructural characteristics on mechanical properties and fracture behavior of Al-Si-Mg alloys [5].
Dendritic structure is also responsible for microporosity formation as it creates a solid skeleton within the melt during solidification and reduces its fluidity, which in turn is responsible for air pockets (microporosity) in the solidified ingots and effects the mechanical properties detrimentally.

The results demonstrate that the modified fiber with well-distributed of nano-silica has excellent mechanical properties, and crack resistance.
Introduction For fiber reinforced cementitious composites, the interface transfer the fiber-matrix stress, which is one key factor of determining the mechanical properties of composites,toughness and crack-resistance.
Nano-silica has been widely used in cementitious composites, which can promote hydration, shorten setting time, reduce porosity, improve microstructure and mechanical properties [4-15].
To evaluate the factors affecting the interfacial strength properties of plasitic FRM (≤6h after mixture ), single fiber pull-out tests were performed by using a modified special apparatus.
