Application of Different Conductive Substrate Materials for Heat Transfer Enhancement in Cooling of Electronic Components Thiago Antonini Alves a,*, Murilo A.
The possible causes of the failures are the diffusion of the semiconductor material, the chemical reactions, the movement of the glued materials, and the thermal tensions [3].
Heater average work temperature for different substrate materials [°C].
The search for materials with suitable thermal and electrical properties is important for the thermal control of the electronic components.

Finally, the materials themselves are much less expensive than silicon and because the sheets are so thin, they require only minuscule amounts of the materials to further bring down overall costs.
An additional advantage of these materials 2D is their long-term stability , even in open air; other solar-cell materials must be protected under heavy and expensive layers of glass.
Grossman explained that these types of materials are essentially stable in air, under ultraviolet light, and in moisture.
The research on graphene is only the tip of the iceberg in terms of utilizing 2-D materials for clean energy.

The traditional antenna is made up of metal or solid dielectric material, seawater is a new type of dielectric material for antenna.
With the development of science and technology, the antenna evolved from wire antenna to surface antenna, and to antenna with various complex functions.
Recently, a new kind of dielectric material is used as the antenna.
Compared with the traditional metal and dielectric antenna, its electrically conductive material is totally different.

Finite element model Pavement mechanical material parameters and vibration frequency is shown in Table 1, vibration frequency adopts the common default value, and the dynamic parameters adopts the Eq.1, the values of α and β is taken in Table 2, take the surface layer as pavement materials, use three different damping values, take base, subbase and earth base as damping material.
Fig.3 Damping Ratio(0.02) Fig.4 Damping Ratio(0.05) Fig.5 Damping Ratio(0.1) At the same time lateral comparison different than the same speed damping the way of shear stress value for change as shown in table that: (1) no matter how many road speed of shear stress value table with the increase of total damping ratio decreased; (2) but the extent of the lower as the speed change, in the face of a layer damping materials than increasing from 0.02 to 0.1, from high to low speed of the shear stress by 42.3% respectively 34.6% and 28.1%, that is, the higher the speed, damping materials than reduce road of the more obvious effect of shear stress table.
The Table 3 shows that in the dynamic loading, pavement materials damping ratio maximum shear stress influence occupational form the most significant, and the second is the lower modulus on driving speed than the surface thickness and the thickness.

Applying ion chromatography to analyze the decomposition products, it is proved that nano-titanium dioxide can decompose NOx, HC, CO and other harmful gases into nitrate and carbonate.Then, an excellent concrete protection materials- anticorrosive of silane solvent is selected as dispersion solvent, and a certain amount of titanium dioxide is dispersed evenly in the solvent to make the coating material with photocatalytic performance, the brushing method and decomposition effect of the coating material are discussed.
Compared with other photocatalytic materials ZnO, CdS, WO3, Fe2O3, TiO2 owns good chemical stability, reactivity and other characteristics [7].
