III-N materials have a direct bandgap spanning from 0.7 eV to 6.2 eV and their tunable optical emissions range varies from infrared to ultraviolet, making them suitable for optoelectronic devices.
III-N materials are commonly investigated in light-emitting optoelectronics [2-5].
Development conditions that did not allow high-quality non-doped GaN were not effectively controlled; The GaN materials produced were primarily n-doped, with electron concentrations ranging from 1018 to 1020cm-3.

In the design of piezoelectric actuator the concept of compliant mechanism combined with piezoelectric materials has been used to magnify either geometric or mechanical advantage.
The polarization of piezoelectric materials is considered to improve actuation since the piezoelectric polarization has influences on the performance of the actuator.

These became an opportunity for the engineer to seek a new acoustic materials or new methods to enhance the noise absorption and attenuation.
Some researchers [1-4] have developed new acoustics material using natural product for the noise absorber materials.
Beranek & Ver [11] use same idea to calculate the acoustic impedance of perforated plate backed with air cavity or porous materials.

Thus, these papers can represent an useful link for passing throughout the full process in terms of changes on the mechanical properties of materials (integrating information available in [19, 20]).
As expected, a large number of standards already exist, dealing with ceramic materials and products.

Introduction Recently, the recycling of materials is advancing, influenced by the need to conserve resources [1].
However, it is very difficult to make a composite of these materials, because the characteristics of the materials are greatly different.
It is possible of layer the green compact of different materials by repeating the wet-shaping process with these characteristics.
Though sintering is relatively easy in the composite material when plural materials are sintered under similar conditions [3], when totally different materials are layered to produce a composite material, the composite material cannot be sinter because the sintering conditions are totally different.
