Porous materials made from biocompatible metals such as stainless steel (316L) and titanium (Ti-6Al-V4) are currently in use as conventional material.
Because of this, porous NiTi alloy is chosen because it exhibits lower apparent elastic modulus close to human bones compared to other metallic materials [1,2].

The micro-bridge comprises a thin layer (0.1-0.3μm) of sensitive materials.
Fig. 1.Mircobolometer structure Microbolometer is based on the measurement of a temperature change due to absorbed IR photons by sensitive materials such as vanadium oxides, a-Si:H, semiconductors, superconductors and so on [4].
Among all the sensitive materials, a-Si:H has high temperature coefficient of resistance (TCR) and high resistivity to gain high responsivity [5], therefore, in recent years, the study aiming at microbolometer based on a-Si:H thin film has attracted a wide spread attention.
Fig. 8.Absorptivity vs. thickness of support layer Conclusion The simulation of the multilayer film system based on a-Si:H shows that, among all the IR absorbing materials, TiN has excellent IR absorption performance.
Compared with TiN, other IR absorbing materials (such as Si3N4, SiO2) are not so good, but can be used to act as the support layer or passivation layer.

Introduction
The flow of non-Newtonian fluids confined in channels with expanding and contracting walls have applications in heat exchangers, engine systems, lubrication systems and many other chemical engineering applications like packing toothpaste, shampoo, food materials and biological flows like lymph fluids through vessels, etc.

The FEM is the most popular based on the number of journal publications.
Wherever this sensibility is low enough the material can be progressively eliminated.
Holes are created by removing material areas centered on the previously selected points. 4.

Introduction
The application of secondary materials form anthropogenic high temperature processes in building material has a long tradition [1].
Some application properties are even improved due to the special properties and reaction behavior of the secondary materials.
Secondary materials like ashes or slags furthermore can be submitted to chemical treatment to generate an activation of the silica structure.
The SMM is known for the capability to produce nano-sized materials [9, 13].

Previous researchers have used different materials as a replacement for cement.
The utilisation of waste materials as supplementary cementitious materials (SCMs) can reduce the harmful impact of using cement on the environment.
Waste materials are the materials produced by some industries or chemical processes that are not required in production and are discarded.

Introduction Electrophoretic deposition (EPD) is a very important and versatile technique for processing colloidal suspensions of particulate materials and has been used in a variety of applications such as fabrication of thin films, multilayered composites, functionally graded materials, hybrid materials, as well as micropatterned colloidal assemblies [1,2].
These advantages have promoted interest to develop water based EPD to process particulate materials and technical ceramics [5-9].
