Due to high aspect ratio and nanometer scale radius , CNTs have high electron emission efficiency at low voltage, So CNTs have been regarded as one of the most efficient electron emitter materials.
In fact, for different work function and electrical conductivity of materials, when CNTs are synthesized on Si substrate with different material buffer , CNTs maybe show different emission properties.

This concept is important because it can be used as a „ check-list“when designing an algorithm for bone grafting, since treatment requires: - Identifying which factor is missing or inactive, and - Correcting the imbalance, so that all the components of the diamond concept could act together according to this concept Material and Method Surgical experience in a Level 1 Trauma Centre was used as a base for this algorithm.

However, these materials are not good in resistant soda corrosion, even in some enterprises they are not full used[2,3].
But, due to the high Ni content in the High-Ni-iron, the cost of materials has been increased.
In this sense, it is useful since the alloy iron enriches Ni and Cu, and it also means that some matrix materials are consumed.
