One of the powerful promising approaches is using the molecular imprinted technique (MIT) as the recognition mimics preparation of polymeric materials, which have the ability to specific binding the sites by the template molecular [14, 15].
For prepared the polymer membranes, a conducting polymer was firstly to choose; among various conducting polymers, polypyrrole (PPy) is one of the most extensively used conducting polymers in construct of sensors, because it can be generated stable film in a neutral solution,, and easy deposited on a matrices materials [20, 21].

Abstract.
Cr based alloys and high-Cr ferritic steels seem to be the most promising metallic interconnect materials.
For these reasons, the interconnect is a key element for the functioning and long-term reliability of SOFC.
Materials and Experimental Procedure The chemical compositions of the studied alloys: as developed Fe80Cr20 alloys with nominal Cr content of 20 wt% were prepared by mechanical alloying with different milling time 40, 60, and 80 h, and continued with hot press.

Initial development of the technology dated back approximately 30 years ago using polymer as raw material.
The potential of SLS/SLM in developing metal parts directly is high due to utilization of high powered laser source to heat and melt the raw material.
However, the main bottleneck is accuracy and appropriate material properties that give the best end product in terms of mechanical properties that comparable to bulk material.
Critical factors in AM since from the beginning are material capability, accuracy and surface finish.
Understanding of the consolidation process is a key in improving the part fabricated via SLS/SLM.

With the development of the advanced tool materials, hard turning is largely adopted in machining difficult-to-cut materials [5-6].
Titanium can heighten the strength of the material.
Those keys make T250 very difficult to cut.
The worn area of CBN050C grows larger than CBN100, because titanium in the coat reacts with the workpiece material chemically.

Analogously, despite the progress made by the
current deposition technique, more and more accurate research studies are needed to provide thin coatings with
the most suitable characteristics depending on each base material and application.
