Alkali-Metal Thermal-to-Electric Converter (AMTEC) is efficient energy converter which can be considered for a number of potential energy applications requiring light weight, cost effective, long life, and high power systems.
The design variables of BASE tube such as diameter, length, grain size, and porosity affect for the AMTEC performance.

Crystalline phase and grain morphology of samples were examined by using X-ray diffractometer (D/MAX-RA) and scanning electronic microscope (S-2700) equipped with an Energy Dispersive Spectrometer (INCA-350), respectively.
Infrared spectroscopy studies were performed with infrared spectrometer (AVATAR 360, Nicolet) in the wave number range of 4000-400 cm-1.

As the fact [3] of low gas production and recycling difficulties, a number of small distilleries are in a common situation that their wastewater is directly discharged not treated or not reached standard.

Based on the conditions, superfine cement which is chosen from a number of different plugging agents is generally regarded as preferred material in deep water plugging.
The median grain diameter of SHD is 10.4μm and SCC is 13.7 μm.

It is a part of polysaccharides, chitosan, and chitin structures derived from the shells such as exoskeletons of crustaceans (shrimp, lobsters, crabs) and other arthropods, fungi, animal bones, bone marrow, grains (corn, wheat, nuts, and tofu), and green vegetables such as spinach, parsley [7].

While commercialization of 4H -SiC is aggressively pursued by leading suppliers of SiC substrates, structural defects such as micropipes, low angle grain boundaries, stacking faults, threading edge dislocations, basal plane dislocations and threading screw dislocations limit the device yield and performance.
The top three drivers are the graphite hotzone, number of wafers per boule and boule run yield.

Both the number and the size of defects decrease when the step-size reduces.
The improvement of surface hardness can be attributed to the combination of grain refinement, work hardening [16] and microstructure change [18].

The ground floor is used to deposit agricultural implements, breed fowls and livestock, storage fertilizer or be used as toilet; the second floor is used as living room, bedrooms, kitchen, and people live in this floor; the third floor is used as the place to storage grains.

The aim of current research is optimization of SLM process parameters such as laser power, scanning speed [3], or powder grain size [4].
Based on the above assumptions and the relatively low number of the SLM specimens, the AE measurements was carried only at several stress levels.
