For the JCPDS file number 01-075-2230, and 00-040-1516 corresponds to calcite and chitosan phase, respectively.
While, the morphologies of the eggshells is seen that the ES-PD samples have the porous scattered all over samples and the pattern like stack of lamella foliated and disoriented foliated grains Fig. 3.

Moreover high quality products of UHPFRC enable a long service life even when they are exposed to heavy weather conditions Material Description Ultra-high-performance fiber-reinforced concrete containing fine-grained aggregate up to fraction 1 mm was used for our experiments.

Meanwhile, the joints brazing by crystalline one are easy to form a large number of cracks and brittle phases inside the joints, and it is well known that it has significant detrimental effects on the joint strength and ductility, which limits the applications of the filler metals to some extent [5, 6].
It is well known that boron diffuses extensively out of the joint area into stainless steel base metal during brazing at high temperatures and forms intermetallic boride phases at grain boundaries.

The most parameters on the APS method are current, voltage, spray distance and powder feed rate which are investigated in this study using Taguchi method as an efficient technique for reducing number of experiments for reducing the costs [9-10].

Introduction The occurrence of yttrium and lanthanide oxynitride glasses as grain boundary phases in silicon nitride based ceramics and the desire to understand their nature has resulted in a number of investigations on oxynitride glass formation and properties [1-7].

Besides, the aim was to obtain crystals with a cylindrical shape and flat top surface to minimize the number of low grain boundaries.

Results and discussions A number of facets were observed on as-grown crystal surfaces resulting from the first set of experiments, Fig. 1a.
Grains from the neighboring polycrystalline rim transmit their polytype information into the central monocrystalline area along the c-axis.

The grain size of both materials was 10 µm.

In the machining process, tool materials should have high wear resistance because the silicon grains in the alloy generate abrasive action on the tool and make machining relatively difficult [3].

If corncob residues and more lignocelluloses could be use as feedstock for L-lactic acid fermentation, turning “waste” useful, the grain problem would be alleviated.
All experiments in this report were carried out three times, and the numbers given were the mean values.
