Within this research, biocompatible Ti powder was used, with spherical shape of the grains and size between 15-45µm.
The authors chose the central composition planning, second order, type 2k , where k=3 (k – the number of independent parameters).

Large numbers of reports are available on Ni-P coatings and its heat treatment, the effect of heat treatment of magnesium alloy on the electroless Ni-P coating behavior is yet to be established [8-10].
The eutectic α + β phase is present along the grain boundary.

It can be a direct result of mechanical alloying of the matrix which leads to its work hardening as a result of increased dislocation density, microstrain and also grain size refinement due to the milling process.
It can be explained that at higher load the separation of surface asperities and hence the number of contact asperities increase and consequently the worn surface of material increases.

Consequently, to prepare hollow spheres cocci is a good candidate as biotemplates for encapsulation which offers some distinct advantages: firstly, since the abundant functional groups on the cell walls are inherited from the bacteria which are able to bind metal cations or polar molecules through coordination or electrostatic interactions, no surface modification or activation steps are required, which reduces the number of processing steps and saves time.
In order to remove the organic template completely but to constrain the grain growth simultaneously, the calcination temperature is fixed at 700ºC.

There are a number of small raised particles on the surface of paint film on chemical conversion coatings, the surface is not as smooth as electrochemical method (see Fig.3(c) and (d)).
Add complexing agent DNS into electrochemical solution to slim the coating grains.

LVL is a structural material laminated with multiple thick veneers parallel the grain, and exploits a broad space for its development in the area of structural materials for its good mechanical properties.
The layer numbers of LVL were 12-ply for the birch veneers of 2.6 mm thickness, 11-ply for the birch veneers of 3.0 mm thickness, 9-ply for the birch veneers of 3.4 mm thickness and 11-ply for the poplar veneers of 3.0 mm thickness The test specimens with dimension of 575×90×25 mm were tested under the vertical load, and the test specimens with dimension of 575×25×25 mm were also tested under the parallel load.

Basically, metal oxide semiconductor-based gas sensor material (SMO) must have a grain structure on nanometer scale that has a high surface area to volume ratio [8].
Thus, it will affect the number of electrons released from the O2- or O-ions back to the sensitive surfaces of the SnO2-MWCNT composite.

In addition, any samples with defects, such as high angle boundaries (HAB), low angle boundaries (LAB), sliver, freckles and multi-grains were also considered defective and not used in this study.
This was accomplished by analyzing a number of low-magnification optical images for each alloy.

Both in scientific studies and in practice, the number of powder material properties that influence constant and strict reproducibility of characteristics in the manufacture of consolidated products using the methods of selective melting using electronic and laser radiation is constantly expanding.
The dispersion (grain size) for powder materials PR20H13 and PR12H18N9T were determined using a Occhio500nano image analyzer manufactured by Occhio SA (Belgium) using the static image analysis technique in accordance with ISO 13322-1:2014 as shown in Fig. 1.

Introduction Urbanization is not just the increasing of the urban population and the number of the cities, including cities further socialization, modernization and intensification, which is a complex spatial morphology and socio-economic development process[1-3] .
