The test data and analysis
Applying this experimental device, we have completed a number of electric galvanizing experiments under typical different parameters.
Table 1: Electric galvanized experiment under different plating parameters Sample number distance between anode plate and cathode plate.
There is great difference of zinc layer microstructure gained from the gravity test of galvanized under different plating parameters (distance between anode plate and cathode plate, solution flow rate, current density and electroplating time, etc.), and the change of zinc grain size and orientation follows with the change of current density, electrolyte solution flow rate and plate spacing.

A large number of studies have focused in particular on oxygen self-diffusion in these oxides.
The number of the incident beam particles reaching the sample was determined with an accuracy of about 1% using a secondary monitor.
Such low the values in oxides are usually observed at low temperatures [5] and associated with diffusion through fast diffusion paths, such as structural vacancies in the oxygen sublattice, grain boundaries, etc.

The wastewater was pumped into the improved UASB reactor after it passed through R1.
The wastewater used as influent to the experimental apparatus was the mixed wastewater produced from the grain distillery.
Methanosarcina barkeri were found growing nearby the surface of the granular sludge, but the number was significantly reduced.

When this precipitation exceeded the number of nuclei, multi-angular orientation building blocks will grow on substrates.
A three-dimensional growth along their axis from the limited number of nuclei will generate star-like flower structures [14].
The changes from yellow-green to orange emission was also attributed to oxygen defects and defects that took place at boundary layers of nanocrystalline grains [20, 21].

The mortar mix has been made using Portland cement (grade OPC 400 D-0) and sand with grain sizes up to 1,25 [mm], in the ratio cement/sand=1/3; the powdery polymer additive (polyoxyethylene) in the amount of 1 [%] of dry mortar mass has been added to the dry mix of cement and sand.

Despite a number of advantages that PLA has, it has one drawback - the high price.
However, now when considering the PLA market, it becomes obvious that its production is carried out by companies that process natural raw materials, which are a source of carbohydrates: corn, sugar cane and beets, grain crops, as well as companies that produce primary raw materials for the food and feed industry.

The total number of grids is 164*81.
The small grids nested therein are encrypted, with a minimum spacing of 20m and a total grid number of 276*120.
The median grain size is approximately 0.007. -0.11mm, the largest particle size is about 0.07mm, and the particle size is relatively uniform.

Today, there are quite a number of methods suitable for the deposition of PbS films, including the ion successive ionic layer adsorbtion and reaction (SILAR) [10,15], vapour deposition (PVD) [8], pulsed laser deposition [16], electrodeposition [17], spray pyrolysis [18].
In literature, there is a large number of publications discussing the problems of doping lead sulphide films with Cd2+.
In article [6], it has found that the doped lead sulfide films synthesized from the plumbing reaction mixture have a dense, crack-free and more compact microstructure than the undoped PbS, with the average grain size increasing with an increase in the concentration of cadmium salt in the reaction bath.

This may lead to excessive solid-state diffusion and
hence possibly to an increased density of faults and defects in the crystal structure, moreover, bulk
order may be broken at the grain boundaries and interfaces.
The surface energy is then difference between the energy of the slab and that of an equal number of atoms in the bulk.
Time dependences of the number of (a) Ni atoms having an icosahedron as a coordination polyhedron in total as well as constituting the largest cluster from interpenetrating icosahedra and (b) number of atoms involving in the construction of the icosahedra with a Ni atom in the centre.
The forming of such a five-layer A'A"KA"A' surface structure results in a third of surface Pd atoms having increased their number of nearest neighbours from 9 (the close packed f.c.c. (111) surface) to 13 (see also Table 2).
The number of Pd atoms in each couple layers A' and A" coincides with the number of Ni atoms in the Kagomé net layer, therefore, the total atomic fraction involving in build up of the five-layer A'A"KA"A' surface structure in the nanoparticle with consideration of some imperfection of icosahedral order in Kagomé net layer can be estimated at ∼ 70 %.

The particles are deposited one after the other, in a number which can be unlimited.
In contrast, a rapid growth increases the number of pores, which decreases hardness.
Up to now, (almost) only conventional powders, which were formerly developed for conventional thermal spray, i.e. plasma and flame spray, were used in cold spray, in a finer grain size at best.
In addition, the continuous growth in the number of citations until stabilization in 2010, concurrently with a decrease of the number of publications, does exhibit the process expansion, including in industry (Fig.16).
The colors are all the warmer because the number of publications is high, after K.A.
