The data reveal that the phosphorus content for the as-deposited Ni–P coatings range from 11.01 wt.% to 7.76 wt.%, as the corresponding to an increase on pH value of the plating bath from 4.4 to 5.4.
Excessive tensile stress can cause warping in addition to cracking and reduction in fatigue strength, however, compressive stress can be beneficial to durability and anti-wear performance of the Ni–P coatings.

The tests were performed on an universal testing machine with a cross-head speed equal to 10mm/min (0.17mm/s) and the stress-strain relationship was fitted by the following three different work-hardening models (Hollomon, Swift and Ludwik): σHollomon=C1εpln1 (1) σSwift=C2εpl+ε0n2 (2) σLudwik=C3εpln3+σ0 (3) In Eq. (1), Eq. (2) and Eq. (3) C1, C2, C3, n1, n2, n3 ε0, σ0 are constants obtained by data fitting and εpl is the effective plastic strain given by: εpl=23εijplεijpl (4) The experimental stress-strain behaviour for two different compression tests, together with the best fit given by the aforementioned work-hardening models, is plotted in Fig. 3.
It is seen that closure of the central hole is significant (approximately 20% reduction of the average diameter).

Glycerol conversion data on various reactant comparisons can be seen in Table 1.
However, an increase in the mole ratio from 1: 7 to 1: 8 caused decreasing glycerol conversion slightly, this may be due to a significant reduction in the glycerol concentration [9].

Due to its uniqueness such as a low cost material but having great catalytic properties and high electronic carrier, that can enhance the redox reactions during reduction process, makes the NiO is typically used as an anode material.
The data were collected in the 2θ range of 20ᵒ to 80ᵒ with 0.02 ᵒ/sec scanning rate for each step with Cu-Kα (λ = 0.1540558 nm).

There are variety ways of deposition thin films, by using chemical such as co-precipitation, sol-gel, microemulsions, sonochemical synthesis, and UV-initiated photo-reduction while physical such as vapor deposition, sputter deposition, electric arc deposition, ion beam technique, molecular beam epitaxy, and melt mixing.
The XRD analysis were performed by taking data at 2θ angle ranged between 20˚ to 80˚.

Introduction Drying is a thermodynamic process where reduction in the moisture of the solid occurs simultaneously with heating of this material.
In addition, to naturally presenting a concise language, also brings aspects such as the possibility of confirming or rejecting certain assumptions related to systems, reveal contradictions in data obtained and/or hypotheses formulated and predict the behavior of a system under untested conditions in laboratories.

However, the reduction in mechanical strength can be enhanced by treating the tyre aggregate using the water-soaking treatment method.
Therefore, the lack of research data, limited information, and knowledge on the mechanical properties of concrete made with waste rubber tyre aggregate (WRTA) as a partial replacement for BA motivate this research work.

- the height of weld (Hs.w.) seam depends on the power of laser radiation (PLR) while the height of the seam shrinkage distortion (Hs.d.) becomes smaller with the growth in the weld rate from 16.6 mm/sec to 33.3 mm/sec, by means of the reduction of the surface plasma intensity which results in less concentrated electrons in plasma, its narrowing towards the beam [17].
