Besides the desired properties of the obtained sorption material (mechanical strength, porosity, specific surface area, the chemical nature of the surface) technological factors and characteristics of the cleaning solution affect the sorption.
For this reason, the determination of physico-chemical properties of the newsorption material is necessary.
The equilibrium concentration of zinc ion in solution, mg/l A systematic analysis showed (Fig. 1) that an increase in the specific surface area of the sorption material increases its adsorption properties.
Effect of temperature on the adsorption capacity of solutions sorption material The work investigated the effect of pH on the properties of the resulting composite.

On the other hand, few studies [5] have been reported on how the rapid heating affects the cementite dispersion and mechanical properties using low C steels for welded structural use.
However, it has not been clarified as to how these elements affect the cementite precipitation behavior and mechanical properties when rapidly heated.
Figure 4 shows the effect of rapid heating and tempering on the mechanical properties.
Table 2 shows an example of mechanical properties of steel plates manufactured with the HOP.

Introduction Titanium is a well-known biomaterial, successfully used in the biomedical field, for the fabrication of implants due to its low density, stability in biofluids, good mechanical properties and biocompatibility [1-2].
The native oxide layers on Ti are spontaneously rebuilt in biofluids whenever they are damaged due to an aggressive pH or mechanical factors [3, 4].
Having stability and biocompatibility, and taking into account all the coating and surface activation methods, titanium is one of the most attractive implant material [3,4], but building a nano-tube structure could lead either to an improvement of a quite large range of properties as changing of hydrophilic - hydrophobic balance, increasing biocompatibility, changing nano-porosity, stability, etc.
Such properties are important not only in tissue engineering, but also in other domains, as self - cleaning, solar energy conversion, controllable wettability, electrochromic devices etc. [11-12].

For example, physical properties such as density, biomass content, compressive strength, and other relations between them can be potential parameters.
In addition, the use of adequate SCMs can improve some properties, e.g., rheology and mechanical, as verified by Caldas et al. (2020a) and Andreola et al. (2019).
It is important to say that a fair comparison among different bio-concretes must be done carefully, especially when they have diverse bio-based content and, consequently, properties.
Therefore, we conclude that the country’s electricity mix severely affects the bio-concretes carbon footprint and the curves’ adjustment.
If thermal properties of the bio-concretes are available, e.g., thermal conductivity, a thermal efficiency indicator can be used.

Kaviany studied factors affect critical heat flux of Capillary artery evaporators, mainly the capillary-viscous and hydrodynamics-instability, by way modulating wicks and liquid artery.
Theoretical Calculation Three wicks properties prominently affect the thermal behavior in heat pipe: capillary radius R, the wick resistance or the permeability of the wick, and the effective thermal conductivity Keff.
Permeability is depending on the interface properties of wick material and working fluid.
A high equivalent thermal conductivity, high permeability, and a low capillary radius are optimized properties in most heat pipe’s wick design [7].

According to Archard's wear model, normal contact force and sliding distance directly affects the wear.
Characteristic areas on sheared edge profile, variation of punch force and high contact pressures affected areas have also been analysed.
Past research into tribology suggest that wear of the material is not an intrinsic material property, which is affected by many factors (including the application situation).
The characteristic area on the sheared edge profile, punch force versus punch displacement curve, and high contact pressures affected areas have been extracted from FE simulations.
Cutting process parameters, such as the sheet metal and tooling materials, sheet metal thickness and clearance affect the mentioned zones [8].

It can also cover the other structural effects for example the temperature influence which can significantly affect to the later structural behavior.
For the stress analysis of such non-homogenous structures where the basic concrete properties and the structural scheme were varying on the structure within the time (e.g. cantilever construction method) is particularly recommended Annex KK.101, of the Eurocode 2 approach [4].
As the main purpose of the laboratory tests were acquiring the real values of the concrete basic mechanical properties and to verify the time development magnitude of time dependent strains due to the concrete creep and shrinkage effects.
The basic mechanical parameters of concrete were gained for the 7, 14 and 28 days age of concrete.
Temperature and relative humidity are important environmental factors which are affecting to the axial stresses distribution.
