The former takes place from the configuration reduction in the zone between particle surfaces; the latter arises from the high concentration of adsorbed charged macromolecules in the region between the particles as they come near [34].
The goals of this research are to improve the understanding of the TNP impacts on the transport of HOCs in soil under real conditions by providing preliminary data, which include the effects of the TNPs mass loading, the size of TNPs and the competitive adsorption of organic matter in soil on HOC transport in real subsurface environment.
Data Analysis Since pyrene and TCC are both HOCs, the transport of TCC in soil with the presence of TNPs may show many similarities comparing with the one of pyrene.

Attempts were made to fit experimental data to various isotherms including Frumkin, Langmuir, Temkin, and Freundlich.
The anodic half reaction involves dissolution mild steel through oxidation process as described earlier [27–29]: Fe + Cl− ↔ FeCl−(ads) FeCl−(ads) ↔ FeCl(ads) +e− FeCl(ads) ↔ FeCl+(ads) + e− FeCl+(ads) ↔ Fe2+ + Cl− Whereas, cathodic reaction involves the hydrogen evolution through reduction process according to following steps [27–29]: Fe + H+ ↔ FeH+(ads) FeH+(ads) + e− ↔ FeH(ads) FeH (ads) + H+ + e− ↔ Fe + H2 The electrochemical polarization parameters such as corrosion potential (Ecorr), corrosion current density (icorr), slope of the cathodic branch (βc) and slope of the anodic branch (βa), and corresponding percentage inhibition efficiencies (η%) were calculated by the Tafel extrapolation method and are listed in Table 4.

By refining experimental XRD data, the lattice constant of CdS unit cell can be calculated taking into account that dominant crystalline structure is zinc blende, obtaining a= 5.79 Å (value close to that of bulk CdS, a = 5.8320 Å) and an interplanar distance of ~0.334 nm, which corresponds to the zinc blende crystalline phase in the direction of the (1 1 1) crystalline plane.
Similarly, the HRTEM micrograph of the CdS:Cu NF, shown in Fig. 4b, which presents a reduction in NP size by the quantum confinement effect due to the Cu ions incorporation in the Cd sublattice.

The density, micro-hardness and yield strength data have recently been evaluated and published in a paper by Libardi et al. [24].
These large areas could be grains that have been sintered with no size reduction during mechanical milling, or could be regions of merging of several refined powders during high temperature sintering.
Data for the mean grain size of the SPS FeMo steels are those measured with TEM.

Many cases of structural collapse, in particular of steel and timber structures, can be related to the strong reduction in the material mechanical properties at high temperatures or even to its combustion occurring during a fire.
The characteristics of the design spectra and the design methods implemented in the majority of seismic codes are based on the data of recording stations which are located in far-source fields.
The collection of data for the most typical situations has given the possibility to set-up general recommendations, which could be useful for the damage prevention against catastrophic events.

Under some limiting scenarios, the obtained data strongly correspond to the published studies in the open literature. 1 Introduction Fluids are popularly grouped into Newtonian and non-Newtonian.
For both cases, growth in M causes a reduction in the heat transfer across the surface as shown in this figure.

This is because of a requirement for high efficiency and reliability for machines and structures, a long-term employment of facilities beyond their original design lifetimes in advance due to the difficulty of their replacements, such as ageing facilities that have exceeded 10 8 cycles, and also the need of lightweight components used the high strength materials for reduction of the environmental loads to the globe.
Although a large amount of fatigue data has been reported in the form of S-N curves, data in the literature is invariably limited to testing period up to 10 7 to 10 8 cycles.

Many other advantages have been found for the enzymatic process like simple separation of the catalyst and recycle it, reduction of the energy consumed, simple separation of the glycerol byproduct, and no loss of the product due to the saponification reaction [10-11].
Design of Box-Behnken method was adopted due to small number of experiments needed for calculating the lack of fit in the experimental data.
The values of pure and residual errors was found very low indicating that the experimental data is reproducible and the model educate to characterize the connection between the dependent and independent parameters. 3.2.

Despite their promising potential, nanoantennas still face several technical challenges, such as the optimization of impedance matching, reduction of power loss, and enhancement of material durability under real-world conditions.
Current research lacks sufficient empirical data from large-scale simulations or experimental tests, and quantifiable results on energy efficiency or economic feasibility are still needed.
This absence of precise data is a significant barrier to understanding the true potential of nanoantennas for large-scale architectural integration.

These SPS features result in a rapid reduction of total cycle times.
The fundamental strength mechanisms were found from the nanoindentation data, including elastic modulus, microhardness, and nano hardness.
