Thus, SERS and SEHRS can appear at comparable signal levels because of strong surface-enhancement factors.
To the extent, Kneipp et al. reported the enhancement factor on the order of 1020 comparing the near-infrared (NIR)-SERS enhancement factors of crystal violet on colloidal silver clusters [53].
Single molecule surface-enhanced Raman scattering (SM-SERS) The observation of a single molecule and its individual properties and structural transformation can provide useful insight related to intrinsic characteristics that cannot be studied in an ensemble of molecules due to averaging.

Steel is typically regarded as a more cost-effective and preferred building material in industrial sectors [4-5], because mild steel is inexpensive and has excellent mechanical properties.
The widespread use of mild steel is linked to its appealing qualities, which include strength, durability, excellent mechanical and chemical properties, availability, and a relatively low cost of manufacturing [1, 6–8].
This is a widespread issue that not only increases the risk of accidents because of a decline in mechanical properties but also results in significant financial losses.
It functions as a wetting surfactant with surface tension-lowering properties [21, 40].

Known amounts of enzyme preparation were transferred to several polypropylene vessels, each containing 1 mL 5 mM potassium phosphate buffer pH 6.5 and a small mechanical stirrer.
Since the surface properties of the PHD would change with the pH environment, as an important factor affecting the binding and activity yield of immobilized enzyme, the process of immobilization PGA was studied.

Cathode material is an important factor that determines the capacity and life of a battery [2].
Their coating improved the cycle performance and storage properties of NMC811.
This indicates that the coating of rice husk derived silica to commercial NMC811 surface does not affect its crystal structure.
Characterization using XRD shows that silica coating does not affect the NMC811 crystal structure.

Introduction
The evaluation of the microstructure development during and after hot deformation of metals has practical importance due to its relationship with the mechanical properties of final products.
Flow stress during the hot rolling simulation process In order to validate the flow stress obtained on the basis of given flow curves, rolling forces during the hot rolling simulation and laboratory rolling test were compared for finishing rolling stages, as the flow stress is normally the most important factor affecting the rolling force during finish rolling (Fig. 10).

This
favourable microstructure has lead to the development of the FSW operation into a processing operation known as friction stir processing (FSP) which is carried out on monolithic work pieces in
order to enhance their material properties.
Friction stir welding has been shown to be a viable method of joining superplastic materials by enabling the retention of existing superplastic properties within the weld region.
Welds in AA2004 are able to retain superplastic properties allowing uniform deformations of >200%.

This owes mainly to the fact that their study entails the observation of complex dynamic phenomena, like recrystallization or grain growth, where the motion of grain boundaries is influenced by a multitude of factors that complicate the association of its fundamental dependences with microstructural features [5, 6, 12-16].
While grain boundary thermodynamics and kinetics have been addressed frequently in the past, very little is known of the properties of grain-boundary junctions.
These examples demonstrate that grain boundary triple lines have properties distinct from those of the connected grain boundaries.
Hertz considered the geometrical and mechanical behaviour of two spherical bodies under a load.
This factor may be a reason for the abnormal stability of small voids in nanocrystalline materials.

The sprayed particles size
distribution is also very important for coating properties [189].
Coating properties.
It has been found that this transition temperature depends on numerous factors: i) the modification of the substrate surface wettability, ii) desorbtion of adsorbates and condensates and iii) solidification mechanisms [216, 220].
Nevertheless, many works are still necessary to correlate coating thermo-mechanical properties to in-flight particles characteristics as well as substrate and coating temperature during spraying.
For larger droplets, shell precipitation occurs and the particle can later fragment depending on the pressure inside the shell and its mechanical properties.

Compared with the traditional optical or mechanical stabilization techniques, EIS has advantages of real-time processing speed, high accuracy and easy implementation.
In Kalman filter, different process noise and measurement noise values will affect the filtering result.
The improved sage-Husa adaptive filter proposes the criterion [19] using the property of innovation sequence to determine whether the filter is divergent.
Zhou [20] proposes an improved sage-Husa algorithm based on covariance matching and attenuation factor.
In some camera systems of high dynamic application such as the real-time weapon targeting system, EIS is the secondary treatment after optical or mechanical stabilization.
