Current techniques for removing the cladding can be divided into mechanical and chemical methods.
To investigate the effect of acetone and methanol on the side lighting properties of POF-incorporated PET fabric, both surface morphology and side illumination behavior were studied. 2.
Then, the acetone/methanol etching would not significantly affect practical applications.
The optical coupling effect could be one important factor.

This leads to forming a combined effect of mechanical and electrochemical interaction, resulting in much more accelerated damage comparing with the independent working.
The coating layer of the NiCrBSi material appears to be more affected as compared to the NiCrMoNb coating.
In contrast, the coating layer of the NiCrMoNb material appears to be less affected, and it is characterized by small size and uniform distribution of cavities.
Surface roughness is known to be an important factor that affects positively the resistance of the material surface to cavitation.

The application of the fluid conveying pipe includes the appropriate determination of the vibration properties of the fluid conveying system such as natural frequency, stability, and critical flow velocity.
A time dependent viscosity factor was introduced to the viscoelastic foundation model to account for the viscoelastic behaviour.
Various studies have shown that these parameters significantly affect the inherent rate of occurrence and velocity of internal fluid flow.
Thus, a decrease in the foundation viscous coefficient leads to an increase in the dynamic properties of the pipe system.

Each colour represents a shape Formability and material properties.
Specific materials and material properties.
The majority of experiments investigating formability and material properties have been done with pure aluminium.
Although it can improve surface finish and reduce production time by allowing larger vertical step sizes without affecting surface quality, increases in tool diameter give much higher forces and can be a limiting factor.

The first one appeared in 1978 and it focused chiefly on the physic-chemical properties of radon, its occurrence in the environment and environmental impact.
The other book was published in the 21st century and it contains an extensive review of the most important information on radon with special emphasis on its physicochemical properties, particularly radioactive properties.

Because of its biocompatibility and osteoconductive properties, it has been extensively investigated for medical applications [1,2].
Such substitutions have much influence on the physical and chemical as well as physiochemical properties of apatite.
It was reported that the substitution of fluorine for OH- sites and formation of fluoride-substituted hydroxyapatite or fluoro/hyroxyapatite (FHAp) enhanced the acid resistance and the mechanical properties of hydroxyapatite, and induced better biological response [24,25].
As the amount of fluoride affects the properties of hydroxyapatite.

The studies have shown that microstructure and microchemistry of the underlying alloy can affect the characteristics of the oxide and in turn the transport of hydrogen through the oxide and into the underlying metal.
Two factors that may limit the lifetime of these components are corrosion and hydrogen pickup rates.
Mechanical and corrosion properties of the Zr-2.5Nb pressure tubes are strongly dependent on the initial fabrication route and subsequent treatment of these tubes.
Results and Discussion Although both m and ysc specimens exhibited Laue patterns indicative of single crystal properties (Fig. 1), the diffraction spots obtained from the m specimens (Fig. 1b) were rather dispersed.
In the case of β-annealed Zr-20Nb oxides such properties have been observed [3].
