The Effect of the Input Parameters on the Melt-Pool Temperature
This scenario was investigated by Obeidi et al. [7] during the melting of 3×3×4 mm nitinol (NiTi) testing cubes.
The latter result agrees well with that reported by Obeidi et al. [5].

Wu Y.Y. et al. [2] added nanoparticles such as CuO, TiO2 into API-SF
engine oil and reported that the nanoparticles, especially CuO particles, can improve the lubricity of
the engine oil.
S. [5] et al also found that Al/Sn and Copper Borate nanoparticles could be used as additives to improve the lubricating property of base oils.

Ti-based
bulk amorphous alloy systems, such as Ti-Ni-Cu[2], Ti-Ni-Cu-Al[3], Ti-Zr-Ni-Cu-Al[4],
Ti-Ni-Cu-Sn[5,6], and Ti-Ni-Cu-Si-B[7] etc., have also been investigated due to their
relatively lower density and/or higher specific strength.
Similar results have also been found in Fe-B[17], Fe-Ta[11], Zr-Ti-Al-Ni-Cu[10], and Ni-Zr-Ti-Si[15] systems.
Kim et. al.[6] have reported that the Ti-Cu-Ni-Sn amorphous alloys can be prepared by melt spinning technique.
The amorphous mechanically alloyed Ti50Cu35-xNi15Snx powders showed similar results as reported by Kim et. al. [6] Mechanically alloyed Ti50Cu35N15 powders, however, exhibited no glass transition behavior.

Zhang Tao et al.[5-6] reported Ni-promoted W2C catalysts for direct catalytic conversion of cellulose and polyols to lower alcohols.
Edman Tsang et al.[8-9] investigated the conversion of ethylene glycol or glycerol to methanol over a Pd/Fe2O3 co-precipitated catalyst.
Zhou Zhiming et al.[14] studied the kinetics of hydrogenolysis from glycerol to propylene glycol over a series of Cu-ZnO-Al2O3 catalysts.
To eliminate the internal diffusion influences, the Ni-Al alloy was milled and sieved to more than 200 mesh before preparation.

Ajiwe et al. [8] and Melo et al. [9] carried out an assessment of particleboards manufactured from different proportions of wood and rice husk particles and reported that the particleboard had insufficient strength due to poor bonding within the admixture.
Physical and mechanical properties of particleboards manufactured with wood, rice husk and bamboo particles in different combinations were assessed by Melo et al. [12].
According to Odusote et al. [16], this may be due to poor water retention during faster rate drying process.
According to Ndazi et al. [3], for the minimum requirement to be met, the interfacial bond strength must be increased between the rice husk and the saw dust together with the adhesives used.

Yang et al. (1982) [3] explored the dewatering effect by drying process on the physical and mechanical properties of Guizhou red clay.
Wang et al. (2011) [5] found that the shear strength of the remolded red clay was also reduced when the water content increased.
Wildenschilds et al. (2001) [13] concluded different explanations for dynamic effects during the transient flow progress.
