Khan et al. [2] developed a simple synthetic method by using a combination of 48% HBr & 30% H2O2 in the oxidation of EB in the presence of biphasic (dichloromethane–water) system at room temperature.
Shaabani et al. [3] introduced cobalt(II) phthalocyanine (Co-Pc) as a catalyst for clean and conducive method under neutral and gentle reaction condition using ionic liquid 1-butyl-3-methyl-imidazolium bromide ([bmim]Br) as solvent and oxygen as oxidant.
Biradar et al. [6] shown that the catalytic activity of Au/SBA-15 in the oxidation of EB depends on the size of Au nanoparticles.
Habibi at el. [9] shown that Mn supported on SiO2-Al2O3 catalyst converted EB only 19% with 50% yield of ACP at 250 C for 10h.

Wittner et al used fungi with a combination of CuSO4 and MnSO4 for lignin degradation and gave effective results.
While the pull out test refers to the same test carried out by Oushabi et al
The decrease in lignin levels obtained was not as large as that obtained by Bari E, et al, which was 38.29% with the same duration of exposure for 30 days [5].
This is in line with Latif R et al., who has reported that treatment on the surface of the fiber will make the fiber rough and increase the coefficient of friction [16].

Experimental Procedure
Ten specimens of each of Aluminum (Al), Brass (Cu) and Steel (St) were machined at the same conditions.
Typical measurement results for Al sample with different cutting speeds (a, b, c and d) 4.
Increasing the feed rate, particularly, when cutting Al or Cu (Fig.2c & 2d) causes greater errors.

In is isoelectronic with Al so that In diffusion can be
considered as self-diffusion of Al.
Figure 5 shows a bright field image (BFI) of (a) Cu, (b) Zn, (c) Al, and (d) Pb nanoparticles after oxidation in air at 373 K for 3.6 ks (Cu), 423 K for 3.6 ks (Zn and Pb), and at 295 K for 120 s (Al).
Similarly, hollow Al-oxides were formed after the oxidation of Al nanoparticles below about 8 nm in diameter.
The formation of hollow Cu, Zn, and Al oxides seem to be due to the same mechanism.
Moore and E.L.

According to Hench et al., the HCA formation takes place through a sequence of reactions between the implanted material, the surrounding tissues and the physiologic fluids, based on ion exchange, dissolution and precipitation steps [5].
