In good agreement with Wirnsberger et al [14], we find that the response times of SO-doped mesostructured 2D-hexagonal materials (k = 0.15 s-1 for the thermal fading kinetics) compare well to that observed for soft sol-gel matrices (k = 0.22 s-1) prepared by hydrolysis of organosilanes showing that the mesostructured silica/block copolymer films are good hosts for photochromic dyes.

Increase in the amount of silicon carbide particles and decrease in the size of the silicon carbide particles will improve hardness and consequently improves the compressive strength of Al–SiC composite [3-4].

Photoluminescence (PL) and electroluminescence (EL) of Er doped Si have widely been studied [1-5].
In the early time of 1960s, several researchers have partially estimated the lateral spread of implanted ions as well as the projected range and the projected standard deviation , based on the theory of Lindhard et al. [6] (LSS theory).
The He stopping power used here was presented by Chu et al.’s book [17].

The data on the phase diagram of Cu–O system are generalized by Clavaguera-Mora et al. [12], according to this data, for the temperature of 1100 °С the oxygen solubility in the copper melt comprises 0.64 % wt; for 1200 °С – about 1.66 % wt; for 1300 °С – about 3.10 % wt.
Hao et al. [15] present a calculation diagram of the Cu–Na system, according to which this system has a stratification of the molten metal of the monotectic equilibrium temperature of 1084.3 °С.

Given the content of calcium carbonate, calcium oxide is the reactive leading to the formation of anorthite: ((Al2Si2O8) C), wollastonite (Ca [SiO3]) and gelenita (Ca2 Al (AlSi7)) [6].
