Xiong et al. [6] and Vestal et al. [7] have studied CoCrFeO4 alloy for their magnetic properties and estimated some interesting results.
Similar variations in TB were reported by Vestal et al.7 It is worthwhile to note that, thanks to the large anisotropy constant of the present samples, especially due to Co2+, even a small change in the particle size produces a significant modification of the magnetic properties related to the magnetization relaxation.

The aim of this paper is to introduce and production of investigate the Al-matrix composites (Al/SiC) reinforced by SiC grains.
Introduction Al/SiC composites have several advantageous properties what can be used during its application.
Table 1 shows the properties and application fields of Al/SiC composite.
The grains of Al-powder are smaller than 40 µm, and they were used in case of all products.
In addition an Al/SiC powder mix having 5% and 10% SiC-content was processed

Chang et al. used spinach extract as a sensitizer and has manage to produce a conversion efficiency of about 0.131% which is lower compared to ipomea which has an efficiency of 0.278% [6].
En Mei Jin et al. uses wormwood plant as sensitizer which has an efficiency of 0.9% compared to bamboo which only has 0.7% and maple that is 0.4% [7] while Ho Chang et al. utilized the purple cabbage as sensitizer which manage to achieved up to 0.75% of efficiency [8].

Investigation of Mechanical and Tribological Behaviour of Dual Particles Reinforced Al Matrix Composites V.
Optical microscopy analysis confirmed the nearly uniform distribution of Al2O3/Gr twin particles in Al matrix.
The nearly uniform distribution of particles in the matrix acts an obstacle that resists the plastic flow of Al matrix.
Velmurugan et al., [15] have reported the similar trend in the case of AA6061-SiC-Gr composites.

Experiment Prealloys were prepared from industrial ZL102 Al-Si alloys and strontium (Al-10%Sr).
(a),(b)0.07%Sr modified Al-Si alloys treated for 1h at 0.5V (SHE), 1M HCl.
First, Al-Si alloys were modified by Sr.
