“…Furthermore, it contains 42 Raman active modes of 11A 1g + 14E 1g + 17E 2g . 32 The occurrence of six distinct peaks at 350 cm À1 , 414 cm À1 , 459 cm À1 , 562 cm À1 , 620 cm À1 , and 661 cm À1 in the Raman spectrum clearly indicated the formation of the SrFe 12 O 19 phase. The peaks at 350 cm À1 , 414 cm À1 , 459 cm À1 , 620 cm À1 , and 661 cm À1 were ascribed mainly to Fe-atom stretching at the octahedral sites and were categorized as A 1g symmetric stretching modes.…”

Aluminum alloys have become an essential material in many modern applications, such as automobiles, marines and aviation industries. It is expected that more applications will heavily depend on aluminum alloys to reduce the weight and maintain safety standards, many previous studies have done in this regard. Numerous of these applications’ parts could be subjected to different loading and environmental conditions. This includes wearing stress and loss of the surface properties. To address these issues, intensive researches have been conducted aiming to improve aluminum wear resistance. However, there is an increasing demand to provide a comprehensive understanding of the mechanisms of enhancing wear resistance. Preparation of nano-materials combined with aluminum alloy can be made in several known metallurgical methods. One of the most important difficulties and challenges faced in the manufacture of these nano-materials is to obtain a homogeneous mixture that does not have manufacturing defects. The present work aims to process and evaluate the Nano-hybrid composites of with different ratios of (Cu+Ti) mixed with AA7075 by using the liquid stir casting method by using (pin-on-disc) wear testing apparatus. The results showed when using multiple speeds and different loads in practical experiments, that the volumetric wear loss increase from 2.8 mm3 to 29.89 mm3 for zero–Nano and from 0.889 mm3 to 3.09 mm3 for 0.8 %+0.3 % (Cu+Ti) composite at speed 100 to 300 respectively. And from 12.81 mm3 to 0.889 mm3 at 25N. The coefficient of friction is reduced with the addition of reinforced material at 0.8 %+0.3 % (Cu+Ti) composite from 0.172 to 0.05. The hardness (BH) of the prepared composites increases with increasing the amount of hybrid Nano–reinforced materials. The enhancement percentage of 25.4 % is attained compared to the matrix material. These additions, which were in certain proportions, improved the mechanical properties

“…The third method is one-step synthesis method. [64][65][66] This method is to add different metal salts to the precursor solution at one time according to the molar ratio, and obtain the final product through gel, drying and sintering. Although the one-step synthesis method is very simple compared with the previous two methods, the composition is difficult to control, so there are not many researchers who use this method to synthesize MFe 12 O 19 -based composite photocatalysts.…”

Hexagonal ferrite (MFe12O19, M=Sr, Ba, Cu, Ni, Pb) is a kind of semiconductor material with excellent performance and an important magnetic material, with high chemical and thermal stability, low cost, simple preparation process, excellent optical, magnetic, wave-absorbing, dielectric, photoluminescence properties and catalytic activities have been widely used in broadcast communication, information storage, aerospace, automatic control, catalytic synthesis, medicine and biology and many other fields. This paper focuses on the application of MFe12O19-based ferrite in the field of photocatalysis, and further discusses the effect of preparation method on the photocatalytic activity of MFe12O19-based photocatalysts. The application of MFe12O19-based photocatalysts in the degradation of dyes, drugs and persistent organic pollutants (POPs) was deeply revealed, and the photocatalytic mechanisms of single-phase MFe12O19, ion-doped MFe12O19 and MFe12O19-based composite photocatalysts were also explored. The relationship between photocatalytic activity and photoluminescence properties of MFe12O19-based photocatalysts have also been investigated. This review points out the direction for further research on the application of MFe12O19-based photocatalysts in the field of photocatalysis.
