“…The MZ/2GO-Cu composite had the highest UTS, which could be because of the transfer of load from the Mg-based matrix to the GO reinforcements with much higher Young's modulus (E GNPs = 1 TPa) through the Mg/GO interfaces [19]. The interfacial attachment of the reinforcing particles with the underlying metal matrices is important for the load transfer from the Mg-based matrix to the reinforcing particles [32]. The homogenous distribution of GO as reinforcement particles in the Mg-based matrix can efficiently load-transfer from the matrix to the GO during the applied load, resulting in enhanced load-bearing ability and increased strength of the matrix.…”

Magnesium-based composites have recently been studied as biodegradable materials for preparing orthopedic implants. In this article, the graphene oxide (GO) and GO-Cu nanosystem has been homogenously dispersed as a reinforcement in the matrix of Mg-Zn (MZ) alloy using the semi powder metallurgy (SPM) method, and subsequently, the composite has been successfully manufactured using the spark plasma sintering (SPS) process. GO and GO-Cu reinforced composite displayed a higher compressive strength (~55%) than the unreinforced Mg-Zn sample. GO and GO-Cu dual nanofillers presented a synergistic effect on enhancing the effectiveness of load transfer and crack deflection in the Mg-based matrix. Besides, the GO-Cu dual nanofillers displayed a synergistic influence on antibacterial activity through combining the capturing influences of GO nanosheets with the killing influences of Cu. However, electrochemical and in-vitro immersion evaluation showed that Cu-GO reinforcement had a slightly negative effect on the corrosion behavior of the Mg-Zn sample, but the incorporation of GO enhanced corrosion resistance of the composite. Moreover, MZ/GO and MZ/GO-Cu nanocomposites showed acceptable cytotoxicity to MG-63 cells and revealed a high potential for use as an orthopedic implant material. Based on the research results, MZ/GO-Cu nanocomposite could be used in bone tissue engineering applications.

“…The poor wear resistance of Mg is attributed to its low strength, low hardness and limited work hardening [9,14]. Researchers are interested in alloying [9,15], coatings [12,16,17] and composite material production [18][19][20][21][22] to improve the wear performance of Mg alloys. Researchers generally prefer particulate reinforcements in producing Mg matrix composites due to their isotropic nature, low costs and processing advantages.…”

The demand for magnesium (Mg) alloys is increasing in many industries, such as automotive and aerospace, thanks to their low density and high specific strength. However, the poor tribological performance of Mg alloys is one of the most important disadvantages that limit their widespread use. Researchers have developed different approaches to improve the wear performance of Mg alloys, such as alloying, coatings, surface modifications and composite production. Wear performance of systems with sliding parts are crucial for a lifetime and energy efficiency. The development of Mg matrix composites can significantly reduce energy loss by reducing damage from friction and wear. For this reason, it is crucial to understand the wear behaviour of recent Mg matrix composites. The effect of different parameters such as load, sliding speed, reinforcement content, reinforcement type and temperature on the wear performance of Mg matrix composites were investigated.

“…Nanoparticles (NPs), often referred to as invisible particulate substances with a diameter ranging from 1-100 nm (nm) are of paramount relevance in the modern science (Khan et al, 2017;Song et al, 2021;Vert et al, 2012). The large surface area to volume ratio of nanoparticles made them a unique delivery and antimicrobial agents in many respect (Ingle et al, 2013).…”

The scientific explorations of nanoparticles for their inherent therapeutic potencies as antimicrobial and antiviral agents due to increasing incidences of antibiotic resistance have gained more attention in recent time. This factor amongst others necessitates the search for newer and more effective antimicrobial agents. Several investigations have demonstrated the prospects of nanoparticles in the treatment of various microbial infections. The therapeutic applications of nanoparticles as either delivery agent or broad spectrum inhibition agents in viral and microbial investigations can no longer be overlooked. Their large surface area to volume ratio made them an indispensable substance as delivery agents in many respect. Various materials have been used for the synthesis of nanoparticles with unique properties channelised to meet specific therapeutic requirement. This review focuses on the antibacterial, antifungal, and antiviral potential of nanoparticles with their probable mechanism of action.
