“…As shown in Figure 2 Figure 2a represented small Zn-NPs size surrounding MWCNT compared with our previous work [32] which may be due to the change of some physical parameters such as rotational speed of the cathode and voltage of power supply [18,33]. On the other hand Figure 2b showed that MWCNT inner radius was smaller than the previous work despite of their larger outer radius (compared with others).…”

“…All the mentioned peaks were considered evident peaks indexed as the Zinc oxide wurtzite structure (JCPDS Data Card No: 36-1451) [35]. FTIR was done for each sample to confirm their chemical bond and to get more information about their structure as shown in Figure 4a representing the ZnO-MWCNT [32], (b) GO-NPs [34], and (c) for ZnO-NPs [36,37]. Each noticed peak in Figure 4 was compared with previous reported values to ensure the chemical structure of the prepared nano materials as tabulated in Table 1.…”

Toxoplasmosis may become a fatal disease in immunodeficient, diabetic patients, pregnant women, and infants. Hence, the diligent search for new effective treatment is among the major concerns worldwide. The well-dispersed multi-walled carbon nanotubes lined with ZnO (ZnO-MWCNT), graphene oxide (GO-NPs), and zinc oxide (ZnO-NPs) were successfully synthesized through rapid and facile hydrothermal arc discharge technique (HTADT). The antiparasitic effects of ZnO-NPs, GO-NPs, and ZnO-MWCNT were investigated in mice infected with Toxoplasma gondii. The percent of tachyzoites reduction were detected. The observed results demonstrated that ZnO-MWCNT revealed a significant reduction in the parasite count reached 61% in brain tissues, followed by liver (52%), then spleen (45%). The assessments of antiparasitic, inflammatory, and anti-inflammatory cytokines confirmed the superior activity of ZnO-MWCNT as antiparasitic agent, which paves the way for the employment of ZnO-MWCNT as a treatment for the acute RH strain of T. gondii infection in vivo.

“…The technique was originally used to manufacture graphene by Kratschmer et al [ 63 ]. This method has enabled the production of 2–4 layers graphene [ 64 ]. Several carbon-based nanomaterials, such as fullerenes and carbon nanotubes, have been successfully produced utilising the arc discharge technique [ 65 , 66 ].…”

“…At 50 mA/g current density, studies have shown that the lithium-ion battery’s capacity of initial discharge may reach as high as 1332 mAh/g (where graphene sheets are employed to improve the electrodes). After 300 cycles, the retention incapacity is 323 mAh/g in this scenario [ 64 ]. The cyclic stability in the test cell is significantly enhanced with high crystallinity and sufficient thermal stability of FLG.…”

Wearable sensors and invasive devices have been studied extensively in recent years as the demand for real-time human healthcare applications and seamless human–machine interaction has risen exponentially. An explosion in sensor research throughout the globe has been ignited by the unique features such as thermal, electrical, and mechanical properties of graphene. This includes wearable sensors and implants, which can detect a wide range of data, including body temperature, pulse oxygenation, blood pressure, glucose, and the other analytes present in sweat. Graphene-based sensors for real-time human health monitoring are also being developed. This review is a comprehensive discussion about the properties of graphene, routes to its synthesis, derivatives of graphene, etc. Moreover, the basic features of a biosensor along with the chemistry of sweat are also discussed in detail. The review mainly focusses on the graphene and its derivative-based wearable sensors for the detection of analytes in sweat. Graphene-based sensors for health monitoring will be examined and explained in this study as an overview of the most current innovations in sensor designs, sensing processes, technological advancements, sensor system components, and potential hurdles. The future holds great opportunities for the development of efficient and advanced graphene-based sensors for the detection of analytes in sweat.

The aluminum metal matrix composites were broadly exploited in the applications of automotive, aerospace, and other defense with functionally graded materials-related application. Above applications definitely required excellent mechanical characteristics. Therefore, in this way, the major attempt was made on the nano-based composites with aluminum alloy utilization. In this research, aluminum alloy AA8011 and the ceramic-based reinforcement particles of nano boron carbide (B4C) were selected for producing the metal matrix composites by the liquefying process or stir casting route. The weight percentage of nano boron carbide particles having 15 wt% was subjected to add into the aluminum alloy during the stir casting process. Then, processed nano boron carbide and AA8011 specimens were prepared to conduct tribological behaviors with various processing conditions like sliding velocity, setting wear temperature, and applied load by the tribometer setup. The scanning electron microscope was employed to examine the processed composites samples and worn-out surface samples. Finally, the multiobjective optimization was used to measure the individual performances of the tribological parameters by the gray relational technique.
