“…Due to the high thermal properties, researchers have utilized carbon nanomaterials as nanoparticles in preparing nanofluids. Many results of the thermal conductivity enhancement of nanofluids containing carbon nanomaterials have been previously reported [ 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 , 117 , 118 , 119 , 120 , 121 , 122 , 123 , 124 , 125 , 126 , 127 , 128 , 129 , 130 , 131 , 132 , 133 , 134 , 135 , 136 , 137 , 138 , 139 , 140 , 141 , 142 , 143 , 144 ]. In this work, we review remarkable studies and provide summaries for two main types of carbon nanomaterials namely graphene and CNTs.…”

“…The thermal conductivity was significantly improved from 2.6% to 69.31% as the temperature increased from 20 °C to 100 °C, for 0.01–0.1 wt% of graphite nanoparticles (GNPs). Kim et al [ 110 ] examined the dependence of the thermal conductivity on the graphene particle size and concluded that decreasing the average particle size would result in an increase of thermal conductivity. Abdulla et al [ 111 ], Ghozatloo et al [ 112 ], and Gandhi et al [ 113 ] investigated nanofluids prepared by dispersing the functionalized graphene in water without any surfactants and found that the thermal conductivity was substantially enhanced even at a lower concentration.…”

Recently, many scientists have been making remarkable efforts to enhance the efficiency of direct solar thermal absorption collectors that depends on working fluids. There are a number of heat transfer fluids being investigated and developed. Among these fluids, carbon nanomaterial-based nanofluids have become the candidates with the most potential by the heat absorbing and transfer properties of the carbon nanomaterials. This paper provides an overview of the current achievements in preparing and exploiting carbon nanomaterial-based nanofluids to direct thermal solar absorption. In addition, a brief discussion of challenges and recommendations for future work is presented.

“…The immobilization of CNT and Gr in metallic biomaterials prevents the exposure of adjacent tissues, therefore providing biosafety for these kinds of particles [47]. It is worth noting that the application of biodegradable Mg-GFN composites fabricated through various fabrication procedures and structural modifications for load-bearing implant process for bone substitution and reproduction attracts a huge amount of attention [166][167][168][169][170][171][172][173][174][175][176][177][178][179][180]. Taking into consideration the outstanding biological response and incredible mechanical characteristics of Gr, as described in earlier sections, it is anticipated that a number of implants and scaffolds will be created in the near future.…”

Together with the enhancement of the load-bearing implant process for bone substitution and reproduction, an increasing requirement was observed concerning biodegradable magnesium and its alloys with lighter density and outstanding characteristics. Regardless of the current great potential of Mg utilization currently, the broader use of Mg alloys continues to be constrained by several natural causes, such as low resistance of corrosion, inadequate mechanical integrity during the healing process, and poor antibacterial performance. In this perspective, Mg-based composite encapsulated within graphene family nanomaterials (GFNs) such as graphene (Gr), graphene oxide (GO), graphene nanoplatelets (GNPs), and reduced graphene oxide (rGO) as reinforcement agents present great antibacterial activity, as well as cellular response and depicted numerous benefits for biomedical use. Magnesium matrix nanocomposites reinforced with GFNs possess enhanced mechanical properties and high corrosion resistance (low concentration graphene). It is worth noting that numerous elements including the production technique of the Mg-based composite containing GFNs and the size, distribution, and amounts of GFNs in the Mg-based matrix have a crucial role in their properties and applications. Then, the antibacterial mechanisms of GFN-based composite are briefly described. Subsequently, the antibacterial and strengthening mechanisms of GFN-embedded Mg-based composites are briefly described. This review article is designed to wrap up and explore the most pertinent research performed in the direction of Mg-based composites encapsulated within GFNs. Feasible upcoming investigation directions in the field of GFN-embedded Mg-based composites are discussed in detail.

“…Kim et al 88 used wet-milling via a planetary ball-mill to produced GFs which were then used for nanofluid application. It was found that 600 rpm of the planetary ball-mill yielded to larger particle size GFs (757.5 nm) than 200 rpm (328 nm).…”
