“…Thanks to the striking combination of high specific surface area [7], chemical inertness [8], great mechanical strength [9], and excellent electrical and thermal conductivities [10], the utilization of graphene as an active support framework for functional nanoparticles (NPs) has open promising research areas. Various methods have been developed for the synthesis of graphene, through either chemical or physical routes [3,[11][12][13][14]. Among them, chemical oxidation of graphite to graphene oxide (GO), followed by reduction to produce graphene nanosheets, results to be the most appealing due to its low cost, ease, and high yield [8,15].…”

Transition metal oxides on reduced graphene oxide (TMO@rGO) nanocomposites were successfully prepared via a very simple one-step solvothermal process, involving the simultaneous (thermal) reduction of graphene oxide to graphene and the deposition of TMO nanoparticles over its surface. Texture and morphology, microstructure, and chemical and surface compositions of the nanocomposites were investigated via scanning electron microscopy, X-ray diffraction, micro-Raman spectroscopy, and X-ray photoelectron spectroscopy, respectively. The results prove that Fe2O3@rGO, CoFe2O4@rGO, and CoO@rGO are obtained by using Fe and/or Co acetates as oxide precursors, with the TMO nanoparticles uniformly anchored onto the surface of graphene sheets. The electrochemical performance of the most promising nanocomposite was evaluated as anode material for sodium ion batteries. The preliminary results of galvanostatic cycling prove that Fe2O3@rGO nanocomposite exhibits better rate capability and stability than both bare Fe2O3 and Fe2O3+rGO physical mixture.

“…Hybridization promotes synergies between the adopted dispersed phase materials, for this reason hybrid reinforcements can exhibit new structural characteristics (eg, Al 2 O 3 -GNS non-continuous network-like structure, carbon allotrope (CNT)-graphene layered structure, CNT-graphite reticulated structure) and additional synergistic properties. [80][81][82][83][84][85] Hybrid composites can exhibit superior properties compared to those exhibited by composites containing individual reinforcements at the same loading. This is due to a strong synergistic effect on the properties through the usage of hybrid reinforcements.…”

“…In comparison to single reinforced composites, hybrid composites incorporate two or more types of dispersed phases (eg, Al 2 O 3 + ZrO 2 and B 4 C + TiB 2 ) within the same matrix. Hybridization promotes synergies between the adopted dispersed phase materials, for this reason hybrid reinforcements can exhibit new structural characteristics (eg, Al 2 O 3 ‐GNS non‐continuous network‐like structure, carbon allotrope (CNT)‐graphene layered structure, CNT‐graphite reticulated structure) and additional synergistic properties 80‐85 . Hybrid composites can exhibit superior properties compared to those exhibited by composites containing individual reinforcements at the same loading.…”

The use of metal matrix composites (MMCs) in a variety of products is significantly increasing with time due to the fact that their properties can be tailored and designed to suit specific applications. However, the future usage of MMC products is very much dependent on their beneficial aspects and hence it is critical to ensure in a robust repeatable manner the superior physical property advantages compared to conventional unreinforced monolithic metal counterparts. Although numerous routes are available for production of MMC products, each of them has their own advantages and disadvantages. This article provides an overview of advanced production routes for MMCs. The discussion also highlights challenges and presents a future prospectus for MMCs. Powder metallurgy and casting routes are still extensively used for production of MMCs. Aluminum alloys are today the most commonly used matrix materials in MMC products.Carbides (eg, SiC, TiC, and B 4 C), carbon allotropes (eg, CNTs and graphene), and alumina (Al 2 O 3) are currently the most used reinforcement materials. Nevertheless, the use of nano and of hybrid reinforcements are seeing increased usage in niche applications. Additive manufacturing (AM) is discussed as a novel production route for MMC products. This process represents a promising method for the production of MMC products.

“…In recent years, the use of graphene has been applied to a variety of fields, including optoelectronics, energy storage, electronics as well as biomedical applications [20][21][22][23][24]. In many of these fields, the control of an appropriate macroscopic and microscopic structure is often of paramount importance, if not the limiting factor, in order to satisfy stringent and often contrasting technical requirements.…”
