“…Reinforced nano GNPs exhibited no reaction and conversion of any intermetallic compound’s groups i.e., like Al 4 C 3 . It can also be understood that absorption bands in such phenomenon may be due to the detection boundary of the FTIR process for the solid samples [ 22 , 23 , 24 ].…”

From the aspect of exploring the alternative lightweight composite material for the aerospace launch vehicle external fuel tank structural components, the current research work studies three different grades of Aluminium alloy reinforced with varying graphene weight percentages that are processed through powder metallurgy (P/M) route. The prepared green compacts composite ingots are subjected to microwave processing (Sintering), hot extruded, and solution treated (T6). The developed Nano-graphene reinforced composite is studied further for the strength–microstructural integrity. The nature of the graphene reinforcement and its chemical existence within the composite is further studied, and it is found that hot extruded solution treated (HEST) composite exhibited low levels of carbide (Al4C3) formations, as composites processed by microwaves. Further, the samples of different grades reinforced with varying graphene percentages are subjected to mechanical characterisation tests such as the tensile test and hardness. It is found that 2 wt% graphene reinforced composites exhibited enhanced yield strength and ultimate tensile strength. Microstructural studies and fracture morphology are studied, and it is proven that composite processed via the microwave method has exhibited good ductile behaviour and promising failure mechanisms at higher load levels.

Electrochemical energy conversion and storage technologies play a crucial role in ensuring a sustainable energy future. In these regards, nanostructured carbon-based materials (NCMs) are very critical in the development of novel energy technologies and devices. NCMs include CNTs, graphene, fullerene, and ordered mesoporous carbon materials, which exist in different morphologies. NCMs offer great opportunities for effective modifications through surface functionalization, doping with heteroatoms, and fabrication of composites with organic or inorganic species. Particularly, the composites of NCMs with inorganic materials such as metallic NPs, metal oxide NPs, and their other derivatives (MNPs) have gained considerable recognition in electrochemical energy applications. These materials demonstrate distinct properties, including excellent thermal and electrical conductivity, large surface area, and chemical stability. Herein, we have highlighted some of the trends and outlooks in this exciting area, including fundamentals of these substances according to material science perspective. Besides, the latest research and development of multifunctional MNPs@NCMs composites for electrochemical energy applications have also been illustrated. Particularly, the utilization of these composites from the perspective of different electrochemical energy applications has been summarized, such as energy conversion processes like hydrogen evolution reactions (HER), oxygen reduction reactions (ORR), and energy storage devices like batteries and supercapacitors.
