“…In contrast, in the case of nanostructured ones, the preferred choices are metallic (e.g., zinc oxide, copper oxide, iron oxide, silver and gold NPs), polymeric nanoparticles (e.g., liposomes, micelles, and dendrimers), and carbonaceous nanomaterials (e.g., graphene, graphene oxide, carbon nanotubes, and carbon dots) [ 16 , 17 ]. For instance, these nanostructured, microstructured, and polymeric materials have a wide variety of engineering applications, including absorbing electromagnetic waves in high frequency (GHz) requiring thin thickness, lightweight, and thermal stability [ 18 ]; coating nanomaterials with enhanced magnetic, optical, electrochemical and mechanical properties to avoid erosion and corrosion [ 19 , 20 ]; nanomaterials that could arrest the problems that affect the efficiency of Li-ion batteries and, improve the storage and delivering capacity for long term cyclability [ 21 ]; and develop potential anode materials for sodium-ion batteries [ 22 ]. Moreover, there are other exciting materials such as complex iron oxides, dielectric oxides, and superconducting oxides.…”
