Graphene reduced microwave
WebApr 12, 2024 · The surface of Fe 3 O 4 is coated with a thin layer, which is suggested to be a thin layer of reduced graphene oxide. The prepared magnetic Fe 3 O 4 nanoparticles can be firmly loaded on the GO surface because the carboxyl functional groups of GO react with Fe 3+ and Fe 2+ in solution to form coordination compounds under alkaline conditions. WebA low cost, with high performance, reduced graphene oxide (RGO) Ultra-wide Band (UWB) array sensor is presented to be applied with a technique of confocal radar-based microwave imaging to recognize a tumor in a human brain. RGO is used to form its patches on a Taconic substrate. The sensor functioned in a range of 1.2 to 10.8 GHz under UWB …
