Unusual infrared-absorption mechanism in thermally reduced graphene oxide
WebI suppose the presence of different type of oxygen functionalities in graphene oxide or graphite was shown at 600 cm-1 and 800 cm -1(O-H), a long peak at 1600 cm-1 with another in 1700 ( C=O), at ... WebMay 4, 2011 · We developed nanosized, reduced graphene oxide (nano-rGO) sheets with high near-infrared (NIR) light absorbance and biocompatibility for potential photothermal therapy. The single-layered nano-rGO sheets were ∼20 nm in average lateral dimension, functionalized noncovalently by amphiphilic PEGylated … WebGraphene oxide (GO) is an important precursor of graphene. Unlike graphene, GO can be dissolved and dispersed in water or in organic solvent. GO is rich with oxygen functional group such as hydroxyl and epoxy group making it high affinity with water and easy to modify its functionality and processing and far less expensive compare to graphene [1]. how do you copy a link and put it in an email
