Abstract:
In the present report, rGO sheets (rG1) and disk (rG2) like structures of reduced graphene oxide (rGO) were synthesized using sugar cane juice as green reducing agent. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier-transform infrared (FTIR) spectroscopy, ultraviolet-visible (UV-vis.) spectroscopy and photoluminescence (PL) spectroscopy techniques. The transition of electrons localized in different sized sub-domain of the sp2 bonded carbons having different values of highest occupied molecular orbital (HOMO) -lowest unoccupied molecular orbital (LUMO) gap may likely to be responsible for the observed PL emission in rG1 and rG2 at different excitation wavelengths. The rG1 and rG2 were also used as photocatalyst materials for the degradation of phenanthrene (PHE) under the UV irradiation. The rG2 shows better photocatalytic degradation compared to rG1 by degrading the PHE up to 30%.

RNA Structure
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
