The ammonia-doped-prGO/CuO nanocomposite film thickness is controlled by varying the deposition time. Morphological analysis using scanning electron microscopy (SEM) showed the formation of a 3 dimensional structure with CuO nanoparticles being homogeneously embedded in the graphene layer. Xray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Raman analysis revealed that the deposited copper was in its oxidized form, mainly CuO. The Au/ammonia-doped-prGO/CuO electrode was successfully applied for non-enzymatic amperometric detection of glucose. Under optimized conditions, the electrode exhibited a sensitivity of 1210 mu mM(-1) cm(-2) with a detection limit of 0.25 p,M (S/N =3) over a wide concentration range (0.25 mu M to 6 mM) at an applied potential of +0.50 V vs. Ag/AgCl. The electrode material displayed good stability, excellent selectivity, and accurate measurement in healthy and diabetic human serum samples. 1 aMaaoui, H.1 aSingh, S., K.1 aTeodorescu, F.1 aCoffinier, Y.1 aBarras, A.1 aChtourou, R.1 aKurungot, S.1 aSzunerits, S.1 aBoukherroub, R.  uhttps://library.ncl.res.in/content/copper-oxide-supported-three-dimensional-ammonia-doped-porous-reduced-graphene-oxide02067nas a2200181   4500008004100000245013400041210006900175260000800244300001200252490000600264520139000270100001801660700002001678700002001698700001701718700001801735856013201753       2017                        eng d00aN-doped porous reduced graphene oxide as an efficient electrode material for high performance flexible solid-state supercapacitor0 aNdoped porous reduced graphene oxide as an efficient electrode m  cSEP  a141-1490 v83 aSupercapacitors (SCs) are energy storage devices with an immense potential to resolve energy related issues. Being a low cost, durable and multifunctional material, graphene and its derivatives are the most promising candidates for SCs. Here, we report the synthesis of N-doped porous reduced graphene (N-pGr) and its use for the fabrication of all-solid-state supercapacitor (ASSC) device. The N-pGr exhibited a specific capacitance of 230 F g(-1) at 1 A g(-1) current density and good capacitance retention up to 88% even after 10,000 galvanostatic charge-discharge cycles recorded at 5 A g(-1) fabricated in a solid-state supercapacitor. The synergistic effect of the porosity and N-doping is believed to be the underlying principle for the improved charge storage ability when compared to other reports. Significantly, the porous nature of N-pGr contributes in increasing the electroactive surface area for the formation of electrical double layer as well as facilitating the faster movement of electrolyte ions inside the electrode network. N-doping is believed to change the electrical properties of the electrode material and also to participate in the pseudo-capacitance which helped to boost the overall capacitance of the fabricated device. The good capacitance retention provides the room for making robust flexible solid-state supercapacitor (FSSC) with the N-pGr material.1 aSingh, S., K.1 aDhavale, V., M.1 aBoukherroub, R.1 aKurungot, S.1 aSzunerits, S.  uhttps://library.ncl.res.in/content/n-doped-porous-reduced-graphene-oxide-efficient-electrode-material-high-performance-flexible
