Due to the importance of energy storage systems based on supercapacitors, various studies have been conducted. In this research CuO, NCNO and flower like CuO/NCNO studied as a novel materials in field. The resulte showed that synthesized CuO nanostructutes morphology which by FE-SEM analisis. Further, XRD pattern confirmed crystalline properties nanocomposite, Raman verified functional groups vibrations components nanocomposite. two-electrode system at current density 4 A/g, capacitance, power density, were 450 F/g, 3200 W/kg, 98 Wh/kg, respectively. charge transfer resistances NCNO/CuO electrodes obtained 8 2 Ω respectively, show conductivity supercapacitive nanocomposite are better than pure components. Also, stability low resistance other advantages two-symmetrical electrode investigation. investigation after 3000 consecutive cycles, only 4% initial capacitance decreased.

One of the most important edible colours is used in various industries Sunset Yellow, which essential to measure according its consumption. Therefore, a new electrochemical sensor prepared food color additives this work. In study, CuNiFe 2 O 4 nanospheres prepare potent modifier for carbon paste electrode (CPE). Due environmental toxicity additives, sensitive, fast and, low-cost determination workplace environments great interest. So, modified CPE was applied as sensitivity analysis approach Yellow present Brilliant Blue and Tartarzin plasma samples. Cyclic voltammetry (CV) differential pulse (DPV) were techniques optimize measurement Yellow. The calibration curve showed linear range from 0.5 150 μ M with detection limit 0.15 Simultaneous three colors, Tartrazine, done on CPE/CuNiFe surface simultaneous received limits are 1.60 M. shows an outstanding ability sunset Sunich syrup jelly real
