Herein, the electrochemical and photodegradation properties of magnesium ferrite and graphenenanoplatelets nanocomposites, (MFO)1-x(GNPs)x, (x = 0.25, 0.50, 0.75) are reported. Benefitting from the effective interfacial interaction of the bi-phase nanocomposite and superior electrical conduction of GNPs, a significant enhancement in supercapacitive performance has been demonstrated. Interestingly, the electrochemical properties of nanocomposite electrode were found to depend on the loading ratio of GNPs. Notably the (MFO)0.50(GNPs)0.50 (50 wt. % GNPs) showed an outstanding energy storage capacity of 612 F g -1 at 0.5 Ag -1 with 21.25 Wh kg -1 energy density at power density of 125 W kg -1 and retains ∼76.8% of the first cycle capacitance after continuous 1500 charge/discharge cycles. Furthermore, the (MFO)0.75(GNPs)0.25 (25 wt. % GNPs) composite demonstrates admirable photodegradation efficiency (99.3% in 60 min of visible light illumination) which is 3.2 times than that of neat MFO nanoparticles. The superior electrochemical and photodegradation performance suggest that the prepared nanocomposites can be effectively utilized in high-performance energy storage devices and low cost, eco-friendly water purification systems.

“…30 However, the actual potency of these materials was strongly dependent on n 2 for optical switching-based applications. The change in refractive index, as indicated by the thermo-optic effect, 35 occurred because of the higher thermal contribution of the non-radiative relaxation of the excited levels, which caused phase changes in the material. Optical nonlinearity is temperature-dependent, and the outcome rise in thirdorder nonlinearity.…”

“…Under CW laser illumination, the self-focusing and self-defocusing effects are usually associated with the refractive nonlinearities of thermo-optic origin. 35 In our study, we focused mainly on the doping effect of cobalt for the enhancement of third-order NLO properties. Therefore, in the current study, we attempted to dope Co in ZnO by varying weight percentages using the SP technique; to study the NLO properties, the Z-scan technique was used.…”

The organic-inorganic hybrid salt: 1, 1 -methylenedipyridinium pentacynidonitrosoferrate(II)pentahydrate is synthesized and characterized by multinuclear NMR, IR, and UV-vis spectroscopies and elemental analysis. The third order nonlinear optical properties of the new complex in an aqueous solution have been studied using Z-scan technique. Measurements were performed for input intensities (I0) of 437 and 241 W/cm 2 for the two concentrations with a CW diode laser at 635 nm wavelength. The nonlinear optical absorption coefficient (β) and nonlinear refraction (n2) are found at 1.28 × 10 −3 cm/W and 10.17 × 10 −9 cm 2 /W, respectively. The overall results suggested that better nonlinearity was observed at a higher concentration of sample. Our results suggest that this material is considered as a promising candidate for future optical device applications.
