In the present days, CNT are highly synthesized by various popular methods which are carried out under high temperature. So, here in present work CNTs are synthesised by low temperature at 160°C with familiar hydrothermal method using precursors as Ethanol, Polyethylene Glycol (PEG) and Sodium hydroxide with reaction time of 20 hrs.

This structure has a nonlinear dielectric barrier encompassing resonance and non-resonance nonlinearity. The formation of optical solitons in the model is possible only if a certain relation exists between the propagating pulse frequency and the components that characterize the nonlinear medium. These relations are obtained by constructing the Lax pair and it is found that the obtained conditions coincide with the integrability conditions obtained from Painleve analysis. The conditions obtained for the existence of soliton solutions in a multicomponent medium are sufficiently enough as they characterize both linear and nonlinear properties of the medium. The one-soliton solution is obtained by Backlund Transformation method.

Journal of Materials Science: Materials in Electronics, 2021

X-ray diffraction (XRD) studies confirm the as-deposited CuInSe2 thin films at 85 °C without and with complexing agents belong to the tetragonal crystal structure with the dominant peak representing the (112) plane. The single crystallized CuInSe2 thin films show Raman spectra with a dominant A1 mode at 174 cm−1. Raman spectra analysis conform that doesn’t peak present secondary phases like Cu2S and In2S3. AFM images of the as-deposited thin films show adherent, compact, and crack-free surface. The (αhν)2 fall is sharper in CuInSe2 thin films with TEA complex than the TMAH complex due to better crystallinity. From the electrochemical impedance spectroscopy (EIS) study, we found that CuInSe2 thin film with TEA complex acquires a very slighter charge transfer resistance (Rct) of 32 Ω when compared with CuInSe2 thin film samples deposited with and without TMAH. Also, photoelectrochemical investigation signifies that CuInSe2 thin films deposited with TEA complex exhibit engendering better photocurrent response and more rapid relocation of photo-induced charge carriers in contrast to the other thin films fabricated with TMAH. We observed from cyclic voltammetry (CV) studies that redox reaction of iodide/triiodide (I−/I−3) optimized using CuInSe2 thin film with TEA complex delivers superior electrocatalytic performance than the films with TMAH.

It has been observed from CV analysis; the optimized 3 mol% Ni2+-doped FeS2 thin film delivers superior electrocatalytic performance of triiodide reduction.
