The hydrothermal method has been utilized to synthesize graphitic carbon nitride (g-C3N4) polymers and cobalt oxide composites effectively. weight percentage of g-C3N4 nanoparticles influenced the electrochemical performance Co3O4-g-C3N4 composite. In an aqueous electrolyte, composite electrode, produced with 150 mg nanoparticles, revealed remarkable performance. With increase in capacitive contribution electrode increased. Co3O4-g-C3N4-150 shows a specific capacitance 198 F/g. optimized...
Surface microstructure modification of metal oxides also improves the electrochemical performance oxide nanoparticles. The present investigation demonstrates how varying urea molar content during hydrothermal process altered surfaces MnCo
In this work, Ni3V2O8 (NVO) and Ni3V2O8-reduced graphene oxide (NVO-rGO) are synthesized hydrothermally, their extensive structural, morphological, electrochemical characterizations follow subsequently. The synthetic materials’ crystalline structure was confirmed by X-ray diffraction (XRD), its unique marigold-like morphology observed field emission scanning electron microscopy (FESEM). chemical states of the elements were investigated via photoelectron spectroscopy (XPS). Electrochemical...
In this paper, the mathematical theory of elasticity that enables construction representative stress functions for photoelastic experimental hybrid method (PEHM) is revisited and reviewed. PEHM has been shown as an important powerful tool used by analysts to predict state in complex engineering structures. To demonstrate utility from real applications, contact problem a mechanical seal with rectangular cross-section well plate central hole are considered. It was found when applied cross...
