The preparation of polyaniline/zeolite nanocomposite coating on 304 stainless steel (304 SS) surface has studied via the galvanostatic method. The electro-generated coating was characterized by Fourier transform infrared spectroscopy (FT-IR), UV-visible absorption spectroscopy, X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM). The anticorrosion property of polyaniline/zeo...

The nanocomposites of reduced graphene oxide (rGO) supported zinc tungstate nanoparticles (ZnWO4-NPs) receive considerable attention in electro-catalytic hydrogen evolution reactions (HER) and reveal significantly higher performances than pure ZnWO4-NPs alkaline media (i.e., 0.5 M KOH electrolyte). polarization studies show that the ZnWO4-NPs@rGO exhibit low energy loss good electrode stability...

In this study, the electrocatalytic activity of nickel foam, which is activated by cobalt, molybdenum, and phosphide nanostructures, prepared plasma hydrothermal method for use in release hydrogen oxygen. The morphology crystallographic structure synthesized specimens were examined means scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction. Moreover, electrol...

Abstract Solidification of Al–Ce alloys under ultrasonic vibrations (Sonoprocessing) has a significant effect on the refining Al 11 Ce 3 intermetallic, which plays key role in controlling properties this group high-performance characteristics. In current research, as-received Al-10 wt% that were sonoprocessed different temperatures was characterized. The influence intermetallic size and distrib...

Spinel ferrites (NixFe3-xO4; x = 0.25, 0.5, 0.75 and 1.0) have been prepared at 550ºC by egg white auto-combustion route using characterized physicochemical (TGA, IR, XRD, SEM) electrochemical (CV Tafel polarization) techniques. The presence of characteristic vibration peaks in FT-IR reflection planes XRD spectra confirmed the formation spinel ferrites. oxides were transformed into oxide film o...

This work concerns the search for new ways to modify surface of biomedical Ti–13Zr–13Nb alloy applications in regenerative medicine and personalized medicine. Obtained first time, oxide nanotubes (ONTs) layers first-generation (1G) on a were produced by anodizing 0.5% HF electrolyte at 20 V 120 min. The physico-chemical characterization obtained bamboo-inspired 1G ONTs was conducted using TEM A...
