Corrosion Protection of Stainless Steel by TiO2/g-C3N4 Composites under Destructive Acidic Environment

Sharifa Al Rawahi, Dalal Al Busaidi, Isehaq Al Nafai et al. · Sultan Qaboos University Journal for Science · 2026 · 10.53539/2414-536x.1420

The corrosion inhibition competency of titanium oxide/graphitic nitride composites coated with stainless steel substrate (TiO2/g-CN/SS) were investigated in 1.0 M of HCl solution. TiO2 nanoparticles of different loads were applied as supplementary ingredients to improve the corrosion resistance of native graphite carbo …

An efficient sensor based on anodic activation of graphene oxide for sensitive and selective determination of dopamine in blood serum

Emad A. Khudaish, Lamiya Al Ghafri, Nusiba Al Hatmi et al. · Sultan Qaboos University Journal for Science · 2023 · 10.53539/squjs.vol28iss2pp17-27

A native graphene oxide (NGO) prepared by Hummers modified method was used as the template materials for the fabrication of electrochemically oxidative graphene oxide (OGO) onto a glassy carbon electrode (GCE). The fabrication of OGO-GCE persuaded via anodic reversible potentiodynamic of NGO base surface materials that …

A Surface Network Based on Polytyramine/ Gold Nanoparticles: Characterization, Kinetics, Thermodynamics and Selective Determination of Norepinephrine

Emad A. Khudaish, Arwa Al-Maskari · Sultan Qaboos University Journal for Science · 2021 · 10.53539/squjs.vol26iss1pp8-21

A solid-state sensor was fabricated by a spontaneous electrochemical deposition of polytyramine (Ptyr) film onto a glassy carbon electrode (GCE) which was further peripherally supported by gold nanoparticles (AuNPs). The surface materials of the developed sensor (AuNPs.Ptyr-GCE) were characterized by X-ray photoelectro …

Fabrication and surface characterization of poly(4-aminodiphenylamine) film modified electrode and its application for lead and cadmium determination

Mohammed M. Al-Hinaai, Salim Hamood Al-Harthi, Emad A. Khudaish · Sultan Qaboos University Journal for Science · 2014 · 10.24200/squjs.vol19iss1pp43-53

Poly(4-aminodiphenylamine), Padpa, film was synthesized electrochemically on a glassy carbon electrode by potentiodynamic repetitive cycling of 4‑aminodiphenylamine (4adpa) in 1.0 M HCl. The mechanistic steps involved the oxidation of the protonated monomer to diimine species which underwent dimerization process to for …
