This research addresses the need for effective corrosion inhibitors in industrial applications, evaluating performance of 4-nitro-2-(((1E,2E)-3-phenylallylidene)amino)aniline (noted as 3ph-Schiff base) a inhibitor comparison to benzotriazole (BTA) high-concentration 3 M HCl environment. Unlike studies conducted lower concentrations (e.g. 0.1 and 1 M), this study aims assess under more aggressive conditions. Rigorous methods, including Tafel polarisation, electrochemical impedance spectroscopy (EIS), mass loss measurements, revealed variations inhibition efficiency (IE). Polarisation data indicated that base at 0.3% (approximately 8.96 mM) achieved maximum IE 99.5%, surpassing BTA same concentration 25.2 mM), which recorded an 96.9%. Meanwhile, EIS analysis yielded slightly values, with reaching 90.21% 67.39%, reflecting complementary nature these methods. The mechanism is attributed strong adsorption on metal surface, where amino (NH 2 ) nitro (NO groups promote stable complex formation ions, enhancing electron donation forming protective layer blocks corrosive agents. Scanning microscopy elemental mapping confirm uniform nitrogen carbon surface coverage, integral layer. acts both physical barrier passivator, effectively reducing anodic cathodic reactions. combined effects adsorption, blocking passivation underscore base's superior acidic environments.

Flexible photodetectors have garnered significant attention in recent years due to their vast potential. Among these, amorphous Ga2O3 (a-Ga2O3) stands out as a highly promising candidate for flexible solar-blind ultraviolet photodetectors, owing its wide band gap, low-temperature fabrication advantages, and exceptional stability under extreme conditions. However, the of a-Ga2O3 inevitably introduces oxygen vacancy (VO) defects, leading declined photodetection performance compromised corrosion resistance. In this study, we developed zirconium (Zr) self-compensation doping strategy with concentration optimization suppress VO thus enhancing optoelectronic durability photodetectors. The introduction Zr significantly eliminated intrinsic defects films, lowering dark current by over 3 orders magnitude from ∼10-8 ∼10-11 A reducing response time factor 50, achieving 6 μs. detectivity optimized devices reached high level × 1014 Jones, indicating sensitivity light. Durability tests further demonstrated that exhibited outstanding mechanical robustness, maintaining 95% initial after 10,000 bending cycles, stable even harsh salt spray conditions 72 h. This work provides an effective solution developing high-performance tailored wearable applications environments.
