This article describes the best corrosion inhibition behavior and adsorption of newly synthesized amino tetrazole using electrochemical computational methods.
Scanning electrochemical microscopy (SECM) is widely used to measure local reactivity of corroding surfaces. A major criticism using SECM in feedback mode for corrosion studies the requirement an external redox mediator (RM) as it could react with metal and affect Nernst potential at metal-solution interface. Consequently, becomes challenging differentiate interference caused by RM from metal. Herein, a multiscale approach presented investigate effect choice on substrate. Two common RMs,...
Scanning electrochemical microscopy (SECM) is a popular tool to study corrosion with high spatial resolution. The feedback mode of SECM involves the use an added redox mediator in solution probe local surface kinetics. Depending on mediator's oxidation state and formal potential, as well corroding metal's electroactive species can potentially polarize substrate alter behavior at macro and/or microscale. Therefore, choice material dependent. This explored methyl viologen (MV) ideal for...
Melanins are conjugated biopolymers with varying compositions and functions, found in various tissues throughout the body. Here, polymers derived from homogentisic acid (HGA), polyHGA (a simplified model of pyomelanin), formed an ex vivo tendon examined a view to understanding interactions between melanins extracellular matrix (ECM) using selection different analytical techniques, including spectroscopy (energy dispersive X‐ray, infrared, Raman), X‐ray diffraction, microscopy (electron,...
Purpose This paper aims to investigate the galvanic corrosion of titanium/L 316 stainless steel, by electrochemical noise (EN), impedance spectroscopy (EIS), and anode/cathode area ratio effect on behavior couple. Design/methodology/approach The EN measurement was employed examine effects anode cathode between steel L titanium in artificial seawater. Current potential were monitored simultaneously using a three‐electrode configuration under open‐circuit condition. resistance evaluated as...
Cu nanoparticles (NPs) have been shown to be excellent electrocatalysts, particularly for CO2 reduction - a critical reaction sequestering anthropogenic, atmospheric carbon. Herein, the micro interface between two immiscible electrolyte solutions (ITIES) is exploited simultaneous electropolymerization of 2,2':5',2''-terthiophene (TT) and Cu2+ generating flexible electrocatalytic composite electrode material. TT acts as an electron donor in 1,2-dichloroethane (DCE) through heterogeneous...
3-(4-Iodophenyl)-2-imino-2,3-dihydrobenzo[d]oxazol-5-yl 4-methylbenzenesulfonate (4-IPhOXTs) was synthesized and its inhibiting action on the corrosion of stainless steel 316L (SS) in sulfuric acid investigated by means potentiodynamic polarization electrochemical impedance spectroscopy (EIS). The results investigation show that this compound has excellent properties for SS acid. Inhibition efficiency increases with increase concentration inhibitor. adsorption 4-IPhOXTs onto surface followed...
Nanoparticle (NP) embedded conductive polymer films are desirable platforms for electrocatalysis as well biomedical and analytical applications. Increased catalytic performance is accompanied by concomitant decreases in NP size. Herein, highly reproducible electrogeneration of low dispersity Au nanocluster ultra-thin (∼2 nm) at a micro liquid|liquid interface demonstrated. Confinement micropipette tip facilitates heterogeneous electron transfer process across the between two immiscible...

Gold nanoparticles (NPs) have become ubiquitous owing to their stability, plasmonic and catalytic properties, as well biocompatibility, such that intensive research has been conducted with the aim of controlling final NP size morphology. Since 1990′s, liquid/liquid interface a means generating Au NPs via dissolution salts in aqueous phase hydrophobic capping agents into organic phase. Herein, by employing micro between two electrolytic solutions (ITIES), specifically water/1,2-dichloroethane...
The mechanism of particle-particle interface (PPI) corrosion observed in cold sprayed (CS) Cu immersed dilute HNO3 has been elucidated. PPI is initiated by the oxide inclusions present along PPIs. accelerated rate at PPIs results from combined effects confined geometry and catalytic reactions, which involve electrochemical dissolution reduction NO3−. Annealing CS 600°C coalesces inclusions, thereby breaking interconnected inclusion network. As a result, propagation impeded.
