A Study on Electrochemical Behaviour of Sodium Saccharin in an Aqueous Electrolyte Solution Using Cyclic Voltammetric Technique by a Nano-sensor

It used a nano-sensor of the chemical compounds consumed by diabetic patients as a substitute for natural sugar to detect the electrochemical characteristics of sodium saccharin in different electrolytes. The cyclic voltammetric method was used to examine sodium saccharine in different electrolytes, with the working electrode (CNT/GCE) being a modified glassy carbon electrode (GCE) incorporating…

A Mechanistic Insight into Oxidative Degradation of Favipiravir by Electrogenerated Superoxide through Proton-Coupled Electron Transfer

This study provides a mechanistic understanding of the oxidative degradation of favipiravir by electrogenerated superoxide via proton-coupled electron transfer. The oxidative degradation of pyrazine antiviral drugs, 3-hydroxypyrazine-2-carboxamide (T-1105) and 6-fluoro-3-hydroxypyrazine-2-carboxamide (favipiravir, T-705), by the electrogenerated superoxide radical anion was investigated using electrochemical analyses aided by density functional theory calculations (O2-). T-1105 and T-705 are antiviral…

A Mechanistic Insight into Superoxide Elimination by Mesalazine through Proton-Coupled Electron Transfer

This study elucidates a molecular understanding of how 5-amino-2-hydroxybenzoic acid eliminates the superoxide radical anion (O2•) (mesalazine, 5-ASA). Using cyclic voltammetry and electron spin resonance (ESR) investigations supplemented by density functional theory (DFT) calculations, the removal of O2• by 5-ASA, 4-amino-2-hydroxybenzoic acid (4-ASA), and related drugs used for ulcerative colitis treatment was examined. The chemicals…

Preparation, Physical and Electrochemical Characterization of Nickel Cobaltites, NixCo3-xO4 (0 ≤ x ≤ 2.5): A Recent Study

Mixed oxides of spinel type NixCo3-xO4 with 0 ≤ x ≤ 2.5 have been synthesized via several methods. We used X-ray diffraction, the Brunauer-Emmett-Teller process, and scanning electron microscopy to look into their physicochemical properties To investigate their electrocatalytic performances, cyclic voltammetry, steady-state measurements, and roughness factor were used. According to the X-ray diffraction patterns,…

A Comparative Study of Two Different Media Effect on the Electropolymerization of 2-(9-ethylcarbazol-3- yliminomethyl)phenol by Cyclic Voltammetry, Impedance Spectroscopy, XPS, UV-visible Measurements and DFT Calculation

A carbazole-based monomer, 2-(9-ethylcarbazol-3-yliminomethyl)phenol (SIC), was first synthesized and characterized. It was afterward polymerized by potentiostatic methods. Oxidative polymerization of SIC was carried out in two media. The first one (i.e. Bu4NBF4 (0.1M)/MeCN) gives the poly(2-(9- ethylcarbazol-3-yliminomethyl)phenol). However, the second one (LiClO4/MeCN + 35mM HClO4), leads to another polymer, the poly(2-(9-ethylcarbazol-3-yliminomethyl)cyclohexa-2,5-diene-1,4- dione).These two novel polymers…
