The factors that control the oxidation of metals in bimetallic complexes are investigated in relation to the possibility of developing one-site addition two-metal oxidation reactions such as those that occur in the respiratory protein, hemerythrin. It is shown that the behavior of bimetallic complexes is not represented by the sum of the analogous monometallic parts because of metal and ligand ...

Oxidation of alloy often involves chemical partition and injection of vacancies. Chemical partition is the consequence of selective oxidation, while injection of vacancies is associated with the differences of diffusivity of cations and anions. It is far from clear as how the injected vacancies behave during oxidation of metal. Using in-situ transmission electron microscopy, we captured unprece...

The electrochemical behavior of ascorbic acid on a cobalt hydroxide modified glassy carbon (CHM–GC) electrode in alkaline solution was investigated. The process of the involved oxidation and its kinetics were established using the cyclic voltammetry, chronoamperometry techniques, as well as by steady state polarization measurements. The results revealed that cobalt hydroxide promotes the rate o...

the studies performed about electrochemical oxidation 2-amino-4-methylphenol indicate that ortho-quinone yielded through oxidation of this chemical compound was unstable and it could be used as michael acceptor under solvent influences, carrier electrolyte, additives and could be transformed into the various compounds in the form of 1-4 addition michael reaction. based on this, in the paper fir...

supercritical water oxidation has attracted attention of many researchers ever since the ideahas emerged about three decades ago as a promising technique in the waste managementindustry. providing more details about the behavior of a supercritical water oxidation systemunder various operating conditions and extending available data can greatly assist more accurateand reliable design of such sys...

Electrochemical analysis allows in situ characterization of solid oxide electrochemical cells (SOCs) under operating conditions. However, the SOCs that have been analyzed in this way have ill-defined or uncommon microstructures in terms of porosity and tortuosity. Therefore, the nano-scale characterization of SOCs with respect to three-phase boundaries has been hindered. We introduce novel in s...

The electrochemical behavior of sanguinarine, a quaternary benzophenanthridine glycoside alkaloid with antimicrobial, anti-inflammatory, antioxidant and/or immune-stimulatory activities, was studied at a glassy carbon electrode using cyclic, differential pulse, and square wave voltammetry. The oxidation of sanguinarine is a quasireversible, diffusion-controlled process and occurred in a cascade...

The 3+ and 2+ oxidation states of europium have drastically different magnetic and spectroscopic properties. Electrochemical measurements are often used to probe EuIII/II oxidation state changes, but a full suite of spectroscopic characterization is necessary to demonstrate conversion between these two oxidation states in solution. Here, we report the facile conversion of an europium(III) tetra...

A recently constructed polyglycine modified carbon paste electrode (PGMCPE) was employed to evaluate the electrochemical behavior of methyl orange (MO). The developed electrode was characterized by FESEM to understand the morphology of the modified electrode and bare carbon paste electrode (BCPE). The modified electrode exhibits an excellent electrochemical activity towards the oxidation of MO....
