Manganese redox couples are a promising candidate for flow batteries due to their low cost, ecofriendliness, high standard reduction potential, and variable oxidation states.

In this work, spherical Pt nanometer-scale particles supported on the poly (m-toluidine)/Triton X-100 film modified carbon nanotube paste electrode (Pt/PMT (TX-100)/MCNTPE) was used as a potent catalyst for electrooxidation of formaldehyde (HCHO) in both 0.5 M H2SO4 and 0.1 M NaOH solutions. The obtained results showed that utilization of TX-100 as an additive during the electropolymerization p...

Background: High concentration of salt makes biological treatment impossible due to bacterial plasmolysis. The present research studies the process of electrochemical oxidation efficiency and optimal levels as important factors affecting pH, salt concentration, reaction time and applied voltage. Methods: The sample included graphite electrodes with specifications of 2.5 cm diameter and 15 cm he...

Oxidation of formaldehyde (HCHO) is very important, owing to its use in fuel cells. Modification of electrodes surfaces is an excellent way to decrease the overpotentials as well as to increase the current density of the voltammetric response.pt as most efficient metal catalyst can easily be poisoned by product of oxidation and also it has high cost. In this work an efficient and low cost elect...

The electrochemical oxidation behavior of m-nitrophenol (m-NP) was studied comparatively on glassy carbon electrode, Pt electrode, PbO2 electrode, SnO2 electrode, and graphite electrode using cyclic voltammetry. The cyclic voltammetry measurements were performed in acidic (1 M H2SO4, pH 0.4), neutral (1 M Na2SO4, pH 6.8), and...

a fast and simple voltammetric method for the determination of methimazole in pharmaceutical products was reported. a glassy carbon electrode was pretreated by anodization at +1.75 v (vs. sce) for 5 min, followed by potential cycling in the range of 0.3-1.3 v (20 cycles). the pretreated electrode showed an excellent electrocatalytic effect on the oxidation of methimazole. compared with untreate...

Precise matching of energy supply with demand requires delicately balanced control of the enzymes involved in substrate metabolism. In response to a change in substrate supply, the nonlinear properties of metabolic control may induce complex dynamic behavior. Using confocal imaging of flavoprotein redox potential and mitochondrial membrane potential, we show that substrate deprivation leads to ...
