Aim of the present communication is to show experimental results, and related conclusions, on the electrochemical oxidation (EO) of tartaric acid (TA), which has been oxidized at Ti/PbO2, Ti/Pt, Pt and HBDD electrodes at different current densities in acidic media. TA complete mineralization has been achieved only at HBDD and Ti/PbO2, being higher the faradaic efficiency at the latter electrode. At Pt electrode, the electroxid Read More

Comninellis and his research group have elucidated a theoretical model that permits us to predict the chemical oxygen demand (COD) and instantaneous current efficiency (ICE), during the electrochemical oxidation of organic pollutants on a synthetic boron-doped diamond thin film electrodes (BDD) in a batch recirculation system under galvanostatic conditions. Several studies highlight the good correlation between t Read More

The kinetics of the electrooxidation of m-cresol in aqueous solution was investigated in a one-compartment flow electrochemical cell with a boron-doped diamond electrode (BDD). Cyclic voltammograms recorded on BDD revealed that cresol oxidation takes place at a potential very close to the discharge of water. Under potentiostatic conditions, at a working potential lower than water discharge, a passive layer was rapidly form Read More

The electrochemical degradation of nitrobenzene in undivided and divided cell using Ti/SnO2-Sb2O5 anode was studied. The electrochemical degradation of nitrobenzene is of the results together by anode and cathode. Two general possible paths of the electrochemical degradation of nitrobenzene are proposed: (1) Nitrobenzene was first oxidized to p-nitrophenol. Then p-nitrophenol was degraded to hydroquinone, ben Read More

Electrochemical oxidation of 3-chloropyridine (3-ClPYR), as a model pollutant, on a modified β-PbO2 electrode was examined by bulk electrolysis. Parameters affecting the removal and reaction rate of 3-ClPYR, such as current density, pH and initial concentration, were investigated. The results showed that 3-ClPYR could be readily decomposed under the attack of hydroxyl radicals (·OH) electrochemically generated on the modif Read More

Anodic oxidation is a promising process for degrading toxic and biologically refractory organic pollutants present in wastewater. Proper selection of electrodes is the key to reach effective and economic treatment. In this study, the electrochemical oxidation of Alizarin Red has been studied in neutral media using lead dioxide (PbO2), boron-doped diamond (BDD) and platinum (Pt) anodes in bulk electrolysis experiments under s Read More

Steviol glycosides, a collection of natural sweeteners extracted from the leaves of the Paraguayan shrub Stevia rebaudiana, have been drawing an increased amount of attention in the last decades. Very recently, the steviol glycosides were approved as a novel food additive in the European Union, which resulted in a growing interest by the general public. The structure of the steviol glycosides consists out of a diterpene ent-k Read More

C5-position in pyrimidine nucleosides and nucleotides is an invaluable anchor point for tagging diverse kind of labels like haptens, dyes and signaling molecules. Oligonucleotides with such C5-modified pyrimidine nucleosides and nucleotides are being used in molecular genetics and next generation nucleic acid sequencing as indispensable diagnostic tools. In view of their requirement in a wide range of primers and probes Read More

The organic electroluminescent (EL) technology, which has been the research focus in the field of electro-optical information, holds a wide range of potential application in domains of communication, information, display, illumination and so on. Organic EL materials have many advantages when compared to their inorganic counterparts. Carbazole, as a kind of rigid plane biphenyl compound with wide band gap, high luminescent Read More

This review presents the organic compounds and reactions in which boronic acids are featured together with chalcogens. Structurally varied sulfur-, selenium- and tellurium-containing boronic acids are described. Survey of their preparation methods as well as the scope of applications in organic, medicinal, analytical and supramolecular chemistry is provided. Reactions involving both the boronic acids and chalcogen-containing co Read More

Natural products have not only yielded new and effective drugs but have also provided insight into new mechanisms of action. Paclitaxel (Taxol) as the first promoters of tubulin polymerization plays important roles in the war against cancer and in the exploring new microtubule-binding drugs. The present review summarized the development of paclitaxel and its analogues which can be used as the precurce of synthesis of Taxo Read More
