The electrochemistry of disulfides incorporated into the sugar-phosphate backbone of pyrene-modified DNA has been examined on highly oriented pyrolytic graphite (HOPG). Two signals, one irreversible, one reversible, are observed at -160 and -290 mV versus normal hydrogen electrode, respectively. The inclusion of a single base mismatch in the DNA duplex below the location of the disulfide leads ...

The systematic combination of N-heterocyclic olefins (NHOs) with fluoroarenes resulted in twisted push-pull alkenes. These alkenes carry electron-donating cyclicdiamino substituents and two electron-withdrawing fluoroaryl the geminal positions. synthetic method can be extended to a variety substituted by varying NHO as well fluoroarenes. Solid-state molecular structures these molecules reveal n...

For several years, electrochemistry in combination with mass spectrometry has been the subject of attention and development for studying the oxidative drug metabolism at early stages of new drug development. Though the technique could successfully imitate the in vivo oxidative drug metabolism initiated by electron transfer, it lags in the imitation of reactions initiated by either hydrogen atom...

Abstract In teaching electrochemistry, it is of primary importance to make students always aware the relations between electrochemistry and all non-electrochemical topics, which are taught. The vast majority will not specialise in but they can very much benefit from basics concepts electrochemistry. This paper aimed give suggestions how easily be interrelated topics inorganic, organic, analytic...

Abstract The electrochemistry nowadays has many faces and challenges. Although the focus shifted from fundamental to applied electrochemistry, one needs acknowledge that it is impossible develop design novel green energy transition devices without a comprehensive understanding of electrochemical processes at electrode electrolyte interface define performance mechanisms. review gives an overview...

Nitrogen reduction in mild conditions (room T and atmospheric P), using a non-fossil source of hydrogen remains challenge. Molecular metal complexes, notably Mo based, have recently shown to be active for such nitrogen fixation. In this work, we report about the electrochemical N2 splitting with MoIII triphosphino complex [(PPP)MoI3], at room temperature moderately negative potential. A MoIV ni...

We report herein the effect of palladium on the redox electrochemistry of ferrocene monocarboxylic acid encapsulated within an organically modified sol-gel glass network (ORMOSIL). It has been found that amount of palladium and its geometrical distribution significantly alter the redox electrochemistry of FcMCA. The geometrical distribution of palladium has been controlled by two methods: (i) p...

BACKGROUND It has been demonstrated that dynamic electrochemistry can be used to correct blood glucose measurement results for potentially interfering conditions, such as humidity, hematocrit (HCT) variations, and ascorbic acid. The purpose of this laboratory investigation was to assess the potential influence of hematocrit variations on a variety of blood glucose meters applying different meas...

Localized pH measurements are important in various areas of electrochemistry, from corrosion to bio-electrochemistry and electrocatalysis. Different techniques available perform these offer numerous possibilities terms spatial temporal resolution, sensitivity, precision. In this brief review we present the recent progress made summarize main for localized electrochemistry such as scanning probe...
