Voltammetric determination of all DNA nucleotides.
TL;DR: The voltammetric oxidation of all deoxyribonucleic acid (DNA) monophosphate nucleotides is investigated for the first time over a wide pH range by differential pulse voltammetry with a glassy carbon electrode.

Simultaneous determination of guanine and adenine in DNA using an electrochemically pretreated glassy carbon electrode
TL;DR: A simple and reliable method based on adsorptive stripping at an electrochemically pretreated glassy carbon electrode (GCE) was proposed for simultaneous or individual determination of guanine and adenine in DNA.

Electrochemical Oxidation of 8-Oxoguanine
TL;DR: In this article, the mechanism of guanine oxidation on glassy carbon was investigated and it was shown that it is a reversible electrode process, pH dependent, and involves several reaction products.

Direct electrochemistry of DNA, guanine and adenine at a nanostructured film-modified electrode.
TL;DR: Using the MWNT-modified GCE, a sensitive and direct electrochemical technique for the measurement of native DNA was developed, and the value of (G+C)/(A+T) of HCl-digested DNA was detected.

Quantifying sonochemistry: Casting some light on a ‘black art’
TL;DR: In this article, the Undatim Sonoreactor probe system is used to reproduce chemical reactions performed in ultrasonic baths. But the results of some model reactions performed using the newly developed UndatIM Sonoreact probe system have sometimes proved difficult to reproduce, due to a failure of the original report to specify the exact sonication conditions, e.g., the frequency of ultrasonic irradiation, the precise power entering the reaction system, the geometry of the reaction vessel, the presence of a bubbled gas or even the temperature of the reacted reaction.

TL;DR: In this paper, carbon electrodes were irradiated with 20-kHz ultrasound from a 475-W generator in dioxane and shown to exhibit enhanced heterogeneous electron-transfer rates for a variety of aqueous redox probes.

TL;DR: In order validly to correlate quantum mechanically calculated data for the energy required to add or remove an electron to or from the outermost electron level of each molecule, with electrochemical redox potentials (in solution), the effects of adsorption, electron-transfer reversibility and solvation energy must be considered.
