Electroanalysis of Cystine and Selenocystine.
Selenium was J.J. Berzelius. discovered in 1817 by the Swedish chemist It was identified in a red deposit that had collected on the floor of a room in which sulfur, obtained as an industrial waste product from a copper mine, had been used; its similarity to tellurium had caused it to have been …

TOWARD A BETTER CLEANING AND SELECTIVITY IN ELECTROANALYSIS: TIO2-BASED SENSORS AND ENANTIOSELECTIVE MATERIALS
… of applications, like energy, catalysis and electroanalysis. One of the most valued characteristics for modern sensors are self-cleaning properties, i.e. the possibility to use the sensor more than once and to detect analytes in complex matrices, remotely without the need to clean and restore …

Heteroleptic dirhodium (II,II) complexes: synthesis, spectroscopy and applications in hydroformylation and hydroaminomethylation catalytic reactions
… influence on the metal complexes. As such, electroanalysis using cyclic voltammetry indicated variations in the metal-centred redox processes for the title complexes. The complexes obtained were used as pre-catalysts for the hydroformylation and hydroaminomethylation of olefins, an …

Green Carbon Quantum Dots Based Electrochemical Sensors for Analysis of Neurotransmitters
… in better electron transport properties. The electroanalysis of the analytes (DA, EP, and NE) at the bare and modified electrodes done with cyclic voltammetry (CV) showed that the analytes experienced better electrocatalytic oxidation at the composites modified electrodes (GCE/bCQDs/CNPs and …

Mercury Amalgam Electrodeposition on Metal Microelectrodes
… scanning electrochemical microscopy (SECM) and electroanalysis. But as applications require more and more precision, fundamental questions concerning the exact shape and constitution of the amalgam can become important for interpreting SECM experimental data. The purpose of this study is to …

Rapid separation of phenolic flavourings by liquid chromatography and nanomolar electrochemical detection at a boron-doped diamond electrode
… Initially, the whiskey is analysed using direct electroanalysis at a Nafion-modified BDD electrode. Inclusion complexation with cyclodextrins (CDs) and peak deconvolution reveals guaiacols, phenols and cresol isomers as the phenolic molecular fingerprint of whiskey. Pre-concentration with Nafion …

Rapid molecular signature analysis of pseudomonas aeruginosa by direct nanomolar detection of quorum sensing and biomarker molecules at a boron-doped diamond electrode
… using liquid-liquid extraction or SPE. The electroanalysis behavior at glassy carbon (GC) and BDD electrodes is compared for the detection of another biomolecule of P. aeruginosa specifically the synthesized ruminal biomarker “barakacin”. At pH 2.0, the detection limit (S/N = 3) on the BDD …

Development of stationary phase materials and methods for analysis of pharmaceuticals via high-performance liquid chromatography and electrochemical detection
… in the pharmaceutical industry), using direct electroanalysis at a pristine BDD electrode. The detection limit of BAK homologs with the BDD electrode was 0.4 µg/mL lower than that obtained with a glassy carbon (GC) electrode (0.68 µg/mL) in a non-aqueous medium using square wave voltammetry …
