To meet various application requirements, it is important to enable an improvement of a-C structure and properties, such as hardness, adhesion, wear resistance. In this study, we used the Raman spectroscopy investigate thin films dependence on different deposition parameters. The effect nitrogen, argon, hydrogen gas flow rate was analyzed determine influence film properties. change in type, combination, had a significant D G bands spectra. addition N 2 into chamber promoted sp creation,...

The impact of different doping levels boron-doped diamond on the surface functionalization was investigated by means electrochemical reduction aryldiazonium salts. grafting efficiency 4-nitrophenyl groups increased with boron (B/C ratio from 0 to 20 000 ppm). Controlled nitrophenyldiazonium used adjust amount immobilized single-stranded DNA strands at and further hybridization yield in dependence level. grafted nitro functions were electrochemically reduced amine moieties. Subsequent a...

In this paper, for the first time, method of determination alkaloid quinoline derivation, quinine (QN), was developed. A miniatured planar electrochemical cell with a working electrode, boron-doped diamond electrode (BDDE), used. QN is easily oxidized in strongly acidic environment – 2 M HClO4 at potential Epa = +1.42 V, and an alkaline environment. +0.94 +1.18 depending on pH medium surface BDDE. Also, reduced within wide ranges background Britton–Robinson buffer (Epc −1.11 −1.51 V). This...

For its excellent electrochemical properties, boron-doped diamond (BDD) is widely used in the sensing of liquid samples. Screen-printed SP/BDD sensor platforms allow rapid detection analytes within samples with small volumes. However, drop mode (D mode), represented by a few milliliters, electroanalytical performance may differ from that observed immersion named bulk (B mode). The present study compares three-electrode both (B) and (D) modes. electrochemically formed H-terminated electrode...
