AB  - Microstructure and magnetic properties of nanoparticles can be tailored by optimising the synthesis procedure and changing chemical composition. In this study, a two-step procedure, i.e., coprecipitation in the presence of PEG 300 followed by microwave assisted (MW) hydrothermal synthesis, was introduced to obtain Co(x)Pe(3-x)O(4) (x = 0, 0.1 and 0.2) nanoparticles. It was found that with the increase of Co content, particle/crystallite size increased, with significant change of coercivity (H-c). The mixed samples of CoxFe3O4 (x = 0.1 and 0.2) were magnetically harder in comparison with Fe3O4. The H-c of Fe3O4 was 91 Oe, while for Co0.10Fe2.90O4 and Co(0.20)Ee(2.80) O-4, H, was 256 Oe and 1070 Oe, respectively. Saturation magnetisation (M s ) of mixed samples also increased up to 6% compared to Fe3O4. A special effort was devoted to study the effects of introducing different surfactants (PEG 300, PEG 4000 or SDS) during the synthesis procedure in order to improve morphological and microstructural properties of CoFe3O4 nanoparticles. The influence of surfactants on physical/chemical properties of nanoparticles is discussed.

AB  - In the present paper, the electrochemical behavior and the properties of two modified glassy carbon (GC) electrodes used for quantification of gallic acid in sweet wines were compared. A comparative study was conducted between titanium nitride- or wolfram carbide-doped reduced graphene oxide, labeled as TNrGO and WCrGO, respectively, modified GC electrodes, which are promising composite nanomaterials for electroanalytical applications. For the first time, WCrGO was synthesized and its electroanalytical properties compared with those of TNrGO. Results showed that the proposed materials exhibited enhanced characteristics, e.g., low limits of detection (1.1 mu M and 3.1 mu M for TNrGO and WCrGO, respectively), wide linear ranges (for TNrGO 4.5-76 mu M and for WCrGO 10-100 mu M), low adsorption, and low background current, which make them promising candidates for electrochemical sensing applications.

AB  - Colchicine (COLC) is a natural toxic product and secondary metabolite most commonly used to treat gout. In this study, its electrochemical behavior and determination was investigated by employing modification-free boron-doped diamond electrode (BDDE). Besides, its interaction with DNA was monitored using electrochemical methods. It was found that oxidation of this compound proceeds in two steps, where first sharp and well defined oxidation peak occurs at potential of around 1.19V, and second one at around 1.37V, in Britton-Robinson buffer solution at pH7.5. Wide dynamic range from 1 to 100 mu M was obtained with a detection limit (3 sigma(intercept)/slope) of a 0.26 mu M, based on the evaluation of first oxidation peak using differential pulse voltammetry. The proposed method was also found to be suitable for monitoring interaction of this drug with DNA as important segment for medical use. Concerning the validation, the analytical procedure shows excellent selectivity and sensitivity toward COLC detection and after method development it was successfully used for its quantification in pharmaceutical preparation and human serum sample, with satisfactory recovery. Obviously, this approach can be promising replacement for time-consuming and expensive separation methods.

abstract = "Colchicine (COLC) is a natural toxic product and secondary metabolite most commonly used to treat gout. In this study, its electrochemical behavior and determination was investigated by employing modification-free boron-doped diamond electrode (BDDE). Besides, its interaction with DNA was monitored using electrochemical methods. It was found that oxidation of this compound proceeds in two steps, where first sharp and well defined oxidation peak occurs at potential of around 1.19V, and second one at around 1.37V, in Britton-Robinson buffer solution at pH7.5. Wide dynamic range from 1 to 100 mu M was obtained with a detection limit (3 sigma(intercept)/slope) of a 0.26 mu M, based on the evaluation of first oxidation peak using differential pulse voltammetry. The proposed method was also found to be suitable for monitoring interaction of this drug with DNA as important segment for medical use. Concerning the validation, the analytical procedure shows excellent selectivity and sensitivity toward COLC detection and after method development it was successfully used for its quantification in pharmaceutical preparation and human serum sample, with satisfactory recovery. Obviously, this approach can be promising replacement for time-consuming and expensive separation methods.",
