ABSTRACT An electrochemical sensor has been developed using Patton and Reeder’s reagent which is electropolymerised on pencil graphite electrode (PR-PGE) for the selective and sensitive determination of Atenolol (ATN). The cyclic voltammetry, differential pulse voltammetry and electrochemical impedance spectra were used to check the analytical applicability of the proposed sensor for the investigation of ATN. To achieve better electrochemical response, the parameters such as pH, scan rate and electron transfer kinetics were determined. Under optimum experimental conditions, the linear calibration curve shows concentration linear range of 0.1–1.8 µM and the limit of detection 4.9 × 10−8 M. The proposed sensor shows better selectivity towards the determination of ATN in presence of organic and inorganic interfering species. The analytical performance of the PR-PGE has been studied successfully by determining ATN present in the pharmaceutical sample.

ABSTRACT Coumarin derivatives are used in a wide range of applications, such as optoelectronics, photovoltaics and dye lasers. Therefore they have attracted significant research interest. In this regard, novel coumarin dye molecules were synthesised and characterised by spectroscopic techniques. The synthesised dyes were studied for optical (linear and nonlinear), frontier molecular orbital analysis (using cyclic voltammetry and DFT calculations) and the current-voltage (I-V) studies for photosensitization behaviour on TiO2 nanoparticles. The TiO2 nanoparticles were synthesised by the sol-gel method and characterised by XRD, EDAX and SEM analysis. The results showed that the dye molecules possess good light-absorbing capability with a high molar absorption coefficient and also exhibited the good nonlinear optical (NLO) response. Moreover, the I-V characteristics suggest the efficacy of synthesised dyes for photovoltaic applications.

Abstract Micro and nano structured CuO particles were synthesized from co-precipitation method. The average crystallite size and morphology of the particles were determined using X-ray diffraction and scanning electron microscope (SEM) techniques. The effects of micro and nano sized CuO particles on the corrosion resistance of a Zn-coating were studied. The Zn-composite coatings were developed by electrodeposition using a Zn-sulfate plating bath suspended with micro/nano structured CuO particles under dc conditions. The co-deposition of secondary phase particles in the Zn-metal matrix changed the surface morphology of the metal matrix which has been analyzed by SEM photo micrographs. The Tafel and electrochemical impedance spectroscopy (EIS) corrosion tests were performed to study the corrosion resistance property of the coatings. The corrosion resistivity of Zn-metal matrix was more improvised by the co-deposition of CuO nanoparticles than by the CuO microparticles.

ABSTRACT The rapid electrochemical determination of Aceclofenac (ACF) has been employed by cyclic voltammetry (CV), differential pulse voltammetry (DPV) using developed OH-functionalised multiwalled carbon nanotube carbon paste electrode (OH-MWCNT/CPE). Modified electrode was characterised by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX), X-ray diffraction spectroscopy (XRD), electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The ACF exhibits two oxidation peaks at +0.4 V, +0.66 V and one reduction peak at +0.3 V. The active surface area of the bare carbon paste electrode (BCPE) and modified electrode have been characterised by using K3[Fe(CN)6] solution containing 0.1 M KCl. In DPV mode, variation of ACF gave the limit of detection (LOD = 3s/m) 0.246 μM over the concentration range 1.0 to 190.0 μM (R2 = 0.9994). The developed electrode has good stability, reproducibility and could be successfully validated for the detection of ACF in pharmaceutical samples and biological fluids.
