Chemically modified electrodes (CMEs) based on polymeric films of E-5-((5-isopropyl-3,8-dimethylazulen-1-yl) diazenyl)-1H-tetrazole (L) deposited the surface glassy carbon electrode have been used for recognition heavy metal (Me) ions. The electrochemical study L was done by three methods: differential pulse voltammetry (DPV), cyclic (CV), and rotating disk (RDE). CV, DPV, RDE studies were perf...

We report on the sensing of a hazardous pesticide alphacypermethrin (ACM) using electrochemical technique through nanocomposite film modified electrode. The comprising octadecylamine, chitosan, polyvinyl alcohol-silver nanowires and haemoglobin, shortly (OCPAH), was prepared by Langmuir–Blodgett (LB) deposition various substrates electrodes. composite LB characterised UV-visible spectroscopy sc...

The synthesis, spectroscopic and electrochemical properties of the following octa-benzothiazole substituted metal-free (4), cobalt(II) (5) zinc (II) (6) phthalocyanines are reported for first time. novel have been characterized by FT-IR, NMR spectroscopy, electronic spectroscopy mass spectroscopy. Voltammetric analysis benzothiazole group were determined cyclic (CV) square wave voltammetry (SWV...

: In this work, molybdenum disulfide (MoS2) nanorods (NRs) were prepared by a simple hydrothermal method. A sensitive electrochemical glucose biosensor was developed based on the immobilization of oxidase (GOx) MoS2 NRs modified glassy carbon electrode (GCE). The SnO2 characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), and energy dispersive spectroscop...

In this study, we report the detection of dissolve oxygen (DO) by using a blend Ruthenium oxide and polyaniline (PANI) coated on platinum electrodes. Optical properties PANI were characterized Ultraviolet - Visible (UV-Vis) Fourier-transform infrared (FTIR) spectroscopy. order to study sensitivity thin films PANI: blend, cyclic voltammetry (CV) measurements was performed with electrodes oxide. ...

The classical 1D continuum model of oxygen exchange in a porous mixed conductor (bulk path) is presented terms Linear Sweep Voltammetry (LSV) and Cyclic (CV). We show that, from formal point view, it corresponds to an insertion, diffusion chemical reaction mechanism. Some general rules for LSV/CV curves are established. Using dimensionless description, we evidence eight different limiting behav...

Six star-shaped oligomers containing triphenylamine (D1-D3) and benzene unit (D4-D6) as cores have been synthesized by Wittig condensation or Heck coupling reaction using aromatic aldehydes and triphenylphosphonium salts or aromatic halogenated compounds with vinyl triphenylamine. All oligomers have well-defined molecular structure and high purity. Characterization of the oligomers was made by ...

Cobalt(II) and manganese(III) phthalocyanines bearing peripherally and non-peripherally tetra substituted {(2E)-3-[4-(dimethylamino)phenyl]prop-2-enoyl}phenoxy groups were synthesized by cyclotetramerization of the phthalonitrile derivatives and their electrochemical properties were examined using CV and SWV techniques for the first time. The novel compounds were characterized by using IR, (1)H...

Herein, two title compounds, N-benzoyl-N′-(4′-cyanophenyl)thiourea (1) and N-(4-nitrobenzoyl)-N′-(4′-cyanophenyl)thiourea (2) were synthesized in a high yield, via different applications of aroyl isocyanate 4-aminobenzonitrile. The structure the prepared compounds was characterized by elemental analysis FT-IR, 1H, 13C-NMR spectroscopic methods. crystal compound 1 determined an X-ray single-crys...

Determining the relative energies of transport states in organic semiconductors is critical to understanding properties electronic devices and designing device stacks. Futhermore, defect are also highly important can greatly impact material performance. Recently, energy-resolved electrochemical impedance spectroscopy (ER-EIS) developed probe both ionization energy (IE) electron affinity (EA) as...
