RISElectrooxidation of ethanol using polypyrrole/platinum nanocomposite
The world’s demand for energy has increased dramatically over the last few decades, and will continue to do so. Therefore, it is urgent to find alternative
energy sources and perhaps unconventional way of energy ...
Complexation of 4′-nitrobenzo-15-crown-5 with Li+, Na +, K+, and NH4+ cations in acetonitrile-methanol binary solutions
The complexation processes between Li+, Na+, K + and NH4+ cations with macrocyclic ligand, 4′-nitrobenzo-15C5, were studied in acetonitrile-methanol (AN-MeOH) binary mixtures at different temperatures using conductometric ...
Competitive Bulk Liquid MembraneTransport of Transition and Post Transition Metal Cations Using (2, 3-Diphenylquinoxaline)-4،4
A series of competitive metal ion transport experiments have been performed, each involved transport from an aqueous source phase across an organic membrane phase into an aqueous receiving phase. The source phase contained ...
Discussion on the Complexing Ability of 4 -nitrobenzo-15-Crown-5 with K+Na+ NH4+ Cations in Acetonitrile- Methanol Binary Media
The complexation processes between K+, Na+ and NH4+ cations with macrocyclic ligand, 4\\\\\\'-nitrobenzo-15C5, were studied in acetonitrile-methanol (AN-MEOH) binary mixtures at different temperatures using conductometric ...
High catalytic performance of Pt nanoparticles via support of conducting polymer for electrooxidation of methanol at carbon ceramic electrode
Carbon ceramic electrode (CCE), a new electrode substrate, was prepared by sol–gel procedure and used for the electropolymerization of aniline and dispersion of platinum nanoparticles into the resulting polyaniline (PANI) ...
Thermodynamic behavior of complexation process between benzo-15-crown-5 with Li+, Na+, K+, and NH4+cations in acetonitrile–methanol binary media
The stability constants of 1:1 (M:L) complexes of benzo-15-crown-5 (B15C5) with Li+, Na+, K+ and NH4+ cations, the Gibbs standard free energies (DGºc), the standard enthalpy changes (DHºc) and standard entropy changes ...
Electrochemical preparation of effective and low cost catalyst for electrooxidation of ethanol
A nanocatalyst coating was prepared at surface of a glassy carbon electrode by electropolymerization of pyrrole by cycling the electrode potential between −0.8 and 0.8 V (vs. Ag/AgCl). Then, polypyrrole film was ...
Alizarin red S loaded polypyrrole modified glassy carbon electrode for the determination of silver species by anodic stripping differential pulse voltammetry
Extraction of trace analyses by complexion is an efficient technique for voltammetric determination at chemically modified electrodes. Many of the selective ligands used for non-electroanalytical determinations can be ...
Effect of magnetic field on property of a non-aqueous solvent upon complex formation between kryptofix 22DD with yttrium (III) cation
Abstract To understand the effect of a magnetized solvent upon complexation processes between the metal ions and the ligands, we studied the complexation reaction between Y?3 cation with the kryptofix 22DD, in nonmagnetized ...
New polypyrrole–carbon nanotubes–silicon dioxide solid-phase microextraction fiber for the preconcentration and determination of benzene, toluene, ethylbenzene, and o-xylene using gas liquid chromatography
For the first time, a polypyrrole–carbon nanotubes–silicon dioxide composite film coated on a
steel wire was prepared by an electrochemicalmethod. Scanning electron microscopy images
showed that this composite ...
