Potentiometric Based Membrane Sensor for Zinc Ion
A PVC-based membrane of 12-crown-4 exhibits good response for Zn2+ in a wide concentration range (7.08 10-5-1.00 10-1 M) with a non-nernstian slope of 20.5 mv per decade of concentration of Zn2+. The response time of sensor is <10 s and the membrane can be used for more than 3 months without observing any divergence. In addition, the proposed sensor exhibits very good selectivity for Zn2+ o...
متن کاملPotentiometric Zinc Ion Sensor Based on Honeycomb-Like NiO Nanostructures
In this study honeycomb-like NiO nanostructures were grown on nickel foam by a simple hydrothermal growth method. The NiO nanostructures were characterized by field emission electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD) techniques. The characterized NiO nanostructures were uniform, dense and polycrystalline in the crystal phase...
متن کاملOxygen surface exchange kinetics of erbia-stabilized bismuth oxide
The surface oxygen exchange kinetics of bismuth oxide stabilized with 25 mol% erbia (BE25) has been studied in the temperature and pO2 ranges 773–1,023 K and 0.1– 0.95 atm, respectively, using pulse-response O–O isotope exchange measurements. The results indicate that BE25 exhibits a comparatively high exchange rate, which is rate determined by the dissociative adsorption of oxygen. Defect chem...
متن کاملBismuth Oxide: A New Lithium-Ion Battery Anode.
Bismuth oxide directly grown on nickel foam (p-Bi2O3/Ni) was prepared by a facile polymer-assisted solution approach and was used directly as a lithium-ion battery anode for the first time. The Bi2O3 particles were covered with thin carbon layers, forming network-like sheets on the surface of the Ni foam. The binder-free p-Bi2O3/Ni shows superior electrochemical properties with a capacity of 66...
متن کاملMechanochemical Synthesis and Characterisation of Bismuth-Niobium Oxide Ion Conductors
Bismuth niobate solid solutions, BixNbOδ (2.5 ≤ x ≤ 6), have been prepared using a mechanochemical method. The solid solutions were also prepared using a solidstate conventional method for comparison purposes. Bi3NbO7 was successfully obtained via a mechanochemical method at a lower synthesis temperature (milled at 1000 rpm for one hour followed by heating at 700C for 24 h) than the conventiona...
