a new al(iii) selective membrane based on 5-bromo(salicylidene-2-amino thiophenol) as a neutral carrier in a poly(vinyl chloride) (pvc) matrix is coated on platinum wire to determine trace amounts of al(iii) ion in various samples. the sensor exhibits a good response for al(iii) ion over a wide concentration range of 5.20 × 10-7 to 1.00 × 10-2 m  with nernstian slope of 19.64 ± 0.15 mv decade-1...

A new approach on the synthesis of Si anodes for Li-ion batteries is reported, combining advantages of both nanoparticulated and continuous Si films. A multilayered configuration prototype is proposed, comprising amorphous Si arranged in nanostructured, mechanically heterogeneous films, interspersed with Ta nanoparticle scaffolds. Particular structural features such as increased surface roughne...

sol-gel and polymeric membrane electrodes, based on thiacalix[4]arene as a neutral carrier, weresuccessfully developed for the detection of vo2+ in aqueous solutions. the sol-gel and pvcmembrane electrodes exhibited linear response with nernstian slopes of 29.3 and 28.4 mv perdecade, respectively, within the vanadyl ion concentration ranges from 1.0 × 10-6 to 1.0 × 10-1mol dm-3 and from 1.0 × 1...

Where E0 is the standard electrode potential, R is the universal gas constant, T is the absolute temperature, z is the number of moles of electrons transferred in the cell reaction or halfreaction, F is the Faraday-constant, and cox and cred are the concentrations of the oxidized and reduced forms of the component. The potential of the hydrogen electrode is declared to be 0.000 V at all tempera...

In this work the ion-selective response of an electrolyte-gated carbon-nanotube field-effect transistor (CNT-FET) towards K(+), Ca(2+) and Cl(-) in the biologically relevant concentration range from 10(-1) M to 10(-6) M is demonstrated. The ion-selective response is achieved by modifying the gate-electrode of an electrolyte-gated CNT-FET with ion-selective membranes, which are selective towards...
