This study developed a new type of all-solid-state ion-selective electrode based on transducing layer network single-walled carbon nanotubes. The extraordinary capacity nanotubes to promote electron transfer between heterogeneous phases made the presence electroactive polymers or any other ion-to-electron-transfer promoter unnecessary. transducer was characterized by environmental scanning microscopy and electrochemical impedance spectroscopy. stability electrical potential solid-contact...
Porous carbon materials and nanotubes were recently used as solid contacts in ion-selective electrodes (ISE), the signal transduction mechanism of these carbon-based is therefore great interest. In this work ion-to-electron studied by using electrochemical impedance spectroscopy (EIS) cyclic voltammetry (CV). Single-walled (SWCNT) are deposited on glassy (GC) disk repetitive spraying, resulting SWCNT layers with thicknesses 10, 35, 50 mum. The spectra GC/SWCNT contact aqueous electrolyte...
Surfaces made of entangled networks single-walled carbon nanotubes (SWCNTs) display a strong adsorption affinity for aromatic hydrocarbons. Adsorption these compounds onto the walls SWCNTs changes electrical characteristics SWCNT−solution interface. Using features, we have developed potentiometric sensor to detect neutral species. Specifically, can online hydrocarbons in industrial coolant water. Our chromatographic results confirm toluene nanotubes, and our impedance spectroscopy data show...
Several compositional parameters of the main hydrocarbon families are determined in naphtha. This mixture is traditionally analysed by gas chromatography (GC) but there several alternative spectroscopic methods, such as near-infrared spectroscopy combined with multivariate calibration. Spectroscopic methods have advantage that they faster and more suitable for on-line analysis. Previous studies global percentage each family: linear branched paraffins, naphthenes aromatic compounds. Here we...
In this study, we employed multivariate control techniques to detect outliers in the determination of ethylene impact polypropylene samples by near-infrared (NIR) spectroscopy and calibration partial least-squares (PLS). We also applied an algorithm which identifies those spectral variables responsible for outlier behavior that can indicate source behavior. The prediction step may be due three possible situations: errors associated with analyte concentrations have same characteristics as...
Some of the recent social and technological trends, such as telemedicine, point care chemical sensing networks, are creating a growing demand for systems that can generate information everywhere, in real time. [...]
