These films were characterized by cyclic voltammetry, UV-visible absorption spectroscopy, Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The enzyme glucose oxidase (GOx) was entrapped into the POA film by a physical adsorption method. The resulting POA-GOx films were characterized by UV-visible absorption spectroscopy, FTIR and SEM. The amperometric response of the POA-GOx films was measured as a function of glucose concentration in phosphate buffer solution (pH 7.3). The POA-GOx films exhibited a fast amperometric response (1-5 s) and a linear response in the range of 2-20 mM glucose. The maximum current density and Michaelis-Menten constant of POA/GOx films were found to be similar to 406 mu A cm(-2) and 1.03 mM, respectively. The shelf stability, operational stability and thermal stability of these films were also investigated.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">&lt;p&gt;Foreign&lt;/p&gt;</style></custom3><custom4><style face="normal" font="default" size="100%">2.772</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Patil, Dewyani</style></author><author><style face="normal" font="default" size="100%">Patil, Pradip</style></author><author><style face="normal" font="default" size="100%">Subramanian, Vijayanand</style></author><author><style face="normal" font="default" size="100%">Joy, Pattayil Alias</style></author><author><style face="normal" font="default" size="100%">Potdar, Hari S.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Highly sensitive and fast responding CO sensor based on Co3O4 nanorods</style></title><secondary-title><style face="normal" font="default" size="100%">Talanta</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">CO sensor</style></keyword><keyword><style  face="normal" font="default" size="100%">Co3O4 nanorods</style></keyword><keyword><style  face="normal" font="default" size="100%">HRTEM</style></keyword><keyword><style  face="normal" font="default" size="100%">Semiconductor gas sensors</style></keyword><keyword><style  face="normal" font="default" size="100%">XPS</style></keyword><keyword><style  face="normal" font="default" size="100%">XRD</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">APR</style></date></pub-dates></dates><number><style face="normal" font="default" size="100%">1-2</style></number><publisher><style face="normal" font="default" size="100%">ELSEVIER SCIENCE BV</style></publisher><pub-location><style face="normal" font="default" size="100%">PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS</style></pub-location><volume><style face="normal" font="default" size="100%">81</style></volume><pages><style face="normal" font="default" size="100%">37-43</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Co3O4 nanorods (diameters similar to 6-8 nm and lengths similar to 20-30 nm) were synthesized for the first time through a simple co-precipitation/digestion method by calcination of cobalt hydroxyl carbonate in air and their CO gas sensing properties were investigated.

The alpha-FeOOH precursor was prepared through a simple and low cost wet chemical route at low temperature (40 degrees C) using FeSO4 center dot 7H(2)O and CH3COONa as starting materials. The formation of alpha-FeOOH precursor and its topotactic transformation to alpha-Fe2O3 upon calcination was confirmed by X-ray diffraction measurement (XRD). X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) analysis.

The transformation of the mixed precursor into nanostructured spinel ZnCO2O4 upon calcinations was confirmed by X-ray diffraction (XRD) measurement, thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS) and high resolution transmission electron microscopy (HRTEM). To demonstrate the potential applicability of ZnCo2O4 spinel in the fabrication of gas sensors, its LPG sensing characteristics were systematically investigated.

The asprepared CeO2 nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy( TEM) and the results indicated the formation of face centered cubic phase of CeO2 with average crystallite size of approximately 10-12 nm. Humidity sensors based on CeO2 nanoparticles exhibit high and linear response within the whole relative humidity (RH) range of 11-97% at an operating frequency of 60 Hz. The corresponding impedance changes by approximately three orders of magnitude within the entire humidity range from 11% to 97% RH. The response and recovery times are about 2-3 and 9-10 s, respectively, when RH was switched between 11% and 97%. Furthermore, the sensors also show relatively small hysteresis, excellent reproducibility, long term stability and broad range of operation (11-97% RH). The complex impedance spectra of the sensor at different RHs and the equivalent circuit were analyzed to explore the humidity-sensing mechanism. This study demonstrates that the CeO2 nanoparticles prepared by non-precipitation method can be used as the humidity-sensing material for the fabrication of humidity sensors. (C) 2014 Elsevier B. V.
