A layer-by-layer film of chitosan in a taste sensor application
(Macromolecular Bioscience, 2003-10-15) [Artigo]
Chitosan is alternated with sulfonated polystyrene (PSS) to build layer-by-layer (LBL) films that are used as sensing units in an electronic tongue. Using impedance spectroscopy as the principle method of detection, an ...
Dielectric spectroscopy on Bi3Zn2Sb3O14 ceramic: an approach based on the complex impedance
(Journal of Physics and Chemistry of Solids, 2003-12-01) [Artigo]
The dielectric properties and loss of Bi1.5ZnSb1.5O7 a poor-semiconducting ceramic were investigated by impedance spectroscopy, in the frequency range from 5 Hz to 13 MHz. Electric measurements were performed from 100 to ...
