An impedance study about the effect of pH on the electron transport rate at poly(o-aminophenol) film electrodes
(Bentham Science Publishers, 2014-06)
Impedance measurements on poly(o-aminophenol) (POAP) film electrodes in solutions of different pH were carried out. Impedance spectra were interpreted in terms of the modified electron hopping model described in F.J. ...
The Role Of Rotational Mechanisms In Electron Swarm Parameters At Low Reduced Electric Field In N-2, O-2 And H-2
(IOP PUBLISHING LTDBRISTOL, 2015)
Nickel hydroxide films in contact with an electroactive solution. A study employing electrochemical impedance measurements
(AIRCC Publishing Corporation, 2016-02)
The deactivation of nickel hydroxide films after prolonged storage times without use was studied. This study was carried out in the context of the Rotating Disc Electrode Voltammetry (RDEV) and<br />Electrochemical Impedance ...
A Study of the Charge Transport Process at Nickel Hydroxide-Gold Modified Electrodes employing Rotating Disc Electrode Voltammetry and Ac Impedance Measurements
(Scienctific Online, 2014-02)
The aim of the present work was study how the charge-transport process of a nickel hydroxide film electrochemically synthesized on a gold substrate is modified when the electrode is stored without use for long time. It was ...
Influence of Edible Coating on the Drying and Quality of Papaya (Carica papaya)
The edible coating applied to food pieces prior to hot air drying is a technology that can improve the nutritional and sensory qualities of dehydrated products. The effects of the pectin coating technique on the drying ...
Comparison Results for Reflected Jump-diffusions in the Orthant with Variable Reflection Directions and Stability Applications
(UNIV WASHINGTON, DEPT MATHEMATICS, 2008-10-30)
We consider reflected jump-diffusions in the orthant Rn + with time- and state-dependent drift, diffusion and jump-amplitude coefficients. Directions of reflection upon hitting boundary faces are also allow to depend ...
Effect of Hygrothermal History on Water and Mechanical Properties of Glass/Vinylester Composites
(Sage Publications Ltd, 2006-01-01)
The effects of hygrothermal aging on the mechanical and viscoelastic properties of vinylester (VE)/unidirectional glass-fiber composites are reported. The studies are done by means of a dynamometer (INSTRON) and a dynamic ...
Deactivation of poly(o-aminophenol) film electrodes by storage without use in the supporting electrolyte solution and its comparison with other deactivation processes
The effect of storage time without use (STWU) in the supporting electrolyte solution on the conducting properties of poly(o-aminophenol) (POAP) film electrodes was studied. Cyclic voltammetry (CV), rotating disc electrode ...
Diffusion of plasticizer in a solid propellant based on hydroxyl-terminated polybutadiene
