Poly(o-aminophenol): a polymer employed as material of biosensors: Its deactivation. A review article
(Uptodate Research Publication, 2017-12)
Electrochemical and chemical treatments, such as, storage time without use (STWU), prolonged potential cycling (PPC), high positive potential limits (HPPL) and soaking in a ferric ion solution (SFeIS), affect the conduction ...
The effect of different electrochemical treatments on the conduction properties of an electroactive polymer: the case of poly(o-aminophenol)
(Research Trends, 2017-03)
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 ...
Surface resistance change during nickel hydroxide phase transformations
(Elsevier Science Sa, 2017-05)
Nickel hydroxide undergoes profound structural transformations under prolonged potential cycling in alkaline solutions. In this work, gold film electrodes modified with different nickel hydroxide coverages were subjected ...
Dependence on composition of electronic properties and stability of Pt-Fe/C catalysts for oxygen reduction
(Elsevier B.V., 2010-11-01)
This work presents studies of electronic characteristics and alloy stability carried out for Pt-Fe/C catalysts of different compositions (10-50% Fe, in atoms) and same particle size. The electronic properties are characterized ...
