The experimental arrangement in this investigation is one in which poly(o-aminophenol) (POAP) films were supported on thin gold films. Freshly prepared POAP film electrodes were firstly deactivated by interaction with a ferric cation solution and then, they were reactivated by treatment with an alkaline solution. Cyclic Voltammetry (CV) and Surface Resistance (SR) measurements were performed to...

The aim of this work was to demonstrate that interaction of ferric cations with poly(o-aminophenol) (POAP) films causes their deactivation. Spectroelectrochemical measurements and rotating disk electrode voltammetry (RDEV) were employed on both freshly prepared and deactivated POAP films. It was observed a reduction (deactivation) of the redox activity of POAP after its treatment with ferric ca...

An amperometric glucose biosensor is developed that is based on immobilization of glucose oxidase (GOD) in a composite film of poly(o-aminophenol) (POAP) and carbon nanotubes (CNT), which are electrochemically co-polymerized at a gold (Au) electrode. Because of the high surface per volume ratio and excellent electrical conductivity of CNT, the biosensor based on an Au/POAP/CNT/GOD electrode has...

Modern wireless networks are offering a wide range of applications that require the efficient integration of multimedia and traditional data traffic along with QoS provision. The IEEE 802.11e workgroup has standardized a new QoS enhanced access scheme for wireless LANs, namely Hybrid Control Function (HCF). HCF consists of the Enhanced Distributed Channel Access (EDCA) and the Hybrid Control Ch...

In situ electropolymerization as a facile synthetic procedure has been used to obtain highly active compositesof ionic liquid functionalized graphene oxide(FGO)and poly ortho aminophenol (POAP). Surface and electrochemical analysis have been used for characterisation of FGO-POAP composite film. Nickel was accumulated by complex formation between Ni (II) in solution and amines sites in the polym...

Postoperative acute pancreatitis (POAP) emerges as a distinct pancreas-specific complication increasing both the risk and burden of POPF after pancreatoduodenectomy. Among various factors, pancreas stump (PS) hypoperfusion might play role in POAP occurrence but has never been investigated. The current study aimed at evaluating feasibility intraoperative fluorescence angiography (IOFA) PS using ...
