Deactivation of poly(o-aminophenol) film electrodes by storage without use in the supporting electrolyte solution and its comparison with other deactivation processes
(Elsevier, 2015-02)
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 ...
Catalysts of alkaline nitrates supported on oxides for the diesel soot combustion. Deactivation by hydro-treatment and CO2.
(Elsevier, 2013-01-20)
The deactivation of supported catalysts CsNO3 and LiNO3 for diesel soot combustion is studied in this work. The effect of hydro-treatment at high temperature and presence of CO2 in feed flow were investigated. Catalysts ...
Gas phase imidazole methylation on zeolites and HPA/SiO2: Study of acid site requirements and catalyst deactivation
(Elsevier Inc, 2013-07)
The gas-phase alkylation of imidazole with methanol was studied at 523 K on solid acids such as HPA/SiO2 and zeolites HMCM22, HBEA, NaY, ZnY and HY. The nature, density and strength of acid sites were determined by temperature ...
A review article about the deactivation of poly(o-aminophenol) film electrodes employing Impedance Spectroscopy and Surface Resistance
(Bentham Science Publishers, 2018-04)
Objective: Storage time without use (STWU) in the supporting electrolyte solution for time periods beyond 30 hours deactivates poly(o-aminophenol) (POAP) films.
Observations: Deactivated POAP films exhibit a lower ...
Deactivating Cardiac Pacemakers and Implantable Cardioverter Defibrillators in Terminally Ill Patients
(2009)
A 68-year-old patient who suffered from gastric cancer diagnosed 8 months earlier presented with multiple peritoneal and hepatic metastasis, despite several rounds of chemo- and radiotherapy. After admission to hospital, ...
Simultaneous deactivation by coke and sulfur of Pt-Re(Ge,Sn)/Al2O3 catalysts for n-hexane reforming
(Elsevier Science, 2000-04)
The simultaneous deactivation by coke and sulfur of monometallic Pt/Al2O3 and bimetallic Pt–Re(Ge, Sn)/Al2O3 catalysts was studied using n-hexane reforming as bifunctional test reaction and thiophene as poisoning molecule. ...
Deactivation of poly(o-aminophenol) film electrodes by storage without use in the supporting electrolyte solution and its comparison with other deactivation processes. A study employing EIS
(Springer, 2015-05)
Abstract The effect of storage time without use (STWU) in the supporting electrolyte solution on the charge-trans- port parameters of poly(o-aminophenol) (POAP) film electrodes was studied by electrochemical impedance ...

Effect Of The Acid-Base Properties Of Mg-Al Mixed Oxides On The Catalyst Deactivation During Aldol Condensation Reactions
(Plapiqui, 2003-12)
The effect of chemical composition of Mg-Al mixed oxides on both the acid-base properties and the deactivation process during the gas phase self-condensation of acetone was studied. The activity and selectivity for acetone ...
