Pd-based catalysts: Influence of the second metal on their stability and oxygen reduction activity
(Pergamon-Elsevier B.V. Ltd, 2012-11-01)
PdM/C nanocatalysts (M = Ni, Fe and Co) were prepared by a polyol method varying nominal composition and reflux time. XRD studies revealed the presence of uniform strain as well as formation of an alloyed PdM phase and ...
Surface spectators and their role in relationships between activity and selectivity of the oxygen reduction reaction in acid environments
(2015-08-12)
Abstract We use the rotating ring disk (RRDE) method to study activity-selectivity relationships for the oxygen reduction reaction (ORR) on Pt(111) modified by various surface coverages of adsorbed CN<inf>ad</inf> ...
A highly sensitive amperometric sensor for oxygen based on iron(II) tetrasulfonated phthalocyanine and iron(III) tetra-(N-methyl-pyridyl)-porphyrin multilayers
(Elsevier Science BvAmsterdamHolanda, 2008)
Protective effect of nickel chloride on superoxide damage: enhancement of CuZn superoxide dismutase affinity to the oxygen free radical.
(1993-01-01)
The effect of nickel from soluble NiCl2 on Cu-Zn superoxide dismutase (SOD) activity, as well as on rate of nitro blue tetrazolium reduction, was studied in vitro since lipid peroxidation has been implicated in cell damage ...
Oxygen reduction to water operating through the Direct (or Dissociative) Route: Descriptive and fitting capabilities of polarization curves
(Pergamon-Elsevier Science Ltd, 2015-11)
The 4-e oxygen reduction reaction (orr) to water operating through the Direct Route (dissociative chemical adsorption of molecular oxygen followed by a two-step electro-reduction of adsorbed atomic oxygen) in acid media ...
Oxygen Reduction on Methanol-Tolerant Carbon-Supported PtxSy Nanoparticles Prepared by a Single-Step Low-Temperature Method
(Springer, 2019-09-01)
In direct methanol fuel cells (DMFCs), the methanol crossover from the anode to the cathode is a major cause of power density loss because of the overpotential arising due to the parasitic reaction of methanol oxidation ...
Can trifluoperazine protect mitochondria against reactive oxygen species-induced damage?
(1996-12-01)
Trifluoperazine (TFP) (35 μM) prevents mitochondrial transmembrane potential (ΔΨ) collapse and swelling induced by 10 μM Ca2+ plus oxyradicals generated from δ-aminolevulinic acid autoxidation. In contrast with EGTA, TFP ...
On the role of the surfactant aliquate (R) 336 on, the kinetics of oxygen reduction reaction and on the rate of hydrogen peroxide electro synthesis
(Elsevier Science SaLausanneSuíça, 2007)
Surface studies of lithium-oxygen redox reactions over HOPG
(Elsevier Science, 2016-04)
The O2/Li2O2 electrode reaction has been studied on low surface area HOPG electrodes in 0.1 M LiPF6 in dimethyl sulfoxide (DMSO) electrolyte. Studies were performed using electrochemical cells coupled to a XPS spectrometer ...
Is coronary sinus blood oxygen tension behavior determined by myocardial oxygen tension variation during cardiac reperfusion?
(1988-01-01)
The relationship between coronary sinus blood oxygen tension (CSPO 2) and myocardial oxygen tension (MPO 2) variations during cardiac ischemia and reperfusion was studied in anesthetized open-chest dogs. Oxygen tension was ...
