Electrochemical reduction of oxygen catalyzed by Pseudomonas aeruginosa [PDF]
, 2010 Pseudomonas aeruginosa has already been shown to catalyze oxidation processes in the anode compartment of a microbial fuel cell. The present study focuses on the reverse capacity of the bacterium, i.e. reduction catalysis. Here we show that P. aeruginosa

Influence of ocean acidification on the organic complexation of iron and copper in Northwest European shelf seas; a combined observational and model study [PDF]
, 2016 The pH of aqueous solutions is known to impact the chemical speciation of trace metals. In this study we conducted titrations of coastal seawaters with iron and copper at pH 7.91, 7.37 and 6.99 (expressed on the total pH scale).

ADSORPTIVE STRIPPING VOLTAMMETRY OF INDIUM MORIN COMPLEX
Analytical Sciences, 1991 A very sensitive adsorptive stripping voltammetric method is studied on the In-morin complex at a HMDE in 0.1 M acetate buffer (pH=3.20) solution. The effects of various analytical conditions are discussed on the reduction peak current of the absorbed complex on the surface of HMDE. Interferences by other trace metals and surfactant are also discussed.
