Systemic characterization of the oxygen response of the wine yeast saccharomyces cerevisiae EC1118 in oenological conditions.
(2013)
Discrete oxygen additions play a critical role in alcoholic fermentation. However, few studies have quantified the fate of the dissolved oxygen and its impact on wine yeast cell physiology, under oenological conditions. ...
Inibição da mineralização de compostos nitrogenados de lixiviado de macrófita aquática: Adequação metodológica
(2008-04-01)
This study aimed to establish the adequate concentrations of nitrapyrin for the effective inhibition of oxygen demand required for the oxidation of nitrogen compounds during aerobic mineralization of leachate. The aquatic ...

Development of an electrochemical sensor for determination of dissolved oxygen by nickel-salen polymeric film modified electrode
(Elsevier B.V. Sa, 2012-12-01)
An amperometric oxygen sensor based on a polymeric nickel-salen (salen = N,N'-ethylene bis(salicylideneiminato)) film coated platinum electrode was developed. The sensor was constructed by electropolymerization of nickel-salen ...
Effect of cobalt(II) oxide and manganese(IV) oxide on sintering of tin(IV) oxide
(1996-03-01)
Additions of 0.5 to 2.0 mol% of CoO or MnO2 onto SnO, promote densification of this oxide up to 99% of theoretical density. The temperature of the maximum shrinkage rate (TM) and the relative density in the maximum ...

Spin effects in oxygen electrocatalysis: a discussion
(Elsevier Science, 2013-04)
The reduction of molecular oxygen in triplet and singlet spin states at metal electrodes is analyzed in the framework of quantum mechanical theory of charge transfer. Both outer- and inner-sphere mechanism is considered. ...
