Nitrate elimination by denitrification in hardwood forest soils of the Upper Rhine floodplain – correlation with redox potential and organic matter [PDF]

open access: yes, 2002
Denitrification in floodplains is a major issue for river- and groundwater quality. In the Upper Rhine valley, floodplain forests are about to be restored to serve as flood retention areas (polders).

nfluence of reducing and oxidizing compounds and of the redox potential of the medium on the biomass of Scenedesmus quadricauda (Turp.) Breb.

open access: yesActa Societatis Botanicorum Poloniae, 2014
The influence was investigated of several concentrations of the reducing agents: cysteine, glutathione, ascorbic acid, pyracatechol and of the oxidizing agents: KMnO4, K4Cr2O7 and H2O2 on the total dry weight increment and that of protein with reference ...

Characterization of Fe implanted yttria-stabilized zirconia by cyclic voltammetry [PDF]

open access: yes, 1992
The technique of cyclic voltammetry has been applied to study reduction and oxidation phenomena which are observed at low oxygen partial pressures during steady state current-overpotential measurements of the Au, O2(g)/Fe implanted yttria-stabilized ...

The relationship between redox enzyme activity and electrochemical potential—cellular and mechanistic implications from protein film electrochemistry [PDF]

open access: yes, 2011
In protein film electrochemistry a redox protein of interest is studied as an electroactive film adsorbed on an electrode surface. For redox enzymes this configuration allows quantification of the relationship between catalytic activity and ...

Absorção de bário por plantas de arroz (Oryza sativa L.) e mobilidade em solo tratado com baritina sob diferentes condições de potencial redox

open access: yesQuímica Nova, 2012
Two parallel tests were carried out to evaluate barium solubility in soils treated with barite under reducing conditions: one in leaching columns and another with potted plants cultivated with rice.

The thermodynamic landscape of carbon redox biochemistry [PDF]

open access: yes, 2018
Redox biochemistry plays a key role in the transduction of chemical energy in all living systems. Observed redox reactions in metabolic networks represent only a minuscule fraction of the space of all possible redox reactions.

Extracellular cysteine in connexins: Role as redox sensors [PDF]

open access: yes, 2016
Indexación: Scopus.Connexin-based channels comprise hemichannels and gap junction channels. The opening of hemichannels allow for the flux of ions and molecules from the extracellular space into the cell and vice versa.

Spectroelectrochemical Elucidation of the Kinetics of Two Closely Spaced Electron Transfers [PDF]

open access: yes, 2012
The use of spectroelectrochemistry to facilitate the analysis of an EE mechanism was reported in this work. Using a set of spectra as a function of potential, the spectra of all three oxidation states were determined using evolving window factor analysis.

Biophysical Features of Bacillithiol, the Glutathione Surrogate of Bacillus subtilis and other Firmicutes [PDF]

open access: yes, 2013
Bacillithiol (BSH) is the major low-molecular-weight (LMW) thiol in many low-G+C Gram-positive bacteria (Firmicutes). Evidence now emerging suggests that BSH functions as an important LMW thiol in redox regulation and xenobiotic detoxification, analogous

Mobilidade de bário em solo tratado com sulfato de bário sob condição de oxidação e redução

open access: yesQuímica Nova, 2011
In order to evaluate possible solubility of BaSO4 in soils under reducing conditions, column leaching assay was settled down, where the soil received three doses of BaSO4 (100, 300 and 3000 mg kg-1) at two humidities.
