A scheme to model the dependence of a solute redox potential on the supporting electrolyte is proposed, and the results are compared to experimental observations and other reported theoretical models. An improved agreement with experiment is exhibited if the effect of the supporting electrolyte on the redox potential is modeled through a concentration change induced via ion pair formation with ...

The ferrocene-pyrylium dyad behaves as a selective redox and colorimetric chemodosimeter for CN(-) and HS(-) anions, exhibiting a clear perturbation in the redox potential of the ferrocene unit and in the absorption band, in the presence of these anions.

The control of molecular properties through the use of external stimuli such as pH, temperature, or change in redox potential is an attractive area of research for the regulation of various biological phenomena. Among such stimuli, light is an ideal trigger because of its potential for spatiotemporal control of cellular chemistry. The compounds that can release an active molecule upon light irr...

Alico, Robert K. (St. Bonaventure University, St. Bonaventure, N.Y.), and Francis W. Liegey. Growth of Desulfovibrio desulfuricans, under heterotrophic and anaerobic conditions. J. Bacteriol. 91:1112-1114. 1966.-Growth of Desulfovibrio desulfuricans was investigated under heterotrophic and anaerobic conditions. For initial growth to occur, it was found that the E(h) or redox potential must be a...

The growth of C. fetus fetus, C. fetus venerealis and C. fetus venerealis biotype intermedius was examined in 10 liquid media. From the data obtained, a 10% inoculum size and an oxygen level of 6% seemed imperative for consistent growth, especially for the C. fetus venerealis strain. A lowered redox potential obtained by the addition of 0, 1% cysteine-HC1 to the media was stimulatory. The mediu...

Bicyclic nitroxyl derivatives, such as 2-azaadamantane N-oxyl (AZADO) and 9-azabicyclo[3.3.1]nonane N-oxyl (ABNO), have emerged as highly effective alternatives to TEMPO-based catalysts for selective oxidation reactions (TEMPO = 2,2,6,6-tetramethyl-1-piperidine N-oxyl). Their efficacy is widely attributed to their smaller steric profile; however, electrocatalysis studies described herein show t...

Chemiluminescence (CL) that appears during oxidation of lecithin and ascorbate has been studied. A simple system consisting only of purified lecithin, which has one double bond, and ascorbate as a physiological reductant with a low redox potential, was used. The CL spectrum of lecithin contain a strong band lying in the near infrared, and three bands at 20 900 cm-1, 17 700 cm-1 and 15 800 cm-1,...

Two diacetylide-triphenylamine hole-transport materials (HTM) with varying redox potential have been applied in planar junction TiO2-[CH3NH3]PbI3-xClx solar cells leading to high power-conversion efficiencies up to 8.8%. More positive oxidation potential of the HTM gives higher VOC and lower JSC illustrating the role of matching energy levels, however both HTMs gave efficient cells despite a di...

Rapid advances in mass spectrometry have allowed for estimates of absolute concentrations across entire proteomes, permitting the interrogation of many important biological questions. Here, we focus on a quantitative aspect of human cancer cell metabolism that has been limited by a paucity of available data on the abundance of metabolic enzymes. We integrate data from recent measurements of abs...

Reduction-oxidation or redox potential is typically collected by measuring redox at a single time interval and returning to the electrode to collect subsequent intervals to generate a temporal gradient of changes in redox. Typically, intervals between sampling are on the scale of hours, days, and weeks, rather than one, five, or 20 minutes due to logistical constraints of collection. These cons...
