Sentence examples for radical compound from inspiring English sources

For comparison purposes, the rate constant for the direct electrode reduction of the HRP oxyferryl π-cation radical Compound I was determined in MB-free SWNTs.

DPPH is a free radical compound and has been widely used to test the free radical-scavenging ability of various samples.

The proposed mechanism for O2 formation (Scheme 1) involves initial transfer of an oxygen atom from ClO2– to the ferric heme to make an FeIV=O porphyrin (Por) π-cation radical (Compound I).

Fullerenol may also function as an antioxidant by the donation of the hydrogen atom, abstracted from the hydroxyl group, to the particular radical compound (DPPH and OH), which was confirmed by EPR detection of C60(OH)23O, a fullerenol radical.

This facilitates the scission of the di-oxygen bond to form the ferryl iron and porphyrin cation radical (Compound I), followed by a rapid migration and partial decay of the radical to form compound II.

This intermediate was trapped and characterized using various spectroscopic methods, such as electron nuclear double resonance (ENDOR) and resonance Raman spectroscopy at low temperature.[ 10] A final proton delivery step in the catalytic cycle converts Cpd 0 into the active species, namely an iron(IV oxo heme cation radical (Compound I, Cpd I).

Such errors can be attributed to salt forms, isotopic elements, radical compounds and conversion issues.

To confirm this hypothesis, surface-coated polymers containing nitroxide radical compounds (nitroxide radical-containing polymers (NRP)) were designed and developed.

Some nitroxyl radical compounds which have different structures have been prepared and their electrochemical behavior and spectroscopic properties have been studied.

The electrochemical measurements in aprotic electrolyte revealed that most nitroxyl radical compounds show reversible redox behavior similar to that of TEMPO independent of their structures in the range of −0.15 0.20 V versus Ag/Ag+ (3.69 4.04 V versus Li/Li+).

It should be noted that antioxidant compounds, like ascorbate and α-tocopherol, all have the inherent capacity to act as prooxidants because they easily form radical compounds, with their cellular effects thereby being a matter of concentration and the microenvironment within which they act.
