An Assay for Aryl Radicals Using BHAS Coupling [PDF]

open access: yes, 2023
Aryl radicals are intermediates in many reactions, but determining their presence unambiguously is often challenging. As we recently reported, reaction of 2-iodo-1,3-dimethylbenzene 7 in benzene with KOtBu and a suitable organic additive, leads to a base-

Assay of the antioxidant capacity of foods using an iron(II)-catalysed lipid peroxidation model for greater nutritional relevance [PDF]

open access: yes, 2010
The formation of free radicals by the iron-catalysed Fenton reaction is a major cause of oxidative damage in the body. Here a common assay of antioxidant capacity, inhibition of the β-carotene-linoleic acid model of lipid peroxidation, has been modified ...

One-electron oxidation and reduction of glycosaminoglycan chloramides: a kinetic study. [PDF]

open access: yes, 2013
Hypochlorous acid and its acid-base counterpart, hypochlorite ions, produced under inflammatory conditions, may produce chloramides of glycosaminoglycans, these being significant components of the extracellular matrix (ECM).

Monitoring of oxidation changes of saccharides and reductones by colour indicators.

open access: yesKvasný průmysl, 2001
The article describes the colour changes of 10 indicatores by the action of radical iniciators. The majority of the indicatores has decayed on colourless products, some of them by path of colour intermediates.

Evidence of Paraoxonases 1, 2, and 3 Expression in Human Ovarian Granulosa Cells

open access: yesAntioxidants, 2021
Increasing evidence suggests that the antioxidant paraoxonase proteins, PON1, PON2, and PON3, have a role in reproduction and may be synthesized by ovarian cells.

Correlations between experimental and theoretical adiabatic ionization energies for organic compounds and rate constants for atmospheric reactions with hydroxyl radicals [PDF]

open access: yes, 2010
Adiabatic ionization energy (AIE) calculations were performed at the AM1, PM3, PM6, PDDG, HF/QZVP, and B3LYP/QZVP levels of theory on 722 atmospherically relevant organic compounds with available experimental rate constants for atmospheric reactions with

Response surface methodology to optimize the degradation of 17β-estradiol by iron nanoparticles activated peroxydisulfate

open access: yes能源环境保护, 2023
17β-estradiol (E2) is a typical endocrine disrupting compounds (EDCs) commonly found in wastewater and surface water, and is considered to cause potential environmental risks.

Isolable zwitterionic pyridinio-semiquinone ?-radicals: mild and efficient single-step access to stable radicals [PDF]

open access: yes, 2009
A rational design based on the proton-coupled electron transfer (PCET) concept allows us to structurally characterize for the first time isolable, air- and moisture-stable semiquinone radicals in a zwitterionic neutral form. The presence of an alkoxy and

Radical Pasts, Radical Futures

open access: yes, 2022
The final decades of the nineteenth century were marked by unprecedented levels of labor unrest, agitation, and organization in the United States, a period most often remembered, if at all, by way of the Great Railroad Strike of 1877 and the Homestead Steel Strike of 1892, both of which were ultimately broken by the mobilization of state, federal, or ...
