Infrared Spectra of Small Radicals for Exoplanetary Spectroscopy: OH, NH, CN and CH: The State of Current Knowledge

Molecules, 2023
In this study, we present a current state-of-the-art review of middle-to-near IR emission spectra of four simple astrophysically relevant molecular radicals—OH, NH, CN and CH.

Analysis of Protein Oxidative Modifications in Follicular Fluid from Fertile Women: Natural Versus Stimulated Cycles

Antioxidants, 2018
Oxidative stress is associated with obstetric complications during ovarian hyperstimulation in women undergoing in vitro fertilization. The follicular fluid contains high levels of proteins, which are the main targets of free radicals.

A novel profluorescent dinitroxide for imaging polypropylene degradation [PDF]

, 2008
Free-radical processes underpin the thermo-oxidative degradation of polyolefins. Thus, to extend the lifetime of these polymers, stabilizers are generally added during processing to scavenge the free radicals formed as the polymer degrades.

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

, 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).

Radical Pasts, Radical Futures

, 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 ...

On normal radicals, N-radicals, and A-radicals

Journal of Algebra, 1978
In this paper we work in the class of associative rings. Fundamental definitions and properties of radicals may be found in Divinsky [3] and Wiegandt [I 71. The concept of normal radical was introduced by Jaegermann [7] and further properties were given by Sands [12]. l’he concept of A’-radical was introduced by Sands [I I].
