Continued Radicals
If a1, a2, . . . , an are nonnegative real numbers and fj(x) = paj + x, then f1o f2o· · · fn(0) is a nested radical with terms a1, . . . , an. If it exists, the limit as n ! 1 of such an expression is a continued radical. We consider the set of real numbers S(M) representable as an infinite nested …

Measurements of Atmospheric Radicals
… (PAH) and environmentally persistent free radicals (EPFR). Many PAH are photoactive and oxidize in the atmosphere into derivatives that can cause more oxidative damage than the parent compounds (oxPAH). Both PAH and EPFR are formed during the combustion process, and both have been suggested …

Continued Radicals and Cantor Sets
… to the ternary Cantor set by continued radicals. We determine properties of bridges and gaps and calculate the thickness of the Cantor set. From this we apply information from continued fractions to continued radicals to obtain new results. We also consider the measure of several Cantor …

Islamist Radicals in Latin America
Arguably, the efforts of the War on Terror in the Middle East and Southwest Asia have proven successful at eliminating bases of terrorist organizations, financial structures, and operational capabilities. Perhaps, these efforts may lead terrorists to seek out other regions to begin rebuilding their …

AMIDYL RADICALS IN LIGHT PROMOTED REACTIONS
… 1, the enantioselective addition of amidyl radicals in α position to aldehydes, (Figure 1A), the addition of N lactam radicals to nucleophiles such as heteroarenes, arenes and aldehydes (Figure 1B), the preliminary investigation of the enantioselective addition of N-acetyl radicals to …

Novel supramolecular assemblies based on sulfur-nitrogen radicals.
… the synthesis of a range of novel dithiadiazolyl radicals. The structures of these compounds are discussed. The physical properties of several compounds have been investigated using EPR spectroscopy and magnetic susceptibility studies. Chapter one begins with an overview of the chemistry of …

Strong Field Ionization Of Radicals And Reaction Intermediates
… results of adapting SFI probe for detection of radicals and their isomers. Radicals and reaction intermediates were produced using an established method flash pyrolysis. This combination allows for new insight in studying radicals and provide complementary results to the other detection methods …

Photoredox Generated Radicals In Csp2-Csp3 Bond Construction
The routine application of Csp3-hybridized nucleophiles in cross-coupling has been an ongoing pursuit in the agrochemical, pharmaceutical, and materials science industries for over 40 years. Unfortunately, despite numerous attempts to circumvent the problems associated with alkyl nucleophiles, …

Aliphatic Nitroxyl Radicals as Antifatigue Agents for Rubbers
The antifatigue activity of hindered nitroxyl radicals and their precursors have been studied. It was demonstrated that hindered alicyclic nitroxyl radicals and their precursors have weak antifatigue activities. However the trend increased in the order: amine < nitroxyl radical < hydroxylamine. The …

A study of selected water-soluble hydrazyl free radicals
… species (RNS/ROS). Many RNS/ROS are free radicals. In response, a stable water-soluble free radical able to react with other free radicals could, in theory, act as a free-radical scavenger in vivo and detect, decrease or eliminate harmful free-radical activity. Salts of water-soluble …
