Spin—Lattice Relaxation in Organo—Sulfur Radicals

Semi-radicals of Sub modules in Modules

Abstract: Let be a commutative ring and be a unitary module. We define a semiprime submodule of a module and consider various properties of it. Also we define semi-radical of a submodule of a module and give a number of its properties. We define modules which satisfy the semi-radical formula and present the existence of such a module.  

Improved Biodesulfurization of Persistent Organosulfur Compounds

Quantification of Radicals Generated in a Sonicator

The hydroxyl radical (OH•) is a powerful oxidant produced as a consequence of cavitation in water. It can react nonspecifically in breaking down persistent organic pollutants in water into their mineral form. It can also recombine to form hydrogen peroxide which is very useful in water treatment. In this study, terephthalic acid (TA) and potassium iodide dosimetry were used to quantify and inve...

SEMI-RADICALS OF SUB MODULES IN MODULES

Let  be a commutative ring and  be a unitary  module. We define a semi prime sub module of a module and consider various properties of it. Also we define semi-radical of a sub module of a module and give a number of its properties. We define modules which satisfy the semi-radical formula and present the existence of such a module.

Scavenging free radicals to preserve enhancement and extend relaxation times in NMR using dynamic nuclear polarization.

Dynamic nuclear polarization (DNP) can enhance the nuclear polarization, that is the difference between the populations of the Zeeman levels jai and jbi of spin I= 1/2, by up to four orders of magnitude with respect to their Boltzmann distribution at room temperature. This enhancement arises from thermal mixing, which is brought about by microwave saturation of the EPR transitions of stable rad...
