Reductants in Gold Nanoparticle Synthesis Using Gas–Liquid Interfacial Discharge Plasmas
Applied Physics Express, 2012Co-Authors: Qiang Chen, Toshiro Kaneko, Rikizo HatakeyamaAbstract:We report the origins and types of reductant in the discharge-plasma-induced gold nanoparticle (AuNP) synthesis. The formation of AuNPs by contacting Au(III)-containing solution with plasma is ascribed to two types of reductant generated by plasma-solution interaction, i.e., the short-lived Reductants including free, secondary, and hydrated electrons, hydrogen as well as ultraviolet light, and a long-lived reductant, hydrogen peroxide which has normally been regarded as an oxidant in plasma-induced metal nanoparticle synthesis. We expect that the elucidation of the Reductants involved will be beneficial for further understanding and control of plasma-induced metal nanoparticle synthesis.

the reduction of membrane bound dopamine β monooxygenase in resealed chromaffin granule ghosts is intragranular ascorbic acid a mediator for extragranular reducing equivalents
Journal of Biological Chemistry, 1995Co-Authors: Kandatege Wimalasena, Shyamali D WimalasenaAbstract:Abstract The role of internal and external Reductants in the dopamine β-monooxygenase (DβM)-catalyzed conversion of dopamine to norepinephrine has been investigated in resealed chromaffin granule ghosts. The rate of norepinephrine production was not affected by the exclusion of internal ascorbate. The omission of ascorbate from the external medium drastically reduced the norepinephrine production without affecting the net rate of dopamine uptake. In the presence of the external reductant, the internal ascorbate levels were constant throughout the incubation period. The rate of norepinephrine production was not affected when ghosts were resealed to contain the DβM reduction site inhibitor, imino-D-glucoascorbate. Ghosts incubated with external imino-D-glucoascorbate reduced the norepinephrine production. The weak DβM reductant, 6-amino-L-ascorbic acid, was found to be a good external reductant for granule ghosts. The outcome of the above experiments was not altered when dopamine was replaced with the reductively inactive DβM substrate, tyramine. These results and the known topology of membrane-bound DβM disfavor the direct reduction of the enzyme by the external reductant. Our observations are consistent with the hypothesis that external ascorbate is the sole source of reducing equivalents for DβM monooxygenation and that internal soluble ascorbate (or dopamine) may not directly reduce or mediate the reduction of membrane-bound DβM in resealed granule ghosts.

On Reductants in the framework of multi-adjoint logic programming
Fuzzy Sets and Systems, 2017Co-Authors: Pascual Julin-iranzo, Jess Medina, Manuel Ojeda-aciegoAbstract:Reductants are a special kind of fuzzy rules which constitute an essential theoretical tool for proving correctness properties. As it has been reported, when interpreted on a partially ordered structure, a multi-adjoint logic program has to include all its Reductants in order to preserve the approximate completeness property. After a short survey of the different notions of reductant that have been developed for multi-adjoint logic programs, we introduce a new and more adequate notion of reductant in the multi-adjoint framework. We study some of its properties and its relationships with other notions of Reductants, and provide an algorithm for computing all the Reductants associated with a multi-adjoint logic program.

JELIA - Revisiting Reductants in the Multi-adjoint Logic Programming Framework
Logics in Artificial Intelligence, 2014Co-Authors: Pascual Julián-iranzo, Jesús Medina, Manuel Ojeda-aciegoAbstract:In this work, after revisiting the different notions of reductant arisen in the framework of multi-adjoint logic programming and akin frameworks, we introduce a new, more adequate, notion of reductant in the context of multi-adjoint logic programs. We study some of its properties and its relationships with other notions of Reductants.
