Keggin heteropolyacids Mo-based as catalysts in the green and selective oxidation of diphenyl sulfide
(Elsevier, 2013-03)
Heteropolyacids are used as redox catalysts due to their bifunctional properties. Some advantages over conventional catalysts, such as selectivity, easy isolation and reuse, are worth noting. In homogeneous conditions their ...
Alumina-catalyzed epoxidation with hydrogen peroxide: Recycling experiments and activity of sol-gel alumina
(Wiley-v C H Verlag GmbhWeinheimAlemanha, 2002)
A green and reusable catalytic system based on silicopolyoxotungstovanadates incorporated in a polymeric material for the selective oxidation of sulfides to sulfones
(Elsevier Science, 2021-01)
Two vanadium-containing Keggin silicopolyoxotungsto compounds K5SiVW11O40 and K6SiV2W10O40 were synthesized and characterized. They were incorporated in a superporous hydrogel constitute by prop-2-enamide and propenoic ...
Redox status on different regions of the central nervous system of obese and lean rats treated with green tea extract
(Taylor & Francis Ltd, 2019-02-01)
Objectives: The purpose of this study was to evaluate some indicators of redox status, and inflammation on different regions of the central nervous system (CNS) of obese rats treated with green tea (GT). We hypothesized ...
A study of the temperature effect on Hantzsch reaction selectivity using Mn and Ce oxides under solvent-free conditions
(Elsevier, 2014-11-21)
In this communication, four materials (CeO2,CeO2(Cu), MnOx, and MnOx(Cu)) were prepared, characterized and tested as catalysts, in solvent-free conditions, for the multicomponent Hantzsch reactions to obtain alternatively ...
