Outstanding performance of rehydrated Mg-Al hydrotalcites as heterogeneous methanolysis catalysts for the synthesis of biodiesel
There is still a need for active, selective and stable heterogeneous catalysts for the synthesis of biodiesel. In this work, magnesium-aluminium hydrotalcites with Mg/Al molar ratios within the 1.5–5 range were synthesized ... -
Preparation of Al/Fe-pillared clays: effect of the starting mineral
Four natural clays were modified with mixed polyoxocations of Al/Fe for evaluating the effect of the physicochemical properties of the starting materials (chemical composition, abundance of expandable clay phases, cationic ... -
Rosa canina extracts have antiproliferative and antioxidant effects on caco-2 human colon cancer
The in vitro antiproliferative and antioxidant effects of different fractions of Rosa canina hips on human colon cancer cell lines (Caco-2) was studied. The compounds tested were total extract (fraction 1), vitamin C ... -
Rutas y retos para la valorización de biogás
Las tecnologías de digestión anaerobia para procesar corrientes residuales (fracción orgánica de residuos de vertedero, lodos de estaciones depuradoras de aguas residuales, purines, etc.) han originado un incremento de ... -
Synthesis and molecular structures of palladium(II) metalated 2-phenylpyridine complexes [PdCl(pyC6H4)L] containing amino- or acetylamino-pyridine co-ligands
A number of cyclometalated palladium(II) complexes [PdCl(pyC6H4)(L)] containing amino-pyridine or acetylamino-pyridine co-ligands (L) have been prepared from the reaction of [Pd(pyC6H4)(μ-Cl)]2 with two equivalents of these ... -
Synthesis of zeolite a from metakaolin and its application in the adsorption of cationic dyes
The present work reports the synthesis of zeolites from two metakaolins, one derived from the white kaolin and the other derived from the red kaolin, found in a deposit in the city of São Simão (Brazil). The metakaolins ... -
Therapeutic applications of rose hips from different rosa species
Rosa species, rose hips, are widespread wild plants that have been traditionally used as medicinal compounds for the treatment of a wide variety of diseases. The therapeutic potential of these plants is based on its ... -
α-Hydroxy ketones as masked ester donors in Brønsted base catalyzed conjugate additions to nitroalkenes
The catalyst-controlled enantioselective direct addition reaction of enolizable esters and related carboxylic acid derivatives to p electrophiles remains a difficult synthetic transformation. In this study, the suitability ...
