Journal ArticleDOI
Novel strategic lipase-catalyzed asymmetrization of 1,3-propanediacetate in supercritical carbon dioxide
TL;DR: In this paper, a conformational changing of lipase at the active site due to a transformation of the amino group of lysine into carbamic acid was found to increase the enantioselectivity.
Journal ArticleDOI
Ruthenium and rhodium nanoparticles as catalytic precursors in supercritical carbon dioxide
Martha V. Escárcega-Bobadilla,Martha V. Escárcega-Bobadilla,Clara Tortosa,Emmanuelle Teuma,Christian Pradel,Aránzazu Orejón,Montserrat Gómez,Anna M. Masdeu-Bultó +7 more
TL;DR: In this article, the synthesis of Ru and rhodium nanoparticles in the presence of phosphine ligands containing fluorinated groups has been studied, starting from well-defined organometallic compounds.
Journal ArticleDOI
Plant products for pharmacology: application of enzymes in their transformations.
Marie Zarevúcka,Zdeněk Wimmer +1 more
TL;DR: Attention is focused on lipases, efficient and convenient biocatalysts for the enantio- and regioselective formation / hydrolysis of ester bond in a wide variety of both natural and unnatural substrates, including plant products, eg.
Journal ArticleDOI
Modeling Solvation in Supercritical CO2.
TL;DR: The theoretical work that has been relevant to developments in technologies based on supercritical carbon dioxide is surveyed and, by presenting some crucial open questions, the possible routes to achieving further progress based on the interplay between theory and experiments is discussed.
Journal ArticleDOI
Fe3O4@SiO2·HM·SO3H as a recyclable heterogeneous nanocatalyst for the microwave-promoted synthesis of 2,4,5-trisubstituted imidazoles under solvent free conditions
TL;DR: In this article, a simple, highly versatile and efficient synthesis of 2,4,5-trisubstituted imidazoles is achieved through a three component one pot reaction of benzil, benzaldehyde and NH4OAc.

Structures of metal sites of oxidized bovine heart cytochrome c oxidase at 2.8 A
Tomitake Tsukihara,Hiroshi Aoyama,Eiki Yamashita,Takashi Tomizaki,Hiroshi Yamaguchi,Kyoko Shinzawa-Itoh,Ryosuke Nakashima,Rieko Yaono,Shinya Yoshikawa +8 more
TL;DR: The high resolution three-dimensional x-ray structure of the metal sites of bovine heart cytochrome c oxidase is reported, suggesting a dinuclear copper center with an unexpected structure similar to a [2Fe-2S]-type iron-sulfur center.
Journal ArticleDOI
Homogeneous Hydrogenation of Carbon Dioxide
TL;DR: In this article, the simplest and most studied reactions of CO{sub 2} are the catalytic reactions with H{sub 1} in the presence or absence of other reactive species.
