Size-Controlled Pd Nanoparticles in 2-Butyne-1,4-diol Hydrogenation: Support Effect and Kinetics Study

Lioubov Kiwi, Fernando Cardenas Lizana, Charline Berguerand

Structured catalyst has been developed for C–C triple bond three-phase hydrogenation. The sintered metal fiber (SMF) coated by different oxides served as support for monodispersed Pd nanoparticles (6.4 ± 0.5 nm). The effect of acid–base properties and redu ...

Functional characterization of a new tetrachloroethene reductive dehalogenase of Sulfurospirillum spp. identified in mixed cultures

Christof Holliger, Julien Maillard, Géraldine Florence Buttet

Recent analysis of a set of reductive dehalogenases revealed that sequence similarity and substrate specificity are not correlated, making functional prediction from sequences difficult (1). To this respect, several enrichment cultures were investigated fo ...
