Adaptive Hydrogenation of Alkynes Using CO as a Molecular Trigger to Selectively Produce Alkanes or Z‐Alkenes

Angewandte Chemie, EarlyView.
One catalyst for two products: CO acts as a molecular trigger for adaptive alkyne hydrogenation using supported Pd nanoparticles. The catalyst reversibly switches between the formation of alkanes under H2 and Z‐alkenes under H2/CO for 37 structurally diverse alkynes.

Understanding the sources, function, and irreplaceable role of cobamides in organohalide-respiring bacteria

Frontiers in Microbiology
Halogenated organic compounds are persistent pollutants that pose a serious threat to human health and the safety of ecosystems. Cobamides are essential cofactors for reductive dehalogenases (RDase) in organohalide-respiring bacteria (OHRB), which ...

Remediation of Polychlorinated Biphenyls (PCBs) in Contaminated Soils and Sediment: State of Knowledge and Perspectives

Frontiers in Environmental Science, 2018
Polychlorinated biphenyls (PCBs) are one of the persistent organic pollutants (POPs) used worldwide between the 1930 and 1980s. Many PCBs can still be found in the environment such as in soils and sediments, even though their use has been heavily ...
