Photocatalytic Hydrogenation of Alkenes Using Water as Both the Reductant and the Proton Source

Advanced Science
Utilization of clean and low‐cost water as the reductant to enable hydrogenation of alkenes is highly attractive in green chemistry. However, this research subject is considerably challenging due to the sluggish kinetics of the water oxidation half ...

Characterization of an isobutylene epoxide hydrolase (IbcK) from the isobutylene-catabolizing bacterium Mycolicibacterium sp. ELW1

Applied and Environmental Microbiology
Isobutylene (IB) is produced on a large scale by the petrochemical industry and is metabolized by the aerobic alkene-metabolizing bacterium Mycolicibacterium sp. ELW1. The initial metabolite of IB catabolism by this bacterium is proposed to be 2-methyl-1,
