Demixing, remixing and cellular networks in binary liquids containing colloidal particles [PDF]

, 2010
We present a confocal-microscopy study of demixing and remixing in binary liquids containing colloidal particles. First, particle-stabilized emulsions have been fabricated by nucleation and growth of droplets upon cooling from the single-fluid phase.

Isolation and Characterization of 1-Hydroxy-2,6,6-trimethyl-4-oxo-2-cyclohexene-1-acetic Acid, a Metabolite in Bacterial Transformation of Abscisic Acid

Biomolecules, 2022
We report the discovery of a new abscisic acid (ABA) metabolite, found in the course of a mass spectrometric study of ABA metabolism by the rhizosphere bacterium Rhodococcus sp. P1Y. Analogue of (+)-ABA, enriched in tritium in the cyclohexene moiety, was

Organophotoredox/Cobalt‐Catalyzed Retro‐Hydroformylation of Aldehydes

ChemistryEurope, EarlyView.
A new photoredox/cobalt retro‐hydroformylation is developed. This one‐pot two‐step process involves the in situ formation of the corresponding 1,4‐dihydropyridine as key intermediate. Under mild reaction conditions, alkenes are efficiently produced from a wide range of aliphatic α‐monosubstituted aldehydes, with high functional‐group tolerance.
