Magnetization and Polarization of Coupled Nuclear Spins Ensembles at High Magnetic Fields
ChemPhysChem, EarlyView.Herein, the magnetization of spins at high magnetic fields using various theoretical approaches is analyzed. The theorem is rigorously proved that the magnetization of individual spins is equivalent to the magnetization of coupled spins within a molecule.

A Sequential Catalytic Carbonation–Hydrolysis–Diol Dehydrogenation Reaction of Epoxides
ChemPlusChem, EarlyView.A sequential/cascade carbonation–hydrolysis–diol dehydrogenation reaction of epoxides is catalyzed by <0.05 mol% of a commercially available ionic liquid and platinum on carbon, to make react CO2 and generate H2. The final catalytic system is achieved after studying the individual steps and finding common reaction conditions. These results open the way

Photooxygenation Reactions of Olefins Under Flow Conditions: An Experimental and In‐Silico Study
ChemPhotoChem, EarlyView.This study focuses on the setup and validation of the oxygenation reaction of alkenes to 1,2‐dioxetanes and hydroperoxides by a LED‐driven flow chemistry approach. An in‐silico a model was trained on reaction data that can tailor a specific chemical scope through fine‐tuning.
