The Effect of Water Management and Cell Compression in Bipolar Membrane CO2 Electrolysis to CO

Carbon Energy, EarlyView.
In‐operando neutron imaging uncovers water management challenges in bipolar membrane CO2 electrolysis: Internal water generation floods the cathode, while compression dictates membrane and gas diffusion electrode integrity. Strategic adjustments are applied in this work: dry gas feed and mechanical support of the gas diffusion electrode enable stable ...

Synthesis, Physicochemical Characteristics, Self‐Assembly and Encapsulation Ability of per‐Ethylene‐Glycol‐Functionalized Resorcin[4]Arenes and Their Molecular Capsules: On the Road to Liquid Capsules

Chemistry – A European Journal, EarlyView.
Per‐ethylene‐glycol (EG)‐functionalized resorcin[4]arenes containing 12, 16, and 20 EG groups namely compounds 1d, 1e, and 1f, respectively, were prepared and found to self‐assemble, in organic solvents, into hexameric capsules. These capsules are more dynamic than the ones prepared based on alkyl substituted resorcin[4]arenes.
