Sequential regenerative therapy using biologic‐based regeneration and connective tissue graft wall technique for a severe infrabony defect: A case report

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Regenerative therapy based on the principles of guided tissue regeneration (GTR) is an effective approach for the treatment of periodontal infrabony defects. However, complete resolution for deep and complex defects is not always predictable.

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

open access: yesCarbon 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 ...
