Sustainable Germanium Recovery From Germanium Dioxide via Halogen‐Free Chemical Vapor Transport
Chemistry – A European Journal, EarlyView.Recovery of the critical element Ge from GeO2 and SiO2/GeO2 mixtures was investigated based on an endothermic chemical vapor transport via GeO, formed with natural gas or a hydrogen(10%)‑argon(90%) mixture and water vapor. (This picture was partly created with AI, engine: Adobe Firefly).

Self‐Immolative Poly(Benzyl Ether)s: Design Principles and Controlled Depolymerization
Chemistry – A European Journal, EarlyView.Unzipping to Sustainability: This Concept article explores the thermodynamic design of quinone‐methide (QM)‐based poly(benzyl ether)s (PBEs). It explains how a low ceiling temperature (Tc), QM stability, and an entropic gain drive rapid depolymerization (“unzipping”) of PBEs into monomers.
