Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

The potential of far-red light-acclimating cyanobacteria to support sustainable outposts on Mars

open access: yesFrontiers in Astronomy and Space Sciences
BackgroundLong-duration crewed missions on the Moon and Mars rely on support technologies based on locally available resources. Rock-weathering cyanobacteria are key enablers to transform minerals, carbon dioxide and urine (from crew waste) into biomass ...

Resolving the Structural Duality of Graphene Grain Boundaries

open access: yesAdvanced Materials, EarlyView.
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.
