Tuning Pore Size in Porous Graphene Membrane for O2/N2 Separation
Advanced Materials, EarlyView.Single‐layer graphene membranes featuring N‐functionalized, 0D pores offer a promising platform for O2/N2 separation. The heterogeneity of functional groups at the pore edge is dynamically tunable, enabling precise tuning of the pore limiting diameter and gas transport.

Advanced Materials Interfaces, EarlyView.This study investigates the thermochromic properties of VO2 deposited on aluminum doped zinc oxide precoated fused silica with Al2O3, TiO2, and WO3 as interface layers. The results indicate that the metal‐to‐insulator transition is highly influenced by the grains formed at the interface.
