Nanoconfined Cu─O─Mo Asymmetric Sites Enable Ambient Spontaneous O2‐to‐1O2 Conversion for Sustainable Water Purification

Advanced Materials, EarlyView.
An asymmetric Cu+─O─Mo6+ dual‐site in a nanoconfined membrane turns O2 into singlet oxygen at ambient conditions with ≈95% selectivity, bypassing superoxide. It concentrates reactants for rapid pollutant removal, operates stably in continuous flow with ultra‐low metal leaching and cost, efficiently purifying complex waters.

Citrate‐Enhanced PCL Scaffolds for Bone Tissue Engineering

Advanced Materials Interfaces, EarlyView.
This study investigates citrate‐enhanced polycaprolactone (PCL) scaffolds designed for bone tissue engineering. Utilizing 3D printing technology, four scaffold patterns (triple hexagon, grid, gyroid, zigzag) are evaluated for mechanical properties, cellular proliferation, osteogenic differentiation, and gene expression.
