An Atomic‐Level Bimetallic MOF Platform Overcoming the Stability‐Performance Tradeoff for Laser Propulsion

open access: yesAdvanced Materials, EarlyView.
This work introduces an atomic‐level engineered bimetallic MOF Platform that resolves the inherent trade‐off between environmental stability and propulsion efficiency. By integrating robust Fe‐O bonds for hydrolysis resistance and enabling d‐orbital charge transfer (Fe3+→Cu2+) for enhanced photothermal conversion, the design achieves a highly durable ...

Undercoordinated Molybdenum Catalysts Enable Ultrafast Quasi‐Solid Sulfur Chemistry in Sodium‐Sulfur Batteries

open access: yesAdvanced Materials, EarlyView.
An unsaturated coordination chemistry strategy activates a quasi‐solid‐state redox pathway by strengthening NaPSs adsorption and accelerating redox conversion kinetics, thereby overcoming the kinetic bottlenecks that limit high‐rate performance. In situ transmission electron microscopy, combined with newly developed Na‐ion diffusion descriptors ...

Experimental Evidence of Free Carrier Generation in 2D Hybrid Organic–Inorganic Perovskites

open access: yesAdvanced Optical Materials, EarlyView.
ABSTRACT Despite the significant potential of 2D hybrid organic–inorganic perovskites (2DHOIPs) for high‐efficiency optoelectronics application‐comparable to their 3D counterparts, the fundamental carrier photogeneration remains unclear. In contrast to conventional ultrafast optical property characterization, we use ultrafast photocurrent spectroscopy ...

Space Group Modulated Upconversion and Mechanoluminescence in [YbEu] Cocrystal Complexes

open access: yesAdvanced Optical Materials, EarlyView.
We report here a space group regulation strategy to optimize both upconversion and mechanoluminescence in cocrystal assemblies, representing the first example of integrating these two properties within a single lanthanide complex material. ABSTRACT Lanthanide complexes exhibiting stimuli‐responsive luminescence, such as upconversion (UC) and ...
