Cooperative Agostic‐Type C─H···Cu, Quadrupolar Cu···CO 2 , and C─H···O/π Interactions in an Ultra‐Microporous MOF Enable One‐Step Methane Purification From Quaternary C 3 H 8 /C 2 H 6 /CO 2 /CH 4

ABSTRACT While agostic‐type C─H···metal σ‐interactions are central to organometallic catalysis, their role in gas separation remains elusive. In this study, a robust phosphine‐functionalized ultra‐microporous Cu(I/II)‐organic framework, LIFM‐XYY‐15, featuring open metal sites (OM...

FLASH: Ultrafast Beam Quality Characterization via Spatial‐to‐Temporal Mapping

ABSTRACT Accurate and real‐time monitoring of spatial beam quality is the absolute prerequisite for intelligent optical field regulation and advanced laser applications. However, modern high‐power and multimode laser systems can exhibit rapid pulse‐to‐pulse fluctuations in their...
