A Metal-COF-Based SERS Platform for PPb-Level Toluene Sensing With Tailored Metal Selectivity.

Ultrasensitive detection of nonpolar toxic VOCs like toluene remains a great challenge for environmental monitoring. This work presents a rationally designed SERS platform based on metallized covalent organic frameworks (M-COFs, M = Fe, Ni, Cu) obtained by a mild metal-modulation strategy that enables metal‑tunable COF...

The Role of Magnetism and Phonons in the Negative Thermal Expansion of Layered Chromium Telluride

Unraveling the origin of negative thermal expansion (NTE) in magnetic solids remains an open challenge, often obscured by the complex entanglement of spin and lattice dynamics. Here, leveraging the layered architecture of nominally Cr0.95Te, we distinguish the magnetic and phononic contributions to its anomalous ther...
