Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...

Defect‐Induced Selectivity Modulation Using Copper Triazole Molecular Frameworks for Electrochemical CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
A Cu‐triazole and D‐Cu‐triazole MOF is studied for eCO2RR. After introducing open metal sites and reducing the particle size through a competitive coordination strategy with N,N‐diethylformamide, the defects significantly enhance and alter the catalytic properties with increased selectivity for C2+ products. Abstract Metal–organic frameworks (MOFs) are
