Ag‐Regulated Cu‐Sites on a Conductive Cu‐Metal‐Organic Framework for Enhanced CO2 Electroreduction to CH4

EcoEnergy, EarlyView.
We present a strategy of integrating Ag NPs with a 2D Cu3(HHTP)2 framework to boost selective CO2 electroreduction. The optimal composite achieves 65.1% FECH4 ${\text{FE}}_{{\text{CH}}_{4}}$ at 240 mA cm−2. Synergistic effects enhance CO2 adsorption, facilitate electron transfer, and selectively stabilize key reaction intermediates, steering the ...

Trapping a Metastable Node in an Amorphous Metal–Organic Framework

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Frustrated assembly in an amorphous Fe‐BDC framework is shown to trap a distorted, metastable Fe3O node as the dominant local motif. X‐ray PDF analysis and DFT calculations reveal that rapid network percolation outpaces node relaxation, locking in a high‐energy puckered geometry.

Interplay Between Oxidation State, Intervalence Charge Transfer Transitions and Electronic Conductivity in a Series of Ru‐Based Metal–Organic Frameworks

Small, EarlyView.
Ru‐based square‐grid metal–organic frameworks undergo dramatic conductivity enhancements after chemical oxidation. The mixed‐valent states exhibit the highest conductivity values, which correlate with the appearance of intervalence charge transfer bands.

Probing the molecular determinants of emission enhancement in RNA aptamer–metal complex systems

Photochemistry and Photobiology, EarlyView.
Light up aptamer: fluorophore pairs are widely used in sensing and imaging, with coordination complex fluorophores providing specific benefits due to their long‐lived emission. Here, we examined key structural and electronic features of these metal complexes to identify the requirements for productive engagement with an RNA aptamer.

Analysis of Moisture Desorption Isotherms of Eggplant (Solanum melongena) [PDF]

, 2010
Sorption isotherms of eggplant were determined employing, as experimental technique, a static gravimetric method, using saturated salt solutions to achieve the equilibrium. The experiments were carried out at different temperatures (20, 35, 50 and 65 °C)
