Rheological aging and rejuvenation in solid friction contacts

, 2002
We study the low-velocity (0.1--100 $\mu$m.s$^{-1}$) frictional properties of interfaces between a rough glassy polymers and smooth silanized glass, a configuration which gives direct access to the rheology of the adhesive joints in which shear localizes.

Heavy is the Crown: Crown Ether Modulation of Cobalt Porphyrin CO2 Electroreduction in Zero‐Gap Electrolyzers

Angewandte Chemie International Edition, Volume 65, Issue 11, 9 March 2026.
The implementation of crown ethers into the ligand of cobalt porphyrins benefits the electrochemical CO2 reduction in the several ways: (1) the reduction potential is lowered in presence of K+; (2) it boosts the CO generation in Zero‐Gap Electrolyzers and (3) ensures complex stability during electrolysis.
