ATR-FTIR Measurements of Cationic Surfactant Exchange Rates at the Solid-Liquid Interface
… surfactant adsorption and desorption at solid-liquid interfaces is found to be quite slow, considering that surfactants are small molecules. Attenuated total reflectance Fourier transform infrared spectroscopy was used to study the adsorption, desorption, and exchange of …

Catalytic consequences of inner- and outer-sphere interactions at the solid-liquid interface in zeolites
Catalytic transformations at solid-liquid interfaces are inherently complex, as they require considerations for adsorption, desorption, molecular rearrangement, charger transfer, and dispersive interactions, but also involve interactions mediated by the solvating molecules. The rational design of …
