Dynamic Cages—Towards Nanostructured Smart Materials

Angewandte Chemie, Volume 135, Issue 43, October 23, 2023., 2023
Given their chemical and structural variability, dynamic organic and coordination cage architectures are increasingly being used in the formation of more complex systems—smart materials. In this Review we present basic know‐how for modifying active surfaces with cage systems.

Gradient Elution in Capillary Electrochromatography [PDF]

Analytical Chemistry, 1996
In analogy to pressure-driven gradient techniques in high-performance liquid chromatography, a system has been developed for delivering electroosmotically driven solvent gradients for capillary electrochromatography (CEC). Dynamic gradients with submicroliter per minute flow rates are generated by merging two electroosmotic flows that are regulated by ...
