TL;DR: It is demonstrated that the variety of geometries in which the microfluidic/nanofluidic interfaces are realized share common, fundamental features of coupled mass and charge transport, but that phenomena behind the key steps in a particular application can be significantly tuned, depending on the morphology of a material.

TL;DR: The presented approach defines a strictly scientific route to the key morphology-transport relationships of current and future chromatographic supports, including their morphological reconstruction, statistical analysis, and the correlation with relevant transport phenomena.

TL;DR: A new generation of analytical silica monoliths are presented that deliver a substantially improved separation efficiency achieved through several advances in monolith morphology and possess not only smaller macropores, a more homogeneous macropore space, and a thinner silica skeleton, but also radial homogeneity of these structural parameters as well as of the local external or macroporosity.

TL;DR: The demonstrated intrinsic influence of the PSD on dispersion in bulk packings is negligible compared with the influence ofThe bed porosity, and the reduced eddy dispersion observed for experimental core-shell packings cannot be attributed to a narrow PSD per se.
