Die Absorption. Das Wasser in den Kolloïden, besonders in dem Gel der Kieselsäure

A simple model and experiments for adsorption‐desorption hysteresis: Water vapor on silica gel

“…It exhibits considerable hysteresis with many adsorbates including water vapor. Van Bemmelen first reported hysteresis in the adsorption of water on silica gel almost 100 years ago (Van Bemmelen, 1897). An excellent review of the experimental data on hysteresis, particularly on the water-silica gel system, is given by Gregg and Sing (1982).…”

Anomalous Molecular Dynamics in Confined Spaces

“…Though known since a century [65], the phenomenon of adsorption hysteresis is still a subject of controversial discussion [66][67][68][69]. Only very recently, NMR has been recollected and applied as a powerful tool to contribute to an eventual clarification of the underlying phenomena.…”

On the theory of capillary evaporation in porous bodies

“…Thousands of articles devoted to explanation, study, and application of the discussed phenomenon lie between the first publication of von Bammelen on capillary condensation in porous bodies [1] and the latest review in this field [2]. In the modern literature [3][4][5][6][7], capillary condensation is often associated with the reverse evaporation process, which is sometimes called capillary evaporation [4][5][6][7].…”
