A temperature programmed desorption study of interactions between water and hydrophobes at cryogenic temperatures

Abstract

Interactions of water with D2, Ne, Ar, CH4, C3H8, and Xe were investigated based on TPD to gain insight into hydrophobic hydration at cryogenic temperatures.

Influences of 1-Propanol and Methanol Additives on Crystallization of Thin Amorphous Solid Water Films

“…The same situation is expected to occur when hydrated alcohol species are present near the interfacial region of Pt(111) because mobility of water in direct contact with the substrate can be improved via interactions with the hydrophobic moiety of hydrated alcohols. In contrast to the alcohol additives, nonpolar additives have no apparent effects on the water’s crystallization kinetics and the growth mode of ice. , Probably, this occurs because hydrophobes are stabilized in the film interior via the cage formation without segregation to the interfacial regions . Consequently, it is thus demonstrated that the alcohol additives modify the crystallization kinetics of thin LDL films at the free surface and substrate interface because of their amphiphilic nature.…”

In any case, the crystallization of pure water initiates in the bulk via homogeneous nucleation, as evidenced by the fact that pure ASW 20−23 and HGW 41 crystallize commonly at about 160 K regardless of the water film thickness.…”
