For that purpose, we determined the ice melting temperature in pores of various size (pore radii between 1.9 and 11.1 nm) in water and aqueous solutions up to high total solute molality (up to about 12 mol kg–1) using differential scanning calorimetry. We found that both electrolytes reduce the ice melting temperature within the pores. An exception is the melting of ice in the smallest pores, which does not seem to be affected by the presence of solutes, most likely owing to an exclusion of the ions from entering the pores. For all other pores, we observed that the ice melting temperature decreases as a function of pore size and electrolyte concentration. Using thermodynamic considerations as well as additional experimental data we developed a parametrization that can be used to predict the ice melting point as a function of pore size and total solute molality. For that purpose, we extended a formulation of the effective water activity of aqueous solutions under mechanical pressure toward its application in confinement and tested this new parametrization on literature data.","lang":"eng"}],"publication":"The Journal of Physical Chemistry C","date_updated":"2023-03-08T08:31:45Z","title":"Phase Transitions of Ice in Aqueous Salt Solutions within Nanometer-Sized Pores","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"quality_controlled":"1","type":"journal_article","publication_status":"published"}
