Data for PCCP (2018) paper "Amorphous Phase State Diagrams and Viscosity of Ternary Aqueous Organic/Organic and Inorganic/Organic Mixtures"

A Dimer Collision, Isolation and Coalescence (DCIC) technique is used to probe the phase behaviour and glass transition temperatures of ternary aerosol mixtures. The DCI technique is used to perform temperature and relative humidity dependent viscosity measurements at viscosities near 5 × 106 Pa∙s. These measurements are compared with values from Holographic Optical Tweezer (HOT) measurements taken at room temperature. Measurements include organic-organic and organic-inorganic mixtures of sucrose-citric acid and sucrose-sodium nitrate mixtures. Overall, the viscosities determined from the DCI and HOT techniques are in good agreement. The data reported here add additional insight into the wide discrepancies in glass transition temperatures reported for pure sodium nitrate. The phase diagram model used in the work of Rothfuss and Petters (Phys. Chem. Chem. Phys., 2017, 19, 6532-6545) is expanded to include multiple solute components. Data and model predictions of the mixtures are in good agreement with the modified model.
