It contains the raw data for the figures showing, temperature and humidity change in the levitator, heat loss of the heaters in the levitator, schlieren imaging of the heaters, temperature ramps and voltage currents for each temperature, the stability of the droplets at varying temperatures, drying curves and rates for water droplets and the XRD of a phase transition of the surfactant.

PROJECT AND FUNDING INFORMATION ---------------------------------- Title: EPSRC Centre for Doctoral Training in Molecules to Product - Drying of Alpha Olefin Sulphonates: Effect of drying temperature on phase transitions and particle properties Dates: April 2019 - September 2027 Funding organisation: EPSRC in collaboration with Innospec Ltd Grant no.:EP/S022473/1 4. CONTENTS ----------- File listing Raw_data_for_DOI_1b-6b.xlsx The data for each figure is available as individual tabs within the spreadsheet Figure 1b - Temperature change at droplet position when levitator is turned on Figure 2b - Temperature change when levitator is switched on then temperature drop when heater is turned off Figure 4b - Heater ramps within given voltages and currents Figure 4c - Lateral deviation tracking data for water Figure 5a - Data for drying curves diameter squared then normalized diameter over initial diameter squared Figure 5b - Drying rate for water droplets Figure 6a - Time resolved XRD of phase transition at 80 °C of Alpha Olefin Sulfonate Figure 6b - Lateral deviation tracking for Alpha olefin sulfonate droplet Raw images for schlieren.zip All the images taken for back orientated schlieren are contained, reference images are marked for each heater type eg. Flat_heater_ref1.tiff, then 2 alternate images are included for the heater running on it's own Flat_heater_on_1.tiff and a second with the heater and levitator on together Flat_heater_on_Lev_on_1.tiff. 5.
