LIQUID-LIQUID PHASE SEPARATION IN ATMOSPHERICALLY RELEVANT PARTICLES  by Yuan You  B.S., Shanghai Jiao Tong University, 2009  A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF  THE REQUIREMENTS FOR THE DRGREE OF  DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Chemistry)  THE UNIVERISTY OF BRITISH COLUMBIA (Vancouver)  September 2014  © Yuan You, 2014 List of Supplementary Materials Movie 2.1 A movie of a mixed 1,2,6-hexanetriol-ammonium sulfate particle (org:sulf = 2.06 and diameter = 21 µm) recorded using 500  magnification as the RH was decreased from 86% to 35% at a temperature of 290  1 K. The ramp rate was approximately 0.6% RH min–1. Initially the particle was completely liquid (1 liquid phase). Next, liquid-liquid phase separation occurred to form a predominately aqueous ammonium sulfate core and organic shell. After liquid-liquid phase separation the aqueous ammonium sulfate core effloresced. A rough indication of the RH during the movie has been included.  Movie 3.1 A movie of a particle consisting of ammonium sulfate (diameter = 21.6 µm).  Images were recorded as the RH was decreased from 50% to 35% at a temperature of 270  1 K. The ramp rate was approximately 0.6% RH min–1. For the particle shown in this movie, efflorescence occurred at 37.4 ± 4%. A rough indication of the RH during the movie has been included.  Movie 3.2 A movie of a particle consisting of ammonium sulfate (diameter = 21.6 µm).  Images were recorded as the RH was increased from 62 to 80% RH at a temperature of 270  1 K. The ramp rate was approximately 0.6 % RH min–1. For the particle shown in this movie, deliquescence occurred at 78.0 ± 4%.  A rough indication of the RH during the movie has been included.  Movie 3.3 A movie of a particle (org:sulf = 1.4 and diameter = 28.0 µm) consisting of ammonium sulfate mixed with secondary organic material generated by the ozonolysis of α-pinene.  Images were recorded as the RH was decreased from 90% to 35% at a temperature of 270  1 K. The ramp rate was approximately 0.6% RH min–1. For the particle shown in this movie, liquid-liquid phase separation occurred at an RH greater than 90 ± 4% and efflorescence occurred at 40.5 ± 4%. A rough indication of the RH during the movie has been included.  Movie 3.4 A movie of a particle (org:sulf = 1.4 and diameter = 28.0 µm) consisting of ammonium sulfate mixed with secondary organic material generated by the ozonolysis of α-pinene.  Images were recorded as the RH was increased from 60 to 80% RH at a temperature of 270  1 K. The ramp rate was approximately 0.6 % RH min–1. For the particle shown in this movie, complete deliquescence occurred at 77.0 ± 4%. A rough indication of the RH during the movie has been included.  Movie 3.5 A movie of a particle (org:sulf = 1.0 and diameter = 18.3 µm) generated from a filter sample collected August 6-7, 2010 in Atlanta.  Images are shown as the RH was decreased from 68% to 35% at a temperature of 270  1 K. The ramp rate was approximately 0.6% RH min–1. For the particle shown in this movie, liquid-liquid phase separation occurred at an RH greater than 90% ± 4%, while efflorescence occurred at an RH of 37.0 ± 4%. A rough indication of the RH during the movie has been included.  Movie 3.6 A movie of a particle (org:sulf = 1.0 and diameter = 18.3 µm) generated from filter sample collected August 6-7, 2010 in Atlanta.  Images are shown as the RH was increased from 50% to 80% at a temperature of 270  1 K. The ramp rate was approximately 0.6% RH min–1. For the particle shown in this movie, deliquescence occurred at 71.6 ± 4%. A rough indication of the RH during the movie has been included.  Movie 4.1 A movie of a particle consisting of ammonium sulfate and toluene photo-oxidation secondary organic material of org:sulf = 0.1 recorded for decreasing RH at 289 ± 1 K. The RH was decreased from 90% to 30% at a rate of 0.5% RH min-1. A rough indication of the RH during the movie has been included. This movie was taken from Smith et al. 2013, and copyright from American Chemical Society 2013.   Movie 4.2 A movie of a particle consisting of ammonium sulfate and toluene photo-oxidation secondary organic material of org:sulf = 3.0 recorded for decreasing RH at 289 ± 1 K. The RH was decreased from 90% to 30% at a rate of 0.5% RH min-1 and from 30% to < 0.5% at a rate of 4-5% RH min-1. A rough indication of the RH during the movie has been included. This movie was taken from Smith et al. 2013, and copyright from American Chemical Society 2013.   Movie 5.1 A movie of a particle (OIR = 2.0 and diameter = 28.0 μm) consisting of 2-methylglutaric acid and ammonium sulfate. Images were recorded as the RH was decreased from 79% to 72% at a temperature of 290 ± 1 K. The ramp rate was approximately 0.6% RH min–1. For the particle shown in this movie, liquid-liquid phase separation occurred at an RH 75 ± 2.5%. A rough indication of the RH during the movie has been included.   Movie 5.2 A movie of a particle (OIR = 2.0 and diameter = 32.3 μm) consisting of 2-methylglutaric acid and ammonium bisulfate. Images were recorded as the RH was decreased from 70% to 60% at a temperature of 290 ± 1 K. The ramp rate was approximately 0.6% RH min–1. For the particle shown in this movie, liquid-liquid phase separation occurred at an RH 65.5 ± 2.5%. A rough indication of the RH during the movie has been included.   Movie 5.3 A movie of a particle (OIR = 2.1 and diameter = 33.6 μm) consisting of 2-methylglutaric acid and sodium chloride. Images were recorded as the RH was decreased from 65% to 55% at a temperature of 290 ± 1 K. The ramp rate was approximately 0.6% RH min–1. For the particle shown in this movie, liquid-liquid phase separation occurred at an RH 60.2 ± 2.5%. A rough indication of the RH during the movie has been included.  Movie 5.4 A movie of a particle (OIR = 2.0 and diameter = 32.3 μm) consisting of 2-methylglutaric acid and ammonium nitrate. Images were recorded as the RH was decreased from 43% to 27% at a temperature of 290 ± 1 K. The ramp rate was approximately 0.6% RH min–1. For the particle shown in this movie, liquid-liquid phase separation occurred at an RH 35.3 ± 2.5%. A rough indication of the RH during the movie has been included.
