AS STRUCTURE TRANSFORMATION IN COLLOIDS IN TERRESTRIAL EXPERIMENTS IS INFLUENCED BY DETRIMENTAL GRAVITY EFFECTS SUCH AS BUOYANCY-DRIVEN CONVECTION AND PARTICLE SEDIMENTATION USING EARTH-BASED STUDIES FOR TESTING COLLOIDAL THEORIES IS PROBLEMATIC. TO UNCOVER MECHANISMS GOVERNING PHASE TRANSFORMATIONS A SERIES OF MICROGRAVITY EXPERIMENTS WAS CARRIED OUT OVER THE LAST SEVERAL DECADES IN THE INTERNATIONAL SPACE STATION (ISS) TO STUDY COLLOIDS WITHOUT MASKING GRAVITY EFFECTS. WHILE VIDEO MICROSCOPY AND SMALL-ANGLE LIGHT SCATTERING WERE USED IN ISS STUDIES ONLY LIGHT SCATTERING MEASUREMENTS HAVE BEEN PROCESSED SO FAR TO ANALYZE STRUCTURE TRANSFORMATIONS OBSERVED UNDER MICROGRAVITY. MICROSCOPY METHODS ARE EXTREMELY WELL-SUITED FOR STUDIES OF LARGE-SCALE STRUCTURING IN COLLOIDS. IT IS EXPECTED THAT PROCESSING AND ANALYSIS OF IMAGES RECORDED IN ISS EXPERIMENTS WILL BRING NEW INSIGHT INTO THE FORMATION AND EVOLUTION OF STRUCTURES DURING PHASE TRANSITION IN COLLOIDS. OBJECTIVES: THE MAIN GOAL OF THE PROPOSED RESEARCH IS TO ANALYZE VIDEO MICROSCOPY IMAGES RECORDED IN ISS EXPERIMENTS TO INVESTIGATE LARGE-SCALE STRUCTURING IN A COLLOIDAL SYSTEM UNDERGOING PHASE TRANSITION. THE USE OF EXTENSIVE AND WELL DOCUMENTED SETS OF IMAGES IN THE NASA PHYSICAL SCIENCES INFORMATICS (PSI) SYSTEM IS CRUCIAL PART OF THE PROPOSED PROJECT. ANALYSIS OF THESE IMAGES WILL BE USED TO DEVELOP PHASE-FIELD MODELS FOR STRUCTURING IN COLLOIDS CONSISTENT WITH ISS EXPERIMENTS. METHODOLOGY: IMAGEJ A JAVA-BASED IMAGE PROCESSING PROGRAM DEVELOPED AT THE NATIONAL INSTITUTES OF HEALTH AND MATLAB SCRIPTS WILL BE USED FOR PROCESSING VIDEO MICROSCOPY IMAGES ON COLLOIDS AVAILABLE IN THE NASA PSI SYSTEM. MODELS FOR STRUCTURE TRANSFORMATIONS IN COLLOIDS UNDERGOING PHASE SEPARATION CRYSTALLIZATION AND GELATION WILL BE DEVELOPED WITHIN THE PHASE-FIELD FRAMEWORK. RESULTS OF IMAGE PROCESSING AND EXISTING SMALL-ANGLE LIGHT SCATTERING WILL BE USED FOR RIGOROUS TESTING OF THEORETICAL PREDICTIONS. DELIVERABLES: BETTER UNDERSTANDING OF PHASE TRANSFORMATIONS IN COLLOIDAL SYSTEMS ANALYZED MICROSCOPY IMAGES RECORDED IN ISS EXPERIMENTS PHASEFIELD MODELS FOR PHASE TRANSFORMATIONS IN COLLOIDS AND CODES FOR NUMERICAL COMPUTATIONS OF THE DEVELOPED MODELS.
